UK LGV Theory Test (Driver CPC Part 1) — Questions and Answers
Question 1: What must an ADR driver do before parking a dangerous goods vehicle overnight?
- Park in a safe, secure location away from public areas, public buildings, and crowds — preferably an approved ADR parking area (Correct answer)
- Only avoid parking near petrol stations
- Park at the nearest lorry park regardless of proximity to buildings
- No specific ADR parking rules apply overnight
Correct answer: Park in a safe, secure location away from public areas, public buildings, and crowds — preferably an approved ADR parking area
ADR requires that dangerous goods vehicles be parked safely and securely. They should be kept away from residential areas, public buildings, crowds, and open flames. Operators should use secure, supervised parking areas when available.
Question 2: Why is it important to ensure the trailer is at the correct height before coupling?
- Height does not matter for coupling
- If too high, the kingpin may ride over the jaws; if too low, it may not engage properly or could damage the trailer plate (Correct answer)
- For aesthetic reasons
- Only to make it easier to connect the air lines
Correct answer: If too high, the kingpin may ride over the jaws; if too low, it may not engage properly or could damage the trailer plate
The trailer must be at the correct height for the 5th wheel to slide smoothly under the trailer plate and for the kingpin to drop into the jaws. Too high and the kingpin may not engage; too low and the 5th wheel could strike and damage the trailer underside.
Question 3: What is the correct first step when uncoupling a semi-trailer?
- Disconnect the air lines first
- Drive forward quickly to separate
- Apply the trailer parking brake and lower the landing gear until they are firmly supporting the trailer weight (Correct answer)
- Release the 5th wheel lock immediately
Correct answer: Apply the trailer parking brake and lower the landing gear until they are firmly supporting the trailer weight
The first step is to apply the trailer parking brake and lower the landing gear until they take the weight of the trailer. This ensures the trailer is stable and supported before the tractor is removed. Never release the coupling before the trailer is independently supported.
Question 4: What does a double white line in the centre of the road where the nearest line is solid mean?
- You may cross if your side is broken
- You should cross to allow emergency vehicles to pass
- It is advisory only for LGVs
- You must not cross or straddle the line (Correct answer)
Correct answer: You must not cross or straddle the line
Where the line nearest to you is solid (double white lines), you must not cross or straddle it. This applies regardless of vehicle type, including LGVs.
Question 5: In heavy rain, what is the safest action an LGV driver can take to protect other road users?
- Flash headlights to warn approaching vehicles
- Reduce speed and greatly increase the following distance (Correct answer)
- Sound the horn at every junction
- Activate hazard warning lights continuously
Correct answer: Reduce speed and greatly increase the following distance
Reducing speed and increasing following distance makes the vehicle safer and more predictable to other road users in heavy rain conditions.
Question 6: What is the overall stopping distance for a vehicle travelling at 60 mph in ideal conditions (thinking distance plus braking distance)?
- 91 metres
- 55 metres
- 73 metres (240 feet) (Correct answer)
- 60 metres
Correct answer: 73 metres (240 feet)
At 60 mph, the thinking distance is approximately 18 metres and the braking distance approximately 55 metres, giving an overall stopping distance of around 73 metres (240 feet) in ideal conditions. For a loaded LGV, this will be significantly greater.
Question 7: What does a yellow or amber engine warning light on the dashboard typically indicate?
- A minor issue that can be ignored
- An engine management fault that should be investigated at the earliest opportunity (Correct answer)
- The engine is about to fail and must be stopped immediately
- The oil change is due
Correct answer: An engine management fault that should be investigated at the earliest opportunity
An amber engine warning light indicates an engine management fault, often related to emissions systems (EGR, DPF, AdBlue). It should be investigated soon but does not normally require an immediate stop, unlike a red warning light.
Question 8: What stopping distance should an LGV driver aim to maintain in fog?
- 50 metres regardless of speed
- Be able to stop within the distance they can see — if visibility is 20 metres, stopping distance must be within 20 metres (Correct answer)
- Double the normal dry-weather stopping distance
- Triple the 2-second gap rule
Correct answer: Be able to stop within the distance they can see — if visibility is 20 metres, stopping distance must be within 20 metres
In fog, the driver must be able to stop within the visible distance. If visibility is 20 metres, speed must be reduced so that stopping is possible within 20 metres. Driving faster than visibility allows is sometimes called 'overdriving your headlights'.
Question 9: What does 'payload' mean in the context of goods vehicle operation?
- The total gross weight of the vehicle and load
- The weight of the vehicle only
- The maximum weight of cargo the vehicle can carry — gross weight minus unladen vehicle weight (Correct answer)
- The number of pallets the vehicle can carry
Correct answer: The maximum weight of cargo the vehicle can carry — gross weight minus unladen vehicle weight
Payload is the weight available for cargo: gross weight minus the vehicle's own unladen weight. Drivers must know their vehicle's unladen weight to calculate how much cargo can be legally loaded.
Question 10: Can a driver interrupt their daily rest period under EU rules?
- Only if travelling by ferry or train — the rest can be interrupted twice for boarding/alighting (Correct answer)
- Yes, for meal breaks only
- Never — the rest must be uninterrupted
- Yes, as many times as they want
Correct answer: Only if travelling by ferry or train — the rest can be interrupted twice for boarding/alighting
A regular daily rest can be interrupted no more than twice for the purpose of boarding or leaving a ferry or train, provided the driver has access to a bunk or couchette. Each interruption must not exceed one hour, and the total rest must still be 11 hours.
Question 11: Under ADR, what does Class 2 dangerous goods cover?
- Only compressed gases
- Only flammable gases
- Gases — including flammable gases, non-flammable non-toxic gases, and toxic gases (Correct answer)
- Only cryogenic gases
Correct answer: Gases — including flammable gases, non-flammable non-toxic gases, and toxic gases
ADR Class 2 covers all gases, divided into three categories: 2.1 Flammable gases (e.g., LPG, hydrogen), 2.2 Non-flammable non-toxic gases (e.g., compressed air, carbon dioxide), and 2.3 Toxic gases (e.g., chlorine, ammonia).
Question 12: When securing a load using straps with ratchet tensioners, what is the correct tensioning procedure?
- Use a torque wrench to achieve precise tension
- Tension only to the point where the strap does not sag
- Tension until the strap is taut and firm — do not over-tension to the point of damaging cargo or exceeding the WLL (Correct answer)
- Tighten as hard as possible for maximum security
Correct answer: Tension until the strap is taut and firm — do not over-tension to the point of damaging cargo or exceeding the WLL
Ratchet straps should be tensioned until they are firm and the load does not move when pushed. Over-tensioning can damage soft cargo, distort the vehicle structure, or exceed the strap's WLL. The correct tension is firm but not excessively tight.
Question 13: What is brake hysteresis?
- The time taken to replace brake pads
- The difference between braking force during application and release — important for smooth, controlled braking (Correct answer)
- A type of brake disc
- The sound brakes make when applied
Correct answer: The difference between braking force during application and release — important for smooth, controlled braking
Brake hysteresis is the difference between the braking force during brake application and during brake release at the same pedal pressure. Good hysteresis provides smooth, progressive control. Poor hysteresis causes 'snatchy' brakes that are difficult to modulate.
Question 14: When should the electrical connections (suzi coils) be connected during coupling?
- Electrical connections are not needed
- Before approaching the trailer
- After the mechanical coupling is confirmed secure and air lines are connected (Correct answer)
- Only when carrying refrigerated loads
Correct answer: After the mechanical coupling is confirmed secure and air lines are connected
Electrical connections (for lights, ABS, EBS) should be connected after the mechanical coupling and air lines are confirmed secure. This ensures the trailer lights and electronic brake systems are functional before driving.
Question 15: What is the impact of fatigue on LGV driving performance on long motorway journeys?
- Impact of fatigue is minimal at steady motorway speeds
- Energy drinks fully counter the effects of fatigue while driving
- Fatigue severely impairs reaction time, decision-making, and lane keeping — drivers must take regular breaks (Correct answer)
- Only affects driving after 12 continuous hours
Correct answer: Fatigue severely impairs reaction time, decision-making, and lane keeping — drivers must take regular breaks
Fatigue is one of the most dangerous factors in HGV accidents. Monotonous motorway driving accelerates fatigue onset. Reaction times slow, lane keeping deteriorates, and micro-sleeps can occur. Regular breaks (as required by tachograph rules) are essential.
Question 16: After the 5th wheel has engaged with the trailer kingpin, what test must the driver perform?
- A speed test
- A horn test
- A pull test (tug test) — gently try to pull away with the trailer brakes applied to confirm the coupling is locked (Correct answer)
- A fuel economy test
Correct answer: A pull test (tug test) — gently try to pull away with the trailer brakes applied to confirm the coupling is locked
The driver must perform a pull test by applying the trailer brakes and gently attempting to drive forward. If the coupling is properly locked, the tractor will not separate from the trailer. This confirms the jaws are fully closed around the kingpin.
Question 17: What does a motorway sign showing a petrol pump symbol with a mileage indicate?
- A lorry fuel depot at that distance
- Services with fuel are available at that distance ahead (Correct answer)
- Fuel is compulsory for LGVs at that point
- A weigh bridge with fuel at that distance
Correct answer: Services with fuel are available at that distance ahead
Signs with a petrol pump symbol and distance indicate motorway service areas with fuel ahead. LGV drivers should plan fuel stops carefully as fuel consumption on motorways is significant and services can be widely spaced.
Question 18: What does a sign showing '6'6"' with height indication mean for an LGV driver?
- A speed limit of 6.6 mph
- Maximum vehicle length of 6.6 metres
- A low bridge or height restriction ahead — vehicles taller than the height shown must not pass (Correct answer)
- The road is 6.6 metres wide
Correct answer: A low bridge or height restriction ahead — vehicles taller than the height shown must not pass
Height restriction signs (shown in feet and inches, and/or metres) indicate a low bridge or structure ahead. LGV drivers must know their vehicle's height and must not attempt to pass if their vehicle exceeds the restriction. Bridge strikes are costly and dangerous.
Question 19: What is a 'packing group' in ADR?
- The maximum weight per package
- The type of container used for packing
- The number of packages in a consignment
- A classification (I, II, or III) indicating the danger level of the goods — Group I is most dangerous (Correct answer)
Correct answer: A classification (I, II, or III) indicating the danger level of the goods — Group I is most dangerous
Packing groups (I, II, III) classify the degree of danger within a class. Group I substances are highly dangerous, Group II are medium danger, and Group III are low danger. The packing group determines the packaging standards required.
Question 20: During a pre-departure check, why must a driver check that all doors, hatches, and access panels are properly closed?
- Open panels can cause wind resistance, damage to other vehicles, and are a legal requirement (Correct answer)
- Just a courtesy check — not legally required
- Only relevant for refrigerated trailers
- Only check the rear doors
Correct answer: Open panels can cause wind resistance, damage to other vehicles, and are a legal requirement
All access panels and doors must be properly secured. Open doors can strike other road users, create dangerous air turbulence, allow load to fall, and are a roadworthiness requirement. The driver is responsible.
Question 21: What colour is the background of the ADR warning placard for flammable liquids (Class 3)?
- Red (Correct answer)
- Green
- Orange
- Yellow
Correct answer: Red
Class 3 flammable liquid ADR placards have a red background with a flame symbol. Red is the internationally recognised colour for fire hazard in the ADR/GHS labelling system.
Question 22: During a pre-departure check, a driver finds a tyre has a bulge on the sidewall. What must they do?
- Report it at the end of the shift
- Drive carefully at reduced speed to the nearest tyre centre
- Inflate the tyre to maximum pressure
- Do not drive — a bulged tyre must be replaced immediately (Correct answer)
Correct answer: Do not drive — a bulged tyre must be replaced immediately
A bulge on a tyre sidewall indicates internal structural damage. The tyre could fail catastrophically at any time and especially under load or speed. The vehicle must not be driven until the tyre is replaced.
Question 23: How often must an LGV undergo a statutory annual test (MOT)?
- Every 6 months
- Every 12 months (vehicles over 3.5 tonnes MAM) (Correct answer)
- Only when the operator deems necessary
- Every 2 years
Correct answer: Every 12 months (vehicles over 3.5 tonnes MAM)
Goods vehicles over 3.5 tonnes maximum authorised mass must pass an annual test (MOT) every 12 months. The vehicle must not be used on public roads without a valid test certificate.
Question 24: What is 'progressive braking' and why is it important for LGV drivers?
- Gradually increasing brake pressure to slow smoothly — prevents wheel lock-up, jack-knife, and cargo shift (Correct answer)
- Using only the engine brake and avoiding the footbrake
- Pulsing the brakes to prevent lock-up (same as pumping)
- Maximum brake application from the beginning
Correct answer: Gradually increasing brake pressure to slow smoothly — prevents wheel lock-up, jack-knife, and cargo shift
Progressive braking involves gradually increasing brake pressure from light to heavier application. This gives time for brake balance systems (EBS) to adjust, prevents cargo from shifting, and reduces jack-knife risk. It is a fundamental professional driving technique.
Question 25: What is a 'retarder' on a modern LGV?
- A device that reduces engine power
- An automatic speed limiter
- An auxiliary braking device (hydraulic or electromagnetic) that supplements the main brakes, especially on long descents (Correct answer)
- A braking system that replaces ABS
Correct answer: An auxiliary braking device (hydraulic or electromagnetic) that supplements the main brakes, especially on long descents
A retarder is an auxiliary braking system fitted to many modern LGVs. Hydraulic retarders use fluid resistance and electromagnetic retarders use electromagnetic drag. Both slow the vehicle without using the main friction brakes, preserving them for emergency use.
Question 26: How long must tachograph records be kept by the driver?
- 14 days
- The current month only
- The current week and the last day of the previous week (Correct answer)
- 28 days
Correct answer: The current week and the last day of the previous week
Drivers must carry tachograph records (or printouts) for the current week and the record for the last day of the previous week on which they drove. Digital records are stored on the card.
Question 27: What is a 'Smart' (second generation) tachograph's main additional feature compared to older digital tachographs?
- It prevents driving if rest rules have been breached
- It automatically calls emergency services if an accident occurs
- It communicates remotely and uses GNSS (GPS) to record location data (Correct answer)
- It directly submits data to DVSA
Correct answer: It communicates remotely and uses GNSS (GPS) to record location data
Second generation (Smart) tachographs use GNSS (global navigation satellite system) for location recording and can communicate remotely via DSRC (Dedicated Short Range Communications). They record location data at the start and end of each journey.
Question 28: What should an ADR driver do in the event of a fire involving the vehicle or load?
- Remove the Kemler plates before calling emergency services
- Continue driving to a fire station
- Evacuate to a safe distance, call emergency services, and do not attempt to fight a fire involving the dangerous goods themselves (Correct answer)
- Attempt to extinguish the fire using the vehicle's fire extinguisher regardless of the substance
Correct answer: Evacuate to a safe distance, call emergency services, and do not attempt to fight a fire involving the dangerous goods themselves
In a fire involving dangerous goods, the driver should evacuate to a safe distance (at least 300 metres for most substances), keep people away, call emergency services and give them the transport document and written instructions, and not attempt to fight the fire if it involves the dangerous substance.
Question 29: When a police officer faces you with their right arm extended, what does this mean?
- Slow down
- Proceed with caution
- Stop — you must not proceed (Correct answer)
- Move to the left
Correct answer: Stop — you must not proceed
When a police officer faces you and raises their right arm, you must stop. This is a legally binding signal that overrides traffic signals and road signs.
Question 30: What is the maximum driving time allowed for a driver in any two consecutive weeks?
- 90 hours (Correct answer)
- 112 hours
- 100 hours
- 96 hours
Correct answer: 90 hours
In any two consecutive weeks, total driving must not exceed 90 hours. This is the fortnightly limit and applies regardless of how the hours are distributed across the two weeks.
Question 31: What is the purpose of the trailer service line (yellow coupling)?
- To provide air for the trailer tyres
- To supply emergency air to the trailer
- To supply electricity to the trailer
- To supply air pressure that operates the trailer service brakes when the driver presses the brake pedal (Correct answer)
Correct answer: To supply air pressure that operates the trailer service brakes when the driver presses the brake pedal
The service line (yellow) transmits air pressure from the tractor's braking system to operate the trailer's service brakes. When the driver presses the brake pedal, air pressure is sent through this line to apply the trailer brakes proportionally.
Question 32: What information does a motorway gantry sign showing a red 'X' above a lane provide?
- There is a junction exit in this lane
- The lane is closed — you must not travel in this lane (Correct answer)
- The lane has a speed camera
- The lane is reserved for emergency vehicles only
Correct answer: The lane is closed — you must not travel in this lane
A red 'X' on a motorway gantry sign means the lane is closed and must not be used. This could be due to an incident, breakdown, or roadworks. Driving in a lane marked with a red 'X' is illegal and extremely dangerous.
Question 33: What should an LGV driver check regarding the coupling before driving a trailer?
- Only inspect if the trailer is loaded
- Check visually from inside the cab
- Only that the coupling sounds engaged
- That the coupling is fully engaged, safety locks are in place, and trailer brake connections are secure (Correct answer)
Correct answer: That the coupling is fully engaged, safety locks are in place, and trailer brake connections are secure
Before driving with a trailer, the driver must physically check that the kingpin coupling is fully engaged with the fifth wheel, safety locks (jaws) are closed, trailer brake airline and electrical connections are secure, and trailer legs are fully raised.
Question 34: What does 'Class 8 — Corrosives' mean in ADR terms?
- Substances that cause burns only on skin contact
- Substances that can destroy living tissue and damage metals — including acids and alkalis (Correct answer)
- Substances that are only corrosive to metals
- Any substance with a pH below 7
Correct answer: Substances that can destroy living tissue and damage metals — including acids and alkalis
ADR Class 8 covers corrosive substances that can cause full-thickness destruction of skin tissue and/or are significantly corrosive to metals. This includes strong acids (sulphuric, hydrochloric) and strong alkalis (sodium hydroxide). Special packaging and handling precautions apply.
Question 35: Under the EU drivers' hours rules, what is a 'week' defined as?
- A period beginning at the start of the first shift
- Any consecutive 7-day period
- Monday to Friday only
- The period from 00:00 Monday to 24:00 Sunday (Correct answer)
Correct answer: The period from 00:00 Monday to 24:00 Sunday
Under EU Regulation 561/2006, a 'week' is defined as the period from 00:00 on Monday to 24:00 on Sunday. This is important for calculating weekly driving limits and weekly rest.
Question 36: What happens to tachograph data if there is a power failure to the recording unit?
- All data is lost permanently
- The vehicle automatically stops
- An alarm sounds and driving is prohibited
- The data is stored in internal memory and the driver must make a manual record (Correct answer)
Correct answer: The data is stored in internal memory and the driver must make a manual record
Digital tachographs have internal memory that retains data during a power failure. The driver must also make a manual record of activities on a printout or annotation if the unit malfunctions.
Question 37: What is 'hazard perception' in the context of LGV driving?
- Knowing the vehicle's dimensions
- The skill of identifying and responding to developing hazards early enough to take safe action (Correct answer)
- Understanding the Highway Code rules
- The ability to see road signs clearly
Correct answer: The skill of identifying and responding to developing hazards early enough to take safe action
Hazard perception is the ability to scan the road environment, identify potential hazards (situations that may require a change in speed or direction), and respond early enough to take appropriate, safe action. It is a critical skill tested in the LGV theory test.
Question 38: What personal protective equipment (PPE) must be carried in an ADR vehicle's emergency equipment kit?
- Chemical-resistant full-body suit for all loads
- Fire-resistant overalls
- Warning vest, eye protection (goggles), suitable gloves, and in some cases a breathing protection device (Correct answer)
- Hard hat and steel-toe-cap boots only
Correct answer: Warning vest, eye protection (goggles), suitable gloves, and in some cases a breathing protection device
ADR requires certain PPE to be carried: a warning (high-visibility) vest, eye protection, appropriate gloves, and additional items depending on the substance (such as a breathing protection device for certain classes). The written instructions specify required PPE.
Question 39: When must a load that overhangs the front of a vehicle be marked?
- When it extends beyond the cab
- When it extends beyond 1 metre from the front axle
- Front overhang is never permitted
- When the overhang exceeds 2 metres beyond the front of the vehicle (Correct answer)
Correct answer: When the overhang exceeds 2 metres beyond the front of the vehicle
Front overhang of up to 2 metres beyond the front of the vehicle does not require special marking. Beyond 2 metres, it must be marked with an end marker board or light. Larger overhangs require abnormal load procedures.
Question 40: How does road camber affect an LGV's braking distance?
- Road camber has no effect on braking for air-braked vehicles
- Camber only affects steering, not braking
- Adverse camber (leaning away from the bend) can reduce cornering grip and extend effective braking distance (Correct answer)
- Positive camber always reduces braking distance
Correct answer: Adverse camber (leaning away from the bend) can reduce cornering grip and extend effective braking distance
Road camber affects the load distribution on tyres. Adverse camber (leaning away from a bend) shifts weight onto the outer tyres and reduces overall grip. When combined with braking, this can increase stopping distance and cause instability.
Question 41: What happens if a driver takes a reduced weekly rest period?
- Reduced weekly rests are not permitted
- The reduced rest can only be taken at home
- The reduction must be compensated by an equivalent rest attached to another rest of at least 9 hours within the following 3 weeks (Correct answer)
- No compensation is needed
Correct answer: The reduction must be compensated by an equivalent rest attached to another rest of at least 9 hours within the following 3 weeks
A reduced weekly rest (minimum 24 hours instead of 45 hours) is permitted every other week. However, the reduction (the difference between 45 hours and the actual rest taken) must be compensated en bloc and attached to a rest period of at least 9 hours within the following three weeks.
Question 42: What must a driver do if their tachograph malfunctions?
- Switch to the spare tachograph unit
- Report to DVSA and wait for authorisation to continue
- Make manual records on paper and have the unit repaired within 7 days (Correct answer)
- Stop driving immediately
Correct answer: Make manual records on paper and have the unit repaired within 7 days
If the tachograph malfunctions, the driver must make manual records of their activities on paper (printout or back of tachograph chart). The unit must be repaired at an approved fitter within 7 days of return to base.
Question 43: What is the purpose of a tachograph analysis check?
- To record vehicle faults
- To calculate driver pay
- To calculate fuel consumption
- To verify drivers comply with hours rules and detect infringements (Correct answer)
Correct answer: To verify drivers comply with hours rules and detect infringements
Tachograph analysis examines records to ensure drivers are complying with driving time, break, and rest regulations. Operators must regularly analyse records to detect and address any infringements.
Question 44: What is the '12-day rule' for coach/bus drivers?
- Drivers must rest for 12 days between trips
- The vehicle must be serviced every 12 days
- Drivers can work 12 hours per day
- Drivers on a single international passenger service may postpone their weekly rest for up to 12 consecutive 24-hour periods (Correct answer)
Correct answer: Drivers on a single international passenger service may postpone their weekly rest for up to 12 consecutive 24-hour periods
The 12-day rule allows drivers on a single international passenger service to postpone their weekly rest for up to 12 consecutive 24-hour periods under specific conditions, provided compensation rest is taken afterwards. This does not apply to goods vehicle drivers.
Question 45: What is the Highway Code's stopping distance at 30 mph?
- 30 metres
- 18 metres
- 23 metres (75 feet) (Correct answer)
- 14 metres
Correct answer: 23 metres (75 feet)
At 30 mph, the Highway Code gives a total stopping distance of 23 metres (75 feet): 9 metres thinking distance plus 14 metres braking distance. This is for a car in ideal conditions — a loaded LGV would need considerably more.
Question 46: What is the recommended following distance for an LGV at 60 mph on a dry motorway?
- At least a 2-second gap — but significantly more due to the vehicle's weight and longer stopping distance (Correct answer)
- 1 second per 10 mph (6 seconds at 60 mph)
- Exactly 2 seconds — the same as for any vehicle
- 50 metres minimum
Correct answer: At least a 2-second gap — but significantly more due to the vehicle's weight and longer stopping distance
The 2-second rule gives a minimum for cars, but heavily loaded LGVs have far longer stopping distances. Professional LGV drivers are trained to maintain much greater gaps — often 4-6 seconds or more — because their stopping distances can be 2-3 times longer than cars.
Question 47: Under EU rules, what is the minimum weekly rest period?
- 36 consecutive hours
- 45 consecutive hours (Correct answer)
- 48 consecutive hours
- 24 consecutive hours
Correct answer: 45 consecutive hours
The minimum regular weekly rest is 45 consecutive hours. A reduced weekly rest of 24 hours is permitted but must be compensated for by an equivalent period of rest taken before the end of the third week.
Question 48: What is checked when testing the vehicle's horn during a walkaround inspection?
- That it meets a specific decibel level
- Horns are tested only during annual MOT
- That it sounds and is loud enough to be heard by other road users (Correct answer)
- Only that it has electrical power
Correct answer: That it sounds and is loud enough to be heard by other road users
The horn must sound clearly and be audible. A working horn is a legal requirement. The driver should briefly sound it in a safe area to confirm it operates.
Question 49: How should an LGV driver check tyre pressure is correct?
- Tap the tyres with a hammer
- Check visually for obvious deflation only
- Use a calibrated tyre pressure gauge when tyres are cold (Correct answer)
- Ask the depot fitter to check monthly
Correct answer: Use a calibrated tyre pressure gauge when tyres are cold
Tyre pressure must be checked with a calibrated pressure gauge when tyres are cold (before driving). Visual checks alone are not sufficient as a tyre can lose significant pressure without appearing flat.
Question 50: What is a drawbar coupling and how does it differ from a 5th wheel?
- A drawbar is only used on cars
- A drawbar couples a full trailer to a rigid vehicle using a pin and jaw, allowing the trailer to run on its own wheels at both ends (Correct answer)
- A drawbar is another name for the kingpin
- There is no difference
Correct answer: A drawbar couples a full trailer to a rigid vehicle using a pin and jaw, allowing the trailer to run on its own wheels at both ends
A drawbar coupling connects a full trailer (with axles at both ends) to a rigid vehicle using an eye/pin arrangement. Unlike a 5th wheel where the tractor carries trailer weight, a drawbar trailer supports its own weight. Maximum combination length is 18.75 metres.
Question 51: When driving an LGV in strong crosswinds, which situation creates the greatest risk of the vehicle being blown off course?
- Lightly loaded or unladen with a high-sided body (Correct answer)
- Driving on a sheltered urban road
- Driving slowly on a motorway
- Fully loaded with a low centre of gravity
Correct answer: Lightly loaded or unladen with a high-sided body
A lightly loaded or unladen high-sided LGV presents a large surface area to the wind with little weight to resist it, making it highly vulnerable to crosswinds.
Question 52: When a driver takes a 45-minute break, can they split it?
- No: it must be taken as one continuous 45-minute break
- Yes: first 15 minutes then 30 minutes, in that order only (Correct answer)
- Yes: 20 minutes then 25 minutes
- Yes: any two periods totalling 45 minutes
Correct answer: Yes: first 15 minutes then 30 minutes, in that order only
The 45-minute break can be split into two parts: the first must be at least 15 minutes and the second must be at least 30 minutes, and they must be taken in that order. The order cannot be reversed.
Question 53: What is the minimum break required after 5.5 hours of driving under GB domestic rules?
- 15 minutes
- 60 minutes
- 45 minutes
- 30 minutes (Correct answer)
Correct answer: 30 minutes
Under GB domestic drivers' hours rules, a driver must take a break of at least 30 minutes after no more than 5.5 hours of driving.
Question 54: What should a driver check about the trailer kingpin before coupling?
- That it is not worn, bent, or cracked, and that the trailer plate is not damaged (Correct answer)
- Nothing — the kingpin is maintenance-free
- That it is rusty — rust means it is strong
- Only its colour
Correct answer: That it is not worn, bent, or cracked, and that the trailer plate is not damaged
The kingpin should be inspected for wear, bending, cracking, or damage. The trailer coupling plate should also be checked for cracks or distortion. A worn or damaged kingpin may not lock securely in the 5th wheel jaws.
Question 55: What does a white rectangular sign reading 'END' on a motorway overhead gantry mean?
- End of smart motorway zone
- The variable speed limit or motorway restriction ends at that point (Correct answer)
- End of the overtaking restriction for LGVs
- The motorway ends ahead
Correct answer: The variable speed limit or motorway restriction ends at that point
An 'END' sign on a motorway gantry indicates that a variable speed restriction or mandatory requirement (such as a reduced speed limit in a roadwork zone) has ended. Normal motorway rules and limits resume.
Question 56: What is the purpose of the 'working load limit' (WLL) marked on load securing equipment?
- The breaking strength of the equipment
- The maximum weight the strap can hold vertically
- The total weight of cargo it can secure on its own
- The maximum force the equipment is rated to withstand in normal use (Correct answer)
Correct answer: The maximum force the equipment is rated to withstand in normal use
The WLL is the maximum force the securing device (strap, chain, etc.) is designed to restrain in normal conditions. It is typically one-third of the breaking strength and is the figure used when calculating whether you have enough securing capacity for your load.
Question 57: At what quantity of explosive (Class 1) goods does a driver require a full ADR certificate?
- Explosives are exempt from ADR if carried by licensed operators
- Above the relevant threshold (which varies by Division and Compatibility Group) — below the threshold, limited exemptions apply (Correct answer)
- All explosives require ADR regardless of quantity
- Only when carrying more than 1 tonne
Correct answer: Above the relevant threshold (which varies by Division and Compatibility Group) — below the threshold, limited exemptions apply
ADR specifies threshold quantities for each class, above which a full ADR certificate is required. For explosives, the thresholds are very low due to their extreme danger. Drivers must check the specific tables in ADR Chapter 1.1.3.6 for their substance.
Question 58: What is 'IMDG' and how does it relate to ADR?
- The Irish and Maritime Dangerous Goods extension of ADR
- An EU directive expanding ADR requirements
- International Maritime Dangerous Goods code — similar to ADR but for sea transport, using the same UN classification system (Correct answer)
- A type of ADR training certificate
Correct answer: International Maritime Dangerous Goods code — similar to ADR but for sea transport, using the same UN classification system
IMDG (International Maritime Dangerous Goods) is the international code for transporting dangerous goods by sea. Like ADR for road and RID for rail, it uses the same UN numbering system, making cross-modal transport more consistent.
Question 59: At a toucan crossing, which combination of road users may cross?
- Pedestrians and cyclists (Correct answer)
- Pedestrians only
- Pedestrians and horses
- Cyclists and motorcyclists
Correct answer: Pedestrians and cyclists
A toucan crossing (two can cross) is designed for both pedestrians and cyclists to use simultaneously. LGV drivers must give way to both when they have the signal to cross.
Question 60: When must a digital tachograph card be inserted?
- Before the vehicle is driven (Correct answer)
- At the start of the working day
- When driving on motorways only
- Only when driving over 50 km
Correct answer: Before the vehicle is driven
A driver must insert their digital tachograph card before driving begins. Driving without an inserted card is an offence, even for very short distances.
Question 61: Which vehicles are subject to EU drivers' hours rules in the UK?
- All vehicles including cars
- Only articulated vehicles
- Only vehicles over 44 tonnes
- Vehicles over 3.5 tonnes GVW used for carriage of goods, and vehicles carrying more than 9 passengers (Correct answer)
Correct answer: Vehicles over 3.5 tonnes GVW used for carriage of goods, and vehicles carrying more than 9 passengers
EU drivers' hours rules (retained in UK law) apply to vehicles over 3.5 tonnes GVW used for the carriage of goods and vehicles designed to carry more than 9 passengers (including the driver). Some exemptions exist for specific vehicle types and operations.
Question 62: What is the purpose of the annual vehicle test (MOT) inspection for goods vehicles?
- To verify the vehicle meets minimum roadworthiness standards and legal requirements (Correct answer)
- To check the vehicle meets emissions standards only
- To ensure the vehicle is fit for its payload
- To replace routine maintenance schedules
Correct answer: To verify the vehicle meets minimum roadworthiness standards and legal requirements
The annual test checks that the vehicle meets minimum safety and roadworthiness standards required by law, covering brakes, lights, steering, tyres, structure, and many other items. A pass certificate is required for legal road use.
Question 63: What is the maximum period a driver may have a reduced weekly rest?
- Reduced weekly rest can be taken every week
- A reduced weekly rest of 24 hours may be taken but must be compensated before the end of the third following week (Correct answer)
- Twice per calendar year
- Only once per month
Correct answer: A reduced weekly rest of 24 hours may be taken but must be compensated before the end of the third following week
A driver may take a reduced weekly rest of at least 24 hours instead of the full 45 hours, but the reduction must be compensated by an equivalent block of rest taken en bloc before the end of the third week following the reduced rest.
Question 64: Which of the following vehicles is exempt from EU tachograph rules?
- Vehicles used for the carriage of goods with a maximum authorised mass not exceeding 3.5 tonnes (Correct answer)
- Vehicles used only at night
- Vehicles travelling less than 100 km
- All vehicles used for agricultural purposes
Correct answer: Vehicles used for the carriage of goods with a maximum authorised mass not exceeding 3.5 tonnes
Vehicles with a maximum authorised mass (MAM) of 3.5 tonnes or less are generally exempt from EU tachograph requirements. Many other exemptions also exist for specific vehicle types and operations.
Question 65: In icy conditions, by how much can stopping distances for an LGV increase compared to dry roads?
- Five times
- Three times
- Up to ten times (Correct answer)
- Two times
Correct answer: Up to ten times
In icy conditions, stopping distances can increase by up to ten times compared to dry roads due to the severe loss of tyre grip.
Question 66: What action should an ADR driver take if a dangerous goods container is visibly damaged and leaking?
- Attempt to contain the leak using available materials
- Stop safely, move to a safe distance, call emergency services, give them the transport document and written instructions, and do not attempt to handle the leaking substance (Correct answer)
- Continue driving to the nearest fire station
- Only call emergency services if the leak is a Class 1, 6, or 7 substance
Correct answer: Stop safely, move to a safe distance, call emergency services, give them the transport document and written instructions, and do not attempt to handle the leaking substance
A leaking dangerous goods container is a serious incident. The driver must stop safely, evacuate to a safe distance, call emergency services (999), provide them with the transport document and written instructions, and not attempt to handle or contain the substance without appropriate PPE and training.
Question 67: What does the UN number 1203 on an orange Kemler plate indicate?
- Heating oil
- Petrol (gasoline/motor fuel) (Correct answer)
- Diesel fuel
- Liquid petroleum gas
Correct answer: Petrol (gasoline/motor fuel)
UN 1203 is the UN number for petrol (gasoline/motor fuel). This is one of the most common UN numbers seen on tankers. Understanding common UN numbers helps drivers and emergency services identify substances quickly.
Question 68: What should an LGV driver do if their vehicle breaks down on a motorway?
- Place a warning triangle behind the vehicle in the carriageway
- Move to the hard shoulder if possible, switch on hazard lights, exit via the nearside, call for assistance from the emergency telephone (Correct answer)
- Stop in lane 1 and wait for help
- Continue to the next junction before stopping
Correct answer: Move to the hard shoulder if possible, switch on hazard lights, exit via the nearside, call for assistance from the emergency telephone
On a motorway breakdown, pull onto the hard shoulder if possible, position the vehicle near an emergency telephone, switch on hazard lights, exit the vehicle from the nearside (left side), move to the bank beyond the barrier, and use the roadside emergency telephone.
Question 69: What does a radioactive (Class 7) transport index (TI) number indicate?
- The level of radiation dose rate at 1 metre from the package — used to control accumulation limits in vehicles (Correct answer)
- The driver's permitted exposure time
- The weight of the radioactive package
- The total activity of the radioactive substance
Correct answer: The level of radiation dose rate at 1 metre from the package — used to control accumulation limits in vehicles
The Transport Index (TI) is a number on the label of a radioactive package indicating the maximum radiation dose rate in microsieverts per hour at 1 metre from the surface. TI values are used by carriers to ensure safe accumulation limits are not exceeded.
Question 70: What does a rectangular blue sign with a white lorry symbol indicate on a motorway?
- A lorry restriction zone
- A weigh bridge ahead
- A lorry parking area ahead
- Mandatory route for goods vehicles (Correct answer)
Correct answer: Mandatory route for goods vehicles
Rectangular blue signs with a white lorry symbol indicate a mandatory route that goods vehicles must follow, often directing HGVs away from unsuitable roads.
Question 71: Can a driver use a ferry crossing as a rest period?
- No, ferry crossings never count as rest
- Yes, if it lasts at least one hour and a suitable sleeping facility is available (Correct answer)
- Yes, any ferry crossing counts as rest regardless of duration
- Only if the driver is off the vehicle
Correct answer: Yes, if it lasts at least one hour and a suitable sleeping facility is available
A driver can take their regular or reduced daily rest on a ferry or train if the crossing is at least one hour, a suitable bunk or couchette is available, and it is used for sleeping.
Question 72: What is the recommended technique for an LGV driver dealing with high crosswinds on a motorway bridge?
- Accelerate to maintain momentum through the exposed section
- Steer into the wind to counter it
- Reduce speed, hold the steering wheel firmly, and be prepared for a sudden gust on leaving the bridge (Correct answer)
- Stop before the bridge and wait for wind to reduce
Correct answer: Reduce speed, hold the steering wheel firmly, and be prepared for a sudden gust on leaving the bridge
Bridges and exposed sections experience stronger crosswinds. LGV drivers should reduce speed before the exposed section, grip the wheel firmly, and be particularly aware of the sudden gust effect when leaving a sheltered area (like entering or exiting a cutting).
Question 73: What is the 'drawbar weight' limit relevant to when operating a lorry and drawbar trailer combination?
- The combined gross weight of the lorry plus trailer — typically up to 44 tonnes for five axles or more (Correct answer)
- The maximum towing capacity of the engine
- Only the weight of the drawbar trailer itself
- The weight limit for the hitch coupling mechanism only
Correct answer: The combined gross weight of the lorry plus trailer — typically up to 44 tonnes for five axles or more
A drawbar combination (rigid lorry towing a trailer) is subject to combined gross weight limits depending on axle count. The combination must not exceed its train weight limit, which varies by configuration.
Question 74: What are 'written instructions' (Tremcards) that must be carried in ADR vehicle cabs?
- Load securing instructions for hazardous cargo
- The driver's medical certificate
- Emergency response instructions in the driver's language describing the substance's hazards and actions to take in an emergency (Correct answer)
- The vehicle maintenance log
Correct answer: Emergency response instructions in the driver's language describing the substance's hazards and actions to take in an emergency
Written instructions (formerly called Tremcards) must be in the vehicle cab, available in languages that the driver understands. They describe the hazards of the substance, protective measures, and actions to take in the event of an accident or emergency.
Question 75: What is the maximum gross weight for a standard two-axle rigid goods vehicle?
- 24 tonnes
- 32 tonnes
- 26 tonnes
- 18 tonnes (Correct answer)
Correct answer: 18 tonnes
A standard two-axle rigid goods vehicle has a maximum gross weight of 18 tonnes in the UK. Exceeding this limit is an offence and can cause road damage and safety hazards.
Question 76: Which authority enforces ADR compliance in Great Britain?
- The Environment Agency
- The Health and Safety Executive (HSE) exclusively
- Trading Standards
- DVSA (Driver and Vehicle Standards Agency) (Correct answer)
Correct answer: DVSA (Driver and Vehicle Standards Agency)
DVSA enforces ADR compliance for road transport in Great Britain. DVSA examiners can check driver certificates, transport documents, vehicle markings, and equipment at the roadside. The HSE and local authorities may also have enforcement roles for storage and workplace aspects.
Question 77: What is the maximum permitted length of an articulated vehicle in the UK?
- 12.0 metres
- 16.5 metres (Correct answer)
- 25.0 metres
- 18.75 metres
Correct answer: 16.5 metres
The maximum overall length for an articulated vehicle (tractor and semi-trailer) is 16.5 metres. A drawbar combination (rigid vehicle and trailer) can be up to 18.75 metres.
Question 78: What is the maximum overall height for vehicles in the UK?
- 4.0 metres
- 4.5 metres
- 5.0 metres
- There is no legal maximum height (Correct answer)
Correct answer: There is no legal maximum height
There is no legal maximum height for vehicles in the UK. However, many bridges have height restrictions, and drivers must know their vehicle's height to avoid bridge strikes. The recommended maximum for safe passage under most bridges is 4.95 metres (16'3").
Question 79: Which combination of conditions is most likely to cause aquaplaning in an LGV?
- Braking gently on a damp road surface
- Driving at speed on a road with standing water (Correct answer)
- Using cruise control in light drizzle
- Driving slowly on a road with heavy rain
Correct answer: Driving at speed on a road with standing water
Aquaplaning occurs when a vehicle travels too fast over standing water, causing the tyres to ride on a film of water and lose contact with the road surface.
Question 80: At 40 mph, how far does a vehicle travel during a 1-second reaction time?
- Approximately 18 metres (Correct answer)
- Approximately 30 metres
- Approximately 24 metres
- Approximately 11 metres
Correct answer: Approximately 18 metres
At 40 mph, a vehicle travels approximately 17.9 metres per second (40 mph ≈ 17.9 m/s). During a 1-second reaction time, the vehicle travels approximately 18 metres before braking begins.
Question 81: What is a 'developing hazard' in the theory test context?
- A permanent road feature like a junction
- A hazard that is being built by construction workers
- A hazard that has already passed
- A situation that is changing and may require the driver to take action, such as a pedestrian approaching the kerb (Correct answer)
Correct answer: A situation that is changing and may require the driver to take action, such as a pedestrian approaching the kerb
A developing hazard is a situation that is actively changing and becoming more dangerous, requiring the driver to respond. Examples include a child running towards the road, a vehicle starting to pull out, or a cyclist wobbling near a junction.
Question 82: What documentation must an ADR driver carry in the vehicle cab?
- Only the transport document
- ADR certificate and driving licence only
- ADR driver training certificate, transport document, written instructions, and vehicle approval certificate (where required) (Correct answer)
- Transport document and insurance certificate
Correct answer: ADR driver training certificate, transport document, written instructions, and vehicle approval certificate (where required)
The full set of ADR cab documentation includes: the driver's ADR training certificate, the transport document (consignment note), written instructions for the substances carried, and (for tank vehicles) the vehicle's ADR approval certificate.
Question 83: What is the Working Time Directive's maximum average weekly working time for mobile workers?
- 40 hours
- 35 hours
- 48 hours (Correct answer)
- 60 hours
Correct answer: 48 hours
The Road Transport Working Time Directive limits average weekly working time for mobile workers to 48 hours, averaged over a reference period of 17 weeks (extendable to 26 weeks by agreement). Working time cannot exceed 60 hours in any single week.
Question 84: What are the penalties for drivers' hours offences in the UK?
- A verbal warning only
- A letter to the driver's employer
- Fixed penalties of up to £300 per offence, with more serious cases resulting in prosecution, unlimited fines, and possible imprisonment (Correct answer)
- No penalties — the rules are advisory
Correct answer: Fixed penalties of up to £300 per offence, with more serious cases resulting in prosecution, unlimited fines, and possible imprisonment
DVSA can issue fixed penalties of up to £300 per offence. Serious or persistent offences can lead to prosecution in court with unlimited fines and potential imprisonment. The driver's licence can also be affected, and the operator's OCRS score worsened.
Question 85: What is 'rear cut-in' and why is it a hazard perception issue for LGV drivers?
- When someone cuts in behind your vehicle
- When the rear of a long vehicle tracks inside the front wheels' path on turns, potentially hitting cyclists or kerbs (Correct answer)
- When the rear doors open during transit
- When the rear of the trailer is damaged
Correct answer: When the rear of a long vehicle tracks inside the front wheels' path on turns, potentially hitting cyclists or kerbs
Rear cut-in occurs when the rear of a long vehicle follows a tighter path than the front wheels during turns. This can sweep cyclists off the road, mount kerbs, or collide with bollards and pedestrians. It is one of the most dangerous aspects of LGV manoeuvring.
Question 86: What does 'ADR' stand for in relation to dangerous goods transport?
- Accord Dangereux Routier — the European agreement on international carriage of dangerous goods by road (Correct answer)
- Advanced Dangerous Regulations
- Authorised Dangerous Road transport agreement
- Approved Driver Requirements
Correct answer: Accord Dangereux Routier — the European agreement on international carriage of dangerous goods by road
ADR stands for Accord Dangereux Routier (European Agreement concerning the International Carriage of Dangerous Goods by Road). It is a UN-based international treaty setting out rules for transporting dangerous goods by road.
Question 87: How often must an operator download data from a digital tachograph vehicle unit?
- At least every 120 days
- At least every 56 days
- At least every 90 days (Correct answer)
- At least every 28 days
Correct answer: At least every 90 days
Operators must download data from the vehicle unit at least every 90 days. Driver card data must be downloaded at least every 28 days.
Question 88: What is anti-compound on a braking system?
- A cleaning fluid for brake components
- An anti-rust coating on brake drums
- A type of brake pad material
- A mechanism that prevents the service brake and spring brake from being applied simultaneously on the same wheel (Correct answer)
Correct answer: A mechanism that prevents the service brake and spring brake from being applied simultaneously on the same wheel
Anti-compound prevents the simultaneous application of both the service brake and spring brake on the same wheel, which could generate excessive force and damage brake components. When the parking brake is applied, the anti-compound device releases the service brake pressure.
Question 89: What is the daily duty time limit under GB domestic drivers' hours rules?
- 16 hours
- No specific daily duty limit applies (Correct answer)
- 9 hours
- 11 hours
Correct answer: No specific daily duty limit applies
Under GB domestic rules, there is no specific daily duty time limit. However, drivers must not work more than 11 hours in a day and must take a daily rest period. The Working Time Directive also limits average weekly working time to 48 hours.
Question 90: What class are infectious substances assigned to in ADR?
- Class 6.2 (Correct answer)
- Class 7
- Class 4.3
- Class 6.1
Correct answer: Class 6.2
Infectious substances (substances containing microorganisms known or reasonably expected to cause infectious disease in humans or animals) are Class 6.2 under ADR. Class 6.1 covers toxic substances. Medical or clinical waste carrying infectious risk is also Class 6.2.
Question 91: What is a 'split daily rest' and how must it be taken?
- Split into two equal parts of 5.5 hours each
- Split into two periods: first at least 3 hours, then at least 9 hours (Correct answer)
- Three periods totalling 11 hours
- Any two periods totalling 11 hours
Correct answer: Split into two periods: first at least 3 hours, then at least 9 hours
A split daily rest must be taken in two periods: the first must be at least 3 uninterrupted hours and the second must be at least 9 uninterrupted hours, taken in that order.
Question 92: When driving an LGV past a row of parked vehicles, what hazard should you be particularly aware of?
- Only oncoming traffic
- The parked vehicles blocking your satellite navigation signal
- Pedestrians (especially children) stepping out from between parked vehicles, and vehicle doors opening (Correct answer)
- The parked vehicles may start flying
Correct answer: Pedestrians (especially children) stepping out from between parked vehicles, and vehicle doors opening
Parked vehicles create blind spots from which pedestrians, particularly children, may step out unexpectedly. Vehicle doors may also open into your path. LGV drivers should reduce speed, increase the gap from parked vehicles, and be ready to stop.
Question 93: Which lanes of a three-lane motorway are LGVs over 7.5 tonnes permitted to use?
- All three lanes
- Lanes 1 and 3 only
- Lane 1 only
- Lanes 1 and 2 only (Correct answer)
Correct answer: Lanes 1 and 2 only
LGVs exceeding 7.5 tonnes are prohibited from using lane 3 (the outside lane) on motorways with three or more lanes. They may travel in lanes 1 and 2, and must return to lane 1 when not overtaking.
Question 94: How does driving with a fully loaded trailer affect the stopping characteristics compared to the tractor unit alone?
- A fully loaded trailer actually improves stopping by increasing rear traction
- Only the tractor unit's brakes matter — trailer brakes are supplementary
- The combination has greater mass and momentum, significantly increasing stopping distance and requiring anticipatory braking (Correct answer)
- The trailer brakes compensate, making stopping similar to the tractor alone
Correct answer: The combination has greater mass and momentum, significantly increasing stopping distance and requiring anticipatory braking
A fully loaded articulated combination has vastly more mass than the tractor alone. The increase in kinetic energy means stopping distances are proportionally much longer. Both tractor and trailer brakes are needed, and brake balance (EBS) is critical to prevent jack-knife.
Question 95: Under GB domestic drivers' hours rules, what is the maximum daily driving time?
- 10 hours (Correct answer)
- 8 hours
- 9 hours
- 12 hours
Correct answer: 10 hours
Under GB domestic drivers' hours rules (which apply to certain exempt vehicles not covered by EU rules), the maximum daily driving time is 10 hours.
Question 96: What is the purpose of the trailer emergency line (red coupling)?
- To supply air for the trailer air suspension
- To provide heating to the trailer
- To automatically apply the trailer brakes if the trailer separates from the tractor unit (Correct answer)
- To supply electrical power to the trailer
Correct answer: To automatically apply the trailer brakes if the trailer separates from the tractor unit
The emergency line (red coupling head) maintains air pressure in the trailer's emergency relay valve. If the trailer separates from the tractor, this line loses pressure, causing the emergency relay valve to apply the trailer brakes automatically, bringing the trailer to a halt.
Question 97: Before starting a journey, what fluid level must an LGV driver check under a daily walkaround check?
- Engine oil only
- Coolant and brake fluid only
- Fuel and oil only
- Engine oil, coolant, brake fluid, power steering fluid and screenwash (Correct answer)
Correct answer: Engine oil, coolant, brake fluid, power steering fluid and screenwash
A thorough daily walkaround check includes checking all fluid levels: engine oil, coolant, brake fluid, power steering fluid, and screenwash. Low levels can cause mechanical failure on the road.
Question 98: What is the meaning of a red circle sign with a white background and a number inside?
- Minimum speed limit
- Speed advisory for lorries only
- Recommended speed
- Maximum speed limit (Correct answer)
Correct answer: Maximum speed limit
A red circle with a white background and a number is a maximum speed limit sign. All vehicles must not exceed the speed shown, and LGVs may have lower limits regardless.
Question 99: What is the 'excepted quantity' (EQ) concept in ADR?
- A quantity exemption for vehicles over 7.5 tonnes only
- Quantities above which a full ADR certificate is required
- Very small quantities of certain dangerous goods exempt from most ADR requirements — even smaller than limited quantities (Correct answer)
- Quantities exempt from carriage document requirements only
Correct answer: Very small quantities of certain dangerous goods exempt from most ADR requirements — even smaller than limited quantities
Excepted Quantities allow tiny amounts of certain dangerous goods (typically milligrams to a few millilitres per package) to be transported with minimal ADR requirements. They are indicated by a diamond mark with 'E' followed by a number on the package.
Question 100: What is the maximum weekly driving time under EU rules?
- 56 hours (Correct answer)
- 48 hours
- 60 hours
- 50 hours
Correct answer: 56 hours
The maximum driving time in any single week is 56 hours under EU Regulation 561/2006. However, the fortnightly limit of 90 hours also applies.
UK LGV Theory Test (Driver CPC Part 1)
The UK Large Goods Vehicle (LGV) theory test is the multiple-choice component of Driver CPC Part 1, assessing knowledge of the Highway Code, road safety, tachograph rules, drivers' hours, vehicle loading, dangerous goods, and LGV-specific regulations required to drive lorries professionally in Great Britain.
