UK Driver CPC Part 1 Theory Test — Questions and Answers

Question 1: Under EU cabotage rules retained in UK law, what restrictions apply to foreign hauliers operating within the UK?

Foreign hauliers may carry out up to 2 cabotage operations within 7 days of the last unloading of an international load (Correct answer)
Foreign hauliers are banned from UK roads
Foreign hauliers may operate for up to 1 year without restriction
No restrictions apply

Correct answer: Foreign hauliers may carry out up to 2 cabotage operations within 7 days of the last unloading of an international load

Foreign hauliers entering the UK with an international load may carry out up to 2 cabotage operations within 7 days of the last unloading of the international incoming load. These rules prevent permanent market access without a UK operator licence.

Question 2: What is the safest action to take if you feel drowsy while driving a commercial vehicle?

Pull over safely at the earliest opportunity and rest (Correct answer)
Reduce your speed and drive slowly to your destination
Drink a caffeinated drink at the next services and continue
Open the window and turn up the radio to stay alert

Correct answer: Pull over safely at the earliest opportunity and rest

Stopping and resting is the only safe response to driver drowsiness, as no other measure reliably restores the level of alertness required for safe driving.

Question 3: What is the professional driver's responsibility regarding mobile phone use while driving?

Using a phone is only illegal on motorways
Using a handheld mobile phone while driving is illegal and can result in 6 penalty points and a £200 fine (Correct answer)
They can use a handheld phone on quiet roads
Hands-free phones are also illegal for professional drivers

Correct answer: Using a handheld mobile phone while driving is illegal and can result in 6 penalty points and a £200 fine

Using a handheld mobile phone while driving is illegal under UK law, resulting in 6 penalty points and a £200 fine. For professional drivers, this is particularly serious as 6 points within the first 2 years of holding a licence results in automatic disqualification.

Question 4: What is the purpose of the differential in an HGV drivetrain?

To change the engine's fuel supply
To provide additional braking force
To allow the driven wheels to rotate at different speeds when cornering (Correct answer)
To connect the trailer to the tractor unit

Correct answer: To allow the driven wheels to rotate at different speeds when cornering

The differential allows the driven wheels on the same axle to rotate at different speeds during cornering. The outer wheel travels a greater distance than the inner wheel, so must rotate faster. Without a differential, the tyres would scrub and handling would be dangerous.

Question 5: When loading palletised goods, what should the driver check?

Whether the pallets are made of wood or plastic
Only the colour of the shrink wrap
Only the number of pallets
That pallets are in good condition, loads are properly stacked and wrapped, and the total weight is within limits (Correct answer)

Correct answer: That pallets are in good condition, loads are properly stacked and wrapped, and the total weight is within limits

The driver should check that pallets are undamaged and structurally sound, goods are properly stacked (not overhanging), shrink wrap is intact and adequate, the load plan distributes weight correctly, and the total weight including pallets is within legal limits.

Question 6: What type of braking system do most modern HGVs use?

Electric brakes only
Cable-operated brakes
Air-operated (pneumatic) disc or drum brakes (Correct answer)
Hydraulic brakes only

Correct answer: Air-operated (pneumatic) disc or drum brakes

Most modern HGVs use air-operated (pneumatic) braking systems with disc or drum brakes. Compressed air operates the brake chambers, which push the brake pads against the disc or drums against the shoes. Air brakes are preferred because they are fail-safe.

Question 7: What is the AETR agreement and when does it apply?

An agreement about road construction standards
A trade agreement for vehicle exports
The European Agreement on International Road Transport covering drivers' hours for journeys through non-EU countries (Correct answer)
An agreement about vehicle emissions

Correct answer: The European Agreement on International Road Transport covering drivers' hours for journeys through non-EU countries

The AETR (Accord Européen sur les Transports Routiers) agreement applies to international journeys through countries that are not EU member states. It contains similar drivers' hours rules to EU Regulation 561/2006.

Question 8: What should a professional driver do if they witness a road traffic collision?

Stop safely, ensure scene safety, call 999, and provide what assistance they can (Correct answer)
Take a video and post it on social media
Drive past as it is not their responsibility
Only stop if their vehicle is involved

Correct answer: Stop safely, ensure scene safety, call 999, and provide what assistance they can

Professional drivers should stop safely if they can assist without creating additional hazards. They should ensure scene safety, call 999, provide first aid if trained, and act as a witness. Their professional skills and first aid training can be invaluable at collision scenes.

Question 9: What is the purpose of load restraint calculations?

To calculate the price of the goods
To determine the force required to prevent the load from moving during braking, acceleration, and cornering (Correct answer)
To calculate fuel consumption
To determine the number of delivery stops

Correct answer: To determine the force required to prevent the load from moving during braking, acceleration, and cornering

Load restraint calculations determine the forces that will act on a load during transport (particularly during emergency braking) and ensure sufficient restraint is in place. The standard requirement is that restraint must withstand forces equal to the total weight of the load forward.

Question 10: What is the purpose of the EU Driver CPC Directive (2003/59/EC) as retained in UK law?

To set vehicle emission standards
To ensure professional drivers maintain and update their driving knowledge and skills through periodic training (Correct answer)
To standardise vehicle registration plates
To regulate fuel prices across Europe

Correct answer: To ensure professional drivers maintain and update their driving knowledge and skills through periodic training

The Driver CPC Directive ensures professional LGV and PCV drivers undergo initial qualification and then complete 35 hours of periodic training every 5 years. This maintains and updates their professional competence in areas including road safety, health, and regulations.

Question 11: Why must you avoid overtaking another vehicle on a left-hand bend?

It is only prohibited in wet weather conditions
It is only prohibited when carrying a full load
Your view ahead is restricted by the bend, hiding oncoming traffic (Correct answer)
It is only prohibited at night or in poor visibility

Correct answer: Your view ahead is restricted by the bend, hiding oncoming traffic

On a left-hand bend, the curve blocks your view of oncoming traffic, making it impossible to judge whether it is safe to overtake.

Question 12: Which lights should be switched on when driving in conditions where visibility is reduced but above 100 metres?

Dipped headlights (Correct answer)
Side lights only
Hazard warning lights
Full beam headlights

Correct answer: Dipped headlights

Dipped headlights must be used whenever visibility is reduced to ensure the vehicle is seen by other road users without dazzling them.

Question 13: Why should unnecessary electrical loads be switched off to save fuel?

Electrical systems use a separate battery that does not affect fuel
Electrical systems do not use fuel
Only the headlights affect fuel consumption
The alternator requires engine power to generate electricity — more electrical load means more fuel consumption (Correct answer)

Correct answer: The alternator requires engine power to generate electricity — more electrical load means more fuel consumption

Every electrical system in the vehicle is ultimately powered by the engine via the alternator. Running unnecessary electrical loads (air conditioning, heated screens, extra lights) increases the load on the alternator, which requires more engine power and therefore more fuel.

Question 14: What is a 'split daily rest' under the retained EU regulations?

Sleeping in two different locations
Taking rest every other day instead of daily
Taking the daily rest in two periods: the first at least 3 hours and the second at least 9 hours (totalling 12 hours) (Correct answer)
Any rest period split by a phone call

Correct answer: Taking the daily rest in two periods: the first at least 3 hours and the second at least 9 hours (totalling 12 hours)

A split daily rest allows the driver to take daily rest in two periods within a 24-hour period. The first must be at least 3 hours and the second at least 9 hours, making a total of 12 hours (one hour more than the regular 11-hour rest).

Question 15: What does the ABS (Anti-lock Braking System) do on an HGV?

It reduces brake wear during normal driving
It automatically applies the brakes when an obstacle is detected
It prevents the wheels from locking during heavy braking, allowing the driver to maintain steering control (Correct answer)
It stops the vehicle faster in all conditions

Correct answer: It prevents the wheels from locking during heavy braking, allowing the driver to maintain steering control

ABS prevents wheel lock-up during heavy braking by rapidly modulating brake pressure to individual wheels. This maintains tyre grip and allows the driver to continue steering the vehicle while braking, reducing the risk of jackknifing and skidding.

Question 16: How should you treat a suspected broken bone (fracture)?

Try to straighten the limb
Immobilise the injury by supporting it in the position found, apply a cold pack, and seek medical help (Correct answer)
Massage the area to reduce swelling
Get the casualty to move the limb to test if it is broken

Correct answer: Immobilise the injury by supporting it in the position found, apply a cold pack, and seek medical help

Do not attempt to straighten or move the injured limb. Support and immobilise it in the position found using padding, slings, or splints if available. Apply a cold pack wrapped in cloth to reduce swelling, and arrange for medical attention.

Question 17: What is the most fuel-efficient way to accelerate in an HGV?

Accelerate smoothly and progressively, using the green band on the rev counter (Correct answer)
Use the lowest gear and highest revs
Alternate between accelerating and coasting
Accelerate as quickly as possible to reach cruising speed

Correct answer: Accelerate smoothly and progressively, using the green band on the rev counter

Smooth, progressive acceleration within the green band (typically 1,000-1,500 rpm) is the most fuel-efficient approach. Aggressive acceleration wastes fuel and increases wear. Block gear changing (skipping gears) can also help when appropriate.

Question 18: How does correct use of the vehicle's telematics system help with eco-driving?

Telematics only tracks vehicle location
Telematics cannot help with fuel efficiency
Only managers can use telematics data
Telematics provides real-time feedback on driving style and identifies areas for improvement in fuel efficiency (Correct answer)

Correct answer: Telematics provides real-time feedback on driving style and identifies areas for improvement in fuel efficiency

Modern telematics systems provide real-time data on driving style including harsh braking events, excessive idling, over-revving, and fuel consumption. This feedback helps drivers identify and correct fuel-wasting behaviours. Many systems also provide fuel-efficiency scores.

Question 19: Under the Highway Code, when should rear fog lights be used?

Whenever it is raining heavily
At night on any unlit road
When visibility falls below 200 metres
When visibility falls below 100 metres (Correct answer)

Correct answer: When visibility falls below 100 metres

Rear fog lights must only be used when visibility drops below 100 metres, as using them unnecessarily can dazzle following drivers.

Question 20: What significant danger does a strong crosswind pose to a high-sided vehicle?

It has no measurable effect at normal road speeds
It can push the vehicle sideways causing instability or rollover (Correct answer)
It only affects empty vehicles travelling above 50 mph
It improves fuel economy by reducing engine load

Correct answer: It can push the vehicle sideways causing instability or rollover

High-sided vehicles present a large surface area to the wind, making them vulnerable to sudden lateral forces that can cause instability or rollover.

Question 21: How does vehicle weight affect fuel consumption?

Weight has no effect on modern vehicles
Heavier vehicles are more fuel-efficient due to momentum
Only the trailer weight matters, not the tractor
Every additional tonne increases fuel consumption — reducing unnecessary weight improves economy (Correct answer)

Correct answer: Every additional tonne increases fuel consumption — reducing unnecessary weight improves economy

Every additional tonne of vehicle weight increases fuel consumption, particularly during acceleration and hill climbing. Drivers should ensure unnecessary items are not carried, trailers are not overloaded, and empty return trips are avoided where possible.

Question 22: Why is it important to distribute a load evenly across the trailer floor?

To make unloading faster
Even distribution is not important if the load is secured
To ensure axle weights are within legal limits and the vehicle handles safely (Correct answer)
For aesthetic reasons only

Correct answer: To ensure axle weights are within legal limits and the vehicle handles safely

Uneven load distribution can cause individual axle weights to exceed legal limits, affect vehicle stability and steering, increase the risk of rollover on corners, and cause uneven tyre and brake wear. The load plan should ensure weight is spread appropriately.

Question 23: Why should a driver report near-miss incidents to their employer?

Near-misses do not need reporting
Near-miss reports help identify and prevent potential future accidents before they cause harm (Correct answer)
Reporting near-misses will result in the driver being disciplined
Near-misses are only reported to the police

Correct answer: Near-miss reports help identify and prevent potential future accidents before they cause harm

Near-miss reporting is a valuable safety tool. Analysing near-misses can identify patterns, hazards, and system failures before they cause actual harm. A strong near-miss reporting culture helps prevent serious incidents and demonstrates professional commitment to safety.

Question 24: What are the signs that a casualty may be going into shock?

High temperature and sweating
Loud aggressive behaviour
Red face and slow pulse
Pale, cold, clammy skin, rapid weak pulse, and rapid shallow breathing (Correct answer)

Correct answer: Pale, cold, clammy skin, rapid weak pulse, and rapid shallow breathing

Signs of shock include pale, cold, and clammy skin; a rapid but weak pulse; rapid shallow breathing; nausea; dizziness; and confusion. Shock can be life-threatening and requires the casualty to lie down with legs elevated (unless contraindicated).

Question 25: What is the importance of accurate record-keeping for a professional driver?

Records are only needed for tax purposes
Accurate records protect the driver legally, ensure regulatory compliance, and support the operator's licence (Correct answer)
Records are not important in modern logistics
Only the office needs to keep records

Correct answer: Accurate records protect the driver legally, ensure regulatory compliance, and support the operator's licence

Professional drivers must maintain accurate records including tachograph data, defect reports, delivery documentation, and fuel records. These records protect the driver in legal disputes, demonstrate compliance with regulations, and are essential for the operator's licence compliance.

Question 26: What is the purpose of dunnage bags (air bags) in load security?

To cushion fragile items from vibration
To provide additional suspension to the vehicle
To keep the load warm
To fill voids between items in the load to prevent movement (Correct answer)

Correct answer: To fill voids between items in the load to prevent movement

Dunnage bags (inflatable air bags) are placed in voids between items in a load to prevent lateral and longitudinal movement. They expand to fill gaps and provide bracing. They are commonly used in containerised and palletised loads.

Question 27: Under the retained EU rules, what is the maximum fortnightly (two-week) driving time?

112 hours
90 hours (Correct answer)
80 hours
100 hours

Correct answer: 90 hours

The maximum driving time over any two consecutive weeks is 90 hours. Combined with the weekly limit of 56 hours, this means if a driver drives 56 hours in one week, they can only drive 34 hours in the next.

Question 28: When is a large vehicle most likely to create a dangerous bow wave affecting pedestrians and cyclists?

When travelling at speed through standing water (Correct answer)
When braking heavily in rain
When stationary at the kerb
When travelling uphill slowly

Correct answer: When travelling at speed through standing water

At speed, a large vehicle displaces water violently outward, creating a bow wave that can drench and destabilise vulnerable road users nearby.

Question 29: What is the maximum speed limit for an HGV over 7.5 tonnes on a single carriageway road in the UK?

50 mph (Correct answer)
40 mph
60 mph
70 mph

Correct answer: 50 mph

Goods vehicles over 7.5 tonnes are legally limited to 50 mph on single carriageway roads.

Question 30: What is the driver's responsibility regarding the security of their vehicle and load?

The load is the customer's responsibility once it leaves their premises
Drivers must take reasonable steps to secure their vehicle and load, especially at rest stops and overnight parks (Correct answer)
Security is the responsibility of the police only
Security measures are only needed for high-value loads

Correct answer: Drivers must take reasonable steps to secure their vehicle and load, especially at rest stops and overnight parks

Drivers must take reasonable steps to secure their vehicle and load at all times, including locking the cab, using anti-theft devices, parking in secure locations, being alert for suspicious activity, and never leaving the vehicle unattended with the engine running.

Question 31: What does DR ABC stand for in first aid?

Directions, Route, Arrive, Begin, Complete
Drive, Reverse, Accelerate, Brake, Clutch
Dial, Report, Assess, Bandage, Cover
Danger, Response, Airway, Breathing, Circulation (Correct answer)

Correct answer: Danger, Response, Airway, Breathing, Circulation

DR ABC is the primary assessment sequence: check for Danger, check for Response (is the casualty conscious?), open the Airway (head tilt, chin lift), check for Breathing, and check Circulation. This systematic approach ensures nothing is missed.

Question 32: What is Regulation 165/2014 (retained in UK law) primarily about?

Road infrastructure standards
Driver medical requirements
Vehicle emissions standards
Tachograph requirements including digital tachograph specifications and workshop approval (Correct answer)

Correct answer: Tachograph requirements including digital tachograph specifications and workshop approval

Regulation 165/2014 sets out the requirements for tachographs, including specifications for digital tachographs, driver cards, company cards, workshop cards, and control cards. It also covers tachograph workshop approvals and inspections.

Question 33: What is the purpose of the EGR (Exhaust Gas Recirculation) system?

To improve fuel economy by reusing fuel
To increase engine power
To reduce exhaust noise levels
To reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gas back into the engine (Correct answer)

Correct answer: To reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gas back into the engine

The EGR system reduces NOx emissions by recirculating a controlled amount of exhaust gas back into the intake manifold. This lowers combustion temperatures, which reduces the formation of nitrogen oxides, a major pollutant.

Question 34: What is the function of the DPF (Diesel Particulate Filter)?

To reduce engine noise
To trap and periodically burn off soot particles from the exhaust, reducing particulate emissions (Correct answer)
To filter the air entering the engine
To filter diesel fuel before injection

Correct answer: To trap and periodically burn off soot particles from the exhaust, reducing particulate emissions

The DPF captures soot particles from the exhaust gas and periodically undergoes 'regeneration' where the trapped soot is burned off at high temperature. This dramatically reduces particulate matter emissions. Drivers should allow regeneration to complete and not interrupt it.

Question 35: What is the correct action when approaching a level crossing where the barriers are already open?

Sound your horn briefly and then proceed
Stop, look both ways, and listen before crossing if safe (Correct answer)
Proceed at normal speed as the barriers confirm it is safe
Wait for the barriers to close and reopen before crossing

Correct answer: Stop, look both ways, and listen before crossing if safe

Open barriers do not guarantee safety — you must always stop, look, and listen at a level crossing before proceeding.

Question 36: What is 'blocking and bracing' in load security?

Using physical barriers and wedges to prevent the load from moving within the vehicle (Correct answer)
A type of ratchet strap
Using the parking brake to hold the load
Blocking the road during loading

Correct answer: Using physical barriers and wedges to prevent the load from moving within the vehicle

Blocking and bracing uses physical items (timber, inflatable dunnage bags, chocks) to fill gaps between the load and the vehicle structure, preventing movement. It works alongside lashing to provide comprehensive load security.

Question 37: What is the minimum legal tyre tread depth for commercial vehicle tyres in the UK?

2.0 mm
1.0 mm
2.5 mm
1.6 mm (Correct answer)

Correct answer: 1.6 mm

UK law requires a minimum tread depth of 1.6 mm across the central three-quarters of the tread width for commercial vehicle tyres.

Question 38: What is an AED (Automated External Defibrillator) and when should it be used?

A device for treating broken bones
A diagnostic tool used only by doctors
A device for checking blood pressure
A device that analyses heart rhythm and delivers a shock if needed, used when someone is in cardiac arrest (Correct answer)

Correct answer: A device that analyses heart rhythm and delivers a shock if needed, used when someone is in cardiac arrest

An AED analyses the heart's rhythm and, if it detects a shockable rhythm (ventricular fibrillation), delivers an electric shock to restore normal heart function. It should be used as soon as possible on anyone in cardiac arrest, alongside CPR.

Question 39: What is the main benefit of an Anti-lock Braking System (ABS) when activated?

It stops the vehicle in the shortest possible distance regardless of conditions
It automatically applies maximum braking force at all four wheels
It prevents wheel lock-up so the driver can steer while braking (Correct answer)
It applies the parking brake to assist in emergency stops

Correct answer: It prevents wheel lock-up so the driver can steer while braking

ABS prevents the wheels from locking during heavy braking, allowing the driver to maintain directional control and steer around obstacles.

Question 40: What does the EBS (Electronic Braking System) provide over standard ABS?

A cheaper braking system
Longer brake pedal travel
Louder brake noise for warning pedestrians
Faster brake response times, automatic load-sensing, and integration with stability control systems (Correct answer)

Correct answer: Faster brake response times, automatic load-sensing, and integration with stability control systems

EBS provides faster brake response (up to 0.3 seconds faster than pneumatic-only systems), automatic load-proportioning, integration with ESC (Electronic Stability Control), and diagnostic capabilities. It uses electronic signals to control pneumatic brake application.

Question 41: What is the most fuel-efficient cruising speed for most HGVs?

As fast as legally possible
It makes no difference what speed you travel at
Below 30 mph at all times
Between 50-56 mph (the speed limiter range), as fuel consumption increases significantly above these speeds (Correct answer)

Correct answer: Between 50-56 mph (the speed limiter range), as fuel consumption increases significantly above these speeds

Most HGVs are most fuel-efficient at steady speeds between 50-56 mph. Above this, aerodynamic drag increases significantly (doubling for every doubling of speed). The speed limiter (56 mph for most UK HGVs) effectively caps the maximum cruising speed.

Question 42: What action constitutes professional misconduct for an HGV driver?

Taking a break during working hours
Reporting a vehicle defect
Falsifying tachograph records, driving while disqualified, or deliberately overloading a vehicle (Correct answer)
Refusing to drive a defective vehicle

Correct answer: Falsifying tachograph records, driving while disqualified, or deliberately overloading a vehicle

Professional misconduct includes falsifying records, driving while disqualified, driving under the influence, deliberately overloading, or any action that deliberately endangers road users. Such conduct can result in criminal prosecution, loss of licence, and imprisonment.

Question 43: How should you treat a casualty who is unconscious but breathing normally?

Leave them on their back and wait for help
Give them water to drink
Sit them upright against a wall
Place them in the recovery position and monitor their breathing (Correct answer)

Correct answer: Place them in the recovery position and monitor their breathing

An unconscious casualty who is breathing normally should be placed in the recovery position (on their side with the airway open). This prevents the tongue from blocking the airway and allows any fluids to drain. Monitor breathing until help arrives.

Question 44: What is the fuel saving potential of good eco-driving techniques?

5-15% reduction in fuel consumption (Correct answer)
Less than 1%
Eco-driving actually increases fuel consumption
50% reduction in fuel consumption

Correct answer: 5-15% reduction in fuel consumption

Consistent application of eco-driving techniques can typically save 5-15% on fuel consumption. For a vehicle doing 100,000 miles per year at 8 mpg, a 10% saving would be approximately 1,250 litres of diesel — a significant cost and environmental benefit.

Question 45: What force must the load restraint system be capable of withstanding in the forward direction?

200% of the load weight
50% of the load weight
The total weight of the load (100%) (Correct answer)
25% of the load weight

Correct answer: The total weight of the load (100%)

The load restraint system must be capable of withstanding a forward force equal to the total weight of the load. Sideways restraint should be 50% and rearward restraint 50%. This accounts for forces generated during emergency braking.

Question 46: How does cruise control help with eco-driving?

It does not help with fuel efficiency
It reduces engine temperature
It automatically changes gears for maximum power
It maintains a constant speed, preventing the driver from unconsciously varying speed, which wastes fuel (Correct answer)

Correct answer: It maintains a constant speed, preventing the driver from unconsciously varying speed, which wastes fuel

Cruise control maintains a steady speed, eliminating the small speed variations that occur during manual throttle control. This consistency reduces fuel consumption. However, it should be disengaged on hilly terrain where the driver can manage speed more efficiently.

Question 47: When manoeuvring a long vehicle around a roundabout, what specific hazard must the driver be aware of?

Loss of satellite navigation accuracy
Reduced fuel economy during the manoeuvre
Aerodynamic drag from other vehicles
Off-tracking, where rear wheels follow a tighter path than the front (Correct answer)

Correct answer: Off-tracking, where rear wheels follow a tighter path than the front

Off-tracking causes the rear wheels of a long vehicle to cut the corner more tightly than the front wheels, risking mounting kerbs or striking vehicles alongside.

Question 48: How should a professional driver deal with road rage from other road users?

Retaliate to teach them a lesson
Speed up to get away from the aggressive driver
Remain calm, avoid eye contact, do not react, and report the incident if necessary (Correct answer)
Block the aggressive driver's path

Correct answer: Remain calm, avoid eye contact, do not react, and report the incident if necessary

Professional drivers should never engage with aggressive road users. Remaining calm, avoiding provocative eye contact, not retaliating with gestures or driving, and if necessary safely stopping and reporting the incident is the correct approach. Reacting could escalate the situation dangerously.

Question 49: What is the correct ratio of chest compressions to rescue breaths in adult CPR?

15 compressions to 1 breath
5 compressions to 1 breath
30 compressions to 2 breaths (Correct answer)
10 compressions to 3 breaths

Correct answer: 30 compressions to 2 breaths

For adult CPR, the ratio is 30 chest compressions to 2 rescue breaths. Compressions should be at a rate of 100-120 per minute, pressing down 5-6 cm on the centre of the chest. If unable or unwilling to give breaths, continuous compressions alone can help.

Question 50: What should a driver do if they notice the load has shifted during a journey?

Speed up to reach the destination faster
Stop safely as soon as possible, check and re-secure the load before continuing (Correct answer)
Continue to the destination and fix it there
Only stop if the load falls off

Correct answer: Stop safely as soon as possible, check and re-secure the load before continuing

If a load shifts during transit, the driver must stop as soon as it is safe to do so. They must check the load, re-secure it properly, and only continue once satisfied the load is safe. Continuing with an insecure load is both dangerous and illegal.

Question 51: What should you NOT do if a casualty in a vehicle collision has a suspected spinal injury?

Keep them still and support their head
Move them unless there is immediate danger to life such as fire (Correct answer)
Call for emergency help
Talk to them reassuringly

Correct answer: Move them unless there is immediate danger to life such as fire

A casualty with a suspected spinal injury should not be moved unless there is an immediate life threat (such as fire or the vehicle being in a dangerous position). Moving them incorrectly could cause permanent paralysis. Support the head and neck in the position found.

Question 52: What is the recommended minimum safe following distance for a large commercial vehicle in good conditions?

A one-second gap at all times
At least a two-second gap, increased significantly in poor conditions (Correct answer)
A fixed two-second gap in all conditions
A four-second gap regardless of conditions

Correct answer: At least a two-second gap, increased significantly in poor conditions

The Highway Code recommends at least a two-second gap in good conditions, but this must be substantially increased in wet, icy, or foggy conditions.

Question 53: What does continuous professional development (CPD) mean for a professional driver?

It only means completing the mandatory 35-hour CPC training
CPD stops once you pass your driving test
It means actively maintaining and improving skills, knowledge, and awareness throughout your career (Correct answer)
It only applies to drivers under 25

Correct answer: It means actively maintaining and improving skills, knowledge, and awareness throughout your career

CPD goes beyond mandatory CPC training. It includes staying current with regulation changes, learning about new vehicle technologies, improving fuel efficiency techniques, updating first aid knowledge, and developing customer service skills throughout your career.

Question 54: What is the consequence of an insecure load falling from a vehicle on a UK road?

A fixed penalty of £30
No consequences as long as nobody is injured
A verbal warning from the police
The driver can face prosecution, an unlimited fine, penalty points, and potential imprisonment if it causes injury (Correct answer)

Correct answer: The driver can face prosecution, an unlimited fine, penalty points, and potential imprisonment if it causes injury

If an insecure load falls from a vehicle, the driver can be prosecuted for using a vehicle in a dangerous condition. Penalties include an unlimited fine, penalty points on the licence, and if someone is injured or killed, imprisonment for dangerous driving or causing death.

Question 55: What is a retarder and what types are used on HGVs?

An auxiliary braking device — types include exhaust brakes, engine brakes (Jake brakes), and electromagnetic retarders (Correct answer)
A speed limiting device
A device to slow trailer loading
A GPS tracking system

Correct answer: An auxiliary braking device — types include exhaust brakes, engine brakes (Jake brakes), and electromagnetic retarders

A retarder is an auxiliary braking system that slows the vehicle without using the service brakes. Types include exhaust brakes (restricting exhaust flow), engine brakes/Jake brakes (using engine compression), and electromagnetic retarders (using magnetic resistance). They preserve service brake life.

Question 56: What happens if a UK driver's CPC qualification expires?

They can continue driving professionally for 6 months
They receive an automatic 1-year extension
Nothing — CPC is optional
They are no longer legally permitted to drive professionally until they complete the required periodic training (Correct answer)

Correct answer: They are no longer legally permitted to drive professionally until they complete the required periodic training

If a driver's CPC expires, they cannot legally drive professionally. Driving commercially without a valid CPC is an offence that can result in a fine of up to £1,000 for the driver and up to £1,000 for the operator who employs them.

Question 57: How does carrying a full load affect the braking distance of a commercial vehicle?

It has no significant effect on braking distance
It decreases braking distance due to increased traction
It only increases braking distance on wet or slippery surfaces
It significantly increases braking distance due to greater momentum (Correct answer)

Correct answer: It significantly increases braking distance due to greater momentum

A fully laden vehicle carries far greater momentum than an empty one, requiring a much longer distance to stop under the same braking force.

Question 58: What is the primary danger when a high-sided vehicle passes under a bridge?

Loss of satellite navigation signal
Striking the structure if the vehicle exceeds the height restriction (Correct answer)
Reduced engine efficiency on approach
Aerodynamic turbulence disrupting stability

Correct answer: Striking the structure if the vehicle exceeds the height restriction

The driver must verify the vehicle's height is within the bridge restriction before passing under it to avoid a serious collision.

Question 59: How can a driver use hills to their advantage for fuel economy?

Drive faster uphill to get it over with
Always maintain the same speed up and down hills
Always use the highest gear on hills
Build momentum before an uphill, allow speed to reduce slightly on the climb, and use gravity on descents (Correct answer)

Correct answer: Build momentum before an uphill, allow speed to reduce slightly on the climb, and use gravity on descents

Eco-driving on hills involves building speed slightly before an incline, allowing speed to drop a little on the climb (rather than using excessive throttle), and using the descent to recover speed with minimal throttle. This uses gravity rather than fighting it.

Question 60: What is the primary risk of a large vehicle driving too close to the nearside kerb in an urban area?

Increased tyre wear on the nearside axles
Reduced fuel economy due to surface friction
Striking pedestrians or cyclists in the nearside blind spot (Correct answer)
Causing excessive damage to the road surface

Correct answer: Striking pedestrians or cyclists in the nearside blind spot

Pedestrians and cyclists in the nearside blind spot can be struck by the vehicle's body or wheels when it passes too close to the kerb.

Question 61: How should you control severe bleeding from a wound?

Apply direct pressure to the wound with a clean dressing and elevate the injured part if possible (Correct answer)
Remove any objects embedded in the wound
Apply a tourniquet as the first response
Wash the wound with cold water

Correct answer: Apply direct pressure to the wound with a clean dressing and elevate the injured part if possible

Apply direct firm pressure to the wound using a sterile dressing or clean cloth. Elevate the injured part above the level of the heart if possible. Do not remove embedded objects. If blood soaks through, apply additional dressings on top.

Question 62: How does anticipating traffic conditions ahead help reduce fuel consumption?

Anticipation is only useful for safety, not fuel saving
It only helps reduce journey time
It does not help with fuel consumption
Reading the road ahead allows the driver to maintain momentum, reduce unnecessary braking and acceleration (Correct answer)

Correct answer: Reading the road ahead allows the driver to maintain momentum, reduce unnecessary braking and acceleration

By looking well ahead and anticipating traffic flow, traffic lights, roundabouts, and hills, drivers can maintain momentum, coast where appropriate, and avoid harsh braking followed by heavy acceleration. This 'smooth driving' approach can save 10-15% on fuel.

Question 63: What is the legal blood alcohol limit for professional HGV drivers in the UK?

Zero — the same limit as car drivers applies, but operators typically enforce zero tolerance (Correct answer)
20mg per 100ml
80mg per 100ml (same as car drivers)
50mg per 100ml

Correct answer: Zero — the same limit as car drivers applies, but operators typically enforce zero tolerance

The legal limit for all drivers in England and Wales is 80mg per 100ml of blood (35mcg per 100ml breath). However, most professional operators enforce a strict zero-tolerance policy, and the consequences of any alcohol for professional drivers are far more severe.

Question 64: How should a load of steel coils be positioned on a flatbed trailer?

Standing upright without any restraint
With the axis of the coil in the direction of travel, using coil wells or chocks, and secured with appropriate chains or straps (Correct answer)
Placed on their side at the front of the trailer
Rolled to the back of the trailer

Correct answer: With the axis of the coil in the direction of travel, using coil wells or chocks, and secured with appropriate chains or straps

Steel coils should be positioned with their axis in the direction of travel (eye-to-the-sky or eye-to-the-front), placed in coil wells or on chocks to prevent rolling, and secured with rated chains or straps. Incorrect loading of coils has caused fatal incidents.

Question 65: How frequently should a professional driver carry out risk assessment while on a journey?

Only during adverse weather or night-time driving
Only before the start of each journey
Only when carrying passengers or hazardous loads
Continuously throughout every journey (Correct answer)

Correct answer: Continuously throughout every journey

Professional drivers must continuously observe, anticipate, and respond to hazards — risk assessment is an ongoing process, not a pre-journey checklist.

Question 66: What is the impact of a professional driver's behaviour on the company's OCRS (Operator Compliance Risk Score)?

OCRS is a voluntary assessment with no consequences
Poor driver conduct (traffic offences, defects, prohibitions) directly worsens the operator's compliance score (Correct answer)
OCRS only measures vehicle maintenance standards
Individual driver behaviour has no effect on OCRS

Correct answer: Poor driver conduct (traffic offences, defects, prohibitions) directly worsens the operator's compliance score

The OCRS is calculated using data from roadside checks, including driver offences, vehicle defects, and prohibitions. Poor driver behaviour directly increases the operator's risk score, making the fleet more likely to be stopped for checks and potentially threatening the operator's licence.

Question 67: By how much can stopping distances increase when driving on ice compared to a dry road?

Five times as far
Twice as far
Three times as far
Up to ten times as far (Correct answer)

Correct answer: Up to ten times as far

On ice, stopping distances can increase by up to ten times compared to a dry road, making reduced speed and increased following distance essential.

Question 68: What is the maximum speed limit for a goods vehicle exceeding 7.5 tonnes on a UK motorway?

55 mph
70 mph
60 mph (Correct answer)
65 mph

Correct answer: 60 mph

UK law restricts goods vehicles over 7.5 tonnes to a maximum of 60 mph on motorways.

Question 69: What is the headboard (front bulkhead) on a flatbed trailer designed to do?

Hold the registration plate
Prevent the load from sliding forward into the cab during emergency braking (Correct answer)
Keep rain off the driver
Provide advertising space

Correct answer: Prevent the load from sliding forward into the cab during emergency braking

The headboard prevents the load from sliding forward into the cab area during heavy braking or a collision. It must be strong enough to withstand the forces generated by the load. Without an adequate headboard, additional forward restraint is essential.

Question 70: What is the function of the air compressor in an HGV?

To power the air conditioning only
To generate compressed air for the braking system, suspension, and other pneumatic systems (Correct answer)
To inflate tyres while driving
To clean the engine air filter

Correct answer: To generate compressed air for the braking system, suspension, and other pneumatic systems

The engine-driven air compressor generates compressed air that is stored in air tanks and used to operate the brakes, air suspension, and other pneumatic systems. Maintaining correct air pressure is critical for brake safety.

Question 71: Why is it important for professional drivers to maintain a clean driving licence?

Points and disqualifications can result in loss of their professional livelihood and CPC qualification (Correct answer)
It is not important as long as the vehicle is insured
Penalty points expire after 1 year
A clean licence only matters when applying for a first job

Correct answer: Points and disqualifications can result in loss of their professional livelihood and CPC qualification

A professional driver's licence is their livelihood. Penalty points, endorsements, or disqualification can result in losing their job, being unable to find alternative employment, and potentially losing their CPC qualification. The consequences are far more severe than for non-professional drivers.

Question 72: Why is it important to check the coolant level regularly on an HGV?

Coolant levels only matter in winter
Coolant only affects the heater
Coolant is purely cosmetic — it colours the radiator fluid
Low coolant can cause the engine to overheat, potentially causing catastrophic engine damage (Correct answer)

Correct answer: Low coolant can cause the engine to overheat, potentially causing catastrophic engine damage

The cooling system prevents the engine from overheating. Low coolant can lead to overheating, which can cause warped cylinder heads, blown head gaskets, seized pistons, or complete engine failure. Coolant also provides frost protection and corrosion inhibition.

Question 73: When calling 999 at a road traffic collision, what information should you provide?

The registration numbers of all vehicles
Only your name
Your location, number of vehicles and casualties, types of injuries, and any hazards such as fuel spills (Correct answer)
Just say 'there has been an accident'

Correct answer: Your location, number of vehicles and casualties, types of injuries, and any hazards such as fuel spills

Provide your exact location (road name, junction, landmarks), the number of vehicles involved, the number and condition of casualties, types of injuries if known, and any hazards such as fuel spills, trapped casualties, or fire risk.

Question 74: If a casualty has an object embedded in a wound, what should you do?

Push the object in further to stop bleeding
Leave it in place, apply pressure around (not on) the object, and build up padding either side (Correct answer)
Pull the object out immediately
Wiggle the object to assess how deep it is

Correct answer: Leave it in place, apply pressure around (not on) the object, and build up padding either side

Never remove an embedded object as it may be stemming blood flow. Apply pressure around the object, build up padding either side to support it, and bandage around it. Removing it could cause catastrophic bleeding.

Question 75: How should a professional driver handle a situation where they are asked to exceed their driving hours?

Comply but document their objection
Exceed the hours but manipulate the tachograph to hide it
Refuse politely, explain the legal restrictions, and contact their transport manager for alternative arrangements (Correct answer)
Comply with the request to keep the customer happy

Correct answer: Refuse politely, explain the legal restrictions, and contact their transport manager for alternative arrangements

A driver must never exceed legal driving hours regardless of pressure from management, customers, or colleagues. They should refuse calmly, cite the specific legal restrictions, and work with their transport manager to find a legal solution such as a relief driver.

Question 76: When using ratchet straps to secure a load, what should you check before use?

That the straps are not damaged, are within date, have readable load ratings, and the ratchet mechanism works correctly (Correct answer)
Only the colour of the strap
That the straps match the vehicle colour
Only that the straps are long enough

Correct answer: That the straps are not damaged, are within date, have readable load ratings, and the ratchet mechanism works correctly

Before use, ratchet straps should be checked for damage (cuts, fraying, UV degradation), that the manufacturer's label is readable with load ratings visible, that the ratchet mechanism operates freely, and that the hooks and fittings are not bent or damaged.

Question 77: What is the safest action when an emergency vehicle with blue lights and sirens approaches from behind on a motorway?

Maintain your current position and speed to avoid sudden movements
Accelerate to create more space ahead of you
Move safely to the left to allow the vehicle to pass without stopping (Correct answer)
Brake sharply and move immediately onto the hard shoulder

Correct answer: Move safely to the left to allow the vehicle to pass without stopping

You should move safely to the left lane to allow the emergency vehicle through, but you must never stop on the motorway itself unless directed to do so.

Question 78: Which EU regulation governing drivers' hours has been retained in UK law post-Brexit?

Regulation 3820/85
Regulation 165/2014
Regulation 561/2006 (Correct answer)
Regulation 1071/2009

Correct answer: Regulation 561/2006

EU Regulation 561/2006 on driving times and rest periods has been retained in UK law post-Brexit. It continues to apply to drivers of vehicles over 3.5 tonnes or carrying more than 9 passengers.

Question 79: What document must UK drivers carry when driving commercially in EU member states?

No documents are required
Only a UK driving licence
A UK driving licence plus a Driver Qualification Card (DQC) (Correct answer)
A passport only

Correct answer: A UK driving licence plus a Driver Qualification Card (DQC)

UK drivers operating in EU member states must carry both their UK driving licence and a valid Driver Qualification Card (DQC), which proves they have completed the required 35 hours of periodic training. Additional documents may include an international driving permit.

Question 80: What is the 5th wheel coupling on an articulated HGV?

The coupling device on the tractor unit that connects to and supports the front of the semi-trailer (Correct answer)
A wheel on the trailer landing gear
A spare wheel mounted on the chassis
The steering wheel

Correct answer: The coupling device on the tractor unit that connects to and supports the front of the semi-trailer

The 5th wheel is a large, greased coupling plate mounted on the tractor unit's chassis. The trailer's kingpin drops into the 5th wheel's jaws, creating a secure but pivoting connection. It carries a significant proportion of the trailer's weight.

Question 81: If you arrive at the scene of a road traffic collision, what should your first priority be?

Direct traffic around the scene
Take photographs for insurance
Move the injured people immediately
Ensure the scene is safe for yourself and others before approaching (Correct answer)

Correct answer: Ensure the scene is safe for yourself and others before approaching

The first priority at any incident scene is to ensure your own safety and that of others. This means assessing hazards (traffic, fuel, fire), switching off vehicle ignitions if safe, using hazard lights and warning triangles, and calling 999 before approaching casualties.

Question 82: Which vehicles are exempt from the EU/UK drivers' hours rules?

Only vehicles under 1 tonne
No vehicles are exempt
Only electric vehicles
Emergency vehicles, military vehicles, and vehicles used by certain public services (Correct answer)

Correct answer: Emergency vehicles, military vehicles, and vehicles used by certain public services

Exemptions include vehicles used by the armed forces, police, fire service, and civil defence. Also exempt are vehicles used for certain agricultural and forestry purposes, and vehicles not exceeding 7.5 tonnes carrying materials or equipment for the driver's own use.

Question 83: What is the function of air suspension on an HGV?

To make the cab more comfortable for the driver only
To increase vehicle speed
To reduce the need for tyres
To provide a smoother ride, protect the load, allow ride height adjustment, and distribute weight more evenly (Correct answer)

Correct answer: To provide a smoother ride, protect the load, allow ride height adjustment, and distribute weight more evenly

Air suspension uses air bags instead of steel springs. Benefits include a smoother ride that protects cargo, the ability to adjust ride height for loading docks, automatic load levelling, and reduced road damage compared to steel suspension.

Question 84: How should you treat a burn from hot liquid or chemicals?

Apply butter or cream immediately
Cool the burn under cool running water for at least 20 minutes, then cover with a sterile dressing or cling film (Correct answer)
Pop any blisters that form
Apply ice directly to the burn

Correct answer: Cool the burn under cool running water for at least 20 minutes, then cover with a sterile dressing or cling film

Burns should be cooled under cool (not ice cold) running water for at least 20 minutes. Remove clothing near the burn (unless stuck to it). Cover with a sterile dressing or clean cling film. Never apply creams, butter, or ice, and do not burst blisters.

Question 85: Why is it important to avoid excessive engine idling from an eco-driving perspective?

An idling engine burns approximately 1-2 litres per hour of fuel while doing no useful work (Correct answer)
Idling has no effect on fuel consumption
Idling is good for the engine
Modern engines do not consume fuel at idle

Correct answer: An idling engine burns approximately 1-2 litres per hour of fuel while doing no useful work

An HGV engine idling typically burns 1-2 litres of diesel per hour while producing no useful work. Over a year, unnecessary idling can waste thousands of litres. Anti-idling technology and driver awareness can significantly reduce this waste.

Question 86: What is the function of the turbocharger in a modern HGV diesel engine?

To cool the engine
To reduce exhaust noise
To filter fuel before injection
To force more air into the engine cylinders, increasing power output and efficiency (Correct answer)

Correct answer: To force more air into the engine cylinders, increasing power output and efficiency

A turbocharger uses exhaust gas energy to spin a turbine that compresses intake air, forcing more air (and therefore more fuel) into the combustion chambers. This increases power output without increasing engine size, also improving fuel efficiency.

Question 87: How many hours of periodic CPC training must a driver complete every 5 years?

50 hours
35 hours (Correct answer)
21 hours
14 hours

Correct answer: 35 hours

Drivers must complete 35 hours of periodic CPC training every 5 years, in blocks of at least 7 hours each. This training must cover the syllabus areas specified in the directive and be delivered by approved training centres.

Question 88: Under the retained EU regulations, what are the requirements for multi-manning (two drivers in the vehicle)?

The first break must be taken within 4.5 hours, but daily rest can be reduced to 9 hours and taken concurrently (Correct answer)
The same rules apply as for single-manning
No breaks are required during multi-manning
Each driver must take a full 11-hour rest separately

Correct answer: The first break must be taken within 4.5 hours, but daily rest can be reduced to 9 hours and taken concurrently

During multi-manning, each driver must take a daily rest of at least 9 hours within a 30-hour period (instead of 24 hours). The first 45 minutes of a co-driver's presence is flexible — they do not need to be in the vehicle for the first hour.

Question 89: What is 'block gear changing' and how does it benefit fuel economy?

Changing gears only when the engine stalls
Using the clutch without pressing the accelerator
Skipping intermediate gears when changing up or down, keeping the engine in its efficient range (Correct answer)
Never changing gear during a journey

Correct answer: Skipping intermediate gears when changing up or down, keeping the engine in its efficient range

Block gear changing means skipping gears (e.g., going from 3rd to 5th or 8th to 5th) rather than changing through every gear sequentially. This keeps the engine in its most efficient rev range and reduces the time spent at inefficient RPMs during gear changes.

Question 90: What does a flashing amber beacon on a slow-moving vehicle on the road indicate?

The vehicle is reversing towards the roadway
The vehicle is breaking down and needs assistance
The vehicle is wide, slow, or requires extra caution from passing drivers (Correct answer)
The vehicle is transporting hazardous materials under ADR rules

Correct answer: The vehicle is wide, slow, or requires extra caution from passing drivers

Flashing amber beacons warn other road users to take extra care because the vehicle is wide, slow-moving, or otherwise presents an unusual hazard.

Question 91: Where should a professional driver be especially alert for motorcyclists when operating a large vehicle?

Only on motorways and dual carriageways
Only during poor weather or low-visibility conditions
In mirrors and blind spots, particularly when turning (Correct answer)
Only when travelling above 40 mph in urban areas

Correct answer: In mirrors and blind spots, particularly when turning

Motorcyclists can enter a large vehicle's blind spots undetected and are at severe risk if struck during a turn — constant mirror checks are essential.

Question 92: What role does the driver's attitude play in fuel-efficient driving?

A calm, patient driving style leads to smoother driving, better anticipation, and significantly lower fuel consumption (Correct answer)
Aggressive driving is more fuel-efficient because journeys are shorter
Attitude has no effect on fuel consumption
Only vehicle technology affects fuel consumption

Correct answer: A calm, patient driving style leads to smoother driving, better anticipation, and significantly lower fuel consumption

A calm, patient attitude promotes smoother acceleration, better anticipation of traffic conditions, less aggressive braking, and more consistent speeds — all of which reduce fuel consumption. Stress and impatience lead to aggressive driving patterns that waste fuel.

Question 93: Under UK law, who is responsible for ensuring a load is properly secured on an HGV?

The customer who ordered the goods
Only the person who loaded the vehicle
Only the transport manager
The driver is ultimately responsible for ensuring the load is secure before driving (Correct answer)

Correct answer: The driver is ultimately responsible for ensuring the load is secure before driving

While the loader has a duty to load safely, the driver is ultimately responsible for ensuring the load is secure before and during the journey. The driver can be prosecuted if an insecure load causes an incident, even if someone else loaded the vehicle.
