LGV LGV Road Signs & Highway Code 3 — Questions and Answers
Question 1: What is the meaning of a red circle sign with a white background and a number inside?
- Maximum speed limit (Correct answer)
- Minimum speed limit
- Recommended speed
- Speed advisory for lorries only
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 2: On a motorway, which lane are LGVs over 7.5 tonnes generally prohibited from using?
- The third lane (lane 3) on a three-lane motorway (Correct answer)
- The first lane (lane 1)
- The second lane (lane 2)
- Any overtaking lane
Correct answer: The third lane (lane 3) on a three-lane motorway
LGVs over 7.5 tonnes are not permitted to use lane 3 (the outside lane) on motorways with three or more lanes. They may use lanes 1 and 2.
Question 3: A sign showing a red circle with a lorry and a car side by side with a diagonal red line means:
- No overtaking by goods vehicles (Correct answer)
- No parking for lorries
- Lorries and cars must use separate lanes
- Lorries prohibited on this road
Correct answer: No overtaking by goods vehicles
A red circle containing a lorry overtaking a car with a diagonal line through it is a 'no overtaking by goods vehicles' prohibition sign.
Question 4: What does a rectangular green sign on a motorway generally indicate?
- Directions to motorway destinations (Correct answer)
- A mandatory motorway instruction
- A warning of a hazard ahead
- A service station location
Correct answer: Directions to motorway destinations
Green rectangular signs on motorways provide directional information, showing routes to destinations and junction numbers ahead.
Question 5: At a level crossing with no barriers, a steady red light means:
- Stop — a train is approaching (Correct answer)
- Slow down and prepare to stop
- Stop only if a train is visible
- The crossing is clear to proceed
Correct answer: Stop — a train is approaching
A steady red light at a level crossing means you must stop. A train is approaching and it is extremely dangerous to proceed. LGV drivers must always treat level crossings with great caution due to vehicle length.
Question 6: What is the significance of the Highway Code rule that drivers must not flash headlights to convey any other message than 'I am here'?
- Flashing can be misinterpreted as giving way and cause accidents (Correct answer)
- It is only allowed at night
- It is not mentioned in the Highway Code
- Flashing is only for warning of police ahead
Correct answer: Flashing can be misinterpreted as giving way and cause accidents
The Highway Code states headlights should only be flashed to let other road users know you are there. Flashing to indicate 'after you' or 'go ahead' can be misinterpreted and cause collisions.
