LGV LGV Road Signs & Highway Code 2 — Questions and Answers
Question 1: What is the national speed limit for an LGV over 7.5 tonnes on a single carriageway road?
- 50 mph (Correct answer)
- 60 mph
- 40 mph
- 55 mph
Correct answer: 50 mph
LGVs exceeding 7.5 tonnes are restricted to 50 mph on single carriageway roads, which is lower than the 60 mph limit for cars on the same road type.
Question 2: A broken white line in the centre of the road that is longer than the gaps means:
- Hazard warning line — do not cross unless safe (Correct answer)
- Lane marking only — free to cross
- Edge of carriageway
- No overtaking in either direction
Correct answer: Hazard warning line — do not cross unless safe
When the white centre line has longer marks than gaps, it is a hazard warning line indicating a hazard ahead. Drivers should not cross it unless it is safe and necessary.
Question 3: A 'No entry' sign is which shape and colour?
- Red circle with white horizontal bar (Correct answer)
- Red triangle with white bar
- White circle with red bar
- Blue rectangle with white bar
Correct answer: Red circle with white horizontal bar
No entry signs are circular with a red background and a white horizontal bar. They prohibit entry to all vehicles from that direction.
Question 4: When must an LGV driver use hazard warning lights?
- When the vehicle has broken down and is a temporary obstruction (Correct answer)
- At all times when driving at night
- When driving slowly in traffic
- Whenever reversing
Correct answer: When the vehicle has broken down and is a temporary obstruction
Hazard warning lights should only be used when the vehicle is stationary and is a temporary obstruction, or briefly on a motorway to warn following drivers of a hazard ahead.
Question 5: What does a yellow box junction painted on the road mean?
- Do not enter the box unless your exit is clear (Correct answer)
- Give way to vehicles already in the box
- Stop before entering and check for clearance
- Park only in emergencies
Correct answer: Do not enter the box unless your exit is clear
You must not enter a yellow box junction unless your exit road or lane is clear. The only exception is when you are turning right and are only prevented from doing so by oncoming traffic.
Question 6: Which sign indicates that LGVs must use the left lane only on a motorway?
- Rectangular sign showing lorry with arrow pointing left (Correct answer)
- Circular sign with lorry and left arrow
- Triangular sign with lorry symbol
- Diamond sign with lane markings
Correct answer: Rectangular sign showing lorry with arrow pointing left
Rectangular signs on motorways with a lorry symbol and directional arrow indicate lane restrictions for goods vehicles, directing them to the appropriate lane.
