You're driving a lorry 30 feet long and towing a trailer 15 feet long. What should you do when you see this sign?
- A Find an alternative route to your destination
- B Stop and wait for a police escort
- C Continue past the sign but reduce your speed
- D Carry on; the sign applies to the towing vehicle only
Why this is the answer
The maximum permitted length of vehicle includes any trailer being towed. Make sure you know the total length of your vehicle.
Why the other answers don't fit
- B
- Stop and wait for a police escort — No escort makes an over-length combination fit through a length restriction.
- C
- Continue past the sign but reduce your speed — A lower speed does not make the vehicle shorter.
- D
- Carry on; the sign applies to the towing vehicle only — Length limits apply to the whole combination, trailer included.

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites.
