What does this sign mean?

Why this is the answer

You need to know the length of your vehicle as well as its weight, height and width. Places where the length of your vehicle may be relevant are • road tunnels • level crossings • ferries • bridges.

Why the other answers don't fit

A
Warning of lorry crossing a one-way road — A warning sign would be triangular, not a red-ringed prohibition.
C
No entry for vehicles over 32.6 tonnes — A weight limit is shown in tonnes, not in feet and metres.
D
Warning of lorry straight ahead — Again, a warning would be triangular.

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. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
