What does this sign mean?
- A Low bridge
- B Tunnel ahead
- C Accident hotspot

Why this is the answer
A tunnel can present a number of dangers to large vehicles. Look out for height or width limits and always be aware of your vehicle's size. Reduce speed and turn on your headlights before entering the tunnel. Remove sunglasses if you're wearing them, and remember, your eyes may take a little time to adjust to the sudden darkness.

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.
