You're going through a long tunnel. What will warn you of congestion or an incident ahead?
- A Hazard warning lines
- B Other drivers flashing their lights
- C Variable message signs
- D Areas with hatch markings
Why this is the answer
Follow the instructions given by the signs or by tunnel officials. In congested tunnels, a minor incident can soon turn into a major one, with serious or even fatal results.
Why the other answers don't fit
- A
- Hazard warning lines — Road markings are fixed and cannot tell you about today's incident.
- B
- Other drivers flashing their lights — A flash means only that somebody is there.
- D
- Areas with hatch markings — Hatching separates traffic. It carries no live information.

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.
