Theory Hub UK Theory Test

What should you do before driving into a tunnel?

Why this is the answer

Before driving into a tunnel, you should take off your sunglasses. If you do not, you'll find that your vision is restricted - even in a tunnel that appears to be well lit.

Why the other answers don't fit

A
Switch off your radio — The radio should be on and tuned, not off.
C
Close your sunroof — An open sunroof is not the hazard; what matters is your eyes adapting.
D
Switch on your windscreen wipers — Wipers are for rain, and a tunnel is dry.

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.
