Theory Hub UK Theory Test

You're about to overtake. What should you do when you see this sign?

Why this is the answer

You will not be able to see any hazards that might be hidden in the dip. As well as oncoming traffic, the dip may conceal • cyclists • horse riders • parked vehicles • pedestrians in the road.

Why the other answers don't fit

A
Overtake the other driver as quickly as possible — Speed does not help you when the road ahead is hidden.
B
Move to the right to get a better view — Moving right into a blind dip is the danger itself.
C
Switch your headlights on before overtaking — Lights do not let you see into a dip.

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.
