Theory Hub UK Theory Test

You're travelling on a single carriageway road. Why should you keep well back while you're following a large vehicle?

Why this is the answer

When following a large vehicle, keep well back. If you’re too close, you will not be able to see the road ahead and the driver of the long vehicle might not be able to see you in their mirrors.

Why the other answers don't fit

A
To give yourself acceleration space if you decide to overtake — Acceleration space matters once you have decided. First you need to see whether overtaking is safe at all.
C
To leave a gap in case the vehicle stops and rolls back — Rolling back is a risk on a hill start, not the reason for the gap here.
D
To offer other drivers a safe gap if they want to overtake you — Leaving a gap for somebody else to dive into is not what the distance is for.

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.
