Theory Hub UK Theory Test

When should you use your vehicle's horn?

Why this is the answer

Only use your horn to warn people of your presence when they may not have seen you. Do not use it to greet others, to show impatience, or to give or claim priority. Your horn must not be used between 11:30pm and 7am in a built-up area, or when your vehicle is stationary, unless another vehicle poses a danger.

Why the other answers don't fit

B
To allow you right of way — The horn confers no priority at all.
C
To greet other road users — It is not a greeting, and using it as one is prohibited at night.
D
To signal your annoyance — Annoyance is never a reason to sound it.

Where this comes from

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.
