What do bells hanging across the road warn drivers of?
- A Weight restriction ahead
- B Trams crossing ahead
- C Overhead electric cables ahead
- D Railway level crossing ahead
Why this is the answer
If your vehicle touches bells suspended over the road, they'll obviously ring. This will warn you that your vehicle exceeds the safe travelling height beneath electrified overhead cables ahead. You must stop immediately and either find another route or take advice.
Why the other answers don't fit
- A
- Weight restriction ahead — Weight limits are signed with plated figures.
- B
- Trams crossing ahead — Tram crossings are signed with a tram symbol.
- D
- Railway level crossing ahead — A level crossing is signed with gates or a locomotive symbol.

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.
