Your car's ignition warning light comes on during a lesson. What fault does this indicate?
- A The engine is overheating
- B The battery needs charging
- C The charging system is faulty
- D The oil level may be low
Why this is the answer
The ignition warning light should go out once the engine has started. If it comes on during normal driving, this would indicate a fault with the charging system. Have it checked.
Why the other answers don't fit
- A
- The engine is overheating — Overheating has its own temperature gauge and warning.
- B
- The battery needs charging — A flat battery shows as poor starting; this light points at the charging system.
- D
- The oil level may be low — Low oil has its own warning light.

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.
