What should you do if the warning light for your anti-lock braking system (ABS) stays on?
- A Check the brake-fluid level
- B Have the warning light bulb changed
- C Check that the parking brake is released
- D Have the brakes checked immediately
Why this is the answer
If any warning light shows while you're driving, it indicates a fault that needs prompt attention. If the ABS warning light shows, have the braking system checked before driving further.
Why the other answers don't fit
- A
- Check the brake-fluid level — Fluid level is worth checking and is not what this light is telling you.
- B
- Have the warning light bulb changed — Changing the bulb hides the warning rather than answering it.
- C
- Check that the parking brake is released — The parking brake 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.
