When may you use hazard warning lights?
- A When driving on a motorway to warn traffic behind of a hazard ahead
- B When you're double-parked on a two-way road
- C When your direction indicators are not working
- D When warning oncoming traffic that you intend to stop
Why this is the answer
Hazard warning lights are an important safety feature. Use them when driving on a motorway or unrestricted dual carriageway to warn traffic behind you of danger ahead. You should also use them if your vehicle has broken down and is causing an obstruction.
Why the other answers don't fit
- B
- When you're double-parked on a two-way road — They do not excuse illegal parking.
- C
- When your direction indicators are not working — Hazard lights use the same bulbs as the indicators.
- D
- When warning oncoming traffic that you intend to stop — They face both ways and tell oncoming traffic nothing useful.

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.
