You're on a motorway. When can you use hazard warning lights?
- A When a vehicle is following too closely
- B When you slow down quickly because of danger ahead
- C When you're being towed by another vehicle
- D When you're using the hard shoulder as a running lane
Why this is the answer
Briefly using your hazard warning lights will warn the traffic behind you that there's a hazard ahead. Turn them off again when following drivers have seen and responded to your signal.
Why the other answers don't fit
- A
- When a vehicle is following too closely — Hazard lights are not a message to the driver behind you.
- C
- When you're being towed by another vehicle — Being towed is not in itself a hazard to warn anybody about.
- D
- When you're using the hard shoulder as a running lane — An open hard shoulder is an ordinary running lane. There is nothing to warn about.
Where this comes from
- Driving: the essential skills — section 11
- The Highway Code — rule 116

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.
