You're leaving your vehicle parked on a road. When may you leave the engine running?
- A If you'll be parked for less than 5 minutes
- B If the battery is flat
- C When you're in a 20 mph zone
- D Not on any occasion
Why this is the answer
When parking, all ancillary controls should be switched off and the engine stopped. Make sure that the handbrake is applied firmly before leaving the vehicle.
Why the other answers don't fit
- A
- If you'll be parked for less than 5 minutes — No length of time makes it acceptable.
- B
- If the battery is flat — A flat battery is a reason to charge it, not to leave an engine running in the street.
- C
- When you're in a 20 mph zone — The speed limit of the road has nothing to do with it.
Where this comes from
- Driving: the essential skills — section 9
- The Highway Code — rule 123

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.
