The answer options
- Turn off the radio
- Turn on your headlights
- Turn the engine offCorrect
- Apply your steering lock
Why that is the answer
When you stop and wait at the side of the road, you must turn off your engine. Leaving the engine idling wastes fuel, accelerates engine wear, and creates unnecessary noise and harmful air pollution. The Highway Code instructs drivers to turn off their engines when stationary for any length of time. While applying the steering lock or turning off the radio may be helpful, turning off the engine is the legal requirement.
How this comes up in the real test
Questions from safety and your vehicle appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
