- Direction indicators may not work
- They may be confused with brake lightsCorrect
Why that is the answer
Rear fog lights are high-intensity red lights designed to make your vehicle visible in thick fog. If you leave them on when visibility improves, they can dazzle drivers behind you and be easily confused with your brake lights. This makes it harder for following traffic to notice when you actually brake. Leaving fog lights on will not overload your electrics, but the Highway Code states you must turn them off when visibility improves.
How this comes up in the real test
Questions from vehicle handling 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.
