The answer options
- Other drivers may be dazzledCorrect
- Large vehicles may be wary
- You are not towing a trailer so there is no need
- Other drivers will keep back
Why that is the answer
Rear fog lights are extremely bright and high-intensity. In clear conditions, they can dazzle drivers travelling behind you and obscure your brake lights, making it difficult for others to see when you are slowing down. The Highway Code states you must only use fog lights when visibility is seriously reduced, usually to less than 100 metres, and you must switch them off as soon as conditions improve to avoid blinding other road users.
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.
