The answer options
- So you can travel faster
- So you can see further ahead
- So you can switch to main beam quicker
- So you can be seen by othersCorrect
Why that is the answer
The Highway Code requires you to use dipped headlights at night in built-up areas with street lighting. Because streetlights already illuminate the road, dipped headlights are not needed to help you see further ahead. Instead, their primary purpose is to ensure other road users, such as pedestrians, cyclists, and drivers, can easily see you. Sidelights alone are rarely bright enough to make your vehicle sufficiently visible to others.
How this comes up in the real test
Questions from rules of the road 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.
