The answer options
- Using break lightsCorrect
- Using fog lights
- Using your side lights
- Using the interior lights
Why that is the answer
Pressing your brake pedal illuminates your brake lights, signalling to drivers behind that you are slowing down or stopping. The Highway Code recognises brake lights as a clear signal of your intention, helping following traffic adjust their speed safely. Side lights and fog lights are designed to improve visibility in specific weather conditions, while interior lights are not used to communicate with other road users.
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.
