What is meant by a red traffic light?

Why that is the answer

A red traffic light is a mandatory instruction to stop. You must stop and wait behind the stop line, and you cannot cross it until a green light appears. The idea of stopping only if it is safe to brake applies to an amber light, not red. Red always means stop, with no exceptions for turning left or proceeding with caution. The Highway Code requires drivers to remain behind the line until the signal changes.

How this comes up in the real test

Questions from road and traffic signs 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.
