Traffic lights are responsible for a significant number of test failures. Get the rules right and they become one of the easiest parts of the test.
Traffic lights appear on virtually every UK driving test. The rules are clear — but under test pressure, learners make avoidable mistakes. Understanding every light state and junction configuration removes the uncertainty.
Red = stop at the stop line. Red and amber together = prepare to go (do not move yet). Green = go if the way is clear. Amber = stop unless you have already crossed the stop line or are so close that stopping would be unsafe. Amber does not mean accelerate to beat the light — it means stop if you safely can.
