Traffic lights tell you when to go or stop at an intersection. Follow the links in the traffic light image below to learn what the colours of traffic lights mean.

traffic light: red at the top, orange in the middle and green at the bottom

A red light means stop. In some countries, you can make a left turn after you stop and yield to pedestrians and vehicles in your path.

An orange or yellow light means that a red signal is about to appear. You should stop if you can do so safely. If you can't stop, look out for vehicles that may enter the intersection.

A green light means go, but before you move ahead, you must let any vehicles or pedestrians remaining in the intersection get through.
