multimedia section.

Traffic signals are lights that tell you when or where to stop or go. They are usually at intersections and are red, yellow and green, from top to bottom. Some locations may have single yellow or red lights.

A yellow traffic signal light means “CAUTION.” The red traffic signal light is about to appear. When you see the yellow traffic signal light, stop if you can do so safely. If you cannot stop safely, cross the intersection cautiously.
