What are "traffic lights"?
Traffic lights are signaling devices used to control the flow of traffic at intersections. They typically have three colors: red, yellow, and green. Red means stop, yellow signals caution or prepare to stop, and green indicates go. These lights help prevent accidents by ensuring that vehicles and pedestrians move safely and in an organized manner. Traffic lights are often placed at busy intersections or areas where controlled movement is needed to manage traffic and pedestrian flow.
Examples
The traffic lights turned red, so all the cars came to a stop.
