stop lights

Intersection control lights

Stop lights are traffic signals that control the flow of vehicles at intersections, cycling through red, yellow, and green to indicate when drivers must stop or may proceed.

The term emphasizes the stopping function—the red light that halts traffic.

Also spelled as one word: The stoplight turned green.

A stop light can also be a brake light on a vehicle.
