traffic lights
Red yellow green
Traffic lights are signal devices at road intersections that control vehicle and pedestrian flow through colored lights—typically red (stop), yellow (caution), and green (go).
Also called stoplights or traffic signals.
We sat through three traffic lights before we could turn left.
To run a traffic light is to proceed through on red.
