traffic signals
Red yellow green
Traffic signals are the lights at intersections that control vehicle and pedestrian flow—red for stop, yellow for caution, green for go.
The term covers the complete system: the lights themselves, their mounting poles, and the timing mechanisms that coordinate them.
The traffic signals were out after the storm, so police directed cars through the intersection.
