traffic light
Red-yellow-green indicator
A traffic light is a signal device at road intersections that controls vehicle and pedestrian flow through colored lights—typically red (stop), yellow (caution), and green (go).
The sequence cycles automatically or responds to sensors.
To run a red light is to drive through without stopping.
Also called a stoplight or traffic signal.
