traffic signal

A **traffic signal** is a signaling device positioned at road intersections, pedestrian crossings, and other locations to control the flow of traffic. It typically uses a universal color code-red for stop, green for go, and yellow for caution-to manage vehicles and pedestrians safely and efficiently. Traffic signals help prevent accidents, reduce traffic congestion, and promote orderly movement on streets and highways.
