Traffic Lights

Traffic lights are signaling devices used to manage vehicle and pedestrian flow at intersections. They typically display three colors: red, yellow (amber), and green. Red means stop, yellow warns that the light is about to change, and green indicates it's safe to go. Traffic lights are synchronized to optimize flow and safety, often controlled by timers or sensors that detect traffic presence. They help prevent accidents, reduce congestion, and organize movement efficiently, ensuring that all road users pass through intersections safely and in an orderly manner.
