What is the primary purpose of traffic signals?

The primary purpose of traffic signals is to manage the flow of traffic. Traffic signals play a crucial role in ensuring road safety and efficiency. They control the right-of-way at intersections and pedestrian crossings, helping to regulate the movement of vehicles and pedestrians. By doing so, they minimize the risk of accidents and promote a smoother traffic experience.

Properly functioning traffic signals can significantly reduce congestion by directing vehicles to stop or proceed in an organized manner, thereby keeping traffic moving more efficiently. When drivers and pedestrians abide by the signals, it creates a predictable environment that allows for safer interactions on the road.
