What is the purpose of traffic signals?

Traffic signals serve a vital role in the regulation and management of vehicle and pedestrian movement on roadways. Their primary purpose is to control the flow of traffic, ensuring that vehicles and pedestrians move safely and efficiently. By providing clear indications of when to stop, go, or prepare to stop, traffic signals help to reduce the risk of accidents at intersections and busy roadways.

These signals contribute to organized traffic patterns, allowing for smoother transitions between different types of movements, such as cars turning, pedestrians crossing, or cyclists navigating through traffic. In essence, traffic signals are designed to enhance safety and facilitate efficient transportation, making it easier for all road users to coexist harmoniously.
