The purpose of traffic signals is to:

Traffic signals are crucial for managing the flow of vehicles and pedestrians at intersections and roadways. Their primary purpose is to help maintain order by indicating when vehicles and pedestrians should stop or go, thereby reducing the likelihood of accidents and ensuring a smoother movement through busy areas.

By regulating when different road users can safely proceed, traffic signals help to organize traffic flow and significantly enhance safety for everyone on the road. Drivers can anticipate when to stop or proceed, while pedestrians receive clear directions on when to cross. This synchronization of movements minimizes confusion and reduces potential collisions.

Speed limits are typically indicated on road signs, while traffic signals do not exclusively control pedestrian traffic or inform drivers about road construction events. Instead, traffic signals encompass a wider range of traffic management functions that aim to coordinate both vehicle and pedestrian activity effectively, ensuring that all road users can navigate intersections safely.
