What is the purpose of traffic signals?

The purpose of traffic signals is to control the flow of traffic and ensure safety at intersections. Traffic signals are essential tools in road safety and traffic management. They provide clear instructions to drivers and pedestrians about when to stop, go, or yield, which helps in preventing accidents and improving overall traffic efficiency. By regulating the movement of vehicles and pedestrians, traffic signals help to manage the interactions at intersections, where conflicts can often occur.

The implementation of traffic signals reduces confusion on the road by providing visual cues that everyone understands, leading to smoother traffic flow and safer crossing conditions for pedestrians. Proper adherence to these signals is crucial for maintaining order on the roadways, thereby fostering a safe driving environment for all users.
