What role do traffic signals play in safe driving?

Traffic signals are essential for regulating vehicle movement and promoting safety on the road. Their primary function is to control the actions of vehicles and pedestrians at intersections and crosswalks. By using a system of lights that change at regular intervals, traffic signals communicate when it is safe for vehicles to proceed, when they must stop, and when pedestrians can cross. This organization helps prevent accidents by providing clear instructions to all road users, reducing confusion and potential conflict points.

While other factors such as vehicle speeds, license requirements, and traffic flow enhancements are important considerations in overall road safety and traffic management, they are not the main roles of traffic signals. Instead, the core purpose of traffic signals is to manage and regulate movement to maintain order and safety on the roads.
