The purpose of a traffic signal is to control the flow of traffic at intersections. Traffic signals are designed to manage the movement of vehicles and pedestrians, ensuring that they safely and efficiently share the roadway. By using a system of colors—red, yellow, and green—traffic signals communicate to drivers when to stop, prepare to stop, or go, thereby reducing confusion and increasing safety at busy intersections.

This regulation helps prevent accidents and gridlock, facilitating a smoother flow of traffic. Traffic signals are strategically positioned at intersections where vehicle and pedestrian traffic converge, making them essential for maintaining order on the roads.

While other options refer to important aspects of traffic management, such as parking, speed limits, and construction warnings, they do not encompass the primary role of traffic signals, which specifically focuses on directing traffic and ensuring safety at crossings.
