What is the primary purpose of traffic signals?

The primary purpose of traffic signals is to manage traffic flow and ensure safety. Traffic signals are strategically placed at intersections, pedestrian crossings, and other key points to control the movement of vehicles and pedestrians. They help establish a clear order of operations for when cars should stop, go, or yield, reducing the likelihood of accidents. By regulating traffic based on real-time conditions, signals contribute to a smoother flow of traffic and enhance overall safety for both drivers and pedestrians. This systematic approach to traffic control allows for more organized intersections and decreases the potential for collisions, making roads safer for everyone.
