What is the main function of traffic signals?

The main function of traffic signals is to manage vehicle and pedestrian flow. They play a crucial role in maintaining order on the roadways by providing clear and standardized instructions to drivers and pedestrians. Traffic signals are designed to regulate when vehicles should stop or go and when pedestrians can safely cross streets, thus ensuring safety and efficiency in navigating traffic.

Proper management of traffic flow minimizes congestion and reduces the risk of accidents. By controlling the timing of signals, they can adjust the flow in response to changing traffic conditions, facilitating a smoother travel experience for everyone. This systematic control helps prevent conflicts between vehicles and pedestrians, ultimately promoting a safer road environment.
