Traffic signals play a critical role in controlling the flow of traffic and ensuring safety for all road users, including drivers, pedestrians, and cyclists. By providing clear and standardized signals such as red, yellow, and green lights, traffic signals regulate when vehicles must stop or proceed, helping to prevent accidents and maintain orderly traffic flow. This system minimizes confusion and enhances predictability on the road, allowing drivers to make safer decisions.
