What is the main purpose of traffic signals?

The primary purpose of traffic signals is to regulate the flow of traffic and enhance safety on the road. Traffic signals serve as a means of communication between vehicles and pedestrians, indicating when it is safe to proceed and when to stop. By directing the movement of traffic, they help prevent accidents and reduce confusion at intersections, thus contributing to safer driving conditions for everyone involved.

While traffic signals can indirectly indicate hazards by controlling traffic flow, their main function is not to serve as entertainment or to inform drivers about speed limits. These other aspects, though important, are not the primary intention of traffic signals. Instead, the regulation of traffic flow ensures orderly navigation through busy or complex driving environments, aiming to minimize collisions and promote an efficient movement of vehicles and pedestrians alike.
