What is the main purpose of traffic signs and signals?

The main purpose of traffic signs and signals is to control traffic flow and ensure safety. These elements of the roadway are designed to convey critical information to drivers, helping them to make informed decisions while operating a vehicle. For instance, stop signs instruct drivers when to halt, and yield signs indicate when they should give way to other vehicles. Traffic signals manage the flow of vehicles and pedestrians at intersections, reducing the likelihood of collisions and improving overall road safety. By providing essential guidance, traffic signs and signals contribute to a structured and predictable driving environment, which is crucial for preventing accidents and ensuring that all road users can navigate safely.
