What is the primary function of road signs and traffic signals?

The main idea is that road signs and traffic signals coordinate how vehicles behave so traffic moves smoothly and predictably. They provide rules, warnings, and guidance for what to do at different places—when to stop, yield, turn, or change lanes, and what speed is appropriate—so that drivers act in a coordinated way rather than guessing or reacting in isolation. This coordination helps prevent conflicts between vehicles, reduces bottlenecks, and keeps overall traffic flow steady. That’s why the best answer is about easing and regulating the flow of traffic. Signs and signals aren’t just about knowledge of the route, avoiding every possible danger, or strictly forcing speed limits; those elements are important parts of the system, but the overarching purpose is to create orderly movement and smooth flow across the road network.
