What is the primary purpose of traffic control devices?

The primary purpose of traffic control devices is to regulate, warn, and guide road users. These devices, which include signs, signals, and pavement markings, are essential in managing the flow of traffic, providing critical information, and maintaining safety on the road. By regulating behaviors, such as stopping at intersections or yielding to pedestrians, they help prevent accidents and promote orderly traffic movement. Warnings, such as caution signs for sharp curves or pedestrian crossings, alert road users to potential hazards, thereby enhancing safety. Additionally, guiding devices, like directional arrows or lane markings, assist drivers in navigating the roadway system effectively, ensuring they know where to go and how to perform maneuvers safely. Overall, these functions are crucial for maintaining an organized and safe traffic environment.
