What are traffic controls?

Traffic controls encompass a broad range of devices or systems specifically designed to manage and direct traffic flow on roadways. This includes not only traffic lights but also road signs, pavement markings, and traffic signals. These tools work together to ensure that vehicles and pedestrians can navigate safely and efficiently, maintaining order on the roads. By understanding traffic controls in this comprehensive manner, drivers can better recognize how various elements contribute to safe driving conditions and compliance with the rules of the road.

The other options are more limited in scope. For instance, while traffic lights are certainly a crucial component of traffic controls, they do not cover the full breadth of what traffic controls entail, which includes signs, signals, and other mechanisms. Similarly, speed limit signs are just one type of traffic sign, and pedestrian walkways, though important for safety, do not directly manage traffic flow in the way that is outlined in the correct definition.
