What are the 3 types of traffic control devices that provide information on laws, hazards, and the roads themselves?

Traffic signs, traffic signals, and road markings are essential traffic control devices that communicate important information to drivers, helping to ensure safety and proper navigation on the roads.

Traffic signs serve various purposes, including warning drivers of hazards, providing regulatory information such as speed limits, and guiding them to their destinations. Signals control the flow of traffic at intersections and pedestrian crossings, indicating when vehicles should stop or proceed. Road markings are used to delineate lanes, indicate turns, and provide additional information regarding road conditions, such as when to yield or stop.

Using these three types of devices effectively helps create a safe and organized environment for all road users. They are standardized and widely recognized, which is crucial for drivers to quickly understand and respond to the information being presented. The other options include elements that do not encompass the official categories of traffic control devices, such as navigation systems, traffic rules, and road maps, which are useful for guidance but do not serve the direct controlling functions that signs, signals, and markings do.
