What are the three types of traffic control devices?

• A. Signs, Pavement Markings, and Signals
• B. Signs, Signals, and Pavement Markings
• C. Traffic Cones, Signs, and Signals
• D. Pavement Markings, Signals, and Signs

Answer: (B)

Three main categories guide drivers on the road: signs, signals, and pavement markings. Signs provide rules, directions, and warnings you must follow. Signals—such as traffic lights and pedestrian signals—control when you can proceed, stop, or turn. Pavement markings are painted on the road surface to show lanes, crosswalks, and where to stop or yield. Together, these three types communicate essential guidance and rules to drivers at all kinds of intersections and roadways. Other devices you might see, like construction cones or barriers, are temporary or supplemental tools, not part of the standard three-category system.
