Which list correctly identifies the three types of traffic control devices?

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

Answer: (B)

Three main types of traffic control devices are signs, signals, and pavement markings. Signs provide regulatory, warning, or directional information to help you understand and follow the rules. Signals regulate traffic flow with lights or other indicators, telling you when to stop, go, or proceed with caution. Pavement markings are painted on the road itself—like lane lines, stop lines, and arrows—that guide where you should be and how you should move, even when there are no signs present.

The best list includes all three categories: pavement markings, signs, and signals. The order doesn’t matter, since they’re consecutive categories that cover how road users are guided and controlled. Some options might mention temporary tools or list traffic lights separately, but in standard terminology, traffic lights are a type of signal, and pavement markings and signs remain distinct categories.
