What are the basic components of a traffic control plan?

A traffic control plan is a critical element in managing road safety and ensuring that road users can navigate safely through construction zones or other scenarios that alter the usual traffic patterns. The core components of such a plan primarily revolve around the signs, signals, and markings that provide essential guidance and information to drivers, pedestrians, and other road users.

Signs are pivotal as they offer warnings, information, and regulations that must be followed. Signals, such as traffic lights or electronic message boards, help control the flow of traffic and indicate when to stop or proceed. Markings, including pavement lines and symbols, provide visual cues that delineate lanes, guide traffic movements, and indicate areas where special precautions are needed.

Together, these elements form a comprehensive system designed to manage traffic effectively, reduce confusion, and enhance safety for all users. This makes option B the most accurate description of the basic components involved in a traffic control plan.
