What term refers to patrol vehicles, traffic lights, signs, barricades, detours, flagmen, or other techniques and device used to regulate movement of vehicles according to prevailing circumstances?

• A. Traffic Control
• B. Traffic Management
• C. Vehicle Regulation
• D. Road Safety Device

Answer: (A)

The term describes the on-site methods and tools used to steer how vehicles move in response to current conditions. Patrol vehicles, traffic lights, signs, barricades, detours, and flagmen are all part of this system, deployed to control the flow of traffic where and when circumstances change—like in work zones, around accidents, or during events. This is all about immediate, practical control of movement to keep people safe and traffic operating smoothly.

Traffic management, while related, is broader and covers planning and coordinating traffic over larger networks and longer timeframes, not the specific, day-to-day control measures at a site. Vehicle regulation isn’t a standard term for this context, and “road safety device” refers more to individual equipment rather than the overall practice of regulating movement.
