What should be done with traffic control devices when performing a drill on a live street?

• A. Coordinate with local authorities, use spotters, and set up warning devices to guide traffic, follow approved route.
• B. Use only standard street signs and ignore spotters.
• C. Do not coordinate with authorities to keep drill confidential.
• D. Block off all traffic without warning devices.

Answer: (A)

In a live-street drill, safety hinges on having a formal traffic control plan and clear authority to manage the roadway. Coordinating with local authorities ensures you have the legal permission, required oversight, and a defined route that minimizes risk to the public. Using spotters provides real-time eyes on the traffic environment—watching for approaching vehicles, pedestrians, or unexpected changes—and allows quick, coordinated communication with the driver. Setting up warning devices, such as cones, signs, and other visibility tools, guides motorists smoothly through the drill zone and alerts them to temporary conditions. Following the approved route keeps the operation predictable and prevents wandering into unfamiliar or hazardous stretches of the street.

This approach reduces the chance of collisions, misunderstandings, or disruptions to nearby residents and other responders, and it keeps the drill within established safety and legal parameters. Conversely, proceeding without authority, skipping spotters, or blocking traffic without warnings creates unpredictable dangers for both trainees and the traveling public.
