• A. Flag use is limited to immediate emergencies, intersections, and when working on the centerline or shared left turn lanes with opposing traffic.
• B. Flag use is allowed at all times, anywhere.
• C. Flag must be used only at night.
• D. Flag use is not required during emergencies.

Answer: (A)

Flag use is a targeted safety tool that is permitted only in situations where it’s needed to protect workers and regulate traffic. You’ll see flagging used at immediate emergencies, at intersections where traffic control is required, and when workers or equipment are on or near the centerline or in shared left-turn lanes with opposing traffic. In these cases the flag signals drivers to stop or proceed under the flagger’s direction, creating a safe buffer around the work zone. It isn’t something you apply everywhere or at all times; many situations rely on signs, cones, and other devices, and using flags indiscriminately could confuse motorists or create hazards. Flags are used whenever visibility and driver guidance are required—day or night—and with proper training and safety gear. Emergencies still rely on flaggers to quickly communicate and protect everyone involved.
