What authority do flaggers have when directing traffic at worksites?

• A. They have no authority to manage traffic.
• B. Flaggers have the authority to control and regulate traffic around or through worksites.
• C. They can issue fines to any driver.
• D. They can alter road design.

Answer: (B)

Flaggers are on-site traffic control professionals empowered to direct traffic within a work zone to protect workers and motorists. Under the approved traffic control plan, they use standardized hand signals and devices—like stop/slow paddles or illuminated wands—and tell approaching drivers when to stop, proceed, or merge. Their authority covers directing traffic around or through the worksite during flagging operations and may involve coordinating detours or lane closures as planned. They do not possess law-enforcement power to issue fines, and they cannot alter the road design; changes to the roadway come from engineers and the project plan. Their role is to implement the plan, maintain safe distances from workers, and maintain clear communication with drivers to minimize confusion and delays.
