What is the role of flag persons in work zones?

Flag persons play a crucial role in work zones by ensuring the safety and smooth flow of traffic around construction areas. Their primary responsibility is to stop, slow, or guide vehicles through or around the work zone. This helps to prevent accidents and ensure that both drivers and construction workers are safe. Flaggers are trained to communicate using hand signals and flags to clearly indicate what drivers should do, allowing them to navigate the situation safely.

While directing in emergencies, warning of bad weather, and managing construction supplies may be tasks associated with specific situations or job roles, they do not fall under the direct responsibilities of flag persons in a work zone. Their main objective is traffic control to protect public safety during roadwork activities.
