What is a work zone traffic controller?

Work Zone Traffic Controllers, also known as flaggers, are professionals responsible for managing and directing vehicle and pedestrian traffic through construction zones, road maintenance sites, or other temporary work areas. They help ensure the safety of workers, drivers, and pedestrians by using signs, signals, and flagging devices to guide traffic. Their duties often include setting up warning signs, communicating with construction crews, and monitoring traffic flow to prevent accidents or confusion. Proper training and certification are typically required, as these roles are critical for maintaining safety standards in work zones.
