What is an ATSSA Flagger?

ATSSA Flaggers are trained professionals certified by the American Traffic Safety Services Association (ATSSA) to direct traffic safely around road construction sites, utility work, or other temporary traffic disruptions. Their primary role is to ensure the safety of workers, motorists, and pedestrians by controlling the flow of traffic using stop/slow paddles, flags, or hand signals. ATSSA Flaggers must complete a certification course that covers safety protocols, communication techniques, and relevant state or federal regulations. This certification is often required by employers and government agencies for anyone working as a flagger on public roadways.
