The American Traffic Safety Services Association provides online flagger certification. Students register for the online course by clicking the Register Now button on the organization's website.
The online flagger certification course covers five objectives that teach students to be safe and effective flaggers, including understanding the importance of proper flagging, learning and applying the standard flagger skill set, and identifying common flagging signals. Students may take the interactive online course 24 hours per day, and they may download the Flagger Handbook and workbook as part of the course. Students complete the course in four hours and then receive a laminated flagger certification card in the mail.
