From Florida Department of Transportation Temporary Traffic Control (Maintenance of Traffic) Training Handbook:
“Flagger Training: Required for all personnel flagging traffic.
Training for the Flagger category must be performed by either a Provider listed on the MOT Administration website or personnel holding a current certificate in the Advanced or Intermediate category. Only personnel trained through a Provider will be listed in the TQDBS.
Flagger training requirements are met by completing the Intermediate or Advanced training courses, and Intermediate training requirements are met by completing the Advanced training course.
Refresher courses, for all category levels, are required every four years in order for all personnel to maintain a valid certification.”
