From Georgia Department of Transportation Certifications & Training website:
“All flaggers doing any flagging on the State Highway System must have received training and a certificate upon completion of the training. This includes all work, whether by contract or by permit, such as roadway construction, utility accommodations, etc. All costs for providing certified flaggers will be borne by the contractor, utility company, or any other entity granted permission to encroach upon right of way.
Failure to provide certified flaggers as required above shall be reason for suspending work regarding the flagger(s) until a certified flagger can be provided. Flagger training and certification can be obtained through training organizations that provide certified American Traffic Safety Services Association (ATSSA) or National Safety Council (NSC) programs or from ATSSA or NSC themselves.”
