Flagger - Train the Trainer

This is a specialized course used to qualify contractor's personnel to train employees to act as flaggers on MnDOT construction projects. Attendees will meet MnDOT's flagger training requirements contained in the traffic control special provisions. The course includes review of Field Manual flagger requirements and related layouts, discussion of safe practices, flagger attire, and flagger responsibilities.


Classes are completed for 2024. Flagger Train the Trainer 2025 qualification classes will be announced in December 2024.


Once the flagger is trained, the trainer will sign, date, and enter their qualification number into the card located in the back of their flagger’s handbook. 

How often you train your flaggers is up to the contractor. It is recommended that flaggers are trained every year. By training your flaggers every year your records reflect current training dates and flaggers would be up to date on any changes in procedures.

Training contractors
