What is the protocol for flagger training and certification in Category 6?

• A. Flagger training is optional
• B. Flaggers must be trained and certified per state DOT/MUTCD requirements, with periodic refreshers
• C. Only a one-time training is required
• D. No certification required if under low speeds

Answer: (B)

Flagger training and certification must be kept current according to state DOT and MUTCD requirements. This ensures anyone directing traffic in a work zone understands the proper signals, when to stop or proceed, and how to coordinate with drivers and other workers, along with safe use of flagging devices and personal protective equipment. The credential isn’t a one-time event and isn’t waived at low speeds; most jurisdictions require periodic refreshers or recertification to stay up to date with changes in guidelines and safety practices. So the correct approach is that flaggers must be trained and certified per state DOT/MUTCD requirements, with periodic refreshers.
