Flagger Training

Washington State certification

This 8-hour class prepares students with the necessary knowledge and skills to do the job of a flagger—enhancing the safety of both workers and drivers in a work zone. The Washington certification is also valid in Oregon, Idaho, and Montana. WSDOT does not allow online training, but we offer in-person classes in various locations around the state.


What’s included:

  • 8-hour in-person course
  • Certification exam

You will earn:

  • Washington State Traffic Control Flagger certification (valid for 3 years) 


  • Must be 18 years old
  • Valid government-issued photo I.D. card

This is the sign you've been waiting for.

Flagger certification is the first step to a new career. Flaggers with more than 2000 hours of work zone experience (1-3 years full-time) are eligible to earn a Traffic Control Supervisor certification.
