Who Needs National Flagger Certification Training?

Workers who direct vehicular or pedestrian traffic on any worksite must be trained and certified as flaggers. Flaggers use hand signals, signaling devices and other equipment during temporary traffic control (TTC) operations. OSHA-compliant flagger certification protects workers and drivers from traffic accidents on the jobsite.

A TTC zone is required any time the normal flow of traffic on a publicly accessible road is suspended. Certified flaggers may be required during:

  • Construction
  • Utility installation
  • Road maintenance
  • Tree trimming
  • Surveying
  • Emergency response
  • Highway construction
  • Traffic incidents
  • Events (concerts, parades, festivals)
  • And more

This course meets OSHA flagger training standards required for all workers at worksites nationwide. Some locations require additional state-level training. At the end of this training, you will be qualified to act as an OSHA-compliant flagger during temporary traffic control operations.

Testing Requirements

To complete the National Flagger Certification Training course, you must pass all knowledge checks, end-of-module quizzes, interactive activities and a final exam.

Each lesson ends with a quiz. Quizzes include five multiple-choice questions. The final exam is a comprehensive multiple-choice test that contains 10 questions.

During Modules 3 and 4, you will complete 10 illustrated, interactive exercises. In Module 3, you will identify hazards to workers and public safety. You must identify appropriate corrective measures for the same scenarios during Module 4.

What is the MUTCD?

MUTCD is short for the Manual on Uniform Traffic Control Devices for Streets and Highways. The Federal Highway Administration is required to publish the MUTCD and make it available to the public.

This national handbook sets the standards used across the country to construct and maintain traffic control devices on any publicly accessible roadway. MUTCD includes standards for everything from lane markings and stoplights to highway signs and traffic signals. The 11th edition was published on December 19, 2023.

Does National Flagger Certification Training provide an OSHA certificate?

This training fully complies with OSHA standard 1926.201(a). While OSHA requires flaggers on all worksites across the United States to be certified in accordance with the standard of Part 6 of the MUTCD, OSHA does not provide official certification for work zone flaggers.

At the end of this course, you will earn a certificate demonstrating that you have the knowledge and skills necessary to serve as a certified flagger in a TTC zone. You can download and print the certificate of completion as soon as you pass the final exam.

Your state may require supplemental training or extra application steps. Contact your employer or state department of transportation for additional information about state-specific flagger certification requirements.
