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.

Course Learning Objectives

At the end of the National Flagger Certification Training course, you will be able to:

  • Explain the importance of flaggers in maintaining safe and healthy roadwork zones
  • Summarize the typical requirements for flagger certification and industry best practices for recertification
  • Demonstrate the proper use of a stop/slow paddle for communicating effectively with motorists
  • List the components of a temporary traffic control (TTC) zone
  • Recognize the essential tools and personal protective equipment (PPE) for flagging operations, including how and when to use them
  • Evaluate a hazardous traffic-control scenario and apply your training to recommend the appropriate corrective action

National Flagger Certification Training FAQs

What is a flagger?

Flaggers control traffic on worksites. They are often seen near the roadway, directing vehicles with a slow/stop sign paddle. Flagging is a crucial part of work zone safety, especially during construction or road work.

Flaggers use a variety of simple tools, including handheld flags, sign paddles and other hand-signaling devices to communicate with motorists and pedestrians. High-visibility vests, hard hats and other articles of PPE keep flaggers safe on the job.

Flaggers must meet the training, certification and safety requirements found in OSHA standard 1926.201(a) and Part 6 of the Federal Highway Administration’s Manual on Uniform Traffic Control Devices. This course conforms with those regulations and will prepare you to serve as a certified flagger. Certification must be renewed every three years.

How long does it take to complete this course?

This course takes at least 3.5 hours to complete. Along with five lesson modules, the course includes interactive activities, module-end quizzes, periodic knowledge checks, real-world case studies and a comprehensive final exam.

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.

You can take the final exam online, too. As soon as you pass the test, you can immediately download your digital course certificate.

Does certified flagger training expire?

Your certificate is valid for three years. After three years, you must repeat this course to renew your certification. Your state may have additional training or certification requirements. Check with your employer or local government for more information.
