Flagger Program

New, exciting changes for CDOT's Flagger Program
C.R.S. 43-5-308 (2)(b)

The purpose of The Flagger Program is to provide certification to entities throughout Colorado to train individuals to become Flaggers. Flaggers are part of the line of defense between the traveling public and individuals working in work zones; they provide safety to all involved parties.

CDOT's Traffic and Safety Engineering Branch has been managing the program since September 2012. We're thankful for your cooperation as we were able to roll out this program to meet the standard of care we believe exists at CDOT.

Please email us at [email protected] for more information.

Please send all COMPLIMENTS of Individual Flaggers and Certified Entities to the [email protected]

We WELCOME and WANT these compliments!!

In the unfortunate situation that you have a complaint, please contact us and we will do what is possible to rectify the issue.

Information for your use

CDOT is still updating the manual, tests, and the reference guide.

In order to become a certified Flagger, a person must contact a Certified Entity to take the required course, meeting all requirements, and pass the exam with an 85% or better.

  1. Do not send renewal certification applications with the QA. Email or mail the application separately.

  2. Mail the QA documents with original signatures and email the other documentation required for QA.
     
  3. Quality Assurance paperwork is the property of the certified entity. Original records shall stay with the entity at the time of proctor turnover. It is the entity's responsibility to maintain paperwork if the proctor or designated contact leave the position. CDOT has a right to suspend or revoke authorization for failure to comply with requirements or submit Quality Assurance at  the CDOT's request.

  4. Any certified entity can train external customers seeking Flagger training; including temporaries, non-employees, and other proctors. A certified entity cannot train it's own proctors.  Test three is no longer allowed to be used for in-house testing, however should be used in in circulation when testing.  All Flagger certification cards for proctors and individuals are to be issued within twenty-four (24) hours of passing the test. 

The most updated information will be communicated on this page rather than via the links. Please contact us if there are discrepancies, or if this information is unclear. These links are updated periodically. If a link is not working, please wait a few moments or email us to obtain the information.

CDOT Flagger examinations for Individuals and Proctors are closed book exams only—no exceptions. The passing score is 85% for both individuals and proctors. CDOT will be releasing the updated manual very soon which highlights this change.

To qualify as a Traffic Control Supervisor within Colorado, a person must have 2,000 verifiable hours of field experience. This does not have to be solely as a Flagger.  

Currently, the CDOT does not accept online training through ATSSA for the Flagger certification. This may be something that will change in the future. The only online certified entity that CDOT accepts for Flagger certification is "Professional Traffic Graphics." We do accept ATSSA in class TCS and ATSSA Flagger in class for proctor certifications. You may also have your ATSSA FIT card.

If you need to obtain your Flagger certification or renew your certification, Certified Entity information is available. Contact the branch to obtain a complete list of Certified Entities. This list is continuously being updated. If the links are not working, please contact us.

Crossing Guard Training is not the same as Flagger Training and Certification. Learn more on CDOT's  Safe Routes to School information page.

For Individuals & Entities

In order to become certified Flagger, a person must contact a Certified Entity and take the required course and pass the exam. Flagger Certification cards are to be issued within 24 hours after passing the exam. Feel free to familiarize yourself with the manual; however, you must take the course to get certified.

Guidelines for Entities

Email or mail original application only.

  • All applications must be accompanied by the proctor's Flagger or TCS certification.
  • All Flagger certifying entities must use this application.
  • Re-apply for certification a minimum of 45 days before the current expiration date.
  • Quality Assurance is due yearly on your expiration anniversary.
  •  All Quality Assurance Documents requiring a signature need be wet signatures. No electronic signatures will be accepted.

Proctors:

  • All proctors must be certified as Flaggers or TCS's before training an individual.
  • All applications must be accompanied by proof that the proctor has been trained. Without this, the application will not be considered.
  • If your entity has an application on file with CDOT, please complete the Proctor Addition/Deletion Form to highlight changes.
  • To obtain testing materials, your entity must be on file, with current certification.

Contact the branch if you are in need of updated Flagger cards. We only use the October 2014 version.

Disclaimer

Certification cards are the sole property of CDOT, and are not to be duplicated or used as a template. This is grounds for revocation. If your entity is in need of more certification cards, contact the branch via email or phone.

All certification cards issued to Flaggers are valid until the noted expiration date on the card—even if the Flagger is no longer working with or for the issuing entity. The card is transferable between entities and must be recognized as valid.
