Hazardous Materials Endorsement

In order to comply with the threat assessment measures required by the U.S.A. Patriot Act, all individuals who hold a commercial driver license with a hazardous materials endorsement must have their fingerprints recorded.

If you do not currently hold a hazardous materials endorsement, you will need to complete the threat assessment before the endorsement can be issued to you. If you currently hold a hazardous materials endorsement and you are renewing your commercial driver's license, you will need to complete a new threat assessment.
