Upon successful completion of the written tests, MVD will provide you with a HazMat Background Check Authorization form to present to a TSA authorized fingerprint collection site identified below.

You may begin the Security Threat Assessment process only after MVD has determined that you have fully qualified for the endorsement by successfully completing all required CDL and HME written tests.

New HME applications can be processed at any MVD offices.

Currently, federal regulations require that all new commercial driver license (CDL) applicants or current CDL holders who are requesting an HME successfully complete a Transportation Security Administration (TSA) fingerprint-based Security Threat Assessment prior to issuance of the endorsement.

The requirement is a result of the U.S. PATRIOT Act (Public Law 107-56, Section 1012), the Safe Explosives Act (Public Law 107-296, Section 1121-1123), ARS § 28-3103(A)(2) and 49 CFR 1572.

No. The three-year testing requirement is a federal regulation for employers transporting hazardous materials to test their drivers every three years.

The Arizona HazMat test is required only when applying for an original CDL, adding the H endorsement to an existing CDL, renewing a CDL or transferring an out-of-state CDL to Arizona while retaining the H endorsement.

During a training session provided by the installers, drivers are cautioned about common substances that contain alcohol, including mouthwashes and medications. If the blood alcohol concentration of the driver, as measured in the breath, is over the preset limit, the driver will not be allowed to start the vehicle.

State law requires the interlock remain installed for at least one year beginning on the date of reinstatement eligibility of your driving privilege or on the date we receive notice of your conviction, whichever occurs later (see ARS 28-3319). You may also contact MVD to determine the date you qualify to have the device removed.

Contact us to verify that you are eligible to have the interlock removed.

If your vehicle has been sold, you must have the device removed by your authorized installer. You will have 72 hours to have the device re-installed into another vehicle. If the device is not re-installed, your driving privilege will be suspended until re-installation is verified.

If your vehicle is stolen, contact your installer to determine a course of action. You will still be responsible for complying with the interlock requirement.
