To Qualify/Apply
You must apply in person at a DMV office, and you must:

Note: You are required to pass the Hazardous Materials Endorsement Test every time you renew your license.

Transportation Security Administration (TSA) Criminal Background Check
On May 5, 2003, the U.S. Department of Transportation, Federal Motor Carrier Safety Administration (FMCSA) and TSA published regulations under the USA PATRIOT Act of 2001 requiring all commercial motor vehicle operators to submit fingerprints and pass a TSA criminal background check to obtain a security clearance from TSA before issuance of a CDL that includes a HAZMAT endorsement:

  • Applicants for a HAZMAT endorsement (including some applicants exchanging an out-of-state license that contains a HAZMAT endorsement) will be required to obtain a security clearance from TSA before issuance of a HAZMAT endorsement. Applicants must obtain an Oregon Driver License before contacting the TSA Agent to begin the criminal background check.
  • HAZMAT endorsement holders must obtain a security clearance every five years to retain their HAZMAT endorsement.

The criminal background check can take 60 days or more to complete.

Applicants that currently have a HAZMAT endorsement in another state and wish to obtain an Oregon CDL with HAZMAT endorsement must obtain another background check unless DMV can verify that a HAZMAT security clearance was granted within the previous four years, nine months. If between four years, nine months and five years has elapsed since the security clearance was granted, the applicant may be eligible for a 60-day temporary permit authorizing them to haul hazardous materials while completing a new background check. If you have already completed a background check in the previous state, DMV will verify the date of the check with TSA.  If DMV cannot verify the background check results, DMV cannot issue a CDL with HAZMAT endorsement or issue a temporary permit.

Only one 60-day temporary permit will be issued.

Applicants issued a CDL without a HAZMAT endorsement may be eligible for a no-fee replacement to add the HAZMAT endorsement upon receipt of a favorable background check. If the original CDL issuance date and the date the applicant starts the background check are within 30 days of each other, the applicant is eligible for a no-fee replacement to add the HAZMAT endorsement.

If you have completed a background check for a Transportation Worker Identification Card (TWIC), you may be eligible for a reduced fee HAZMAT background check. When you initiate the HAZMAT background check, as described below, you'll have the opportunity to determine whether that option is best for you.

In Oregon, the HAZMAT background checks must be initiated online with TSA at https://hazprints.tsa.dhs.gov or by calling (877) 429-7746. At that time you will complete an application, arrange for payment of appropriate fees, establish identification requirements and select a fingerprint collection site. Fingerprint collection sites are scattered across the country and you may schedule submission of your fingerprints and proofs of identity at any of those that are operated by the TSA contract agent.

Note: If you already have a HAZMAT endorsement, do not initiate a background check until notified by DMV that you need to do so.

Tips for Completing Your Application

  • Make sure you include your home address and telephone number in case the TSA agent needs to contact you with questions about your application.
  • If you have ever been issued an Alien Registration Number, include the number on the application, even if you are now a citizen of the United States and have a Social Security Number.  The Alien Registration is not your Naturalization Number.  Do not include the "A" in front of your Alien Registration Number - only enter the 9 digits. If your number only has 8 digits enter a "0" at the front of the number.
  • When filling in number fields, do not use dashes, spaces or hyphens.  Only enter the numbers.
  • Be sure to list military service and approximate date of discharge.  Do not enter a month and year only or just the year. You must enter a complete date in the date of discharge field.

At the time you submit fingerprints for the criminal background check, you will be required to show the TSA representative your Oregon Driver License and proof of legal presence.

For additional information on requirements for the criminal background check, location(s), hours of operation of a fingerprint collection site, to complete the application, submit fees, fingerprints, or check the status of your background check, visit the TSA Web site or call (877) 429-7746.

TSA will send the results of the background checks to you and DMV. If TSA grants the clearance and you are applying for an original hazardous materials endorsement, contact DMV to complete requirements.

About Hazardous Material
