Transportation Security Administration Security Threat Assessment

You must pass a TSA security check every five years to keep this endorsement.
The security check can take 60 days or more to complete.

You must pass another TSA security check if you are coming from another state and your last TSA check was more than 4 years and 9 months ago.

We will verify the date of a previous security check with the TSA.
You must start a TSA security check online at the TSA website or by calling Universal Enrollment Services at 855-347-8371.

Check the status of your case to see if you passed.

Security Threat Assessment Exemption

The Transportation Safety Administration (TSA) has seen a significant increase in the number of Security Threat Assessment (STA) requests. As a result, there have been processing delays and, in some instances, TSA has been unable to complete STAs within the 60-day period that drivers are instructed to submit their application. On September 15, 2022, TSA issued an exemption that permits states to grant certain Hazardous Materials Endorsement (HME) holders a 180-day extension on the STA. DMV has adopted the exemption and is deferring cancellation for individuals whose STA expire on or after July 1, 2022, and on or before December 27, 2022. The deferred cancellation date will be 180 days after the expiration day of an individual’s most recent STA (Expiration + 180 days). Individuals that qualified for this exemption and were cancelled or have a pending cancellation will receive a notice from DMV withdrawing the previous notice that they received.

Individuals that had their hazardous materials endorsement removed as a result of receiving a notice of cancellation may be eligible for a no fee replacement.

If you have questions regarding eligibility for a no fee replacement or this exemption, please contact customer assistance at:

Salem Metro Area: 503-945-5000
Statewide Relay (TTY): 7-1-1

You can check the current status of your CDL at DMV2U - Login (oregon.gov).

This exemption does not affect any other requirements for a CDL.

Hazardous Materials Endorsement holders needing to renew their TSA STA should submit their applications as soon as possible to ensure that they are completed timely.

An "M" restriction means you may drive Class B and Class C passenger vehicles.
An "N" restriction means you may drive Class C passenger vehicles.

Note: We do not know of any Class A passenger vehicles currently driven within Oregon. All passenger endorsements are currently restricted.

To change an "N" restriction to an "M" restriction, you must:

Pass the CDL skills test in a commercial motor vehicle with a gross vehicle weight rating of more than 26,000 pounds; and
Pay the testing and replacement fees.
