If you’ve obtained your Commercial Driver’s License (CDL), you are likely familiar with transporting cargo through Oregon. From the Cascade Mountain Range and coastal mountains to the high desert, driving here is full of challenges – and chances to grow your career. Adding the Hazardous Materials (Hazmat) endorsement to your CDL is an effective way to expand your opportunities and potentially earn higher pay!

The Hazmat endorsement permits drivers to transport materials classified as hazardous by the U.S. government. In the Beaver State, hazardous cargo includes gasoline, biodiesel, industrial chemicals, and agricultural products such as pesticides. Major employers that rely on Hazmat drivers include Chevron Corporation in Portland (petroleum products distribution), Schnitzer Steel Industries also in Portland (scrap metal processing and chemical transport), and Intel in Hillsboro (which uses industrial chemicals in semiconductor manufacturing). With so many employers willing to pay a premium for HazMat-endorsed drivers, it makes a lot of sense to add this to your CDL!

Obtaining the endorsement involves several required steps. First, you must ensure that all Entry-Level Driver Training (ELDT) requirements have been met. The next step is fingerprinting and a background check by the Transportation Security Administration (TSA). Because TSA results may take weeks, drivers are encouraged to study and prepare during that time for the final step: the Oregon DMV HazMat Knowledge Test. Covering federal regulations, hazardous substance handling, packaging, quantity limits, and safe transport configurations, this 30-question test requires a score of at least 80% to pass (Oregon CDL Handbook 2025).

Best test experience ever.
Well would have to say your AI interactive with question either giving you examples or breaking the question down, but being able to go over any questions that you got wrong was helpful it was the best test experience that I have ever had. Went into DMV the day after I passed my ELDT training and took my Hazmat test and passed with know wrong answers you made it very easy thank you very much was a very good experience and process.

So this was extremely helpful.
I studied for my hazmat, doubles and triples, and tanker endorsements and studied everything within 3 days. I had a scheduled testing date the same week at the dmv and passed every single test! this site is truly worth the buy and is well worth it. Thank you for all the help provided! 😊 Would definitely recommend.

About the Oregon CDL

That’s quite a list of testable topics, and the performance requirement leaves little margin for error. As such, our experts have created practice tests to help ensure you pass on your first attempt. Our practice tests focus on the material you’re likely to see on the official exam, leaving out untested information. You’ll get immediate feedback after each response so that you’ll learn as you go, instead of waiting until the end for corrections. Once you’ve aced this one, be sure to check out others from our multi-set series of practice tests: https://driving-tests.org/oregon/or-cdl-hazmat-practice-test/.

After you have ensured all ELDT requirements have been filled, received your TSA clearance, and worked diligently with our practice tests, you should be ready. Simply bring the required documents to the DMV, pay the fees, and pass the test!
