Oregon CDL HazMat Practice Test 4 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

The HazMat endorsement is required by the states for drivers of commercial vehicles. The purpose of the HazMat endorsement is to ensure that drivers are aware of the hazards associated with the transportation of hazardous materials. When you need a job that requires the HazMat endorsement, preparing for the CDL knowledge exam is hard. The Oregon CDL manual is overwhelming, filled with information that’s often confusing and hard to remember. You need something where you could supplement the dry information with exam-like practice. This HazMat practice test will help you prepare. We’ve designed it to be the tool that will help you pass the official exam with ease – by covering the same materials that the real exam is based upon. You’ll be getting instant feedback after each question so you’ll know why every answer is correct. The answers are explained with easy-to-follow language. You’ll study at your own pace, and even review specific questions if they give you problems. Good luck!

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.
