OR CDL HazMat Practice Test 2 2025

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

The Hazardous Materials (HazMat) endorsement you’re thinking about adding to your Oregon commercial driver’s license (CDL) can yield great career opportunities. Learning to safely transport gasoline, propane, explosives, and other materials considered hazardous can potentially increase your job prospects and income. From Corvallis to Medford, you’ll find various hazardous materials being transported on Interstate 5, and the drivers hauling them have received specialized training. Our second free Oregon DMV CDL HazMat endorsement practice test teaches the essential information you must know to transport these materials. You will be provided with expertly designed instruction to overcome your learning obstacles and get started on the road to success.

Our Oregon DMV CDL HazMat endorsement practice test offers the most innovative training method to help you learn critical information. Getting a HazMat endorsement requires you to complete an entry-level driver training course, undergo a Transportation Security Administration (TSA) background check, and pass an official knowledge test. The official knowledge test challenges you to correctly answer at least 80% of its 30 questions to pass. This practice test uses 30 questions, like those on the official knowledge test, to mimic the actual testing experience and identify the information you should study more. This approach reduces your stress and helps you create an effective study plan.

This Oregon DMV CDL HazMat endorsement practice test gives you a decisive advantage in becoming fully prepared to demonstrate your skills. The practice test is based on the most recent Oregon DMV CDL manual (Oregon CDL Handbook 2025) and is up to date as of December 2025. If you submit an incorrect answer, the practice test displays a thorough explanation of the correct one, using information taken directly from the CDL manual. This approach is in sharp contrast to a study guide that merely trains you to memorize the answers to a series of questions. The practice test is a great resource for eliminating your confusion and increasing your chances of passing the official knowledge test on your first attempt.

Using our series of practice tests is a great way to enhance and refine your driving skills. You can depend on our practice tests to teach you how to operate tanker vehicles, conduct pre-trip inspections, and employ a variety of other valuable driving skills.

Indulge yourself with a bowl of Tillamook ice cream and delight in the expert driving skills you’ll develop using the practice tests at https://driving-tests.org/oregon/.

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.
