Our second free Ohio BMVHazardous Materials (HazMat) endorsement practice test prepares you to make strides in advancing your driving career within “The Heart of it All.” Drivers adding a HazMat endorsement to their Ohio commercial driver’s license (CDL) commonly experience increased income and driving opportunities. Using the practice test, you can learn the rules and regulations for transporting hazardous materials. The practice test is a highly effective resource for developing a firm grasp of the procedures you must follow while hauling these materials. Gasoline, propane, and sulphuric acid are examples of hazardous materials that can cause harm through unsafe transportation practices. With help from the practice test, you’ll develop the skills and confidence that protect you from making critical mistakes.

Our Ohio BMV CDL HazMat endorsement practice test gives you a strategic advantage in learning the safety procedures you must follow. You will be required to complete a HazMat training course, undergo a Transportation Security Administration (TSA) background check, and pass an official knowledge test to earn your endorsement. The practice test uses 30 questions, similar to those on the official knowledge test, to identify your misunderstandings and direct your attention to the information you should study more. This approach targets your specific learning obstacles. You’ll be able to create a study plan that allows you to correctly answer at least 80% of the 30 questions on the official knowledge test needed to pass. The practice test is a blueprint for your success.

Feels like cheating.
This felt like cheating to be honest. I waited at the DMV for 3.5 hours and the lady told me at 1605 that she doesn't think I'll have enough time to take tanker and hazmat. I told her all I needed was 5 minutes. I sat down at 1620 and stood up at 1626 (took an extra minute oops) and told her I was done. She looked at me like I had 3 heads and was amazed that I'd passed so quickly. This program will make you 100% within days.

The perfect course to take for hazmat.
The way it is laid out to learn in segments was great but the most helpful thing for me and I think anyone else that may take the hazmat course is the “Hint” button that help me out a lot! I highly recommend “Driving-Tests.Org

Easily Passed On The 1st Try!
I literally would not have received my HazMat & Tanker endorsements without this program. Practice makes perfect and with the help of this program, I passed my HazMat and Tanker knowledge exams without missing a single question! If you need to learn/study quick for your knowledge tests, this is the program for you! 10/10

The practice test is based on the most recent Ohio BMV CDL manual (Ohio CDL Handbook 2025) and is up to date as of December 2025.
