About this test

7 min to complete
Available in EN and ES

Ohio is a state filled with industry and innovation that appreciates talented and flexible commercial vehicle drivers, so today, you will be one step closer to becoming one of these more flexible drivers as you practice for your Hazardous Materials (HazMat) endorsement exam. This endorsement will allow you to carry more sensitive and dangerous cargo for household and commercial needs and is required in many job listings, giving you greater driving flexibility. This multiple-choice question test is unique for a few reasons that will help you be best prepared for your upcoming exam. First, the 30 questions were designed by our writers based on both information and key review questions from the HazMat section of the Ohio Commercial Driver License Handbook. Second, each question includes a hint, if needed, and an explanation that will deepen your understanding and help you answer future questions correctly when it matters most: on exam day. We recommend you study often and feel free to revisit and retake this test until you consistently achieve what would be considered a decent passing score on your real exam (80% or higher is recommended). Good luck now and on your upcoming HazMat exam, and as always, drive safely!

Enhance your HazMat endorsement preparation with our straightforward HazMat practice test collection, and consult our HazMat endorsement guide for essential tips and information.
