Free Oklahoma CDL HazMat Practice Test 2023 | OK

As Oklahoma has been named the “best place in the world to do business in oil and gas” by the Frasier Institute in 2012, it is no surprise that the state needs flexible commercial drivers who have their Hazardous Materials (HazMat) endorsements to both carry these loads and benefit from this industry. Today, you will take a practice test that brings you one step closer to gaining this flexibility and being able to carry more dangerous loads safely, preparing you for your real HazMat exam. Our writers have created this 30-question multiple-choice practice test based closely on information from the Oklahoma Commercial Driver License Manual, and the highlighted review questions that the manual’s writers indicated may be on your exam. Unique to our exams are our carefully written question explanations, which are designed to help you better understand the subject of each question, so that you can answer future questions about each subject correctly the very first time. Read these explanations carefully, use each question’s hint if you should need it, and feel free to retake this practice test as often as necessary until you comfortably achieve a passing score that may help ensure success for the real exam (80% or higher recommended). Good luck with your future HazMat endorsement, and drive safely!
