IMPORTANT: First watch the video for this test (top of this page), then take the following practice test. You should do well on just your first attempt. Repeat watching the video and taking this test until you get 100%. Next, move on to Hazardous Materials Test #4. Repeat this same routine for the rest of the Hazardous Materials training modules before taking the Hazardous Materials DMV Simulated Exam, which has the same number of questions and the same time limit as your official state exam, and is different each time you take the exam.

This CDL Hazardous Materials test will prepare you to pass EVERY state’s DMV HAZMAT exam. You must have a commercial driver license (CDL) with a hazardous materials endorsement before you drive any size vehicle that is used to transport hazardous materials as defined in 49 CFR 383.5. You must pass a written test about the regulations and requirements to get this endorsement. On the official DMV written exam, you must get at least 80% to pass.
