View All PlansAre you ready to upgrade your Missouri commercial driver’s license (CDL), using our second Missouri DOR Hazardous Materials (HazMat) endorsement practice test? The practice test is an important breakthrough in teaching you the rules and regulations you must know to safely transport hazardous materials. Adding a HazMat endorsement to your CDL creates opportunities to increase your income and the types of cargo you’re allowed to transport. Along with these benefits, you’ll have the responsibility of taking the measures necessary to protect property, people, and the environment within the “Gateway to the West” and beyond. Using the practice test, you will better understand how to safely transport hazardous materials, such as gasoline, pesticides, paints, and other materials deemed to be hazardous.
Our second free Missouri DOR CDL HazMat endorsement practice test completes an assessment of your current knowledge level and teaches you the information to expand it. Besides completing an entry-level driver training course and a Transportation Security Administration (TSA) background check, you must pass an official knowledge test to obtain a HazMat endorsement. The practice test allows you to track your progress in absorbing the information crucial to your success. You must correctly answer at least 80% of the 30 questions on the official knowledge test to earn a passing score. The practice test contains 30 questions, similar to those on the official knowledge test, to identify the hurdles you must overcome to ace your official knowledge test.
Compared with traditional study guides, this Missouri DOR CDL HazMat endorsement practice test is a superior resource for targeting your specific learning obstacles. If you get a question wrong, the practice test responds with a full explanation of the correct answer. Study guides are designed to be one-dimensional and offer no feedback to help you correct misinformation. You can trust the instruction you receive from the practice test because it comes directly from the most recent Missouri DOR CDL manual (Missouri CDL Handbook 2025) and is up to date as of November 2025. The information you receive will increase your driving skills, boost your confidence, and make it possible for you to pass the official knowledge test on your first attempt.
Each of our practice tests is expertly designed to maximize your skills. Whether you’re in need of a CDL permit to starting your career or a tanker endorsement to advance it, you can depend on our series of practice tests to help you succeed.
