View All PlansMost likely, you’ve heard there are great benefits to adding a Hazardous Materials (HazMat) endorsement to your Wisconsin commercial driver’s license (CDL). Our second free Wisconsin DMV CDL HazMat endorsement practice test can provide you with the skills to qualify for more driving opportunities and possibly increase your income. The practice test focuses your attention on overcoming the learning obstacles in the way of your success. You’ll feel like doing the Lambeau Leap once you experience the exceptional results the practice test produces. Whether it’s gasoline, sulfuric acid, or another hazardous substance, the practice test will teach you the rules and regulations for safely transporting it.
Our Wisconsin DMV CDL HazMat endorsement practice test provides clear and comprehensive instruction for eliminating your misconceptions. You must complete an entry-level driver training course, undergo a Transportation Security Administration (TSA) background check, and pass an official knowledge test to earn a HazMat endorsement. The practice test includes 30 questions, mimicking those on the official knowledge test, to analyze your knowledge gaps and identify the information you must learn to succeed. You must correctly answer at least 80% of the 30 questions on the official knowledge test to pass. With the practice test, you’ll gain insight into the types of questions that could be stumbling blocks to achieving the required minimum passing score.
This Wisconsin DMV CDL HazMat endorsement practice test delivers impressive results using authoritative information. The practice test is based on the most recent Wisconsin DMV CDL manual (Wisconsin CDL Handbook 2025) and is up to date as of October 2025. If you get a question wrong, the practice test takes information from the CDL manual to provide you with a detailed explanation of the correct answer. Unlike the practice test, study guides are one-dimensional and make you research the information to correct your misunderstandings. The practice test offers convenient access to the information you must know and increases your chances of passing the official knowledge test on your first try.
Spending time studying with our series of practice tests can expand and refresh your driving skills in a time-efficient way. You can prepare for your CDL permit, recognize road signs, and master other important driving skills.
You can learn some new dance moves at the Pulaski Polka Days, but you can develop classic driving skills with the practice tests at https://driving-tests.org/wisconsin/.
