This is the fourth of four different HazMat CDL practice tests that we offer. Please take all of our free practice tests to ensure that you score well on the big day! The HazMat test is the most difficult of all CDL endorsement exams. The proper handling and transportation of hazardous materials are critical to public health and safety.

Our free Hazmat CDL practice test #4 contains 10 questions. You may not skip any of the questions. There is no time limit on the test. For maximum practice, we highly recommend taking each of our free CDL hazmat practice tests at least once.

Our Hazmat CDL practice test database contains hundreds of questions based on federal regulations. If you need more practice or want to improve your score, click the ‘Restart Quiz’ button at the end of the test. The questions will be presented in a different order but they’ll be the same questions you already answered. The second time around you should know the answers.

Feel free to retake this test as many times as you’d like. Once you receive your score there will be a button to View Questions. Wrong answers will be highlighted in red. The correct answer will be in a green box outlined in green.

Being the driver of a commercial vehicle is a huge responsibility. The written CDL test isn’t that bad. The actual driving test is rigorous. Inspectors do not want anyone on the road who isn’t capable of handling a big rig. Make sure you practice your driving and especially BACKING UP.

Congratulations on your decision to become a commercial driver!
