Free North Dakota CDL HazMat Practice Test 2024

There are a number of commercial loads that require an extra amount of care, due to their nature as sensitive and possibly toxic or combustible, which are known as hazardous materials. Individuals who are qualified to drive these loads are more versatile than regular CDL holders, and today, you are one step closer to joining their ranks by taking a practice test to prepare for your Hazardous Materials (HazMat) endorsement exam. This 30-question practice test is closely based on information and knowledge-testing questions that the writers of the North Dakota Commercial Drivers License Guide indicated may be on your exam. It is also recommended that you read each question’s accompanying explanation, as these explanations have been written to provide you with a lot of information in compact bites about each subject, to help you answer future questions correctly on your real exam. Feel free to retake the exam as often as necessary until you receive a score that will help you feel more confident about passing your real HazMat exam on the first try (80% or higher is recommended). Good luck right now, and we wish you the best of luck on your new HazMat endorsement soon! Drive safely!

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
