NH CDL Hazardous Materials (HazMat) Marathon

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

Ready to put your new knowledge to the test? This New Hampshire CDL Hazardous Materials (HazMat) Marathon is a lengthy study tool that contains a mix of all 192 questions that we have available for this NH endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Good luck!
