MT CDL Hazardous Materials (HazMat) Marathon

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

Ready for something a little tougher? This Montana CDL Hazardous Materials (HazMat) Marathon is a monster of a study tool that contains a mix of all 191 questions that we have available for this MT endorsement. If you select a wrong answer, we’ll remember that question and will display it to you again at the very end of the Marathon 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!
