Fasten your seat belt for one last wild ride of studying! This North Carolina CDL Hazardous Materials (HazMat) Marathon is a massive practice test that contains a mixture of all 100 questions that we have available for this NC 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”. Give it your best shot!
