Ready for a challenge? This Colorado CDL Hazardous Materials (HazMat) Marathon is a lengthy study tool that contains a mixture of all 75 questions that we have available for this CO 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. As you work your way through the Marathon, you’ll discover that unlike the other Colorado CDL practice tests there are no explanations and no hints here. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. It might take some time, but you can do this!
