Ready to put your new knowledge to the test? This California CDL Hazardous Materials (HazMat) Marathon is a monster of a practice test that contains a compilation of all 100 questions that we have available for this CA endorsement. If you make a mistake, 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”. Delivers some serious studying power! Do your best to complete this mega test!
