Ready for something a little different? This Oregon CDL Hazardous Materials (HazMat) Marathon is a lengthy study tool that contains a compilation of all 192 questions that we have available for this OR endorsement. If you give an incorrect answer, 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”. Delivers some serious studying power! Do your best to complete this mega test!

Enhance your HazMat endorsement preparation with our straightforward HazMat practice test collection, and consult our HazMat endorsement guide for essential tips and information.
