What you need to know
Ready for a challenge? This North Carolina CDL Air Brakes Marathon is a lengthy study tool that contains a compilation of all 183 questions that we have available for this NC 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”. Give it your best shot!
