What you need to know
Ready for one final challenge? This North Dakota CDL Air Brakes Marathon is a super-challenging study tool that contains a combination of all 183 questions that we have available for this ND 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”. It might take some time, but you can do this!
