MI CDL Air Brakes Marathon

What to expect on the actual MI CDL exam

  • 25questions
  • 20correct answers to pass
  • 80%passing score

Ready for something a little different? This Michigan CDL Air Brakes Marathon is a massive practice test that contains a combination of all 183 questions that we have available for this MI 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”. Good luck!
