About this test

12 min to complete
Available in EN and ES

Need a final study-spree? This Minnesota CDL Air Brakes Marathon is a massive practice test that contains a combination of all 183 questions that we have available for this MN 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”. Delivers some serious studying power! Do your best to complete this mega test!
