AL CDL Air Brakes Marathon

12 min

Fasten your seat belt for one last wild ride of studying! This Alabama CDL Air Brakes Marathon is a gargantuan practice test that contains a mix of all 183 questions that we have available for this AL endorsement. If you make a mistake, 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!
