AZ CDL Air Brakes Marathon

Fasten your seat belt for one last wild ride of studying! This Arizona CDL Air Brakes Marathon is a super-challenging practice test that contains a combination of all 183 questions that we have available for this AZ 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”. Delivers some serious studying power! Do your best to complete this mega test!

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
