    UT CDL Air Brakes Marathon

    • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
    • Based on 2025 UT commercial driver's license manual
    • Updated for March 2025

    Got a couple of hours to spare? This Utah CDL Air Brakes Marathon is a massive practice test that contains a compilation of all 183 questions that we have available for this UT 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”. Give it your best shot!
