HI CDL Air Brakes Marathon

Got a couple of hours to spare? This Hawaii CDL Air Brakes Marathon is a gargantuan study tool that contains a compilation of all 183 questions that we have available for this HI 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!

Perfect for

  • First-time HI CDL and CLP applicants
  • CDL holders adding endorsements
  • HI CDL renewal applicants
HI commercial driver's license
