FREE IA CDL Air Brakes Marathon 2019
Ready for something a little different? This Iowa CDL Air Brakes Marathon is a massive practice test that contains a mixture of all 119 questions that we have available for this IA endorsement. If you give an incorrect answer, 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!
