IA CDL Pre-Trip Inspection Marathon
Original questions by our team Based on 2026 IA CDL Handbook
Need one final boost? This Iowa CDL Pre-Trip Inspection Marathon is a gargantuan study tool that contains a combination of all 91 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 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”. It might take some time, but you can do this!
