Need one final boost? This Iowa CDL Tanker Vehicles Marathon is a gargantuan study tool that contains a mixture of all 61 questions that we have available for this IA 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!
