FREE IA CDL Hazardous Materials (HazMat) Marathon 2018

Fasten your seat belt for one last wild ride of studying! This Iowa CDL Hazardous Materials (HazMat) Marathon is a gargantuan practice test that contains a compilation of all 75 questions that we have available for this IA endorsement. If you select a wrong 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. As you work your way through the Marathon, you’ll discover that unlike the other Iowa CDL practice tests there are no explanations and no hints here. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Good luck!
