IN CDL Hazardous Materials (HazMat) Marathon

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Ready for something a little different? This Indiana CDL Hazardous Materials (HazMat) Marathon is a super-challenging study tool that contains a mix of all 191 questions that we have available for this IN 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”. It might take some time, but you can do this!

Real exam-style pitfalls you’ll practice:

Distractors
Trick Wording

Easy to follow and to learn.
It also helps I’m a fast learner, I took the test one day after studying the hazmat material and passed with ease. For those who can learn by making educated guesses and being told what the correct answer is after, this is a great source to attain endorsements.

I give driving-tests.org a 5 star.
They were more than helpful in getting me to pass my eldt class. In fact I passed their class and took the hazmat test at the dmv the next day and didn’t miss a single question! Also I went camping and wasn’t able to do my class the first time so they reinstated my week long course free of charge.
