SD CDL Hazardous Materials (HazMat) Marathon

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

Fasten your seat belt for one last wild ride of studying! This South Dakota CDL Hazardous Materials (HazMat) Marathon is a gargantuan study tool that contains a mixture of all 192 questions that we have available for this SD 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:

Trick Wording

Really great program.
You can work at your own pace and take up to a week a month or a year whichever is best for you. In my case I had two days before I took my hazmat/tankers endorsement test so I was pressed for time I went through the whole training course within about 12hrs. Once you complete the program I guarantee you will be ready for your dmv test. I missed one question on my tankers test and passed my hazmat test with 100%. I recommend this course for anyone looking to acquire their hazmat or tankers endorsement.

A great study system.
Passed my combination, passenger and hazmat endorsements easily because of the excellent prep classes provided. Multiple practice exams (with hints!) and a full text at the end for each endorsement. It really is a good system.

Studied for 2 days and aced the test.
When you have to renew your hazmat endorsement, you don't have time to risk failing the DMV test. An appointment must be made to take each test. I wanted to be absolutely sure that I passed the test with the one appointment that was available in October. I did the practice tests and study materials. I learned more from studying the materials and taking the practice tests than I ever learned from reading the DMV Hazmat book. Mission accomplished.
