MO 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 Missouri CDL Hazardous Materials (HazMat) Marathon is a massive practice test that contains a compilation of all 192 questions that we have available for this MO endorsement. If you give an incorrect 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. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Give it your best shot!

Definitely helpful and I recommend.
I was a little skeptical at first doing the ELDT hazmat online at first but it's better than doing the in person class also the 50 most common questions print out was good material as well good for future preparation. I passed the hazmat test with ease 100%
D
A thorough study aid.
The course for the hazmat was well laid out and had all the information needed to pass the test. I studied it for seven days, finished most of it the day before the test, and passed the price was reasonable. The material was spot-on, up-to-date, and accurate.
JK
Perfect program for ELDT requirements.
The Drivng-tests program for getting my hazmat endorsement was great. It was very thorough and covered everything I would need to know. The practice tests were extremely helpful. I passed the test at the registry easily. I can't recommend them enough
