Ready to put your new knowledge to the test? This Texas CDL Hazardous Materials (HazMat) Marathon is a monster of a practice test that contains a combination of all 194 questions that we have available for this TX endorsement.

Verified student reviews • Shared with permission

I went and took my test yesterday here at the DMV, and I passed both tests.
I studied for a week, and I went in yesterday, and I missed one question on the hazmat test, and I didn't miss any on the tanker test. A lot of the questions that you guys have—pretty much all of the questions that you guys have on the curriculum app—they were on the both tests. They may have worded a little different on a few of them, but it was pretty much easy to comprehend
