Start Hazardous Materials CDL Test Practice in our original Classic Mode Now!
These Hazardous Materials tests are in Classic Mode. Retake all tests as needed. To prepare for the official CDL DMV exams, we recommend taking the following steps:
- Download your state CDL manual and open up it up in one tab of your browser. Read it over, but DON'T try to memorize it!
- In another tab, open up the first of our CDL practice tests in Classic Mode. See how well you do, but try not to stress out about any mistakes at this point.
- Quickly move into Practice Mode for more intense preparation.
- For more information, see How to Pass the Official State CDL Exams.
