You can also try the online CDL hazmat endorsement test. Many motor vehicle departments offer free practice tests where you can check your knowledge and get a general idea of what the real test will look like, and which questions you might be asked.
This way, you will know how much you know and on what you need more practice before you spend your hard-earned bucks on the real test!
The practice test is a sampling of test questions where you need to answer correctly on 80% of the material in it! You should retake the test till you accomplish 100%, but 80 % correctness is the bare minimum.
Also, by being well prepared you will increase the chance of passing the hazardous materials test the first time around! So don’t duel on it and take few practice tests, you will be glad you did!
