Hazardous Materials Tests - Practice Mode

In Practice Mode, you receive instant correct answers after every question AND a CDL reference. This points you to the exact location in the official state CDL manual to aid your study. Choose a test to get started below.

Hazardous Materials Tests - Exam Mode

Each practice test is timed and you get your grade and results only after you've finished each test. This is very much like the official state CDL written exams! Choose a test to get started below.

You must have a CDL with a Hazmat (Hazardous Materials) Endorsement before you drive any size vehicle that is used in the transport of any material that requires hazardous material placarding or any quantity of a material listed as a select agent or toxin in 42 CFR 93.

If you're just getting started, we recommend first getting your state CDL manual, then start with the Classic Mode of each CDL Hazardous Materials practice test and you'll have a good idea where you stand. Next, navigate to the Practice Mode for more intense preparation. Finally, finish up in Exam Mode when you think you're ready.
