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.
