Any driver, regardless of the vehicle Class, who wants to haul hazardous materials, must add an “H” endorsement to their CDL.

The Montana hazmat test consists of 30 questions. To pass, you must correctly answer at least 24 questions (80%). The MT CDL hazmat test covers the information found in the Montana CDL Manual. Study the chapter covering hazardous materials to learn how to recognize, handle, and transport Hazmat, then take this practice test to prepare for your exam!
