Michigan CDL Hazmat: Hazard Classes Test 2026

Sorting a load into the right category is the whole point of the Michigan CDL hazmat hazard classes test. The federal system runs from Class 1 explosives through Class 9 miscellaneous materials, and knowing which is which drives your placarding, segregation, and paperwork decisions on every 2026 hazmat run.

This practice test walks through the nine hazard classes and the divisions inside them, from flammable liquids and gases to oxidizers, poisons, corrosives, and radioactive materials. You will match materials to their class, recognize how incompatible loads must be kept apart, and see why the hazard class controls so much of what a Michigan CDL hazmat driver does. The Michigan CDL Manual lays out the class definitions you are being quizzed on here.

The HazMat endorsement question count is set by the Michigan Secretary of State and can shift, so confirm the exact number in your Michigan CDL Manual rather than guessing. Drill these hazard classes until naming the category for any material is second nature.
