About the Kentucky CDL hazard classes test
Knowing your nine hazard classes is non-negotiable for the H endorsement, and this Kentucky hazmat hazard classes test drills them until the labels stick. It is aimed at CDL candidates working toward hazardous materials authority in 2026.
The hazmat hazard classes test walks through explosives, gases, flammable liquids, flammable solids, oxidizers, poisons, radioactive material, corrosives, and the miscellaneous category. Each item asks you to match a material to its class and recall the handling cautions the Kentucky Commercial Driver License Manual attaches to it.
The count of questions on the hazmat exam is not uniform nationwide, so verify it against your Kentucky CDL Manual rather than a forum post. Getting the classes right feeds directly into placarding and segregation decisions later, so run this hazard classes drill repeatedly until you can name every class on sight before your Kentucky CDL endorsement exam.
Every question traces back to the Kentucky CDL Manual - skim the right-of-way and signs chapters before your retake.
