New York CDL Hazmat: Hazard Classes Test 2026

Nine classes sort everything a placarded truck can legally carry, and the New York CDL hazmat hazard classes test checks that you can keep them straight. Explosives, gases, flammable liquids, flammable solids, oxidizers and organic peroxides, poisons and infectious substances, radioactive material, corrosives, and the miscellaneous class each fail differently in a crash. The 2026 questions push you to match the risk to its number quickly.

New York hazmat drivers lean on this daily, because the class dictates the paperwork, the placard, the segregation rules, and the emergency response. Loading incompatible classes together is a favorite exam trap and a genuine road danger. Division numbers appear too, narrowing a broad class into a specific threat such as a flammable gas.

Keep the hazard class table from your New York CDL Manual open as you drill, and rely on that same manual for the exact count of questions on the New York hazardous materials endorsement exam.
