If a Division 2.3 (Poison Gas) or 6.1 (Poison) material might also be flammable, what should you do in an emergency?
📚 CDL Manual — Hazardous Materials (§9)
Questions are based on Section 9 (Hazardous Materials) of the official CDL manual (AAMVA model). 🔴 The HazMat (H) endorsement knowledge test is given in ENGLISH ONLY in every state — it is security-sensitive and, unlike the General Knowledge test, is not offered in other languages anywhere (federal rules bar interpreters). Our Chinese & Spanish are study aids to help you learn the English material. The H endorsement also requires a TSA Security Threat Assessment (fingerprint background check) in addition to passing this test.
