Driving and Parking Rules — CDL Hazardous Materials Practice Test
This CDL Hazardous Materials Driving and Parking Rules practice set has 28 real questions based on the official handbook, each with an instant explanation. You need 80% on the real CDL Hazardous Materials knowledge test to pass.
What must you do when fueling a motor vehicle that contains hazardous materials?
📚 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.
