CDL Hazmat driving, parking and training study guide
The driving and parking rules in 49 CFR Part 397 apply to motor carriers, their supervisors and the people who operate or are in charge of a vehicle carrying hazardous materials that must be marked or placarded, and 49 CFR Part 172 Subpart H sets the training requirements for hazmat employees. This guide sets out what the rule text states on who Part 397 covers, attending and parking vehicles, fires, smoking, fueling, tires, the documents carried with Division 1.1, 1.2 or 1.3 (explosive) materials, the routing rules as they affect drivers, and hazmat training: who must be trained, what it covers, when it is due and what records are kept. Many rules apply only to explosives or only to Class 7 (radioactive) materials, so the exact words matter. The hazardous materials endorsement also needs a TSA security threat assessment and a State knowledge test; this guide covers neither, and goraedu does not issue endorsements. Your State may have its own requirements, so check them too. Every point links to the regulation and quotes its exact words.
Who Part 397 applies to
Part 397 applies to each motor carrier transporting hazardous materials by a motor vehicle that must be marked or placarded in accordance with 177.823.
“The rules in this part apply to each motor carrier engaged in the transportation of hazardous materials by a motor vehicle which must be marked or placarded in accordance with § 177.823 of this title”
