Carriers must give each driver transporting Class 1.1 or 1.2 explosives a copy of FMCSR Part 397.

Answer: A — A copy of FMCSR Part 397

Providing a copy of FMCSR Part 397 to each driver handling explosives ensures they have the current legal rules they must follow when transporting hazardous materials. Part 397 covers the general requirements, responsibilities, and regulations that govern hazmat shipments, so having a readily accessible copy helps the driver reference the exact rules on the job and stay compliant. The other items don’t serve this regulatory purpose: a safety data sheet describes the hazards and safety procedures for a specific material, not the rules for transporting hazmat; a route map helps with planning but isn’t a regulatory document; a shipping label identifies the load but isn’t the regulatory text drivers need to reference.
