Which documents verify transport compliance for hazmat shipments in intermodal moves?

• A. Only ERI.
• B. Shipping papers, ERI, required placards/labels, and any required security documents; the HazMat endorsement remains necessary.
• C. Only shipping papers.
• D. A driver's license and passport.

Answer: (B)

When moving hazmats across multiple modes, you prove compliance by carrying the full set of required documents: shipping papers that identify the hazardous material and its details, Emergency Response Information (ERI) for responders in an incident, the required placards or labels that warn and identify the hazards, and any security documents that are mandated for that shipment. The HazMat endorsement on your CDL is still required to handle and transport hazmat loads, but it isn’t a substitute for these documents. Relying on only one type of document isn’t enough: shipping papers alone don’t provide emergency guidance, ERI alone doesn’t meet labeling or security requirements, and a license or passport doesn’t document the specific regulatory protections and instructions needed for hazmat transport.
