For highway hazmat shipments, which document is typically kept in the cab to describe the material?

• A. Emergency kit
• B. Driver's log
• C. Safety data sheet
• D. Shipping papers

Answer: (D)

The key idea is understanding what paperwork is required to describe a hazmat load during transport. The document kept in the cab is the shipping papers. These papers are the primary source of identifying information for the load—they list the material’s proper shipping name, hazard class, identification number, packing group, quantity, and the shipper and consignee, along with emergency response details. Having them in the cab ensures the driver can quickly reference the material being transported and provide the necessary information to responders or inspectors if needed.

The emergency kit is for handling incidents, not for describing the material. The driver’s log tracks hours of service, not the hazardous material’s identity. The safety data sheet contains safety and handling details, but it’s not the standard document carried in the cab to describe the shipment during transport; the shipping papers are the required, readily accessible reference for the material while en route.
