What document must drivers carry when transporting metal coils?

When transporting metal coils, a bill of lading is a critical document that drivers must carry. This document serves as a legal contract between the shipper and the carrier, detailing the type, quantity, and destination of the cargo being transported. It provides proof of the ownership of the goods and outlines the responsibilities of all parties involved in the shipment. Having a bill of lading helps ensure compliance with shipping regulations and provides essential information in the event of a dispute or incident during transit.

While other documents like an insurance policy, vehicle registration, and driver's logbook are important in their own contexts, they do not specifically address the cargo itself or its transportation. The insurance policy protects against damages or losses, vehicle registration verifies the legal operation of the vehicle, and a driver’s logbook tracks hours of service. However, for the specific task of transporting metal coils, the bill of lading is the document that directly relates to the shipment and is required by regulations governing freight transport.
