What is the primary document used in highway transport to outline cargo details?

The Bill of Lading is the primary document used in highway transport to outline cargo details. This document serves multiple functions: it acts as a receipt for the goods, a contract for the transportation of the goods, and a document of title, which means it can be transferred to others. It includes critical information such as the description of the cargo, the shipper's details, the consignee's information, and instructions for handling the goods.

While other documents, such as the Dangerous Cargo Manifest, Way Bill, and Air Bill, play significant roles in specific transport contexts, they do not serve the same comprehensive purpose for highway transport as the Bill of Lading. The Dangerous Cargo Manifest is more specific to hazardous materials and may not be used for all types of goods. The Way Bill is often used in trucking as well but does not provide the same level of detail about ownership and the transfer of title. The Air Bill is specific to air transport and is not applicable for highway transportation. Hence, the Bill of Lading is the most relevant and widely recognized document for detailing cargo in highway transport.
