CMR, or Consignment Note for Road Transport, is a legal document used in the transportation of goods by road. It serves as a contract between the sender, carrier, and receiver of the goods, outlining the details of the shipment such as the type and quantity of goods, their origin and destination, and the terms of delivery. This document is crucial in ensuring the safe and efficient transport of goods, as it provides a record of the journey and acts as proof of delivery. CMRs are commonly used in international trade and are recognized by most countries as a standard document for road transport.
