Which of the following forms is designed to insure a single shipment of goods?

The Trip Transit Policy is specifically designed to cover the risks associated with a single shipment of goods during its transportation. This policy is suitable for businesses or individuals who send goods on a single journey and want insurance protection against potential losses or damages that could occur while the goods are in transit.

It typically covers a fixed period, usually aligning with the duration of the shipment, and protects against specific risks such as theft, loss, or damage arising during the transportation process. This makes it an ideal choice for one-off shipments rather than ongoing or multiple shipments.

In contrast, the other options serve different purposes. The Motor Truck Cargo Owners Form generally insures the cargo of a business that owns and operates trucks, providing coverage for multiple shipments over time rather than a single event. The Bailee's Customers Policy is intended for situations where a bailee (a person or entity temporarily holding someone else's property) is responsible for the property of others, and it covers the goods while in the bailee's custody, not strictly limited to a single shipment. Meanwhile, the Transportation Floater covers goods in transit but is broader and used for multiple shipments rather than isolated ones.

Therefore, the Trip Transit Policy is the most appropriate choice for insuring a single shipment of goods.
