Trip leasing and double brokering are distinct practices within the freight transportation industry, though both involve the use of another carrier's equipment, they differ in legality and intent. Trip leasing is a legal practice where a carrier temporarily leases another carrier's equipment for a specific trip, while double brokering is the illegal act of a broker tendering a shipment to another broker or carrier without the shipper's consent, often leading to financial and logistical issues.
