Trailer Interchange
Trailer interchange coverage is discussed when a carrier pulls a trailer owned by another party under a written interchange agreement.
Plain-English summary
The coverage conversation should focus on who owns the trailer, who has custody, what agreement applies, and whether physical damage to the non-owned trailer is covered while in the carrier's control.
