When you pull a trailer owned by a shipper, intermodal company or another carrier under a written trailer interchange agreement, you're usually responsible for damage to it. Your own physical damage coverage doesn't extend to trailers you don't own — trailer interchange coverage does.

Interchange vs. non-owned trailer
- Trailer interchange applies when there's a written interchange agreement (common with intermodal and drop-and-hook freight).
- Non-owned trailer physical damage applies to trailers you borrow or use without a formal interchange agreement.
- Set the limit to the value of the most expensive trailer you'll pull — reefers can be worth far more than dry vans.

Do I need trailer interchange if I own my trailer?
No — insure your own trailer under physical damage. Interchange is only for trailers owned by others.
