Trailer Interchange Insurance for Owner Operators
Trailer interchange insurance covers physical damage to a trailer you don't own but are pulling under a written interchange agreement. Your physical damage policy covers the trailers on your title; interchange handles everyone else's. It's required any time you operate under a true interchange agreement with another motor carrier.
What Trailer Interchange Insurance Covers
- Collision damage to a non-owned trailer in your possession under a written interchange agreement
- Comprehensive losses on the interchanged trailer — fire, theft, vandalism, and weather
- Damage that occurs while the trailer is hooked to your truck or while it is dropped at a yard or dock
- Coverage up to your stated interchange limit, regardless of which trailer in the rotation is in your possession
- Towing and recovery of the non-owned trailer after a covered loss, up to a sub-limit on most forms
- Legal defense if the trailer's owner sues you for damage under the interchange agreement

Trailer interchange is priced as a percentage of the interchange limit — the maximum value of any non-owned trailer you would pull. The range is typically 1.5–3% of the limit per year.
Who Needs Trailer Interchange Insurance?
If you operate under your own authority and routinely pull a trailer that belongs to a shipper, broker, or another motor carrier under an interchange agreement, you need this. Power-only operations live and die on trailer interchange — every load is a non-owned trailer. Own authority operators running power-only or pulling drop-and-hook freight for a single shipper almost always require interchange. Leased-on operators typically don't need it — the carrier they're leased to provides the trailer and covers it under the carrier's own policy.
Common Exclusions
- Most policies exclude damage to the freight inside the trailer — cargo coverage is a separate policy
- Typical exclusions include damage to trailers you own, lease long-term, or have on your title — those belong on physical damage
- Most policies exclude losses without a written interchange agreement on file at the time of loss
- Typical exclusions include mechanical breakdown, wear and tear, and damage from improper loading by a shipper
- Most policies exclude refrigeration unit failure on a reefer trailer — that needs a reefer breakdown endorsement on cargo
- Specific exclusions vary by carrier — review the policy form and confirm what trailer types are listed before you accept a load
Exclusions vary by carrier — always review your declarations and exclusions schedule before binding.
Frequently Asked Questions
-
Trailer interchange covers trailers you pull under a written interchange agreement, usually with another motor carrier under MC-to-MC interchange. Non-owned trailer coverage is broader: it covers any trailer you do not own, with or without a formal interchange agreement. If you do power-only freight for brokers and shippers without interchange paperwork, you typically need non-owned trailer, not interchange.
-
Set the limit to the highest value of any trailer you might possess. Standard dry vans and flatbeds usually sit between $25,000 and $40,000. Reefers run $50,000 to $80,000. Specialized equipment — tankers, lowboys, RGNs — can hit $100,000+. If your limit is too low, you are personally on the hook for the difference.
-
No. Interchange only covers the trailer itself (the metal box). The freight inside is covered by motor truck cargo, which is a completely separate policy with its own limit and deductible. Brokers and shippers will typically require both.
-
FMCSA doesn't require trailer interchange. The requirement comes from the interchange agreement itself — most written interchange contracts make the receiving carrier liable for damage to the trailer while in possession. Without coverage, that liability lands on you personally.
-
Most interchange policies cover the trailer "in your possession," which includes drop time at your yard, a customer's yard, or a truck stop, not just while you're hooked up and rolling. Read the policy form for the exact possession definition; some carriers limit coverage to time hitched to your truck only.
-
No, physical damage only extends to listed trailers. The main physical damage policy is built for the trailers on your schedule. If you're routinely pulling someone else's trailer, don't assume your physical damage will respond — buy interchange or non-owned trailer separately.
-
Interchange covers physical damage to the trailer. Mechanical failure of the reefer unit causing cargo loss is a different exposure, addressed by a reefer breakdown endorsement on your cargo policy. The two policies cover two different losses on the same trailer.
