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
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
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.
What Trailer Interchange Insurance Costs
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.
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.
-
Usually no, or only up to a small sub-limit (often $1,000 to $5,000). 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.
