In plain language: Trailer interchange insurance pays for damage to a trailer your trucking company pulls but does not own, when a written agreement makes you responsible for it. The owner gets paid, and you avoid a large bill.
Technical definition: Trailer interchange insurance (CA 23 98) covers the insured's legal liability for damage to trailers of others held under a written trailer interchange agreement. IRMI notes it is written on truckers and motor carrier forms and added by endorsement to the business auto policy.

Key Takeaways
- Trailer interchange coverage pays for damage to another company's trailer while a carrier holds it under a signed interchange agreement.
- Equipment providers often require the coverage before a carrier pulls their trailers, so CSRs see it on contracts and certificates.
- The coverage applies only when a written agreement exists, so carriers hauling without one need non-owned trailer coverage instead.
- Agencies should match the coverage limit to the costliest unit pulled, such as high-cube reefers or specialty trailers.
What Is Trailer Interchange Insurance in Insurance?
Trailer interchange insurance is coverage for trailers a trucking company does not own but has agreed to care for. Carriers often trade trailers in different locations to keep freight moving. Under a trailer interchange agreement, the carrier in possession is responsible for any damage, whether or not the trailer is hooked to its tractor, according to IRMI.
Under 49 CFR 376.31, authorized carriers that interchange equipment need a signed written agreement describing the equipment, the interchange points, its use and the compensation.
Picture a carrier pulling a railroad's dry vans from rail terminals to customer docks. If a van is crushed in a yard collision, the policy pays the railroad for repair or replacement costs, minus the deductible. Freight forwarders that never take possession of a trailer usually have no interchange exposure.
How Does Trailer Interchange Insurance Work?
- Signing the trailer interchange agreement. A signed agreement shifts responsibility to the carrier that takes possession.
- Picking up the trailer. Interchange receipts, EDI records, and photos log its condition and pickup time.
- Suffering a loss. Collision, fire and explosion, theft or weather-related damage harms the unit while the carrier has it.
- Filing the claim. Carriers report the loss with a police report or incident report, a driver statement and tow invoices.
- Settling with the owner. After authorizing repairs, the insurer pays the owner for repairs, actual cash value, or a total loss, within the limit.
Claim Examples Involving Trailer Interchange Insurance
What does trailer interchange insurance cover after a yard backing accident?
A drayage company hauls a railroad's reefers under a signed agreement. One driver backs a reefer into a light pole, and the policy pays for body repairs. Damage from mechanical breakdown or a reefer breakdown would not be paid.
What is trailer interchange coverage worth when a dropped trailer is stolen?
A carrier running small fleets leaves an empty dry van from a drop-and-hook load at a customer lot. Thieves take it overnight. The insurer then pays the owner the trailer value.
Trailer Interchange Insurance vs. Non-Owned Trailer Physical Damage: What Is the Difference?
Trailer interchange vs. non-owned trailer coverage comes down to paperwork. The first applies when a written agreement shifts liability to the carrier. Non-owned trailer coverage protects trailers pulled without one, such as a trailer rental or a power-only load.
| Comparison area | Trailer Interchange | Non-Owned Trailer |
|---|---|---|
| Primary use case | Units held under an interchange agreement | Units pulled with no agreement |
| Coverage/concept type | Legal liability for others' trailers | Direct damage to non-owned units |
| Typical exclusions | Wear and tear, breakdown, cargo | Same |
| Who is most affected by errors? | Intermodal and drayage carriers | Owner-operators |
| Common mistakes | Limit below unit value | Assuming interchange coverage applies |
What Are the Most Common Mistakes With Trailer Interchange Insurance?
- Confusing cargo with trailer. A motor truck cargo policy covers freight, while trailer interchange insurance coverage protects the box.
- Setting a low limit. Trailer pools often require higher limits, so the carrier pays the gap.
- Skipping the paperwork. Without a written interchange agreement, the claim may fall outside the coverage, leaving no claims support.
- Missing certificate details. A certificate of insurance missing the additional insured or loss payee can block facility access or load tenders.
- Ignoring rating facts. Trailer interchange insurance costs depend on cost drivers like garaging location, operating radius, loss history, and security protocols, so wrong answers skew the annual premium and create E&O exposure.
