Trailer Interchange vs Non-Owned Trailer Coverage
By Will Kremer, Truck Insurance Agent · Last updated June 30, 2026
If you pull trailers you do not own, two coverages can protect them: trailer interchange and non-owned trailer physical damage. They look almost the same on paper, but they apply differently, and picking the wrong one leaves a gap right where you need coverage.
We place both every day for power-only, drop-and-hook, and intermodal operators, so here is the plain-English difference and how to tell which one your operation needs.
|
The short answer Trailer interchange covers a non-owned trailer the whole time it is in your possession under a written interchange agreement, including when it is dropped or parked. Non-owned trailer physical damage covers the trailer only while it is attached to your truck and needs no agreement. Choose interchange if you drop trailers or a contract requires it; choose non-owned if you stay hooked and have no agreement. |

| Best for | Drop-and-hook, intermodal and drayage, contract-required work | Power-only that stays hooked, occasional non-owned use |
| Typical cost | $1,000 to $3,500/yr | 1.5% to 5% of the limit |
What trailer interchange coverage is
Trailer interchange insurance is for truckers who swap trailers with other carriers under a written interchange agreement. The agreement makes you responsible for the trailer while it is in your care, so the coverage follows that trailer the entire time you have it, whether it is hooked to your truck or dropped at a yard. That is the key feature: it does not stop when you unhook.
It is the standard choice for drop-and-hook freight, logistics networks that move trailers between companies, and intermodal or drayage operators who lease a chassis. If you haul containers out of ports and railyards under the UIIA, or you run loads that require it such as Amazon Relay, this is the coverage you need.
What non-owned trailer physical damage is
Non-owned trailer physical damage also covers a trailer you pull but do not own, but it applies only while that trailer is attached to your truck, and it does not require an interchange agreement. The moment you drop the trailer and walk away, the coverage stops. For carriers who stay hooked, that is a non-issue, which is why it is a common fit for power-only haulers.
The trap to avoid is the limit. Power-only haulers often pick up whatever trailer a broker hands them, and that trailer can be worth far more than the dry vans they usually pull. Because the coverage pays only up to your limit, set the limit to the most expensive trailer you might realistically pull.
Which one do you need?
It comes down to how you run and what your contracts require:
- Pick trailer interchange if you drop and leave trailers, you have a written interchange agreement, you haul intermodal containers, or a broker or terminal requires it.
- Pick non-owned trailer physical damage if you run power-only, stay hooked to the trailer, and have no interchange agreement.
- Not sure? If there is any chance you will drop a trailer and leave it, trailer interchange is the safer choice, because non-owned coverage would not respond to a dropped-trailer claim.
How much each one costs
Both are affordable add-ons to your truck policy. Trailer interchange is priced as a flat premium, while non-owned trailer physical damage is priced as a percentage of the limit you choose.
| Coverage | Typical cost |
|---|---|
| Trailer interchange | $1,000 to $3,500/yr; carry a $20,000 to $50,000 limit, or more for specialty trailers |
| Non-owned trailer PD | 1.5% to 5% of the limit; a $25,000 limit runs about $375 to $1,250/yr |
Some agreements set a required minimum. Amazon Relay, for example, requires a $50,000 trailer interchange limit. Rates are personalized, so the only way to know your number is to run a quote.
Frequently asked questions
What is the difference between trailer interchange and non-owned trailer coverage?
Both cover physical damage to a trailer you pull but do not own. Trailer interchange covers it the whole time it is in your possession under a written interchange agreement, including when it is dropped. Non-owned trailer physical damage covers it only while it is attached to your truck and needs no agreement.
Does non-owned trailer coverage cover a dropped trailer?
No. Non-owned trailer physical damage only covers the trailer while it is attached to your truck. If you drop a trailer and leave it, you need trailer interchange, which keeps covering the trailer after you unhook.
Do I need both?
Most operators need one or the other, not both. The right one depends on whether you drop trailers and whether your contracts require an interchange agreement. An agent can look at how you run and set you up with the coverage that fits.
Which one does Amazon Relay require?
Amazon Relay requires trailer interchange coverage with a minimum $50,000 limit, because you are pulling Amazon’s trailers under an interchange arrangement.
How much do they cost?
Trailer interchange typically runs $1,000 to $3,500 a year. Non-owned trailer physical damage is priced at about 1.5% to 5% of the limit you choose. Your exact rate depends on your record, equipment, and limit.
