Trailer Interchange Insurance
Last reviewed June 2026 by the Trucking Insurance Services team.
If you pull a trailer that belongs to someone else, your own truck policy probably does not cover it. Trailer interchange insurance fills that gap. It pays for physical damage to a non-owned trailer while it is in your possession under an interchange agreement, whether the trailer is hooked to your truck or dropped in a yard.
We are a trucking agency first, so we place this coverage every day for power-only, drop-and-hook, and intermodal operators. Here is what it covers, who needs it, and what it costs.

What trailer interchange insurance covers
Trailer interchange insurance pays for physical damage to a trailer or container that belongs to someone else while it is in your possession under a written interchange agreement. It covers the kinds of losses that happen on the road and in the yard, such as collision, fire, theft, and vandalism. It covers the equipment you pull, not the freight inside it. The load itself is covered by motor truck cargo insurance.
A useful way to think about it: the coverage follows the trailer the entire time it is in your care under the agreement. It does not stop the moment you unhook. That is the main thing that sets it apart from plain non-owned trailer coverage, which we explain below.
Why your liability and physical damage will not cover it
This is the part most owner-operators get wrong. Many assume their auto liability or their own physical damage already covers a trailer they pull. It does not. Liability pays for damage you cause to other people and their property in an accident. Your physical damage covers your truck and the trailers you own. A trailer that belongs to another company is someone else’s property, and the only thing that pays to repair it is trailer interchange coverage, or non-owned trailer physical damage.
That gap is exactly where drivers get stuck. You damage a trailer that is not yours, the owner sends you the repair bill, and your truck policy has nothing to respond with. Trailer interchange is the coverage built for that situation.
Trailer interchange vs non-owned trailer vs cargo
These three coverages get mixed up constantly because they all touch trailers and loads. Here is the difference in plain terms.
| Coverage | What it covers | When it applies |
|---|---|---|
| Trailer interchange | Physical damage to a non-owned trailer you pull | While it is in your possession under a written interchange agreement, attached or dropped and unattended |
| Non-owned trailer physical damage | Physical damage to a non-owned trailer | Only while the trailer is attached to your truck; no interchange agreement required |
| Motor truck cargo | The freight inside the trailer | While the load is in your care |
The key difference between the first two: trailer interchange keeps covering the trailer when you drop it at a yard, while non-owned trailer coverage stops the moment you unhook. If you run drop-and-hook, that gap matters. For a full breakdown, see trailer interchange vs non-owned trailer coverage.
Who needs trailer interchange insurance
- Power-only and drop-and-hook carriers. If you pull trailers you do not own under an agreement, this is the coverage that protects you.
- Intermodal and drayage haulers. Container haulers who lease a chassis from an equipment provider almost always need it. See intermodal and UIIA insurance.
- Amazon Relay and brokered loads. Many contracts require it. Amazon Relay requires a $50,000 trailer interchange limit.
How much it costs and what limit to carry
Trailer interchange is one of the more affordable coverages on a truck policy. It is usually added to your existing physical damage and liability coverage rather than bought on its own.
| Coverage | Typical cost |
|---|---|
| Trailer interchange | $1,000 to $3,500/yr ($85 to $290/mo) |
For the limit, carry an amount that matches both what your interchange agreement requires and what the trailer is actually worth. The average we see is $20,000 to $50,000. Specialty or high-value trailers, like reefers, tankers, and car haulers, can need $100,000 or more. This matters because a claim pays the lower of your limit or the trailer’s value, so a low limit on an expensive trailer leaves you owing the difference out of pocket.

The mistake that voids a claim: no signed agreement
The single most common way this coverage fails is paperwork. The coverage is triggered by the interchange agreement, so if a trailer is damaged and you cannot produce a signed interchange agreement, the claim can be denied. Keep a signed agreement on file for every trailer you pull. Most carriers require it in writing; a few will accept an oral agreement, but a written one is what actually protects you.
Frequently asked questions
What is trailer interchange insurance?
Trailer interchange insurance is physical damage coverage for a trailer you pull that belongs to someone else. It pays to repair or replace that trailer when it is damaged while in your possession under a written interchange agreement, whether the trailer is attached to your truck or dropped at a yard.
What does trailer interchange insurance cover?
It covers physical damage to the non-owned trailer, including collision, fire, theft, and vandalism, up to the limit you carry. It covers the trailer itself, not the freight inside it. The load is covered separately by motor truck cargo insurance.
What policy is trailer interchange part of?
It is added to your commercial truck policy, usually alongside your physical damage and liability coverage. You do not buy it as a stand-alone policy.
How much does trailer interchange insurance cost?
Trailer interchange typically runs $1,000 to $3,500 a year, or about $85 to $290 a month. Your rate depends on the limit you carry, your deductible, your driving record, and the value of the trailers you pull. The only way to get an exact number is to run a quote.
Do I still need it if I have cargo insurance?
Yes. Cargo insurance covers the freight, not the trailer. If you damage a trailer that belongs to someone else, cargo coverage will not pay to fix it. Trailer interchange is what covers the trailer.
What is the difference between trailer interchange and non-owned trailer coverage?
Trailer interchange covers a non-owned trailer the whole time it is in your possession under a written interchange agreement, even when it is dropped or parked. Non-owned trailer physical damage covers the trailer only while it is attached to your truck and does not require an agreement. For drop-and-hook work, that difference can decide whether a dropped-trailer claim gets paid. See our full comparison of trailer interchange vs non-owned trailer coverage.
