Trailer Interchange Insurance: Pulling a Trailer Not Yours

Have you ever pulled a trailer that belongs to someone else? Maybe it was a broker's trailer, a shipper's trailer or one from a leasing company. If it gets damaged while it is hooked to your truck, who pays? That is the question trailer interchange insurance tries to answer.

Trailer interchange insurance in plain words

Trailer interchange is a kind of physical damage coverage for a trailer you do not own. It applies when you pull that trailer under a written interchange agreement. Your regular physical damage coverage protects the equipment you own. Trailer interchange is meant for equipment you borrow. It is usually added to a policy as its own coverage, so it may not be there unless you ask for it.

Think of it like renting a car. The rental car is not yours, but you are still responsible for it while you drive it. Trailer interchange helps with that kind of responsibility for a trailer.

What a written interchange agreement is

A written interchange agreement is a signed paper between you and the owner of the trailer. It says you will take care of the trailer while it is with you. It also spells out who pays if something is damaged.

This paper matters a lot. Insurance sources say a signed, valid agreement is needed, and that having no agreement can lead to a denied claim. So do not hook up first and sort out the paper later.

Read the agreement slowly before you sign. Look for these things:

• Who owns the trailer.
• When your responsibility starts and when it ends.
• How much you may owe if the trailer is damaged.
• Any rules about how you must return the trailer.

If a line confuses you, ask before you sign. It is much easier to ask a question today than to argue about it after a loss.

What trailer interchange usually covers

This coverage usually helps pay for physical damage to the non-owned trailer from things like a collision, fire, theft, explosion or vandalism. In some operations it can also apply to chassis or containers while they are in your care. Every insurer writes its forms a little differently, so read yours and ask what your limit and deductible are. A deductible is the part you pay first before the insurance pays.

What it does not cover

Trailer interchange has limits. Here is what it usually leaves out:

• The cargo inside. Trailer interchange covers the trailer, not the freight. Cargo needs its own motor truck cargo coverage. You can read more in our cargo insurance basics article.
• Reefer unit failure and spoiled loads. If a refrigeration unit breaks and the load spoils, that takes a cargo policy with a reefer breakdown add-on, not trailer interchange.
• Wear and tear. Old parts, tires that fail from age and slow damage over time are usually not covered.
• Damage you cause to other people. That is what your auto liability coverage is for. Our guide on truck insurance coverage explained shows how the pieces fit together.

Mistakes to avoid when you pull non-owned trailers

• Hooking up before you sign. No paper can mean no coverage.
• Assuming your regular physical damage covers borrowed trailers. It may not. Ask your agent.
• Forgetting the cargo. A covered trailer with an uncovered load is still a big risk.
• Skipping photos at pickup. Take pictures of all sides of the trailer, the tires, the doors and the landing gear when you pick it up. If there is a claim later, photos help show what damage was already there.
• Not telling your agent. If you start pulling non-owned trailers often, your policy should match what you really do.

Common questions

Does trailer interchange cover the cargo inside the trailer? No. Trailer interchange covers physical damage to the trailer. The freight inside needs motor truck cargo coverage.

Do I need trailer interchange if I only pull my own trailer? Usually not. It is meant for trailers you do not own. If you pull only your own equipment, your regular physical damage coverage is the one to look at.

Why does the written interchange agreement matter so much? The agreement shows who is responsible for the trailer and when. Insurers look at it when a claim comes in, so a missing or unsigned agreement can cause big problems.
