In an interchange, another carrier or an equipment provider hands you its trailer to continue a move, and the written agreement sets out your responsibility for it while it’s in your hands. Trailer interchange coverage pays for physical damage to that equipment, such as collision, fire or theft, when you’re liable for it. It’s most common in intermodal drayage, where most equipment providers under the UIIA require it and each sets its own limits and deductibles.
What interchange is
Federal leasing rules define interchange as one motor carrier receiving equipment from another, at a point both are authorized to serve, to continue a through movement. Authorized for-hire carriers can interchange equipment only under a written contract, lease or other arrangement that describes the equipment, the points of interchange, how it will be used and the compensation, signed by both sides.
Intermodal work has its own version. FMCSA’s rules define an intermodal equipment interchange agreement as the Uniform Intermodal Interchange and Facilities Access Agreement, or another written document, whose main purpose is to set the responsibilities and liabilities of the equipment provider and the motor carrier for the equipment being interchanged.
What the coverage pays for
Trailer interchange is physical damage coverage for equipment you don’t own. Oregon’s state risk management office describes it as coverage for the legal liability of truckers for loss or damage to non-owned trailers and equipment in their possession under a written trailer or equipment interchange agreement.
The administrator of the intermodal industry’s interchange agreement spells out what its equipment providers expect: physical damage to non-owned containers, chassis or trailers while in the motor carrier’s care, custody or control, covering comprehensive and collision as well as fire and theft.
Two other policies don’t do this job. Physical damage coverage on your own trucks and trailers is written for the equipment you own and list on the policy. Motor truck cargo covers the freight inside, not the box it rides in. How cargo coverage works.
Who needs it
- Intermodal drayage carriers. Most equipment providers under the UIIA require some type of trailer interchange coverage before they will interchange containers and chassis.
- Carriers in trailer swaps or relays with other carriers under written interchange agreements.
- Carriers whose contracts make them responsible for a customer’s or another carrier’s trailer while it’s in their hands. The agreement sets what you owe, and the coverage should be sized to it.
If you pull someone else’s trailer without a written interchange agreement, as on some power-only loads, ask how your policy treats that before you rely on it, because interchange coverage is defined around a written agreement.
Limits, deductibles and what to check
No federal rule requires trailer interchange coverage or sets a minimum for it. In intermodal work, each equipment provider sets its own limits and deductibles, so the limit you need is driven by the most demanding provider you work with. The UIIA itself also requires auto liability with a $1 million combined single limit and general liability of $1 million per occurrence, and equipment providers you work with must be listed as additional insureds on your auto liability.
- The limit per unit, measured against the most valuable trailer, container or chassis you might pull.
- Covered causes of loss. Interchange coverage for UIIA work must include comprehensive and collision, plus fire and theft.
- The deductible against what each provider allows.
- The agreement itself. Your responsibility under an interchange contract can reach beyond physical damage, so read what you sign.
Paperwork before you hook up
Under the federal leasing rules, unless a copy of the interchange agreement rides with the equipment, a carrier operating a power unit in interchange service must carry a signed statement identifying the equipment, the point of interchange, the date and time it took responsibility, and how the equipment will be used. That statement isn’t required when only trailers or semitrailers are interchanged.
Document the equipment’s condition when you take it and when you return it. Time-stamped photos at pickup and drop give you evidence of when any damage happened. How I put together a trucking program.
Common questions
Does my cargo policy cover a damaged trailer I’m pulling?
No. Cargo coverage is for the freight. Damage to a trailer you don’t own is the job of trailer interchange or similar coverage for non-owned equipment.
Is trailer interchange insurance required by law?
No federal rule requires it. It’s required by contract, most often by intermodal equipment providers under the UIIA and by carriers you exchange trailers with.
How much trailer interchange coverage do I need?
Enough to meet the highest limit any equipment provider or contract partner requires, and enough to replace the most valuable unit you pull. Each UIIA provider sets its own limits and deductibles.
Does trailer interchange cover my own trailer?
No. It is for equipment you don’t own. Your own trailers are protected by physical damage coverage on your policy.
Who has to be named on my certificates for intermodal work?
UIIA equipment providers you work with must be listed as additional insureds on your auto liability, and some also require it on general liability. Check each provider’s requirements.
