Quick Answer: UIIA insurance is the coverage package a motor carrier needs to move equipment under the Uniform Intermodal Interchange and Facilities Access Agreement. It requires $1,000,000 auto liability, $1,000,000/$2,000,000 general liability, a UIIE-1 endorsement, and trailer interchange coverage together. Miss any piece and ports will not release equipment.
Key Takeaways
- UIIA insurance is not a single policy. It is auto liability, general liability, cargo, and trailer interchange coverage verified together.
- The UIIE-1 endorsement fails on exact contract wording far more often than on price. A cheap quote and a working endorsement are 2 different questions.
- Progressive began limiting how it writes UIIA coverage on January 22, 2026. Hold-harmless language, not underwriting appetite, is the actual sticking point.
- Getting approved does not get your truck through the gate. TWIC, RFID, and a steamship line interchange agreement still stand between you and the container.
- A photo of the chassis at pickup is the cheapest insurance you will ever buy against a trailer interchange claim for damage you did not cause.
We hear the same story from owner-operators on repeat. UIIA approval arrives, then a cancellation email lands within hours.
Having placed this coverage for over a decade, we trace that failure to a single clause. It is covered below, alongside the parts of drayage access insurance alone never solves.
UIIA Insurance, Defined
UIIA insurance is the proof of coverage a motor carrier files to join the Uniform Intermodal Interchange and Facilities Access Agreement, managed by the Intermodal Association of North America (IANA).
This single filing replaces what used to be a separate contract with every port, railroad, and leasing company a carrier touched. A single ACORD 22 certificate now covers every participating Equipment Provider (EP).
A carrier without active UIIA status cannot pick up or drop equipment at any participating port or rail yard, regardless of safety record.
UIIA Insurance Coverage Requirements
UIIA insurance is not 1 policy but 4, layered together. Equipment Providers can push any of these limits higher through Form 5B, so treat this table as the floor, not the ceiling.
| Coverage | Minimum Limit | Key Detail |
|---|---|---|
| Auto Liability | $1,000,000 CSL | Must read “Any Auto” or “Scheduled and Hired,” never “Scheduled Only” |
| General Liability | $1,000,000/occurrence, $2,000,000 aggregate | No self-insured retention permitted |
| Motor Truck Cargo | $100,000 minimum | Some EPs require $250,000; $1,000 deductible standard |
| Trailer Interchange | $20,000-$35,000 per unit | Must include comprehensive, collision, fire, and theft |
The UIIE-1 Endorsement Fails on Wording, Not Price
The UIIE-1 endorsement is a hold-harmless clause attached to your auto liability policy. EPs accept UIIE-1, CA23-17, or TE23-17B, but only in current-version language.
Here is the detail most guides skip entirely. Rejection almost never traces back to the liability limit.
It traces back to whether the hold-harmless wording matches what the EP’s agreement requires, word for word.
We have watched a carrier quote a genuinely competitive rate and still fail this check. Price and endorsement compliance get underwritten as 2 separate questions.
Additional Insured Status for UIIA Has to Travel With Every EP
Every EP your truck does business with needs additional insured for UIIA status, not just the first port you clear. This is the single gap we catch most during a policy review.
A carrier adds 1 rail yard as additional insured, then gets flagged at a second yard under the same UIIA account.
The Carriers Still Writing UIIA Insurance in 2026
Carrier appetite shifted hard in early 2026. Comparing UIIA insurance carriers side by side is the question we field most from owner-operators shopping renewals.
Inside Progressive’s January 2026 Pullback
Effective January 22, 2026, Progressive moved to writing UIIA coverage only on a limited basis, confirmed in IANA’s own agent reference packet. The reason traces to specific contract language, not a blanket retreat from trucking risk.
That hold-harmless requirement asks the insurer to cover owner-operators the instant they are dispatched, even before the file is updated. Retail carriers built around individually-scheduled auto policies were never underwritten for that kind of standing exposure.
So Progressive restricted the endorsement rather than keep offering it broadly.
Where the Endorsement Still Gets Written
Knights Specialty Insurance, Trisura Specialty, and Accredited Specialty are among the UIIA insurance providers that still confirm the UIIE-1 or CA23-17 endorsement without restriction.
These carriers sit in the same wholesale and E&S market already built to handle harder-to-place trucking risk like auto haulers and tank trucks.
Before binding with any of them, confirm these in writing:
- The exact endorsement version, since only current-version language qualifies
- Whether Hired Autos coverage is included, since some carriers quietly exclude it
- The carrier’s NAIC number and current A.M. Best rating, documented for the ACORD 22 filing
New Trucking Insurance vs. Adding the UIIA Endorsement
Whether you need to purchase new trucking insurance to satisfy UIIA depends entirely on how your current policy is worded.
If your primary truck liability policy already reads “Any Auto” or “Scheduled and Hired,” your insurer may only need to attach the UIIE-1 endorsement and trailer interchange coverage.
| Auto Liability Policy Wording | Qualifies for UIIA? |
|---|---|
| Any Auto | Yes |
| Scheduled and Hired | Yes |
| All Owned | No |
| Scheduled Only | No |
When Your Current Policy Does Not Qualify
Wording, not the dollar amount, is what forces a carrier switch. A policy written as “All Owned” or “Scheduled Only” fails regardless of how high the limit sits.
The Broker SCAC Workaround Only Buys Time
Some carriers bridge that gap by running loads temporarily under a broker’s SCAC code and insurance. It works only because the move is technically performed under the broker’s own interchange agreement.
That bridge holds for a handful of loads and ends whenever the broker says so. It never substitutes for an active UIIA account.
UIIA Insurance Gets You Approved, Not Through the Gate
Insurance clears your file. It does not clear the terminal gate, a distinction that trips up more new carriers than the insurance requirements themselves.
Confirm each of these before promising a customer a drayage pickup date:
- An active TWIC card for the driver
- An RFID transponder registered to that specific truck
- A separate interchange agreement with the steamship line (SSL), layered on top of your UIIA account, for container pickups
Even 1 missing item stops the truck at the gate, regardless of how clean the UIIA policy on file looks.
Choosing a UIIA Insurance Agent
A UIIA insurance agent who has personally filed ACORD 22 certificates catches problems a generalist working off a rate sheet will not.
How a Specialist Vets a Carrier Before Binding
Before recommending a carrier, a specialist confirms that carrier is actively issuing the UIIE-1 endorsement right now, not that its guidelines merely allow it. That single verification call prevents the cancellation whiplash described above.
Contact Alvix and we take it further:
- Confirm live UIIA participation status with IANA directly
- Verify Hired and Non-Owned Auto coverage is actually included
- List every EP you work with as additional insured
- Time renewal so effective dates match with zero lapse
The Underwriting File a UIIA Carrier Actually Wants
Underwriters ask for specific documents, not a general business summary.
Have these ready before the first call:
- MC number and DOT number
- Current FMCSA safety profile
- 4 quarters of IFTA reports
- Loss run history
Walking in ready shaves days off approval, not weeks.
Staying UIIA Compliant After Approval
Getting approved once is the easy part. Staying compliant through renewal is where most carriers slip, usually over a missing field rather than a missing coverage.
1. NAIC Numbers and A.M. Best Ratings on the ACORD 22
Since June 3, 2024, IANA has required agents to list each policy’s NAIC number, A.M. Best rating, and rating effective date directly on the ACORD 22.
Clean applications still bounce back over a missing rating field more often than over any actual coverage gap.
2. Why Chassis Photos Matter at Claims Time
Pool chassis get reused in rougher shape than most claims guidance admits. A bad-order tag tends to get pulled off by the next driver long before the equipment gets fixed.
Photograph these 4 points every time you hook up:
- Tires and wheels for existing wear or damage
- Lights and reflectors
- Brake lines and air hoses
- The kingpin and locking mechanism
That habit separates a clean trailer interchange claim from a dispute over damage that predates your truck.
3. Cancellation Notice and Renewal Timing
UIIA policies must carry a 30-day advance cancellation notice, or 10 days for non-payment specifically. Submit renewal paperwork ahead of your expiration date.
Even a 1-day gap between the old and new policy freezes your account until the paperwork clears. Per diem on held equipment does not pause while that clears.
