UIIA Insurance Companies FAQ

The Uniform Intermodal Interchange & Facilities Access Agreement (UIIA) is a standardized legal contract used in the intermodal trucking and freight industry that governs the interchange of shipping containers, chassis, and equipment between motor carriers and intermodal equipment providers (IEPs). Read more

Any motor carrier or drayage company that picks up or returns intermodal containers or chassis at terminals must sign the UIIA with participating intermodal equipment providers. Read more here

The UIIA:

• Defines liability for loss or damage to intermodal equipment
• Standardizes terms across carriers and terminals
• Helps avoid costly disputes
• Ensures legal compliance in intermodal operations

This provides consistency and protects both carriers and equipment providers. Read more here

The UIIA typically covers:

Operational procedures

Interchange liability

Loss/damage responsibilities

Repair charges

Container/chassis usage rules

Indemnification requirements – Read more here

Yes. The UIIA is a standardized national agreement used across the United States. All carriers sign the same core terms, though individual IEPs can attach supplements for specific rules or policies. Read more here

To obtain and sign a UIIA:

Complete and execute the agreement as directed by the IEP.

Contact an intermodal equipment provider (IEP) such as a container/chassis lessor.

Submit required documents (MC number, insurance, authority). Read more here

Under the UIIA, carriers must carry minimum insurance to cover:

Loss/damage to containers, chassis, or equipment
Insurance must be maintained and cover carriers while equipment is in their control.

Interchange liability. Read more here

Interchange fees are charges assessed when equipment is damaged, lost, or exceeds free time on a container or chassis. These fees vary by provider and are detailed in the provider’s tariff or supplemental rules. Read more here

A UIIA remains valid indefinitely as long as the carrier maintains:

• Active operating authority
• Required insurance
• Good standing with the equipment provider

Termination occurs only if voluntarily canceled, by request of the provider, or if contractual requirements lapse. Read more here

Yes — intermodal equipment providers can update supplements or tariffs affecting usage rules, fees, and procedures. Carriers must comply with the current terms in effect at the time of interchange. Read more here

If intermodal equipment is damaged while under a carrier’s control:

Charges may include storage, chassis repairs, container refurbishment, or loss settlement.

The carrier is liable for repair or replacement costs, per the UIIA and provider tariff. Read more here

Owner‑operators operating under their own authority must sign UIIA agreements directly with intermodal providers if they perform interchange without a motor carrier’s UIIA. Read more here

No. Carriers must sign a UIIA with participating providers before picking up containers or chassis at terminals. Operating without it can lead to equipment denial or financial liability. Read more here

To update insurance:

Confirm acceptance and that records are updated before interchange

Contact your intermodal equipment provider

Provide updated proof of insurance (such as ACORD certificates or endorsements). Read more here

Truckers earn money by transporting containers and chassis between ports, rail yards, and warehouses for intermodal equipment providers (IEPs). Payment is usually per container moved, per mile, or per job, depending on the contract. Read more

Yes, owner-operators typically earn more per load because they take on responsibility for truck expenses, but they also cover fuel, maintenance, and insurance. Company drivers earn a salary or hourly wage without the overhead costs. Read more here

Higher-paying opportunities usually include:

Long-haul drayage moves between rail hubs and ports

Priority or expedited containers

Hazardous or specialized cargo (requires proper endorsements). Read more here

Earnings vary widely:

Owner-operators: $80,000–$150,000+/year depending on routes, number of trips, and efficiency

Company drivers: $50,000–$80,000/year. Read more here

Yes. Signing UIIA agreements with multiple intermodal equipment providers allows you to access more container loads, reduce downtime, and maximize revenue potential. Read more here.

Both payment models exist:

Rates depend on the IEP contract and region.

Per container: Fixed rate for each pickup/delivery

Per mile: Based on the distance traveled, often for long drayage runs. Read more here

Owner-operators must consider:

• Fuel and maintenance
• Insurance (including UIIA-required coverage)
• Chassis or container damage fees if at fault
• Administrative or dispatch fees

Managing these costs efficiently directly impacts net income. Read more here

Work with multiple UIIA-approved providers to get more loads

Minimize empty miles by coordinating return trips

Maintain a clean driving record to qualify for higher-paying loads

Keep your truck and equipment well-maintained to avoid penalties. Read more here

Working with multiple providers usually increases revenue opportunities, but requires careful scheduling and compliance with each provider’s rules. Full-time with one provider may offer stable income and benefits.

Start with local drayage routes to learn operations

Build a good reputation with equipment providers

Track your expenses vs income to optimize profit

Consider owner-operator leasing programs that provide access to high-volume container traffic

The form is part of the broader Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) program administered by the Intermodal Association of North America. Trucking companies participating in intermodal freight must follow UIIA requirements to legally interchange containers, chassis, and other equipment at ports and rail facilities across the United States.
