LST Insurance, based in Dalton, Georgia, specializes in trucking and commercial insurance. When a commercial carrier operates a trailer it does not own — moving it under a written trailer interchange agreement — that trailer is exposed during every mile of transit and every hour it sits on a drop lot. Trailer interchange insurance is the policy that responds when something goes wrong with that trailer. Without it, a carrier that returns a totaled chassis faces a six-figure repair or replacement claim with no policy to cover it.
This guide covers trailer interchange insurance from the ground up: what it covers, who needs it, how it differs from non-owned trailer coverage, what carriers can expect to pay in 2026, and how to structure a program that closes the gap — not just meets the minimum requirement in the interchange agreement. For carriers who haul through any of the eight states LST serves, see the trucking and commercial transportation insurance overview for the full coverage picture.
What Is a Trailer Interchange Agreement?
A trailer interchange agreement is a written contract between two parties — typically two motor carriers, or a motor carrier and a terminal operator — that transfers temporary custody and care of a trailer from one party to another. The carrier taking possession agrees to assume financial responsibility for any damage to the trailer while it is in their possession.
Trailer interchange agreements are most common in four settings:
- Port drayage operations, where port chassis pools owned by leasing companies or ocean carriers are used by drayage carriers to move containers out of marine terminals
- Intermodal operations, where rail carriers hand off equipment to motor carriers for the final-mile segment
- Hub-and-spoke distribution networks, where trailers drop and are picked up by other carriers in a coordinated rotation
- Less-than-truckload (LTL) freight, where trailers move between terminals under multi-carrier interchange arrangements
Under 49 CFR Part 376, regulated interchange arrangements between motor carriers must be in writing, signed by both parties, and must clearly identify the responsible party during each phase of the movement. That written agreement is what triggers the trailer interchange insurance requirement — and what distinguishes this coverage from non-owned trailer coverage.
What Does Trailer Interchange Insurance Cover?
Trailer interchange insurance provides physical damage coverage for a non-owned trailer in the carrier’s possession under a written interchange agreement. Standard trailer interchange coverage includes:
- Collision: Physical damage to the trailer from a collision with another vehicle, object, or road surface
- Comprehensive: Non-collision physical damage including fire, theft, vandalism, weather events, and falling objects
- Upset and overturn: Damage from the trailer tipping or overturning during transit
- Loading and unloading damage: Physical damage incurred while the trailer is being loaded or unloaded under the interchange agreement
Coverage applies from the moment the carrier takes legal possession under the interchange agreement until the trailer is returned and accepted back by the other party.
Trailer Interchange Insurance vs. Non-Owned Trailer Coverage
These two coverages are frequently confused, but they serve different purposes and respond to different circumstances. The distinction matters because purchasing the wrong product leaves the carrier exposed.
| Feature | Trailer Interchange Insurance | Non-Owned Trailer Coverage |
|---|---|---|
| Written agreement required? | Yes — formal written interchange agreement | No — covers casual or informal use |
| Applies when? | Under a formal interchange arrangement | When using a trailer without a written agreement |
| Common use? | Port drayage, intermodal, LTL interchange | Owner-operators picking up a shipper’s drop trailer |
| Structure? | Standalone or physical damage endorsement | Usually a policy endorsement |
The practical rule: if there is a written interchange agreement transferring legal custody of the trailer, trailer interchange insurance is the correct product. If a driver is using a trailer informally — no written contract, no formal agreement — non-owned trailer coverage is the appropriate product.
Carriers who operate in both environments need both coverages properly structured on the same program. A carrier doing port drayage and also occasionally picking up shipper drop trailers should confirm explicitly with their broker that each exposure is addressed by the correct coverage.
Who Needs Trailer Interchange Insurance?
Port Drayage Carriers
Port drayage is the highest-volume trailer interchange environment in the country. Every container pulled out of a marine terminal under a chassis pool arrangement moves under a written interchange agreement — typically the chassis pool interchange receipt issued by the terminal operator or chassis lessor. Drayage carriers who operate without trailer interchange insurance are uninsured for the most common damage exposure in their daily operation.
LST Insurance works with drayage carriers across eight of the country’s most active port markets:
- Port of Savannah, Georgia (Garden City Terminal — the busiest single-terminal container port in the United States at 5.5M+ TEU/yr; served by Inland Port Gainesville and Inland Port Bainbridge for inland repositioning): Chassis pool drayage generates continuous interchange exposure on I-16, I-95, the Savannah-to-Atlanta inland freight corridor, and the I-75 Dalton NW Georgia corridor.
- Port of Charleston, South Carolina (Wando Welch Terminal and Hugh K. Leatherman Terminal — approximately 2.7M TEU/yr combined): The I-26/I-526 North Charleston interchange zone is one of the densest drayage concentration points in the Southeast.
- PortMiami and Port Everglades, Florida (PortMiami at 1.2M+ TEU/yr; Port Everglades at approximately 1.1M TEU/yr plus petroleum): South Florida drayage operates in one of the highest-litigation corridors in the country — Miami-Dade, Broward, and Palm Beach counties. Carriers should ensure trailer interchange limits reflect that nuclear verdict exposure.
- Port of Mobile, Alabama (Choctaw Point Terminal, Theodore Industrial Complex — Alabama State Port Authority): Port of Mobile drayage on the I-10/US-98 coastal corridor carries trailer interchange exposure through the Mobile Bay zone into the I-65 Birmingham corridor.
- Port of Wilmington, North Carolina (NC State Ports Authority container terminal, New Hanover County, Cape Fear River): Wilmington port drayage operates on I-40 and US-74 with seasonal hurricane exposure June through November. Carriers should confirm comprehensive coverage extends through storm events during active interchange periods.
- Port of Toledo, Ohio (Lucas County — Great Lakes cargo hub): Port of Toledo drayage involves chassis interchange for Great Lakes container movements, with repositioning exposure on I-75, I-80/I-90 Ohio Turnpike, and the I-280 Toledo metro corridor.
Intermodal Carriers
Carriers connecting with Class I railroads at intermodal terminals routinely take possession of chassis under written interchange arrangements. The Memphis, Tennessee intermodal hub — centered on the FedEx World Hub at Memphis International Airport (Shelby County, the largest cargo airport complex in the world by daily volume) and the CSX and Union Pacific intermodal terminals serving the greater Memphis distribution cluster — is one of the highest-volume intermodal interchange environments in LST’s service territory. Carriers operating at Memphis intermodal terminals need trailer interchange coverage with limits appropriate for the chassis values in circulation.
Fleet Operators with Hub-and-Spoke Networks
Fleet operators running scheduled routes between distribution centers often use trailer pools where trailers are continuously in circulation among multiple entities. Any written agreement that transfers legal custody of a trailer between parties — even affiliated entities operating under separate FMCSA authorities — can constitute a trailer interchange arrangement requiring trailer interchange coverage on the fleet program.
Owner-Operators Dispatched to Port Drayage
An owner-operator leased to a motor carrier who is dispatched to a marine terminal to pull a chassis from a pool may be operating under an interchange agreement. The owner-operator’s individual trucking policy will typically not extend to physical damage on a trailer they do not own. If the motor carrier’s program does not include trailer interchange coverage or does not extend it to leased owner-operators, the exposure falls into a gap that no policy covers — and the driver may face a personal liability claim for the damaged chassis.
FMCSA Filing Requirements for Trailer Interchange
The FMCSA does not require trailer interchange insurance as a standalone federal filing in the same way primary auto liability requires an MCS-90 endorsement. However, interchange agreements are governed by 49 CFR Part 376 and must be in writing, signed by both parties, and contain specified financial responsibility provisions. Any motor carrier operating under an FMCSA operating authority (MC number/USDOT number) who enters into a trailer interchange agreement is contractually obligated to carry the coverage the agreement requires.
The major chassis pool operators and leasing companies — DCLI, TRAC Intermodal, Flexi-Van, and Interpool — include trailer interchange insurance requirements in their standard chassis pool interchange receipts. These are contractual requirements enforced through terminal access: carriers without proof of appropriate trailer interchange coverage can be denied entry to the terminal. The practical result is the same as a regulatory mandate — without trailer interchange insurance, a port drayage carrier cannot operate.
What Trailer Interchange Insurance Does NOT Cover
Understanding the coverage boundaries is as important as understanding what the policy covers:
- Cargo inside the trailer — Trailer interchange covers the trailer itself. Cargo requires separate motor truck cargo insurance.
- Third-party bodily injury or property damage — Trailer interchange is physical damage coverage. Third-party liability requires primary auto liability insurance.
- The carrier’s own trailers — A carrier’s owned trailers require physical damage coverage on the carrier’s own physical damage policy, not trailer interchange.
- Trailers used without a written agreement — If there is no written interchange agreement in force, trailer interchange insurance will not respond. Non-owned trailer coverage is the appropriate product for informal use.
- Trailers outside the active interchange period — If the carrier no longer has legal possession under the agreement, coverage may not extend to damage occurring after the interchange period ends.
Trailer Interchange Insurance Rates in 2026
Trailer interchange insurance premiums are driven by several factors: the per-unit replacement value of the trailers being interchanged, the operating territory, the carrier’s loss history, CSA BASICs scores (particularly Unsafe Driving), the volume of interchange activity, and the coverage limit requested.
Typical 2026 rate ranges for standalone trailer interchange coverage:
| Operation Type | Annual Premium Range (2026) |
|---|---|
| Light interchange — occasional, standard dry van trailers | $350–$650/yr |
| Port drayage — standard coastal territory | $600–$1,100/yr |
| Port drayage — high-litigation territory (South FL, Atlanta metro) | $900–$1,500/yr |
| Intermodal — multi-lane, high-volume chassis operations | $800–$1,400/yr |
| Fleet with large chassis pool commitment (scheduled basis) | $1,200–$2,500+/yr |
CSA violations in the Unsafe Driving or Crash Indicator BASICs categories add 20–40% to base rates. Carriers with prior interchange claims will face additional surcharge. New authority carriers — those under two years’ operating history — may encounter limited market availability for standalone trailer interchange coverage, a condition LST Insurance recommends addressing before signing the first interchange agreement.
How to Structure Trailer Interchange Coverage Correctly
In LST Insurance’s experience working with port drayage carriers and intermodal operators across Georgia and the Southeast, the most common coverage structure error is purchasing trailer interchange insurance at the minimum limit required by the chassis pool operator — without verifying whether that limit reflects actual replacement cost for the chassis types being interchanged.
Standard 53-foot dry van trailers carry a replacement cost of $30,000–$45,000 in 2026. High-cube 53-foot refrigerated trailers run $75,000–$130,000. Marine chassis used in container operations typically value between $18,000 and $35,000 per unit. A carrier interchanging refrigerated trailers under a policy with a $50,000 per-unit limit is underinsured by 60% or more on a total loss. The gap between the policy limit and the actual replacement cost is an out-of-pocket liability for the carrier — not the insurer.
LST Insurance advises carriers to review their trailer interchange coverage limits at every policy renewal and confirm that per-unit stated values reflect current replacement cost — not the market values that applied when the policy was originally written two or three years prior. Trailer values have risen substantially since 2022 and have not fully corrected. An outdated stated value is a hidden deductible that does not appear on the declarations page.

Q&A: Direct Answers on Trailer Interchange Insurance
What is trailer interchange insurance?
Trailer interchange insurance provides physical damage coverage — collision, comprehensive, upset, and overturn — for a commercial trailer that a carrier does not own but has taken legal possession of under a written trailer interchange agreement. It covers damage to the trailer itself while it is in the carrier’s custody. It does not cover cargo inside the trailer, third-party liability, or the carrier’s own equipment — those require separate policies in a complete trucking insurance program.
Who is required to carry trailer interchange insurance?
Trailer interchange insurance is required by most port chassis pool operators, chassis leasing companies such as DCLI, TRAC Intermodal, Flexi-Van, and Interpool, and by the terms of written interchange agreements between motor carriers. While it is not mandated by a standalone FMCSA federal filing, any carrier entering into a written interchange agreement is contractually required to carry it — and port terminal access is typically denied without proof of coverage.
How much does trailer interchange insurance cost in 2026?
Trailer interchange insurance typically costs between $350 and $1,500 per year for most trucking operations in 2026, depending on the type of operation, territory, per-trailer replacement value, and the carrier’s CSA BASICs scores. Port drayage carriers in high-litigation territories — South Florida, Atlanta metro, Columbus metro — will pay more than carriers in lower-density corridors. Carriers with clean safety records and professional compliance programs consistently secure rates at or below the range midpoint.
Frequently Asked Questions: Trailer Interchange Insurance
What is the difference between trailer interchange insurance and non-owned trailer coverage?
Trailer interchange insurance applies when a carrier takes possession of a trailer under a formal written interchange agreement — as is standard in port drayage and intermodal operations. Non-owned trailer coverage applies when a driver occasionally uses a trailer they do not own without a formal written agreement, such as picking up a shipper’s drop trailer at a customer location. Carriers who operate in both environments should confirm with their broker that each exposure is addressed by the correct coverage on the same program.
Does the MCS-90 endorsement cover trailer damage under an interchange agreement?
No. The MCS-90 endorsement is a federal filing that guarantees minimum financial responsibility for bodily injury and property damage to third parties under 49 CFR Part 387. It does not provide physical damage coverage for the trailer itself and does not respond to claims under a trailer interchange agreement. The MCS-90 endorsement and trailer interchange insurance serve entirely different purposes and must both be in place for a complete commercial trucking coverage program.
Is trailer interchange insurance required for all carriers?
No. Only carriers who operate trailers under written interchange agreements require trailer interchange insurance. Carriers who haul exclusively on their own trailers — or on trailers leased directly to them under a motor carrier equipment lease governed by 49 CFR Part 376 — do not need trailer interchange coverage. The trigger is the written interchange agreement that transfers legal custody and risk of loss from one party to another. If there is no such agreement, there is no trailer interchange requirement.
Can owner-operators get trailer interchange insurance?
Yes. Owner-operators dispatched to move trailers under interchange agreements — such as drayage drivers pulling port chassis — can obtain trailer interchange insurance as a standalone policy or as an endorsement to their existing trucking program. Owner-operators should first confirm whether the motor carrier’s master program extends trailer interchange coverage to leased drivers operating under that carrier’s authority. If it does not, the owner-operator should carry their own coverage to close the gap.
What coverage limit should a carrier carry for trailer interchange insurance?
The minimum acceptable limit is whatever the interchange agreement or chassis pool contract requires. The correct limit, however, is the full replacement cost of the most valuable trailer type the carrier expects to handle under the agreement. Standard 53-foot dry van trailers run $30,000–$45,000 in 2026. Refrigerated trailers run $75,000–$130,000. Marine chassis run $18,000–$35,000. Carriers who set their limits at the contractual minimum without accounting for the actual replacement cost of the equipment they haul are creating a gap that becomes a direct out-of-pocket expense at the time of a total loss.
