Port drayage insurance for operators serving the Ports of Los Angeles and Long Beach costs $14,000 to $22,000 per year in 2026 for a single-tractor operation. Port drayage requires specialized coverage beyond standard trucking insurance, including trailer interchange coverage (UIIA-compliant), proper chassis coverage, pollution liability for tanker operations, and expanded general liability for terminal access. The Port of Los Angeles and Port of Long Beach together handle 40% of US container imports, making this one of California's most active but most regulated trucking environments.
What's in this guide
What makes port drayage insurance different?
Port drayage — moving containers between marine terminals, rail yards, and customer facilities — has unique insurance requirements that standard OTR trucking doesn't:
Trailer interchange is mandatory
Port drayage operators pull interchange trailers (containers on chassis) owned by steamship lines, not their own equipment. If you damage an interchange chassis or container, you're liable for repair or replacement. Standard trucking insurance doesn't cover non-owned equipment. You need specific trailer interchange coverage, ideally UIIA-compliant.
UIIA compliance is required for terminal access
The Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) is the industry contract required for access to most marine terminals and rail yards. UIIA compliance means carrying specific insurance coverages in specific amounts. Without UIIA compliance, you cannot pick up or deliver to most terminals in LA/LB.
Pollution liability can be required
If you handle fuel or chemical containers, pollution liability coverage (ISO MCS-90 endorsement or stand-alone pollution policy) may be required. Some terminals require pollution coverage regardless of cargo.
Chassis pool dynamics
LA/LB uses chassis pools (shared chassis provided by pool operators). Damage to pooled chassis has specific claim procedures different from owned equipment.
How much does port drayage insurance cost?
Port drayage insurance at the Ports of LA and Long Beach typically costs $14,000 to $22,000 per year in 2026 for a single-tractor operator with clean records. Fleet operators pay $11,000 to $17,000 per truck annually.
Port drayage rates run higher than OTR because:
- Trailer interchange exposure (damage to non-owned chassis/containers)
- Dense traffic environment (terminal congestion = more fender benders)
- High cargo values (import containers routinely exceed $500,000 in contents)
- Specialized underwriting (fewer carriers with appetite)
- Dispatcher/shipper expectations for $1M liability minimum
What is UIIA and what insurance does it require?
The UIIA (Uniform Intermodal Interchange and Facilities Access Agreement) is the standard contract between motor carriers and marine/rail terminals. UIIA is administered by the Intermodal Association of North America (IANA) and required for access to most LA/LB terminals.
UIIA minimum insurance requirements include:
- Commercial auto liability: $1,000,000 combined single limit
- Motor truck cargo: varies by terminal ($100,000 - $250,000 typical minimum)
- Trailer interchange: $100,000 minimum
- General liability: $1,000,000 per occurrence
- Workers' compensation: statutory limits
Some terminals require HIGHER limits than UIIA minimums — up to $2,000,000 auto liability and $500,000 cargo. Always verify with each terminal's specific access requirements.
UIIA Endorsement (Endorsement CA 99 50): Many UIIA-approved carriers add this specific endorsement, which automatically extends coverage to UIIA-compliant non-owned chassis/trailers. Ask your broker whether UIIA CA 99 50 is on your policy.

Trailer interchange coverage pays for damage to trailers (chassis, containers) you pull under a written interchange agreement. Without it, you're personally liable for damage to non-owned equipment.
Typical port drayage scenarios where trailer interchange pays:
- You pull a chassis from Port of LA with a hidden defect; the chassis fails on the 710 Freeway; you're charged for repair
- You back into another truck at the terminal, damaging the chassis rails
- You pull a container that's loaded incorrectly; the container shifts; you get charged for container damage
- Chassis gets damaged during an accident; pool operator bills you
Typical trailer interchange limits and costs
UIIA minimum is $100,000 in trailer interchange. Practical recommendation is $150,000-$250,000 to match typical chassis + container replacement values.
Cost: typically $400-$900 per year as an endorsement on commercial auto or cargo policy.
Common trailer interchange coverage gaps
- Exclusion for "regularly furnished" equipment — some policies exclude equipment that's interchanged as part of regular business. For port drayage where you pull chassis daily, this exclusion voids coverage. Demand removal.
- Named insured limitations — policy only covers trailer interchange for specific named motor carriers. If you work for multiple steamship lines, policy needs broader named insured clause.
- Deductible structure — some policies have $5,000+ deductibles on trailer interchange. For minor chassis damage, deductible exceeds claim value.
Which carriers write port drayage in California?
Port drayage is a specialty market with limited carrier options:
| Carrier | Port Drayage Fit | Notes |
|---|---|---|
| Great American Insurance | Excellent | Strong port drayage program, includes UIIA-compliant endorsement |
| Berkshire Hathaway GUARD | Excellent | LA/LB port drayage specialty, fleet-friendly |
| CNA Commercial | Good | Specialty transportation focus |
| Canopius (surplus) | Good | Hard-to-place drayage operators |
| Lloyd's of London syndicates | Specialty | Pollution liability, high-limit requirements |
| Hallmark / Trisura | Fair | Writes smaller drayage operators |
Standard commercial trucking carriers (Progressive, Cover Whale) may write basic coverage but often decline full UIIA-compliant port drayage due to trailer interchange complexity. Working with a broker who has specialty market access is essential.
Common port drayage insurance mistakes
Mistakes we see LA/LB port drayage operators make:
Trailer interchange exclusion on existing policy
Port drayage operators who bought general trucking insurance (not drayage-specific) often discover their policy has a "trailer interchange exclusion" — meaning every chassis they pull is uncovered. One damaged chassis becomes a $5,000-$15,000 out-of-pocket claim. This is the most common coverage gap we find.
Inadequate chassis / container limits
Standard $100K trailer interchange limit is UIIA minimum but may be inadequate for chassis pool damage claims. Chassis replacement runs $25,000-$45,000 in 2026. Container damage claims can exceed $50,000. Match limits to exposure.
Not verifying terminal-specific requirements
UIIA minimums apply broadly but individual terminals sometimes require higher limits. Getting turned away at the terminal because your policy doesn't meet their specific requirements wastes a day's revenue and damages broker relationships.
Ignoring pollution coverage for fuel/chemical work
If you haul fuel containers, chemical containers, or any hazmat through port drayage, pollution liability matters. Standard commercial auto policies exclude pollution events. A fuel spill cleanup at Port of LA can easily exceed $200,000.
Frequently asked questions
Is port drayage insurance more expensive than regular trucking insurance?
Yes. Port drayage insurance typically costs 20-40% more than equivalent OTR trucking insurance due to trailer interchange exposure, dense traffic environment, high cargo values, and specialized underwriting requirements. Typical port drayage owner-operator pays $14,000-$22,000 annually vs. $10,000-$16,000 for OTR.
What is UIIA compliance and do I need it?
UIIA (Uniform Intermodal Interchange and Facilities Access Agreement) is the standard contract required for access to most marine terminals and rail yards. If you haul containers at the Port of LA, Port of Long Beach, or any major US port, UIIA compliance is required. UIIA compliance means your insurance meets specific minimum coverage requirements listed in the agreement.
Do I need pollution coverage for port drayage?
Depends on cargo. If you haul ISO tank containers, fuel containers, chemical containers, or any hazmat through port drayage, pollution liability is strongly recommended and often required by terminals. Standard dry container work typically doesn't require pollution liability, but confirm with each terminal.
Does my insurance cover the chassis I pull?
Only if you have trailer interchange coverage (UIIA-compliant ideally). Standard commercial auto liability does NOT cover damage to non-owned trailers/chassis — it only covers damage you cause to OTHER people's vehicles. Trailer interchange is a separate coverage specifically for the equipment you pull but don't own.
Can I do port drayage with less than $1M liability?
No. Most marine terminals require $1,000,000 commercial auto liability minimum for access, per UIIA standards. Some terminals require $2,000,000. Running less than $1M effectively locks you out of the port drayage market. Shippers and brokers also universally require $1M minimum.
Who writes port drayage insurance in Los Angeles?
Specialty carriers with LA/LB port drayage appetite include Great American Insurance Group, Berkshire Hathaway GUARD, CNA Commercial, Canopius (surplus), and Lloyd's of London syndicates for higher-limit or specialty risks. Standard trucking carriers (Progressive, Cover Whale) often decline full UIIA-compliant drayage policies. Working with a broker with specialty market access is essential.
