13.3 Garagekeepers & Motor Carrier Coverages (MCS-90)

Key Takeaways

  • The Auto Dealers Coverage Form (CA 00 25) / Garagekeepers Coverage protects customer vehicles left in the insured's care, custody, or control for servicing, repair, parking, or storage, bypassing the standard CGL care/custody/control exclusion.
  • Garagekeepers offers three distinct coverage options: Legal Liability (fault-based negligence), Direct Excess (pays without regard to liability excess over the customer's personal policy), and Direct Primary (pays first-dollar goodwill coverage without regard to fault or customer insurance).
  • The Motor Carrier Coverage Form (CA 00 20) insures commercial enterprises transporting property or passengers for hire, featuring specialized Trailer Interchange coverage for non-owned trailers under interchange agreements.
  • The MCS-90 Endorsement is a federally mandated public liability endorsement under the Motor Carrier Act of 1980, requiring financial responsibility limits of $750,000 (general freight), $1,000,000 (oil/hazardous waste), or $5,000,000 (hazardous substances/explosives).
  • The MCS-90 operates as a statutory suretyship endorsement ensuring compensation to injured third parties regardless of policy exclusions or conditions, granting the insurer an absolute right of reimbursement against the motor carrier.

13.3 Garagekeepers & Motor Carrier Coverages (MCS-90)

Standard commercial auto and general liability policies contain strict exclusions for personal property in the insured's care, custody, or control (CCC). For businesses that service, repair, park, store, or transport customer vehicles or freight—such as auto repair shops, car dealerships, valet parking operators, and interstate motor carriers—specialized policy forms and endorsements are required to close critical coverage gaps and satisfy federal regulatory mandates.


1. Auto Dealers Coverage Form & Garagekeepers Insurance

Businesses such as automotive dealerships, repair facilities, body shops, transmission service centers, and commercial parking garages take temporary possession of customer vehicles. If a customer's vehicle is damaged, vandalized, or destroyed while in the shop's possession, neither the Commercial General Liability (CGL) policy (which excludes CCC property) nor the standard Business Auto Coverage Form provides first-party physical damage protection.

To resolve this exposure, the insurance industry utilizes the Auto Dealers Coverage Form (CA 00 25) (formerly the Garage Coverage Form) and specialized Garagekeepers Coverage (CA 99 37).

The Three Garagekeepers Coverage Options

One of the most heavily tested areas on the North Carolina adjuster exam is the precise difference between the three Garagekeepers coverage options:

└───────────────────┴─────────────────────────────────────────────────────┘

In-Depth Breakdown of Settlement Options

  1. Legal Liability Basis (Default / Standard):

    • The insurer will pay for direct loss to a customer's auto only if the named insured is legally liable for the damage based on common law negligence.
    • Claims Example: If a burglar breaks into a locked repair shop at night or a severe hailstorm dents 20 customer cars parked outside, the shop owner was not negligent. Under Legal Liability, the insurer denies the claim, forcing customers to file under their own Personal Auto Policies.
  2. Direct Excess Basis:

    • The insurer agrees to pay for direct physical loss to a customer's vehicle without regard to legal liability, but coverage applies strictly in excess of any other collectible physical damage insurance available to the vehicle owner.
    • Claims Example: A hailstorm causes $5,000 in damage to a customer's car parked at a repair shop. The customer carries personal comprehensive coverage with a $500 deductible. The customer's personal insurer pays $4,500. Under Direct Excess, the garage policy pays the customer's $500 deductible. If the customer carried no comprehensive coverage, Direct Excess would pay the entire $5,000.
  3. Direct Primary Basis:

    • The insurer agrees to pay for direct physical loss to a customer's vehicle without regard to legal liability, acting as primary insurance regardless of whether the customer has their own personal auto insurance.
    • Claims Example: A tornado strikes a high-end luxury auto dealership service yard, destroying 15 customer vehicles. Under Direct Primary, the dealership's garagekeepers insurer immediately pays the full actual cash value for all 15 customer vehicles without requiring customers to report claims to their personal insurers, protecting the dealership's customer relationships and commercial reputation.

2. Motor Carrier Coverage Form (CA 00 20) & Trailer Interchange

Commercial transportation companies transporting commodities or passengers for hire face unique operational risks. The ISO Motor Carrier Coverage Form (CA 00 20) replaced the older Truckers Form (CA 00 12) to provide comprehensive coverage for both for-hire carriers (common and contract carriers) and private carriers.

Trailer Interchange Coverage

In the commercial freight and trucking industry, motor carriers frequently exchange trailers with other trucking companies to facilitate long-distance freight movement across regional territories. Under a written Trailer Interchange Agreement, Motor Carrier A pulls a trailer owned by Motor Carrier B.

Because the non-owned trailer is in the motor carrier's "care, custody, or control," standard BACF physical damage provisions exclude it. Trailer Interchange Coverage (Section III of CA 00 20) provides physical damage insurance (Comprehensive, Specified Causes of Loss, Collision) for non-owned trailers and equipment while in the insured's possession under a written interchange contract.

│  REQUIREMENTS FOR COVERAGE TO ATTACH:                                   │

│  2. Trailer is in the insured's CARE, CUSTODY, OR CONTROL.              │
│  3. There is a WRITTEN TRAILER INTERCHANGE AGREEMENT requiring the      │
│     motor carrier to maintain physical damage insurance on the trailer. │

└─────────────────────────────────────────────────────────────────────────┘

3. The Motor Carrier Act of 1980 & FMCSA Financial Responsibility Mandates

Under Title 49 of the Code of Federal Regulations (49 CFR Part 387), the Federal Motor Carrier Safety Administration (FMCSA) enforces strict financial responsibility requirements established by the Motor Carrier Act of 1980. Commercial motor carriers operating in interstate commerce or hauling hazardous materials must demonstrate continuous financial responsibility to ensure public protection.

4. The MCS-90 Endorsement: Suretyship Legal Mechanics & Claims Handling

To satisfy federal financial responsibility filings (Forms BMC-91 or BMC-91X with the FMCSA), commercial motor carriers must attach the MCS-90 Endorsement (Endorsement for Motor Carrier Policies of Insurance for Public Liability Under Sections 29 and 30 of the Motor Carrier Act of 1980) to their liability policy.

The Legal Nature of the MCS-90: Suretyship, Not Insurance

The MCS-90 is one of the most critical and frequently misunderstood documents in commercial transportation law. The MCS-90 is NOT an insurance policy; it is a statutory suretyship endorsement.

└─────────────────────────────────────────────────────────────────────────┘

Critical Adjuster Rules Regarding MCS-90

  1. Public Protection Only: The MCS-90 exists strictly for the benefit of the injured public. It covers third-party bodily injury, property damage, and statutory environmental restoration costs. It never pays first-party physical damage, cargo losses, or employee workers' compensation injuries.
  2. Nullification of Policy Defenses: If the motor carrier operates an unscheduled vehicle, hires an unlisted driver, operates outside the policy territory, or commits intentional fraud that would otherwise void coverage under the underlying policy, the insurer cannot assert these policy defenses against an injured third-party claimant. The insurer must pay the judgment up to the statutory MCS-90 limit ($750k, $1M, or $5M).
  3. Insurer's Right of Full Reimbursement: Once the insurer pays the injured third party under the mandate of the MCS-90, the insurer immediately exercises its statutory right of reimbursement against its own policyholder (the motor carrier) to recover 100% of the funds paid out.

5. Practical Adjuster Claim Scenarios

Scenario A: Dealership Hailstorm Damage Under Garagekeepers Options

Case File: A catastrophic hailstorm strikes Charlotte, causing $80,000 in physical damage to 20 customer vehicles parked in the service lot of Queen City Motors. Queen City was not negligent in any way.

Adjuster Analysis Under the 3 Garagekeepers Options:

  1. Under Legal Liability: The claim is DENIED. Queen City was not negligent; the loss was caused by an act of God. Customers must file under their own PAP comprehensive coverage.
  2. Under Direct Excess: If a customer carries a personal PAP with a $500 deductible, the customer's PAP pays the vehicle damage minus $500, and Queen City's garagekeepers policy pays the $500 deductible. For any customer without comprehensive insurance, Direct Excess pays the full repair cost.
  3. Under Direct Primary: Queen City's garagekeepers policy pays all $80,000 in repair costs immediately, providing first-dollar settlement without requiring customers to involve their personal auto carriers.

Scenario B: Unscheduled Tractor Highway Accident & MCS-90 Payout

Case File: High Country Freight operates an interstate trucking line with an MCS-90 endorsement providing $750,000 in financial responsibility. To handle holiday volume, High Country leases an unlisted tractor without notifying its insurer (violating policy terms). While hauling non-hazardous general freight on Interstate 85 in North Carolina, the tractor causes a collision resulting in an $800,000 wrongful death judgment in favor of an injured motorist's estate.

Adjuster Analysis: Under standard policy terms, the unscheduled tractor would be excluded. However, because the policy contains an MCS-90 endorsement, the insurer cannot assert the vehicle scheduling defense against the injured public.

Payout Mechanics: The insurer must pay the statutory limit of $750,000 to the deceased victim's estate. The insurer then immediately initiates legal action against High Country Freight under its statutory right of reimbursement to recover the entire $750,000.
