12.2 Commercial Auto Liability and Physical Damage

Key Takeaways

  • Covered Autos Liability pays sums the insured is legally obligated to pay for bodily injury or property damage from an accident arising out of ownership, maintenance, or USE of a covered auto, including loading and unloading.
  • Supplementary payments - defense, bail bonds up to $2,000, and loss of earnings up to $250/day - are paid IN ADDITION to the liability limit.
  • Major liability exclusions: expected/intended injury, workers' compensation, fellow-employee, care-custody-control (cargo), pollution, and most contractual liability (except insured contracts).
  • Physical damage is FIRST-PARTY coverage on the insured's own autos: comprehensive (other than collision), collision (impact/overturn), and specified causes of loss (named peril, cheapest).
  • Valuation is the LESSER of Actual Cash Value (ACV) or cost to repair/replace, minus the deductible; the deductible applies per covered auto, per occurrence.

The Liability Insuring Agreement

Under Covered Autos Liability (Section II), the insurer pays all sums an insured legally must pay as damages for bodily injury (BI) or property damage (PD) caused by an accident and resulting from the ownership, maintenance, or use of a covered auto. The insurer also has the right and duty to defend; defense ends only when the limit is exhausted by judgments or settlements.

TriggerExample
OwnershipA defect in the insured's owned truck causes a crash
MaintenanceNeglected brakes fail and the truck rear-ends a car
UseThe driver runs a light and injures a pedestrian
Loading/UnloadingA driver drops freight on a customer's foot

Loading and unloading is treated as part of 'use,' so cargo-handling injuries near the vehicle are covered. The line is drawn at completion: once goods reach their final resting place, a later injury is no longer loading or unloading.

Limits: Combined Single Limit

The commercial-auto liability limit is almost always a Combined Single Limit (CSL) - one dollar amount (for example, $1,000,000) covering BI AND PD in any combination from a single accident. This contrasts with split limits (such as 100/300/50) seen on many personal auto policies. The CSL is the most the insurer pays for the total of all damages from one accident, regardless of how many insureds, claims, or vehicles are involved.

Worked split-limit comparison

An accident produces $90,000 BI to one person, $260,000 BI total to three people, and $60,000 PD. Compare two policies:

  • Split limits 100/300/50: pays up to $100,000 per person ($90,000 paid), $300,000 per accident BI ($260,000 paid), but only $50,000 of the $60,000 PD - the insured owes $10,000.
  • CSL $300,000: the $320,000 total exceeds the limit, so the insurer pays $300,000 and the insured owes $20,000, but PD is not separately capped.

The CSL avoids the per-line gap that bit the split-limit insured on PD.

Supplementary Payments - Above the Limit

Paid in addition to the liability limit, so they never erode money available to claimants:

PaymentAmount
Defense costs and allocated expensesNo dollar cap (until limit exhausted)
Bail bondsUp to $2,000
Appeal / release-of-attachment bondsActual cost (no duty to apply)
Post-judgment interestUntil insurer pays/tenders the limit
Insured's loss of earnings to assist defenseUp to $250 per day
Other reasonable expenses at insurer's requestActual cost

Out of State Extension

When a covered auto enters a state requiring higher limits or a coverage the policy lacks (such as no-fault), the Out of State provision automatically raises limits and adds the required minimum coverage - the insured never buys a second policy.

Key Liability Exclusions

ExclusionWhat It RemovesNotable Exception
Expected/Intended InjuryHarm the insured expected or intendedReasonable force to protect persons/property
Contractual LiabilityLiability assumed in a contractAn 'insured contract' (e.g., lease of the auto)
Workers' CompensationWC/disability obligationsNone - buy WC separately
Employer's LiabilityInjury to an employee in the course of employmentDomestic employee not entitled to WC
Fellow EmployeeBI to a co-worker by an insuredRemovable by endorsement
Care, Custody, or ControlCargo / property in the insured's careLiability for a covered auto you lease
PollutionMost pollutant releasesLimited fuel-system / in-transit situations

High-yield trap: Damaged cargo inside the insured's truck is NOT covered by liability (care, custody, or control) - it needs motor truck cargo or inland marine coverage. Employee injuries route to workers' compensation, not the auto policy.

Physical Damage - First-Party Coverage

Physical Damage (Section III) pays for direct and accidental loss to the insured's own covered auto, regardless of fault, subject to a deductible. There are three options:

  • Comprehensive (Other Than Collision): broadest - pays any direct loss EXCEPT collision; covers theft, fire, hail, flood, vandalism, glass, falling objects, and contact with a bird or animal.
  • Collision: overturn of the auto or impact with another vehicle or object.
  • Specified Causes of Loss: named-peril, cheapest - fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, mischief/vandalism, and the sinking/burning/collision/derailment of a conveyance transporting the auto. Does NOT cover the auto's own collision, glass-only breakage, or falling objects.

Hail/FloodYesNoYes

Vehicle overturn/impactNoYesNo

Classic trap: A deer running into the car is comprehensive; swerving and hitting a tree to avoid the deer is collision.

Coinsurance and Stated-Amount Underinsurance

Unlike commercial property, BAP physical damage has no coinsurance clause for ACV settlement - it simply pays the lesser of ACV or repair cost. But a Stated Amount endorsement creates an underinsurance risk that mimics coinsurance. If an insured states a value too low to save premium, the payout is capped at that stated amount even when ACV is higher.

Worked stated-amount example: A specialty rig has an ACV of $60,000 but is written for a stated amount of $45,000 with a $2,500 deductible. After a total loss the insurer pays the lesser of stated amount, ACV, or repair cost: $45,000 - $2,500 = $42,500. The insured absorbed the $15,000 shortfall by understating value - a frequent exam point distinguishing stated-amount from agreed-value (which pays the full agreed figure).

Valuation, Deductibles, and a Worked Loss

The insurer pays the lesser of the auto's Actual Cash Value (ACV) or the cost to repair/replace with like kind and quality, minus the deductible. A Stated Amount endorsement caps payout at the lesser of stated amount, ACV, or repair cost. Diminution in value (lost resale value after a quality repair) is expressly excluded.

Worked ACV example

A box truck with a replacement cost of $40,000 has depreciated 45 percent; deductible is $1,000.

  • ACV = $40,000 x (1 - 0.45) = $22,000
  • Less deductible: $22,000 - $1,000 = $21,000 paid

Worked multi-vehicle deductible example

A hailstorm damages three scheduled vans, each with a $500 comprehensive deductible; estimates are $4,000, $6,000, and $9,500.

  • $3,500 + $5,500 + $9,000 = $18,000 paid (a separate deductible per auto).

The deductible applies per covered auto, per occurrence - students wrongly apply a single deductible to the whole storm. Standard transportation-expense reimbursement is $20/day up to $600, payable only after theft of a covered private passenger auto, beginning 48 hours after the theft.
