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 caused by an accident and resulting from auto ownership, maintenance, or use.
- Limits are usually a single Combined Single Limit (CSL); split limits (e.g., 100/300/50) are also possible.
- Physical Damage offers comprehensive (other than collision), collision, and specified causes of loss, paid at actual cash value (ACV) or cost to repair, less the deductible.
- Loading and unloading is covered; the BACF has its own pollution liability exclusion with narrow carve-backs.
- Coverage is excess over any other collectible insurance for hired or borrowed autos.
Covered Autos Liability
Covered Autos Liability is Section II of the Business Auto Coverage Form. It pays all sums an insured becomes legally obligated to pay as damages because of bodily injury (BI) or property damage (PD) caused by an accident and resulting from the ownership, maintenance, or use of a covered auto.
Liability includes a separate supplementary payments provision and a duty to defend that exists even when claims are groundless; defense costs are paid in addition to the limit. The insurer's duty to defend ends once the applicable limit of insurance is exhausted by payment of judgments or settlements.
The coverage also includes out-of-state extensions that automatically raise limits to meet the financial responsibility requirements of the state where the accident occurs - an exam favorite.
Limits: Combined Single vs. Split
Commercial auto liability is most often written on a Combined Single Limit (CSL) - one limit for any combination of BI and PD per accident.
Split limits state three numbers, written as per-person BI / per-accident BI / per-accident PD, such as 100/300/50 (meaning $100,000 per person, $300,000 per accident for BI, and $50,000 for PD).
Worked split-limit example
A covered truck injures three people - $80,000, $120,000, and $40,000 - and causes $60,000 in property damage. Under 100/300/50:
| Claim | Limit Applied | Paid |
|---|---|---|
| Person 1 ($80,000) | $100,000 per person cap | $80,000 |
| Person 2 ($120,000) | $100,000 per person cap | $100,000 |
| Person 3 ($40,000) | $100,000 per person cap | $40,000 |
| BI subtotal | $300,000 per accident cap | $220,000 |
| Property damage ($60,000) | $50,000 PD cap | $50,000 |
Person 2 is cut to $100,000 by the per-person cap; PD is capped at $50,000. A $300,000 CSL would have paid the full $220,000 BI but only $80,000 of the $280,000 total - showing how the two structures differ.
Under a 250/500/100 split limit, a single accident injures two people ($300,000 and $150,000) and causes $120,000 property damage. How much does the policy pay in total?
Physical Damage Coverage
Section III - Physical Damage restores the insured's own autos. It is shown by symbol on the declarations and is written in three parts:
| Coverage | What It Pays For |
|---|---|
| Comprehensive | All direct loss EXCEPT collision and overturn (theft, fire, hail, glass, animal strike, vandalism) |
| Collision | Impact with another object or overturn |
| Specified Causes of Loss | Named perils only: fire, lightning, explosion, theft, windstorm, hail, flood, mischief - cheaper than comprehensive |
The insurer pays the lesser of the actual cash value (ACV) of the damaged property or the cost to repair or replace, minus the deductible. Comprehensive and collision each carry their own deductible; specified causes of loss generally applies without one except for theft.
ACV Example and Other Insurance
A box truck with an ACV of $28,000 is totaled in a collision. The collision deductible is $1,000. Repair would cost $35,000, so the truck is a total loss. The insurer pays the lesser of ACV or repair cost ($28,000) minus the $1,000 deductible = $27,000.
Other-insurance rules to memorize:
- For owned autos, the BACF is primary.
- For hired or borrowed autos, the BACF is excess over any other collectible insurance.
- Loading and unloading is part of the use of an auto and is covered.
- The pollution exclusion removes most pollutant cleanup, with narrow carve-backs (for example, fuel, lubricants, or fluids needed to operate the auto that escape from a covered loss).
Key Liability Exclusions
Commercial auto liability is broad, but several exclusions are heavily tested. Knowing what the form refuses to pay is as important as knowing what it covers.
| Exclusion | Effect |
|---|---|
| Expected or intended injury | No coverage for harm the insured deliberately causes |
| Workers compensation / employer's liability | Auto liability is not a substitute for workers comp |
| Fellow employee | One employee injuring another in the course of employment |
| Care, custody, or control | Property of others in the insured's care (handled by garagekeepers/cargo) |
| Pollution | Most pollutant discharge, with narrow operating-fluid carve-backs |
| Racing | Organized racing or speed contests |
Exam trap: the fellow-employee exclusion is why a passenger-employee injured by a co-worker driver must usually look to workers compensation, not the auto liability coverage. Some risks buy back this exclusion by endorsement.
Medical Payments, UM/UIM, and Stacking
Beyond liability and physical damage, the policy can activate first-party coverages by entering a limit on the declarations.
- Auto Medical Payments pays reasonable and necessary medical and funeral expenses for an insured and occupants of a covered auto, regardless of fault, usually within a stated time after the accident.
- Uninsured/Underinsured Motorist (UM/UIM) pays the insured's bodily injury (and in some states property damage) when an at-fault driver is uninsured or carries inadequate limits. UIM responds when the other driver's limit is lower than the insured's damages.
- No-Fault / Personal Injury Protection (PIP) is mandatory in certain states and is activated by Symbol 5.
Worked UM example: an insured suffers $120,000 in injuries; the at-fault driver carries only $50,000 in liability. With $300,000 UIM, the insured collects $50,000 from the other driver and up to $70,000 more from UIM, reaching the $120,000 of damages without exceeding the UIM limit.
