12.2 Commercial Auto Liability and Physical Damage
Key Takeaways
- Covered Autos Liability pays BI and PD the insured is legally obligated to pay, plus a duty to defend whose costs are paid in addition to the limit.
- Commercial auto typically uses a Combined Single Limit (CSL) rather than the split limits common to personal auto.
- Comprehensive covers other-than-collision perils (theft, hail, glass, animal strike); collision covers impact and overturn; specified causes of loss is named-peril and cheaper.
- Physical damage settles at the lesser of ACV or repair/replace cost minus the deductible; ACV equals replacement cost minus depreciation.
- An employee using their own auto and a garage using a customer's auto are NOT insureds under the BACF.
Covered Autos Liability (Section II)
Covered Autos Liability pays sums an insured becomes legally obligated to pay as damages for bodily injury (BI) or property damage (PD) caused by an accident and arising out of ownership, maintenance, or use of a covered auto. The insurer also assumes the duty to defend — and defense costs are paid in addition to the limit of insurance, not inside it.
Most commercial auto liability is written with a single Combined Single Limit (CSL) — one dollar amount per accident covering BI and PD together. The Personal Auto Policy more often uses split limits, so the CSL is a key commercial distinction.
Who Is an Insured
The BACF insured definition is intentionally broad:
- The named insured for any covered auto.
- Anyone using a covered auto the named insured owns, hires, or borrows — with permission.
- Anyone liable for the conduct of an insured (vicarious liability), but only to the extent of that liability.
Trap: An employee is not an insured when using the employee's own auto, and a person in the business of servicing autos (a garage) is not an insured while using a customer's covered auto — those exposures need other forms.
Supplementary Payments
Paid in addition to the liability limit:
| Payment | Amount |
|---|---|
| Defense costs | Unlimited (in addition to limit) |
| Bail bonds | Up to $2,000 |
| Bonds to release attachments | Up to the limit |
| Loss of earnings to attend trial | Up to $250 per day |
| Post-judgment interest | Full |
Exclusions to Memorize
Liability does not cover: expected or intended injury; workers compensation/employer's liability obligations; pollution from a covered auto (with narrow exceptions); war; the care, custody, or control of property; handling of property before/after it is on the auto; and movement of property by mechanical device (other than a hand truck) not attached to the covered auto.
Physical Damage (Section III)
Physical damage insures the insured's own covered autos. Three coverages are offered:
| Coverage | What It Pays |
|---|---|
| Comprehensive | All direct loss EXCEPT collision/overturn (fire, theft, hail, glass, animal strike) |
| Specified Causes of Loss | Named perils only: fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, mischief, vandalism — cheaper than comprehensive |
| Collision | Collision with another object or overturn of the covered auto |
A glass-breakage and an animal collision are paid under comprehensive, not collision — a frequent exam point.
Valuation, Deductibles, and Limits
Physical damage is settled at the lesser of actual cash value (ACV) or cost to repair/replace, minus the deductible. ACV = replacement cost minus depreciation.
Worked example (ACV settlement): A delivery van is totaled. Replacement cost $42,000; depreciation 30%; comprehensive deductible $500. ACV = $42,000 - (0.30 x $42,000) = $42,000 - $12,600 = $29,400. Insurer pays $29,400 - $500 = $28,900.
Comprehensive and specified-causes losses caused by a covered theft carry a special rule: a separate $10/day, $300 maximum transportation-expenses benefit begins 48 hours after the theft and ends when the auto is returned or the insurer pays for the loss. A towing sublimit can be added for private passenger autos.
Trap: There is no deductible for fire or lightning loss under Specified Causes of Loss only if the form so states; under standard comprehensive the scheduled deductible always applies except for glass repair the insurer may waive.
Limits of Insurance and Other Insurance
For liability, the limit shown on the declarations is the most the insurer pays for all damages from any one accident, regardless of the number of insureds, claims, autos, or vehicles involved — a single CSL is not stacked per claimant. For physical damage, the most paid is the lesser of ACV or repair cost, never more than it would cost to repair or replace with like kind and quality.
The other insurance condition coordinates overlapping policies. For an owned covered auto the BACF is primary; for a hired or borrowed auto it is generally excess over any other collectible coverage. This ordering is why a business renting a truck may find its policy excess and the rental company's primary — a frequent claims-handling question.
Two or More Coverage Forms Condition
When two or more BACFs issued by the same insurer apply to the same loss, the insurer pays no more than the highest applicable limit under any one form — it does not add the limits together. Recognizing this anti-stacking rule prevents the common error of summing limits across a company's multiple auto policies.
A covered box truck strikes a deer at night, damaging the front end. Repairs cost $6,400. The policy carries a $1,000 comprehensive deductible and a $1,000 collision deductible. How is the loss settled?
Under Covered Autos Liability, the insurer's payment of defense costs and a $2,000 bail bond is best described as:
Commercial Auto Physical Damage and the Coverage Triggers
Commercial auto physical damage mirrors the personal auto structure but is keyed to covered-auto symbols. The two perils, and a third optional add-on, are tested directly.
| Coverage | Pays for | Symbol note |
|---|---|---|
| Comprehensive | All physical damage except collision (fire, theft, glass, animal, flood) | Symbol 7 (scheduled) typical |
| Specified Causes of Loss | Named perils only (fire, theft, windstorm) - cheaper than comprehensive | Alternative to comprehensive |
| Collision | Impact with another object or overturn | Subject to deductible |
Worked example: a covered truck (Symbol 7) worth $80,000 ACV is stolen. Comprehensive pays $80,000 ACV minus the deductible (commonly $1,000), settling at $79,000. If the business carried only collision, theft would not be covered.
Exam Trap: Specified Causes of Loss is narrower than Comprehensive - it pays only for listed perils, so a falling-object or accidental-glass loss not on the list is uncovered. Liability uses Symbol 1 (any auto) for the broadest protection, but physical damage cannot use Symbol 1 and must use scheduled or hired-auto symbols.
