12.2 Commercial Auto Liability and Physical Damage

Section II — Covered Autos Liability Coverage

The BAP liability insuring agreement promises to pay "all sums an insured legally must pay as damages because of bodily injury or property damage to which this insurance applies, caused by an accident and resulting from the ownership, maintenance or use of a covered auto."

Liability is typically written with a single Combined Single Limit (CSL) — one limit applying to BI and PD combined per accident — rather than split limits. The insurer also has the duty to defend and pays defense costs in addition to the limit of insurance. Supplementary payments include bail bonds up to $2,000 and up to $250 per day for lost earnings to attend hearings at the insurer's request.

Who Is an Insured

Under the BAP, the named insured is covered for any covered auto. Additionally, anyone using a covered auto with permission is an insured (permissive use), with key exceptions: the owner of a hired or borrowed auto, employees using their own autos, and someone in the auto-selling/servicing business (covered separately under garage rules).

Worked CSL example: an insured truck driver causes an accident with $180,000 bodily injury and $90,000 property damage, $270,000 total. With a $250,000 CSL the insurer does not pay $270,000 — the CSL caps total at $250,000. The insurer pays $250,000 and the insured owes the remaining $20,000. The single limit is the chief reason commercial buyers prefer a CSL over split limits.

Split Limits vs. CSL

When split limits are used (less common in commercial auto), they read like $100,000 / $300,000 / $50,000: $100,000 per person BI, $300,000 per accident BI, and $50,000 PD per accident. The per-person cap is applied first, then the per-accident cap, then the separate PD cap.

Worked split-limit example: three people are injured for $80,000, $120,000, and $60,000 (total $260,000) under 100/300/50 limits. The per-person cap of $100,000 reduces the $120,000 claim to $100,000, so BI = $80,000 + $100,000 + $60,000 = $240,000. The $300,000 per-accident cap is not breached, so the full $240,000 is paid for bodily injury, plus any property damage up to $50,000.

Section III — Physical Damage Coverage

Physical damage is written in three forms:

• Comprehensive — all direct loss except collision and overturn (fire, theft, vandalism, glass, animal strike, flood).
• Specified Causes of Loss — a narrower named-peril alternative (fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, mischief, vehicle sinking) at lower cost.
• Collision — impact with another object or overturn.

Each form is written subject to a deductible (commonly $500 or $1,000) applied per occurrence. Glass breakage, animal strikes, and falling-object damage may be claimed under comprehensive without the collision deductible. Comprehensive and specified causes of loss are mutually exclusive choices — you buy one or the other, never both, on the same auto.

Valuation and Deductible Math

Losses are settled at the lesser of actual cash value (ACV) or cost to repair/replace, minus the deductible. ACV = replacement cost minus depreciation.

Worked example: a 5-year-old box truck with a replacement cost of $60,000 has depreciated 50%, so ACV = $30,000. It is totaled and the policy carries a $1,000 collision deductible. The insurer pays $30,000 - $1,000 = $29,000. A towing-and-labor sublimit (often $75 per disablement) applies only to private passenger autos when shown; rental reimbursement and electronic-equipment coverage are added by endorsement.

The Three Physical-Damage Coverages and Their Boundaries

Business Auto physical damage comes in three flavors the exam keeps distinct. Collision pays for impact with another object or overturn. Comprehensive (other than collision) pays for nearly everything else, including fire, theft, vandalism, flood, falling objects, and animal strikes; hitting a deer is comprehensive, while swerving and striking a tree is collision.

Specified Causes of Loss is a narrower, cheaper alternative to comprehensive that lists only named perils (fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, mischief, and vehicle sinking/derailment), so glass breakage and animal strikes outside the list are not covered. Each covered auto can carry a different combination at a different deductible.

The liability side covers bodily injury and property damage the insured becomes legally obligated to pay because of a covered auto, plus defense, which is paid in addition to the limit. The BAP usually carries a single Combined Single Limit (CSL) rather than split limits, simplifying allocation between BI and PD. Covered pollution costs are limited: the BAP covers pollution that results from a covered auto accident only for fuel/lubricants/fluids needed for the auto's operation, not for cargo being hauled, which is why pollution endorsements exist.

Key exclusions mirror the PAP but adapt to commercial use: expected or intended injury, contractual liability beyond an insured contract, workers compensation obligations, injury to employees (which belongs to workers compensation), property in the insured's care/custody/control, and racing. The care, custody, or control exclusion is heavily tested: damage to a customer's auto left with a repair shop is not BAP property damage; it needs garagekeepers.

Worked split example: a covered auto with a $100,000 CSL injures two people ($60,000 and $50,000 in damages) and damages a fence ($8,000). Total is $118,000 but the CSL caps payment at $100,000 across all bodily injury and property damage combined, unlike split limits which would cap each category separately. Understanding that a CSL is one shared pot is a frequent limit question.

Key Takeaways

Business Auto liability typically uses a single Combined Single Limit covering bodily injury and property damage together, with defense outside the limit. Physical damage offers collision, the broader comprehensive, and the narrower specified-causes-of-loss, each at its own deductible. Animal strikes and theft are comprehensive; impact and overturn are collision; and property in the insured's care needs garagekeepers because the care-custody-control exclusion removes it from the BAP.
