12.2 Commercial Auto Liability and Physical Damage

Liability Coverage

The BAP liability insuring agreement promises to pay sums the insured becomes legally obligated to pay as bodily injury (BI) or property damage (PD) caused by an accident and resulting from the ownership, maintenance, or use of a covered auto. It also covers pollution in limited situations and pays defense costs outside the limit (in addition to the limit of insurance).

Commercial auto almost always uses a combined single limit (CSL) — one dollar amount per accident for all BI and PD combined — rather than split limits.

Split limits vs. combined single limit

Split limits are written as three numbers, e.g., 100/300/50: $100,000 per person BI, $300,000 per accident BI, $50,000 per accident PD. A CSL of $500,000 instead provides one flexible pool.

Worked example: An at-fault insured injures two people ($120,000 and $90,000) and damages property worth $70,000.

• Under 100/300/50 split limits: person one is capped at $100,000; person two collects $90,000; PD is capped at $50,000 — total paid $240,000, leaving $40,000 uncovered.
• Under a $500,000 CSL: all $280,000 is paid in full because there is one shared limit.

Physical Damage Coverage

Physical damage to the covered auto is written under three options:

• Comprehensive — all direct loss except collision and overturn (fire, theft, hail, glass, animal strike).
• Specified causes of loss — a narrower, cheaper named-peril alternative (fire, lightning, theft, windstorm, flood, etc.).
• Collision — impact with another object or overturn.

Loss is settled at actual cash value (ACV) or cost to repair, whichever is less, minus the deductible. ACV equals replacement cost minus depreciation.

ACV worked example

A box truck with a replacement cost of $60,000 has depreciated 40%. Its ACV is $60,000 × (1 − 0.40) = $36,000. After a covered collision deemed a total loss with a $1,000 collision deductible, the insurer pays $36,000 − $1,000 = $35,000. The deductible applies per occurrence, not per coverage year.

Comprehensive vs. Specified Causes of Loss

The three physical-damage options form a price-and-breadth ladder. Comprehensive is open-peril for everything except collision and overturn, so theft, fire, falling objects, vandalism, glass breakage, flood, and hitting an animal are all covered. Specified Causes of Loss is a cheaper named-peril alternative listing fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, mischief, and the sinking or derailment of a transporting conveyance - notably it does not cover glass breakage from a road hazard or hitting an animal, which surprises insureds who chose it to save premium.

Collision covers impact with another object or overturn regardless of fault.

Liability Exclusions and Supplementary Payments

BACF liability excludes expected or intended injury, contractual liability beyond an insured contract, workers compensation and employer's liability, damage to property in the insured's care, custody, or control, and pollution except in narrow auto-related circumstances. Like the personal auto policy, the BACF pays supplementary payments - defense costs, bail bonds up to a stated amount, the cost of appeal bonds, prejudgment interest, and reasonable expenses the insured incurs at the insurer's request - in addition to the limit of insurance.

Because defense is outside the limit, a long-tail liability suit can cost the insurer far more than the policy's stated combined single limit, a key reason businesses also buy a commercial umbrella over the BAP.

Towing, rental reimbursement, and loss-of-use add-ons

The physical-damage section can be broadened with towing and labor, rental reimbursement (transportation expenses), and for trucks a loss-of-use / downtime option. After a covered physical-damage loss, rental reimbursement pays a daily amount up to a cap to keep the business operating while the covered auto is repaired - a meaningful coverage for a single-vehicle operation whose revenue stops if the truck is off the road. These are scheduled per auto and only apply when the triggering loss is itself a covered comprehensive or collision loss.

Stated amount, agreed value, and total-loss settlement

Physical damage normally settles at the lesser of ACV or cost to repair, but two alternatives appear on the exam. A stated amount provision caps recovery at the lower of ACV, repair cost, or the dollar amount the insured stated at binding - it is a premium-control device, not a guarantee. Agreed value (less common on commercial auto) fixes the payable amount in advance, useful for specialty or antique vehicles whose ACV is hard to establish. When repair cost approaches or exceeds ACV, the insurer declares a constructive total loss, pays ACV minus the deductible, and takes the salvage.

Distinguishing these settlement bases - and remembering that the standard basis is the lesser of ACV or repair - resolves many commercial-auto physical-damage questions.

Exam Tip: A CSL pays more flexibly than split limits in a multi-claimant accident; physical-damage settlement is the lesser of ACV or repair cost minus the deductible; and Specified Causes of Loss is cheaper than Comprehensive precisely because it drops glass-breakage and animal-strike coverage.
