7.1 Part D Coverage for Damage to Your Auto

Part D: Coverage for Damage to Your Auto

Part D of the Personal Auto Policy (PAP) is the first-party physical damage section. It is built on the Insurance Services Office (ISO) Personal Auto Policy form PP 00 01, with the current widely tested edition being the PP 00 01 09 18. Part D pays the named insured for direct and accidental loss to a covered auto, regardless of who was at fault, subject to a deductible. This is property coverage on your own vehicle, distinct from the Part A liability that protects others.

Collision vs. Other-Than-Collision

Part D splits physical damage into two perils. Collision is the upset (overturn) of your covered auto or its impact with another vehicle or object. Other-Than-Collision (OTC), also called comprehensive, covers almost everything else: fire, theft, vandalism, falling objects, hail, flood, glass breakage, and contact with a bird or animal. Each is bought separately and each carries its own deductible.

Classifying a loss correctly is a frequent exam trap. Hitting a deer is OTC, not collision, because animal contact is specifically listed under other-than-collision. Swerving to avoid a deer and striking a guardrail is collision. A tree falling on a parked car is OTC; driving into that same tree is collision.

Limit of Liability and Actual Cash Value

Part D has no stated dollar limit. The insurer pays the lesser of the Actual Cash Value (ACV) of the property at the time of loss or the cost to repair or replace it with like kind and quality, minus the deductible. ACV equals replacement cost minus depreciation. Because vehicles depreciate, ACV is usually well below the original price.

Worked example: A car has an ACV of $14,000. Repairs after a collision are estimated at $9,500, with a $500 collision deductible. The insurer pays the lesser figure ($9,500) minus $500 = $9,000.

Total-loss example: If that same $14,000 ACV car is destroyed and repairs would cost $16,000, the loss is settled on ACV: $14,000 minus the $500 deductible = $13,500. The insurer never pays more than ACV, which is why low-value cars are often "totaled" at modest repair costs.

Transportation Expenses

Part D provides a small transportation expenses benefit, commonly $30 per day up to $900 under unendorsed forms, paying for a rental and certain loss-related expenses after a covered theft (after a 48-hour waiting period) or other covered loss.

Additional Coverages, Conditions, and Traps

Beyond the basic ACV settlement, ISO Part D (form PP 00 01 09 18) adds several smaller coverages and conditions that the exam tests directly. The no-benefit-to-the-bailee provision means a repair shop or carrier holding your vehicle cannot claim coverage under your policy. The appraisal condition lets either the insured or the insurer demand independent appraisers (and an umpire) when they disagree on the amount of a physical-damage loss, while coverage questions remain for the courts.

The insurer's right to choose how to settle (repair, replace, or pay ACV) and to use non-original-equipment (aftermarket) parts is a common point of dispute and is disclosed on the declarations. Part D also excludes electronic equipment not permanently installed, custom furnishings, and loss due to wear and tear, freezing, mechanical breakdown, or road damage to tires (unless caused by a covered total theft).

Worked example (betterment/depreciation trap): A 6-year-old vehicle needs a new transmission after a covered collision. Because the engine/transmission failed from impact, Part D pays; but had the transmission simply worn out, the mechanical breakdown exclusion would deny the claim. The cause of loss, not the damaged part, controls coverage.

Deductibles, Total-Loss Settlement, and Stated-Amount Traps

Each Part D peril (collision and other-than-collision) carries its own deductible, so a single event can never apply two deductibles, but two separate losses each trigger a deductible. When a vehicle is a total loss, the insurer settles at ACV and may take the salvage; gap coverage (the difference between ACV and a loan/lease balance) is not in the base form and must be added by endorsement — a frequent exam trap for financed vehicles that depreciate faster than the loan.

For specialized or collectible autos, a stated-amount or agreed-value basis can replace ACV, but the unendorsed PAP always pays the lesser of ACV or repair/replacement cost. The exam also tests that diminished value (a car's reduced resale value after a quality repair) is generally not recoverable under the standard PAP physical-damage grant. Knowing that ACV equals replacement cost minus depreciation, that gap is excluded by default, and that each peril has a separate deductible covers the most common Part D math questions.
