7.1 Part D - Coverage for Damage to Your Auto

Part D - Coverage for Damage to Your Auto

Part D of the ISO Personal Auto Policy (PP 00 01 09 18) is the first-party property coverage that pays to repair or replace your covered auto and any non-owned auto you are operating. Unlike Part A liability, which protects others, Part D protects your own vehicle regardless of fault. Exam writers test the distinction sharply: Part A = third-party, Part D = first-party physical damage. Part D is the only part of the PAP that carries a deductible, and the only one that is genuinely optional in most states.

Part D splits into two named coverages: Collision and Other Than Collision (OTC), the latter historically called comprehensive. Each can be insured separately, and each carries its own deductible (commonly $250, $500, or $1,000). A lienholder almost always requires both.

Collision Coverage

The PAP defines collision as "the upset of your covered auto or its impact with another vehicle or object." The trigger is impact or rollover. Rear-ending another car, hitting a guardrail, striking a tree, or flipping the vehicle are all collision losses. Fault is irrelevant to whether collision pays - your own collision coverage responds even if you caused the crash, subject to the deductible.

Other Than Collision (Comprehensive)

OTC covers everything else: fire, theft of the entire vehicle, vandalism, malicious mischief, glass breakage, falling objects, explosion, earthquake, windstorm, hail, flood, riot, contact with a bird or animal, and missiles. The policy explicitly lists contact with a bird or animal under OTC - hitting a deer is comprehensive, not collision. This is a classic trap.

How Much Part D Pays - ACV and the Limit of Liability

The insurer's obligation is the lesser of: (1) the actual cash value (ACV) of the stolen or damaged property, or (2) the amount necessary to repair or replace the property with like kind and quality. From that figure the deductible is subtracted. The PAP pays ACV, not replacement cost - this is the single most-tested numeric concept in Part D.

ACV = Replacement Cost - Depreciation. A 6-year-old car is paid at its depreciated market value, never the cost of a new car. A betterment or full-replacement payout would require a separate endorsement.

Worked example: A covered auto with an ACV of $14,000 is totaled in a collision. The collision deductible is $500.

• Lesser of ACV ($14,000) or repair cost (not feasible - total loss) = $14,000
• Less deductible: $14,000 - $500 = $13,500 paid

If the same car had repairable damage of $4,200, the insurer pays $4,200 - $500 = $3,700, because repair cost is less than ACV.

Glass, Transportation Expenses, and Towing

Many insurers offer full glass coverage waiving the OTC deductible on glass-only claims; without it, glass is paid under OTC subject to the deductible. The base PAP also includes a modest Transportation Expenses provision: up to $30 per day, $900 maximum for a temporary substitute (rental) following a theft of the entire covered auto (after a 48-hour waiting period) or for loss of use following any other covered loss. These sub-limits are frequently quizzed - memorize $30/$900.

Towing and labor at the place of disablement is provided only if Towing and Labor Costs coverage (PP 03 03) is endorsed; it is not built into the base form. Candidates should distinguish loss-of-use transportation (built in, capped at $30/$900) from roadside towing (endorsement required) - the two are routinely swapped in distractor answers.

Finally, remember that each Part D coverage stands alone. An insured may carry Collision but decline OTC, or carry OTC with a lower deductible than Collision. When a vehicle is fully paid off, owners often drop both to save premium, accepting the depreciated value risk themselves - a real-world point examiners use to test understanding of why Part D is optional while Parts A and B are typically state-mandated.

Collision vs. Other Than Collision (Comprehensive)

Part D splits physical-damage protection into two perils that are bought and deductible-rated separately. Collision is impact with another vehicle or object, or overturn. Other Than Collision (Comprehensive) is virtually everything else — fire, theft, vandalism, glass breakage, flood, falling objects, and contact with a bird or animal (the classic deer strike).

The deer-strike classification is among the most tested facts in the whole auto unit: hitting an animal is comprehensive, but swerving to avoid an animal and striking a tree is collision. Each peril carries its own deductible, and the insurer pays the lesser of the ACV of the auto or the cost to repair, minus the deductible.

Limit of Liability, Betterment, and Loss of Use

Part D pays the lesser of (1) the actual cash value of the stolen or damaged property or (2) the amount necessary to repair or replace it with like kind and quality, in each case minus the applicable deductible and never above any stated limit. Because the standard is ACV, depreciation reduces the payout on an older vehicle, and a total loss is settled at the auto's ACV — which can be less than the loan balance unless gap coverage is added.

Two refinements appear on the exam. First, the insurer may reduce a repair payment for betterment when a new part materially improves a worn component, though many insurers waive small betterment amounts. Second, the standard PAP provides only limited transportation expense after a theft of the entire auto (for example $20 per day up to $600) and limited towing if that endorsement is purchased; broader rental reimbursement requires the Transportation Expenses/rental endorsement. Custom equipment beyond a small built-in amount must be specifically described to be covered.
