Part D Exclusions and Part E - Duties After an Accident or Loss
Key Takeaways
- Part D excludes losses to electronic equipment not permanently installed, custom furnishings, and certain trailers/camper bodies unless declared, plus wear and tear, freezing, mechanical breakdown, and road damage to tires
- The public-or-livery conveyance exclusion removes coverage when the auto is used to carry persons or property for a fee (taxi/delivery), with a carve-out for share-the-expense car pools
- War, nuclear hazard, racing, and destruction by a governmental authority are Part D exclusions tested as broad catastrophe/illegal-use bars
- Part E imposes general duties (prompt notice, cooperation, proof of loss) and physical-damage-specific duties (protect the auto from further loss, allow inspection, permit appraisal)
- Failure to perform Part E duties can prejudice the insurer and provide grounds to deny or reduce a claim
Why exclusions matter on the exam
Physical-damage exclusions in Part D of the ISO Personal Auto Policy (PP 00 01) are heavily tested because they convert a seemingly covered loss into an uncovered one. The exam wants you to recognize the fact pattern and pick the exclusion - not assume that any damage to the auto is paid.
The candidate should read each exclusion as the answer to a question: under what circumstance does Part D refuse to pay even though the vehicle is damaged?
Key Part D exclusions
| Excluded loss | Exam meaning |
|---|---|
| Public or livery conveyance | No coverage while carrying persons/property for a fee (taxi, ride-hail period, paid delivery); share-the-expense car pools are NOT excluded |
| Wear and tear, freezing, mechanical or electrical breakdown | Maintenance and gradual deterioration are not fortuitous losses; tire road damage excluded unless caused by a covered cause |
| Electronic equipment not permanently installed | Aftermarket radios, sound, navigation, or radar detectors not factory-installed are limited or excluded |
| Custom furnishings/equipment in pickups/vans | Special carpeting, murals, bars, height-extending roofs need a Customizing Equipment endorsement |
| War, nuclear hazard, radioactive contamination | Broad catastrophe bars common to all parts |
| Racing/speed contest | Damage on a track or in a prearranged race is excluded |
| Government destruction/confiscation | Seizure by lawful authority is not a covered peril |
| Camper body/trailer not shown in Declarations | Must be declared (with exception for newly acquired) |
The public-or-livery trap
The most-tested Part D exclusion is the public or livery conveyance bar. If the covered auto is being used to carry persons or property for a fee, Part D will not respond. This is why personal auto policies do not cover ride-hailing or paid-delivery activity without a special endorsement or a commercial policy.
Carve-out: a share-the-expense car pool is expressly not excluded. Sharing gas money with coworkers on a commute is still personal use. The trap distinguishes profit-seeking livery from cost-sharing. The previously discussed Transportation Network Company periods sit on top of this national rule but are governed by separate state law and endorsements.
Part E: Duties After an Accident or Loss
Part E is a condition, not a coverage. Conditions are duties the insured must satisfy to enforce the contract. Part E has two layers: duties owed for any loss, and additional duties owed for a Part D physical-damage loss.
General duties (any loss):
- Prompt notice to the insurer of how, when, and where the accident or loss happened, with names and addresses of injured persons and witnesses.
- Cooperate with the insurer in the investigation, settlement, or defense.
- Forward any legal papers (summons, demand) promptly.
- Submit to physical exams and examinations under oath when reasonably required, and authorize the insurer to obtain medical and other relevant records.
- Submit a proof of loss when required by the company.
Additional Part E duties for physical-damage losses
When a Part D loss occurs, the insured must also:
- Take reasonable steps after a loss to protect the auto and its equipment from further loss. The insurer will pay reasonable expenses incurred to do so. Leaving a wrecked car exposed so it is then stolen or rained-in can reduce recovery.
- Promptly notify the police if the auto is stolen.
- Permit the insurer to inspect and appraise the damaged property before its repair or disposal.
These duties exist so the insurer can verify the loss, control salvage, and prevent inflated or fraudulent claims.
Consequences of breaching Part E
Because Part E duties are policy conditions, a material failure that prejudices the insurer can support a denial or reduction of the claim. Common exam fact patterns:
- Insured repairs or junks the car before the adjuster inspects it - insurer cannot appraise, claim may be denied or limited.
- Insured fails to report a theft to police - statutory and policy duty breached.
- Insured ignores a lawsuit served on them and does not forward the summons - prejudices the insurer's defense duty under Part A.
The exam answer is usually that the insurer may deny or reduce payment to the extent it was prejudiced, not that the entire policy is automatically void.
An insured uses her personal auto to deliver restaurant orders for pay several nights a week. While delivering, she collides with a guardrail. Why might Part D deny the physical-damage claim?
After a covered collision, the insured has the car fully repaired and the parts discarded before notifying the insurer or allowing inspection. What is the most likely outcome under Part E?
Duties After a Loss and the Consequence of Breach
Part E imposes duties whose breach can defeat an otherwise valid claim. The insured must promptly notify the insurer, cooperate in investigation and any suit, and submit proof of loss when asked. For physical-damage claims the insured must also protect the auto from further loss, permit inspection and appraisal, and report theft to police.
The consequence is the testable point: if a breach of these duties prejudices the insurer's ability to investigate or defend, the insurer may deny or reduce the claim. The exam contrasts this with the public-or-livery conveyance exclusion (carrying persons or property for a fee, with a car-pool carve-out) and the broad bars for racing, war, nuclear hazard, and government destruction — all situations where coverage never attached in the first place rather than being lost through a duty breach.
After a covered theft, an insured waits three weeks to report it, fails to notify police, and the vehicle is never recovered, hampering the investigation. What is the likely Part E result?
What Part D Will Not Pay For
Beyond use-based and catastrophe exclusions, Part D removes several categories of property from physical-damage coverage. Excluded or limited items include electronic equipment not permanently installed (and the media/accessories for it), custom furnishings or equipment in a pickup or van unless declared, awnings, citizens-band radios, and similar equipment, and certain trailers, campers, or motor homes not described on the declarations. Coverage for these usually requires a specific endorsement and an added premium.
Part D also excludes wear and tear, freezing, mechanical or electrical breakdown, and road damage to tires — these are maintenance or non-fortuitous losses, not sudden accidents, echoing the fortuitous-loss principle from the fundamentals chapter. The practical exam pattern is to present a gradual or maintenance-type failure (a worn transmission, a slowly leaking seal) and ask whether physical-damage coverage responds; the answer is no, because the loss is not the sudden, accidental kind Part D insures.
