Personal Auto Policy Structure and Endorsements
The ISO Personal Auto Policy (PP 00 01) is organized into six lettered parts, and the exam expects you to know exactly what each part does. Part A is Liability, paying bodily injury and property damage the insured is legally obligated to pay, subject to exclusions and either split limits or a single combined limit. Part B is Medical Payments, a small no-fault coverage for occupants. Part C is Uninsured/Underinsured Motorists, which substitutes for a negligent driver who has no insurance or not enough. Part D is Damage to Your Auto, split between Collision and Other Than Collision (comprehensive), with a Transportation Expenses benefit. Part E lists the insured's duties after an accident or loss, and Part F contains general provisions such as the rule coordinating two or more auto policies issued to the same insured. Several mechanics inside these parts are exam staples. A newly acquired auto gets automatic coverage only if reported within the stated window. The racing exclusion knocks out both liability and physical damage for any vehicle inside a facility designed for racing when the purpose is competing in, practicing for, or preparing for an organized speed contest — a much broader sweep than students expect. Part C carries its own machinery: the UM trigger requires a legally uninsured at-fault driver, while UIM pays only the difference between the insured's covered damages and what the at-fault driver's insurer actually paid. Combining UM limits from multiple vehicles on one policy is intra-policy stacking; combining limits across different policies is inter-policy stacking, and many states let insurers attach anti-stacking language. Endorsements round out the picture: PP 03 23 covers miscellaneous vehicle types such as motorcycles, the Named Non-Owner endorsement covers a driver who owns no car, PP 03 21 Drive Other Car extends coverage for furnished autos, PP 03 02 Rental Reimbursement pays substitute transportation subject to both a per-day limit and a per-loss aggregate, and PP 03 35 Auto Loan/Lease Gap pays the difference between actual cash value and the outstanding loan balance after a total loss.

The PAP has six parts: A Liability, B Med Pay, C UM/UIM, D Physical Damage, E Duties, F Provisions
Each part is a self-contained coverage grant or set of conditions; Part D splits into Collision and Other Than Collision, and Part F coordinates multiple policies on the same insured.
Why the exam cares: The exam constantly asks which part responds to a fact pattern, so mapping the six parts is the fastest scoring skill in this section.
A newly acquired auto must be reported within 14 days to keep automatic coverage
The PAP extends coverage automatically to a replacement or additional vehicle for a limited period, after which the insured must have asked the insurer to add it.
Why the exam cares: Questions test whether a loss on an unreported new car weeks after purchase is covered — the 14-day reporting window decides the answer.
The racing exclusion bars Part A and Part D coverage, including practice and preparation
Loss is excluded for any vehicle inside a facility designed for racing when used to compete in, practice for, or prepare for any prearranged or organized racing or speed contest.
Why the exam cares: Examiners bait candidates with track-day scenarios; the trap is thinking only the actual race, or only liability coverage, is excluded.
UIM pays covered damages minus what the at-fault driver's insurer already paid
With $100,000 UIM limits, $90,000 in damages, and a $25,000 at-fault payment, UIM owes $65,000. Part C also contains consent-to-settle and trust-agreement conditions protecting the insurer's subrogation rights.
Why the exam cares: UIM offset math is one of the most common calculation questions in personal auto testing.
Rental Reimbursement pays the per-day rate but never more than the per-loss aggregate
PP 03 02 pays substitute transportation after a covered Part D loss; payment stops when the car is repaired or replaced, and the per-loss cap controls even if days times rate exceeds it.
Why the exam cares: Exam math questions multiply days by the daily rate and expect you to apply the aggregate cap, not the raw product.
Numbers to memorize
- 14 days — reporting window for a newly acquired auto to retain automatic PAP coverage
- UIM payment = covered damages − amount paid by the at-fault driver's insurer, up to the UIM limit
- Rental reimbursement = days × per-day limit, capped at the per-loss aggregate (e.g., 35 × $40 = $1,400 but a $1,200 cap pays $1,200)
Common traps
- Confusing the UM trigger with UIM mechanics — UM requires an uninsured at-fault driver, while UIM applies an offset against what the underinsured driver's carrier paid.
- Confusing intra-policy stacking with inter-policy stacking — intra combines limits of multiple vehicles on one policy; inter combines limits across separate policies.
- Thinking the racing exclusion applies only during actual competition — practice and preparation at a racing facility are excluded too, for both liability and physical damage.
- Assuming rental reimbursement pays the full per-day amount for every shop day — the per-loss aggregate cap and the repair-completion cutoff both limit payment.
Before answering any PAP question, name the part (A through F) the fact pattern lives in — most wrong answers quote a real rule from the wrong part.
