6.2 Part A Liability and Supplementary Payments

Key Takeaways

  • Part A pays BI/PD the insured is legally liable for and provides a duty to defend; defense costs are paid in addition to the limit.
  • Split limits (e.g., 100/300/50) cap BI per person/per accident and PD per accident; a CSL applies one combined limit per accident with no per-person cap.
  • Supplementary payments — defense costs, bond premiums, up to $250 bail, post-judgment interest, $200/day lost earnings — are paid above the policy limit.
  • Key exclusions include intentional acts, the insured's own/rented property, employee injuries, and public/livery use; car pools are an exception.

Part A: Liability Coverage and Supplementary Payments

Part A - Liability is the core of the Personal Auto Policy and the coverage Mississippi requires every motorist to carry. It pays damages an insured becomes legally responsible for because of an auto accident, covering both bodily injury (BI) and property damage (PD) to third parties. Part A also obligates the insurer to defend the insured, hiring and paying attorneys even for groundless or fraudulent suits.

The Insuring Agreement

The PAP insuring agreement reads that the insurer "will pay damages for bodily injury or property damage for which any insured becomes legally responsible because of an auto accident." Two ideas are tested repeatedly:

  1. Legal liability is required - Part A is third-party, fault-based coverage. There must be a legally liable insured.
  2. The duty to defend ends when limits are exhausted - once the insurer pays the limit in settlement or judgment, its obligation to defend that claim terminates.

Single Limit vs. Split Limits

Mississippi's financial-responsibility law is expressed in split limits of 25/50/25:

LimitAmountMeaning
BI per person$25,000Maximum for any one injured person
BI per accident$50,000Maximum for all bodily injury in one accident
PD per accident$25,000Maximum for property damage in one accident

A Combined Single Limit (CSL) instead provides one pooled amount (e.g., $100,000) for all BI and PD in an accident, giving more flexibility when one severe injury exceeds a per-person cap.

A Split-Limit Worked Example

Assume Mississippi minimum 25/50/25 limits. The insured causes an accident injuring three people - $30,000, $20,000, and $15,000 in BI claims - and causes $28,000 in property damage.

ClaimAmount ClaimedPolicy PaysReason
Person 1 BI$30,000$25,000Capped at $25k per-person limit
Person 2 BI$20,000$20,000Within per-person limit
Person 3 BI$15,000$5,000Per-accident $50k cap reached ($25k+$20k+$5k)
Property damage$28,000$25,000Capped at $25k PD limit

The insured personally owes the $5,000 BI shortfall, the $10,000 left for Person 3, and the $3,000 PD shortfall - $18,000 out of pocket. This example shows why agents recommend limits well above the state minimum and is a classic exam computation.

Out-of-State Coverage

Part F's out-of-state provision automatically raises the policy's liability limits to meet a higher compulsory or financial-responsibility limit of another state the insured drives into. A Mississippi 25/25 PD driver entering a state requiring 25/50/25 is treated as carrying the higher figures for that accident.

Supplementary Payments

Part A pays the following in addition to the limit of liability, so they do not erode the insured's coverage:

  • Up to $250 for bail bonds required because of a covered accident.
  • Premiums on appeal bonds and bonds to release attachments in a suit the insurer defends.
  • Interest accruing on a judgment after entry, until the insurer pays its share.
  • Up to $200 a day for loss of earnings (not other income) for attending hearings or trials at the insurer's request.
  • Other reasonable expenses incurred at the insurer's request.

Exam tip: Supplementary payments are extra - they are not subtracted from the policy limit. Bail bonds are capped at $250 and loss-of-earnings reimbursement at $200/day; memorize both figures.

Liability Exclusions Worth Knowing

Part A excludes intentional injury, liability assumed under contract beyond the insured's own fault, vehicles used to carry persons or property for a fee (ride-share without endorsement), and using a vehicle the insured does not own but has regular access to (the "furnished or available for regular use" exclusion). These exclusions reappear in Part B and Part D analyses.

Other Insurance and the Two-or-More Autos Rule

When more than one auto policy applies, Part A's Other Insurance clause makes coverage on a non-owned auto excess over any other collectible insurance. On the insured's owned auto, the PAP is primary. If two or more PAPs cover the same loss, each insurer pays its proportional share based on limits. This pro-rata/excess hierarchy is a common multi-policy exam scenario: the policy on the car being driven generally responds first, and the driver's own policy sits excess when driving someone else's vehicle.

Limits Apply Regardless of Number of Insureds or Claims

The PAP states that the limit of liability is the most the insurer will pay regardless of the number of insureds, claims made, vehicles or premiums shown, or vehicles involved. This anti-stacking-of-limits language prevents an insured from multiplying the per-accident BI limit by the number of covered persons. Watch for fact patterns implying that adding insureds or paying multiple premiums raises the per-accident cap - it does not.

Exam tip: A higher liability limit protects the insured's personal assets from a judgment. Mississippi's 25/50/25 is a floor, not a recommendation; the worked example above shows how quickly minimum limits are exhausted in a multi-injury crash, leaving the at-fault insured personally exposed for the excess.
