Key Takeaways

  • Part A provides third-party coverage for bodily injury (BI) and property damage (PD) caused by the insured
  • Liability limits are expressed as SPLIT LIMITS (e.g., 100/300/100) or as a Combined Single Limit (CSL)
  • Split limits: First number = BI per person, Second = BI per accident, Third = PD per accident
  • Defense costs are paid IN ADDITION to policy limits — insurer has duty to defend even groundless claims
  • State minimum liability limits vary widely — Florida requires only 10/20/10, while Alaska requires 50/100/25

Part A: Liability Coverage

Part A is the most important coverage in the PAP — it protects you financially when you're legally responsible for injuring others or damaging their property.

What Part A Covers

Third-party coverage for damages you're legally liable for:

CoverageWhat It Pays For
Bodily Injury (BI)Medical expenses, lost wages, pain and suffering, death
Property Damage (PD)Damage to other people's property (vehicles, buildings, etc.)

Understanding Liability Limits

Split Limits

The most common way to express auto liability limits:

Format: BI per person / BI per accident / PD per accident

Example: 100/300/100

  • $100,000 — Maximum BI per person
  • $300,000 — Maximum BI per accident (all persons combined)
  • $100,000 — Maximum PD per accident

How Split Limits Work

Scenario: You cause an accident injuring 4 people and damaging a car.

Injured PersonMedical BillsPolicy PaysGap
Person 1$150,000$100,000$50,000
Person 2$80,000$80,000$0
Person 3$90,000$90,000$0
Person 4$50,000$30,000$20,000
Total BI$370,000$300,000$70,000
Property Damage$15,000$15,000$0

Key Points:

  • Person 1 is limited to $100,000 (per-person limit)
  • Total BI is limited to $300,000 (per-accident limit)
  • Person 4 only gets $30,000 (what remains of the $300,000)

Combined Single Limit (CSL)

One limit covering ALL damages:

Example: $500,000 CSL

  • Covers any combination of BI and PD
  • More flexible than split limits
  • Often preferred by higher-net-worth individuals

State Minimum Liability Requirements

Every state (except NH) requires minimum liability coverage:

StateMinimum LimitsNotes
California15/30/5Lowest PD in nation
Florida10/20/10Very low limits
Texas30/60/25Higher than most
New York25/50/10Moderate
Alaska50/100/25Highest state minimum

Warning: State minimums are typically INADEQUATE. A serious accident can easily exceed $100,000 in damages.
