Why Insurance Terminology Matters
Auto insurance policies are legal contracts, and the language in them carries real financial weight. Misreading a term like actual cash value versus replacement cost can mean thousands of dollars less than you expected when a claim is settled. This glossary is designed to give you a plain-language foundation before you read or purchase a policy.

Coverage Types and What They Pay For
Auto insurance is not a single blanket protection — it is a collection of individual coverage types, each with its own rules, limits, and deductibles. Here is a concise breakdown of the most common types you will encounter:
- Bodily Injury Liability (BI): Pays for injuries to others when you are at fault. Expressed per-person and per-accident (e.g., $50,000/$100,000).
- Property Damage Liability (PD): Covers damage you cause to someone else's vehicle or property.
- Personal Injury Protection (PIP): Required in no-fault states. Covers your medical expenses and sometimes lost wages regardless of fault.
- Medical Payments (MedPay): Similar to PIP but narrower in scope; covers medical costs for you and your passengers after an accident.
- Gap Insurance: If your car is totaled and you owe more on your loan than the vehicle's actual cash value, gap insurance covers the difference.
- Rental Reimbursement: Pays for a rental car while your vehicle is being repaired after a covered claim.
State Requirements Vary Widely
Each U.S. state sets its own minimum auto insurance requirements. Some mandate personal injury protection (PIP); others require uninsured motorist coverage. Always verify the specific rules for your state before purchasing a policy, and consult a licensed insurance agent if you have questions about your obligations.
