In brief

Car insurance is not one fixed package but a set of separate coverages — liability, collision, comprehensive, medical payments and more — that drivers select individually. This guide explains what each coverage pays for, which ones a state or lender may require, and how liability limits and deductibles affect your bill, based on guidance from the NAIC, the Insurance Information Institute and the CFPB.

What Car Insurance Is Actually Built From

A car insurance policy is a bundle of separate coverages that a buyer picks one by one, not a single standardized product, according to guidance published by the National Association of Insurance Commissioners (NAIC) and the Insurance Information Institute (Triple-I). Liability coverage — split into bodily injury liability and property damage liability — pays for the injuries and property damage a driver causes to other people, while it does not pay for the policyholder's own car or injuries, per the NAIC.

Most states require drivers to carry liability insurance before they can legally operate a car, the Triple-I notes. Other coverages, including collision, comprehensive, medical payments and uninsured motorist protection, are optional under state law but can be required by a lender or lease company while a loan is outstanding.

The Main Coverages, Side by Side

Common car insurance coverages and what they do
CoverageWhat it pays forRequired?Typical deductible
Liability (bodily injury + property damage)Injuries and property damage you cause to othersRequired in most states, per the Triple-INo deductible; limits are often written as numbers such as 25/50/25, per Progressive
CollisionRepairs to your own car after it hits another vehicle or an objectNot required by state law, but often required by lenders while a loan or lease is active, per the Triple-I$250–$1,000, per the Triple-I
ComprehensiveDamage to your own car from theft, weather, vandalism or animal strikesOften lender-required alongside collision, per the Triple-I and NAIC$100–$300, per the Triple-I
Medical payments / PIPMedical treatment for the driver and passengers, regardless of faultOptional in most states, per the Triple-ISet per policy; no deductible noted by the NAIC
Uninsured/underinsured motoristYour costs when the at-fault driver has no insurance or not enoughOptional in most states, per the Triple-IVaries by insurer
Gap insuranceThe difference between a totaled car's cash value and the remaining loan balanceOptional add-on usually offered by the lender, per the CFPBNot applicable

Liability limits are usually written as three numbers, such as 25/50/25, Progressive explains. The first number is the maximum paid per injured person, the second is the maximum paid for all injuries in one accident, and the third is the maximum paid for property damage in that accident — so a 25/50/25 policy caps bodily injury payouts at $25,000 per person and $50,000 per accident, and property damage at $25,000.

Steps to Choose the Right Coverage

  1. Look up your state's minimum required liability limits before comparing quotes, since minimums differ by state, per the NAIC.
  2. Decide how much liability coverage to buy above that minimum; the NAIC advises buying as much liability coverage as a driver can reasonably afford, to protect personal assets.
  3. Check whether a lender or lease requires collision and comprehensive coverage — financing arrangements commonly make both mandatory until the loan is paid off, per the Triple-I.
  4. Pick a deductible for collision and comprehensive that you could pay out of pocket; a higher deductible lowers the premium, per the NAIC.
  5. Add medical payments/PIP and uninsured/underinsured motorist coverage if you want protection for your own injuries or for accidents caused by drivers who are uninsured or underinsured, per the NAIC and Triple-I.
  6. If the loan balance on the car is higher than its current value, ask about gap insurance, an optional product that covers that difference if the car is totaled or stolen, per the CFPB.
  7. Request quotes from several insurers using identical coverage types and limits so the prices can be compared fairly, and check each insurer's record with the state insurance department, per the NAIC.
  8. Review the policy again whenever circumstances change, such as paying off a loan, buying a different car, or moving, per the NAIC.

Insurance Issues Specific to Financed Cars

When a car is financed or leased, the lender may offer or require additional insurance-related products. The CFPB describes gap insurance as an optional add-on covering the gap between a car's cash value and the loan balance, and credit insurance as a separate optional product that keeps loan payments current if the borrower dies, loses a job, or becomes disabled.

If a driver's own policy lapses, a lender may add force-placed insurance, which the CFPB says protects the lender and the vehicle but not the driver, with the cost sometimes folded into the loan. A related product, vendor's single interest (VSI) insurance, also protects the lender's financial interest in the car. The CFPB notes that loan terms are generally negotiable, and suggests drivers ask the lender whether VSI insurance can be waived or canceled once they obtain their own coverage.

A deductible is the amount of money you agree to pay prior to the insurance company making any payment on a loss.

Questions

What does a liability limit like 25/50/25 mean?
Per Progressive, the first number is the maximum paid per injured person, the second is the maximum paid for all injuries in one accident, and the third is the property-damage maximum for that accident — so 25/50/25 means up to $25,000 per injured person, $50,000 per accident for injuries, and $25,000 for property damage.
Do I have to buy collision and comprehensive coverage?
State law generally does not require them, but the Triple-I notes that lenders commonly require both while a car loan or lease is active; an owner with no loan can choose to skip them.
What is gap insurance and who needs it?
According to the CFPB, gap insurance is an optional add-on that covers the difference between a car's cash value and the remaining loan balance if the car is totaled or stolen, which can matter for buyers who owe more than the car is currently worth.
How does a deductible affect my premium?
The NAIC defines a deductible as the amount a policyholder pays before the insurer pays a claim, and notes that choosing a higher deductible lowers the premium; the Triple-I adds that typical collision deductibles run $250–$1,000 and comprehensive deductibles $100–$300.
What happens if my coverage lapses while I still have a car loan?
The CFPB says the lender may add force-placed insurance, which protects the vehicle and the lender's financial interest but not the driver, with the cost sometimes added to the loan balance.
