Liability Coverage: The Foundation of Any Policy
Liability insurance is the baseline requirement in almost every US state. It's designed to protect other people — not you — when you're at fault in an accident. It splits into two parts:
- Bodily injury liability: Pays for medical expenses, lost wages, and legal costs if you injure someone else in a crash.
- Property damage liability: Pays to repair or replace another person's vehicle or property you damage.
Policies express limits in a three-number format, such as 25/50/25, meaning $25,000 per injured person, $50,000 per accident total, and $25,000 for property damage. State minimums are often lower than what experts consider adequate for real-world accident costs. For a deeper look at what liability does and doesn't pay, see what liability coverage actually pays for.
State Minimums Are a Floor, Not a Recommendation
State-mandated liability minimums represent the legal baseline, not the coverage level most insurance professionals consider adequate. Medical costs and vehicle repair expenses have risen significantly over time, and a serious accident can exceed minimum limits quickly. Many drivers choose limits above state minimums to reduce their personal financial exposure.
Collision and Comprehensive: Protecting Your Own Vehicle
These two coverage types are often bundled together by lenders and often confused with each other — but they cover entirely different situations.
Collision coverage pays to repair or replace your vehicle after it collides with another car or object, regardless of who is at fault. If you back into a pole or get sideswiped on the highway, collision applies.
Comprehensive coverage covers losses that aren't the result of a collision — think hail damage, a fallen tree, flooding, fire, vandalism, or a deer strike. It also covers theft of the vehicle itself.
Both come with deductibles you choose when setting up the policy. If your car is financed or leased, your lender almost certainly requires both. For a side-by-side breakdown of how these two work in real scenarios, see comprehensive vs. collision coverage.
Check Your Lender's Requirements First
If you're financing or leasing a vehicle, your lender will typically require both collision and comprehensive coverage for the duration of the loan or lease. Dropping these coverages without the lender's consent may be a breach of your finance agreement. Review your loan documents or contact your lender before making any coverage changes.
Personal Injury Protection, MedPay, and Uninsured Motorist Coverage
Beyond liability and vehicle damage, several coverage types address medical costs and gaps caused by other drivers.
Personal Injury Protection (PIP) — required in no-fault states — pays medical expenses for you and your passengers after an accident, regardless of fault. It may also cover lost wages and rehabilitation costs. Medical Payments (MedPay) is a similar but narrower option available in at-fault states, covering medical bills for you and passengers without the wage or rehab components.
Uninsured/Underinsured Motorist (UM/UIM) coverage fills the gap when you're hit by a driver who has no insurance or whose limits aren't enough to cover your damages. According to the Insurance Research Council, roughly one in eight drivers on US roads is uninsured — making this coverage more relevant than many drivers realize.

Frequently Asked Questions
Most states require liability insurance at minimum — covering bodily injury and property damage you cause to others. A handful of states also mandate PIP or uninsured motorist coverage. Requirements vary significantly by state, so check your state's Department of Motor Vehicles or insurance commissioner for specifics.
Yes, but only if you carry comprehensive coverage. Liability and collision policies do not cover theft. Comprehensive covers vehicle theft as well as vandalism, weather events, and other non-collision losses.
A deductible is the amount you agree to pay out of pocket before your insurance covers the rest of a claim. For example, with a $500 deductible on a $3,000 repair, you pay $500 and your insurer pays $2,500. Higher deductibles generally mean lower premiums.
It depends on your car's value and your financial situation. If your vehicle is worth very little, paying for collision and comprehensive may cost more annually than the car is worth. That said, liability alone leaves you responsible for your own repair costs after any accident.
Without uninsured motorist (UM) coverage, you may have to pursue the at-fault driver personally, which is often difficult. UM coverage steps in to pay for your injuries and, in many states, property damage when the responsible driver has no insurance or not enough to cover your losses.
Yes. You can generally increase or decrease your coverage limits when you renew or update your policy, subject to state minimums. Higher limits provide more protection but cost more in premiums. A licensed insurance agent can walk you through the trade-offs for your specific circumstances.
