The short answer
Liability car insurance is the coverage that pays for the harm you cause to other people when you’re at fault in an accident — their injuries and their damaged property. It’s the one coverage nearly every state legally requires (all except New Hampshire), and it comes in two parts working together.
Here’s the catch worth knowing before anything else: liability insurance pays for everyone in the crash except you. Not your injuries, not your car. And the legal minimum most drivers carry was designed to satisfy the state — not to protect your savings if a serious accident goes past those limits. That gap is where this guide spends its time.
The two parts of liability coverage
| Coverage | Pays for | Does not pay for |
|---|---|---|
| Bodily Injury (BI) liability | Others’ medical bills, lost wages, and related costs when you’re at fault | Your own injuries (that’s PIP or MedPay) |
| Property Damage (PD) liability | Others’ vehicle, fence, mailbox, or building you damage | Your own vehicle (that’s collision) |
Because liability never pays for your own car, drivers who want that protection add collision and comprehensive coverage on top — the combination people call full coverage.
How to read the numbers (25/50/25 decoded)
Liability limits are written as three numbers, like 25/50/25. They’re just three dollar caps in thousands:
- $25,000 — the most BI paid for any one person injured
- $50,000 — the most BI paid for everyone injured in one accident, combined
- $25,000 — the most PD paid for property damage in one accident
So 25/50/25 means that if you injure three people in one crash, the policy pays up to $25,000 for each, but no more than $50,000 total — and up to $25,000 for the cars and property you damaged. Anything above those caps is not the insurer’s problem. It’s yours.
State minimums vary widely
Each state sets its own floor, and they’re not close to uniform. A few that show the range:
| State | Minimum liability limits | Note |
|---|---|---|
| Pennsylvania | 15/30/5 | Among the lowest |
| California | 30/60/15 | Raised in 2025 |
| New Jersey | 35/70/25 | Raised Jan 1, 2026 |
| North Carolina | 50/100/50 | Highest property-damage floor |
| Florida | 0/0/10 | No BI required — a PIP state |
Several states have been raising their minimums as accident costs climb, which tells you something: even lawmakers think the old floors were too low.
The state-minimum trap
This is the part that quietly ruins people, so it deserves a hard look.
Carrying your state’s minimum feels like being covered — you’re legal, you passed. But the minimum was set to let you drive, not to shield your finances. A single serious injury easily runs into six figures. If you cause a crash with $25,000 of BI coverage and the other driver’s hospital bill is $120,000, your insurer pays the first $25,000 — and you are personally on the hook for the remaining $95,000. The injured party can pursue your savings, your home equity, and even garnish future wages to collect.
That’s why the minimum is often the most expensive coverage you can buy: it’s cheap monthly and catastrophic once. The Insurance Information Institute recommends carrying 100/300/100 — $100,000 per person, $300,000 per accident, $100,000 property — precisely because that’s closer to what real accidents cost.
So how much do you actually need?
Cost tells the story better than advice. State-minimum liability averages roughly $726–$738 a year nationally. Bumping up to 50/100/50 averages about $829 — a modest increase for double or triple the protection. Moving toward the recommended 100/300/100 costs more, but the jump from minimum to solid coverage is usually smaller than people expect, because the first dollars of coverage are the priciest to insure.
A reasonable rule: carry enough BI to protect what you own. If your assets exceed your state minimum — and for most homeowners they do — the minimum leaves the gap exposed. If you want to see where liability ends and the rest of a policy begins, compare it against what full coverage car insurance actually includes.

FAQ
Does liability insurance cover my own car?
No. Liability pays only for the other party’s injuries and property. Your own car needs collision and comprehensive.
Is liability car insurance required?
Yes, in every state except New Hampshire — though a few states meet the requirement through other coverage like PIP.
What’s the difference between bodily injury liability and PIP?
BI pays others’ medical bills when you’re at fault; PIP (or MedPay) pays your own and your passengers’, regardless of fault.
What happens if damages exceed my liability limits?
You’re personally responsible for the excess. The injured party can pursue your assets and wages, which is why minimum limits are risky if you have anything to lose.
