- Forty-nine states and the District of Columbia require it, each with its own minimum.
- If you cause more damage than your limits cover, you are responsible for the difference.
- Liability coverage averaged $813 per insured vehicle in 2024, according to the NAIC.
In this guide
Liability car insurance pays for the harm you cause to other people when you are at fault in a crash: their injuries and the damage to their vehicles and property. It is the part of a policy that the law requires in nearly every state, and it is the only part that never pays you.
The two parts of liability coverage
Bodily injury liability covers injuries you cause to someone else. It also applies when you or a family member listed on your policy drives another person's car with permission 1.
Property damage liability covers damage you cause to things that belong to others: usually their car, but also fences, buildings, signs and parked vehicles.
Liability policies typically also provide a legal defense if you are sued over a covered crash.
| Bodily injury liability | Property damage liability | |
|---|---|---|
| Pays for | Other people's medical costs and related losses | Repair or replacement of other people's vehicles and property |
| Pays whom | The people you injured | The owners of what you damaged |
| Covers you or your car | No | No |
| Deductible | None | None |
How to read liability limits
Limits are usually written as three numbers separated by slashes. Texas, for example, requires 30/60/25 2:
| Number | Meaning in 30/60/25 |
|---|---|
| First | Up to $30,000 for injuries to any one person |
| Second | Up to $60,000 for all injuries in one accident, however many people are hurt |
| Third | Up to $25,000 for property damage in one accident |
The first number caps the second. If one person has $50,000 of medical bills, a 30/60 policy pays $30,000 for that person, even though the per-accident figure is higher.
Example
You carry 30/60/25 and cause a crash. One driver has $45,000 in medical bills and their car, worth $32,000, is a total loss. Your policy pays $30,000 toward the injuries and $25,000 toward the car. The remaining $15,000 in medical costs and $7,000 for the car can be claimed from you personally.
Some policies use a single combined limit instead, such as $300,000 for all injuries and property damage in one accident.
What states require
Forty-nine states and the District of Columbia require drivers to carry liability insurance. New Hampshire is the exception, although it still requires drivers to be able to pay for damage they cause 3. Each state sets its own minimum.
| State | Minimum required |
|---|---|
| California | $30,000 per person and $60,000 per accident for injuries, $15,000 for property damage 4 |
| Texas | $30,000 per person and $60,000 per accident for injuries, $25,000 for property damage 2 |
| Florida | Proof of personal injury protection and property damage liability to register a vehicle 5 |
Florida shows how much state rules can differ. Its registration requirement centers on personal injury protection, which pays for the policyholder's own injuries, together with property damage liability 5.
Requirements change. California's current limits appear on its motor vehicle agency's website 4, and your own state's insurance department or motor vehicle agency is the place to confirm yours.
Why the minimum may not be enough
State minimums define what is legal, not what a serious crash costs. A new vehicle can be worth more than many states' property damage minimums, and hospital treatment for a serious injury can exceed a per-person limit quickly.
When damage exceeds your limits, the gap does not disappear. The injured person can pursue you for it, which can put savings, property and future wages at risk.
How much liability coverage to carry
There is no official formula, but the reasoning is straightforward: carry enough that a serious claim is paid by your insurer and not by you.
| Limits | Who typically chooses them |
|---|---|
| State minimum | Drivers seeking the lowest legal price who have few assets to protect |
| 50/100/50 | Drivers who want a margin above the minimum at modest extra cost |
| 100/300/100 | Drivers with savings, a home or a steady income to protect |
| 250/500/100 or higher | Drivers with substantial assets, often combined with an umbrella policy |
These are commonly offered combinations, not rules. Three questions help you choose:
- What could you lose? Add up savings, home equity and other assets. Many people set their per-accident limit at or above that figure.
- What does the next step up cost? Ask for the price at two or three levels. The increase is often small compared with the extra protection.
- Do you need more than a car policy offers? A personal umbrella policy adds liability protection above your auto and home limits, and usually requires you to carry certain underlying limits first.
It also makes sense to carry uninsured and underinsured motorist coverage at the same limits, so that you are protected as well as the people you might injure.
What liability coverage costs
The NAIC reports that liability coverage averaged $813 per insured vehicle in 2024, up from $631 in 2020 6. In the NAIC's data, that figure includes related coverages such as personal injury protection, medical payments and uninsured motorist coverage.
State averages for 2024 ranged from about $372 in North Dakota to about $1,391 in Florida 6. The NAIC warns that such comparisons are affected by differences in state laws and in the limits drivers choose.
Your own price depends on the factors covered in how much car insurance costs, and on the limits you select.
Liability-only or more?
A liability-only policy is the least expensive way to drive legally. It leaves two gaps: your own car and your own injuries. Whether to fill them depends on your car's value and your finances.

The bottom line
Liability coverage protects other people from your mistakes and protects you from the bill. Read your three numbers, compare them with what you own and earn, and price the next level up before settling for the minimum. The main car insurance guide shows how liability fits with the other coverages.
Frequently asked questions
- What does liability car insurance not cover?
- It does not cover damage to your own car, your own medical bills or theft of your vehicle. Those are covered by collision, comprehensive, and personal injury protection or medical payments coverage.
- What does 100/300/100 mean?
- It means up to $100,000 for each person you injure, up to $300,000 in total for all injuries in one accident, and up to $100,000 for property damage in one accident.
- Is liability-only insurance enough?
- It satisfies the law in almost every state. Whether it is enough depends on whether you could afford to repair or replace your own car and on how your limits compare with what you could lose in a lawsuit.
- Do I pay a deductible on a liability claim?
- No. Deductibles apply to coverage for your own vehicle, such as collision and comprehensive. When someone claims against your liability coverage, the insurer pays from the first dollar, up to your limit.
- What happens if the damage is more than my liability limit?
- Your insurer pays up to the limit, and the injured party can seek the remainder from you personally. That is the main reason to consider limits above the state minimum.
