Liability car insurance pays for injuries and property damage you cause to others in an accident. The average bodily injury claim is $28,278, according to the Insurance Information Institute — yet the most common state minimum is just $25,000 per person. That $3,278 gap comes out of your own pocket.
Liability insurance is the foundation of every auto policy — and also the most misunderstood. Most drivers buy whatever minimum the state requires and assume they're covered. They're not. Here's how liability insurance actually works, what it covers, and why the standard advice to carry 100/300/100 could save your financial life.
This article is part of our complete guide to car insurance coverage types — for the full picture of every coverage available to you, start there.
What Liability Car Insurance Actually Covers
Liability coverage is split into two parts that protect you from very different risks:
Bodily injury liability (BI) pays for medical expenses, lost wages, pain and suffering, and legal costs if you injure someone in an accident. It covers the other driver, their passengers, pedestrians — anyone except you and your own passengers.
Property damage liability (PD) pays to repair or replace other people's vehicles and property you damage — cars, fences, mailboxes, storefronts. Again, this is for their stuff, not yours.
When you see coverage written as 25/50/25, that's the shorthand that tells you exactly what you have:
- $25,000 — maximum BI payout per injured person
- $50,000 — maximum BI payout per accident (total, all injured parties)
- $25,000 — maximum property damage payout
Liability coverage never pays for your own injuries or vehicle damage. If you cause an accident, you'll need collision coverage to repair your car and health insurance (or PIP/MedPay) to cover your medical bills. Learn how PIP coverage works and when it applies.
State Minimum Requirements: The Numbers Are Too Low
Every state except New Hampshire requires liability insurance. But "required" doesn't mean "sufficient." The table below shows current minimums for 15 major states — pay attention to how wide the range is.
| State | Min. BI Per Person | Min. BI Per Accident | Min. Property Damage | Recent Change? |
|---|---|---|---|---|
| North Carolina | $50,000 | $100,000 | $50,000 | Raised July 2025 |
| Maine | $50,000 | $100,000 | $25,000 | — |
| Virginia | $50,000 | $100,000 | $25,000 | Raised Jan 2026 |
| New Jersey | $35,000 | $70,000 | $25,000 | Raised Jan 2026 |
| California | $30,000 | $60,000 | $15,000 | Raised Jan 2026 |
| Texas | $30,000 | $60,000 | $25,000 | — |
| Utah | $30,000 | $65,000 | $25,000 | Raised Jan 2026 |
| Minnesota | $30,000 | $60,000 | $10,000 | — |
| Maryland | $30,000 | $60,000 | $15,000 | — |
| Colorado | $25,000 | $50,000 | $15,000 | — |
| New York | $25,000 | $50,000 | $10,000 | — |
| Michigan | $50,000 | $100,000 | $10,000 | — |
| Louisiana | $15,000 | $30,000 | $25,000 | — |
| Pennsylvania | $15,000 | $30,000 | $5,000 | — |
| Florida | No BI required — uses PIP system (10K PD minimum) | — | ||

Notice something striking: between 2025 and 2026, six states raised their minimums — California for the first time since 1967. That's not a coincidence. It's a signal that 59-year-old coverage limits are dangerously outdated given today's medical costs and vehicle prices.
The Liability Gap: What a Real Accident Actually Costs
Here's where most liability conversations go wrong. People focus on whether they meet the legal minimum without asking whether the minimum is actually enough to protect them. The answer, in most cases, is no.
According to the Insurance Information Institute's 2024 data, the average bodily injury liability claim is $28,278. The average property damage claim is $6,770. With the most common state minimum of 25/50/25, your per-person bodily injury limit is $25,000 — $3,278 less than the average claim. That difference is money you owe out of pocket.
Imagine you cause an accident that injures one person. The average bodily injury claim is $28,278. Your 25/50/25 policy pays $25,000. You personally owe the remaining $3,278 — and that's for an average accident, not a serious one.
Now consider a more realistic serious crash — one with multiple injuries:
| Scenario | Total Claim Cost | 25/50/25 Covers | Your Exposure | 100/300/100 Covers |
|---|---|---|---|---|
| 1 person injured (average) | $28,278 | $25,000 | $3,278 | $28,278 ✓ |
| 2 people injured | $56,556 | $50,000 | $6,556 | $56,556 ✓ |
| 3 people injured | $84,834 | $50,000 | $34,834 | $84,834 ✓ |
| Serious injury (1 person) | $250,000+ | $25,000 | $225,000+ | $150,000+ remaining |
Based on Insurance Information Institute average claim costs (2024) and ConsumerShield settlement data (April 2026). Serious injury assumes surgical intervention or extended rehabilitation.
When your insurance runs out, the injured party's attorney can come after your savings, your home equity, your future wages. That's not hypothetical — it happens routinely in serious accidents.
How Much Liability Coverage Do You Actually Need?
The Insurance Information Institute and most financial advisors recommend 100/300/100 as a baseline for anyone with meaningful assets. Here's a practical framework:
Add up your exposed assets
Include savings, investment accounts, home equity, and 5 years of income. If you have $200,000 in assets, you need at least $200,000 in liability coverage — meaning 100/300/100 at minimum.
Match coverage to your net worth
If your assets are under $100,000, 50/100/50 may be adequate. Over $300,000? Consider an umbrella policy that stacks on top of your auto policy for another $1 million in coverage.
Consider your driving exposure
If you drive frequently, commute long distances, or drive in heavy urban traffic, your risk of an at-fault accident is meaningfully higher. Higher limits cost relatively little more.
Don't set it and forget it
Revisit your limits whenever your net worth changes significantly — after a home purchase, inheritance, or major salary increase.
What Different Liability Levels Actually Cost
The coverage gap between minimum limits and recommended limits is enormous. The cost gap is surprisingly small:
| Coverage Level | Monthly Premium (avg) | Annual Premium (avg) | Upgrade Cost vs. Minimum |
|---|---|---|---|
| 25/50/25 (Common minimum) | $68 | $816 | — |
| 50/100/50 | $73 | $876 | +$5/month |
| 100/300/100 Recommended | $82 | $984 | +$14/month |
Source: National average rate estimates from MoneyGeek and carrier data (2026). Rates based on 35-year-old driver with clean record in a mid-size sedan. Actual premiums vary by state, insurer, and driver profile.
Fourteen dollars per month. That's the cost to go from $25,000 of bodily injury coverage per person to $100,000 — four times the protection for less than a daily cup of coffee. Framed differently: upgrading to 100/300/100 costs about $168/year but closes your liability gap on the average accident entirely.
If you have significant assets (home equity, savings, investments), consider adding a personal umbrella policy on top of your auto coverage. A $1 million umbrella typically costs $150–$300/year and kicks in after your auto liability limits are exhausted. For high-net-worth drivers, this is one of the smartest coverage decisions you can make.
What Liability Insurance Does NOT Cover
Understanding the limits of liability coverage is just as important as understanding what it does cover. Liability never pays for:
- Your own medical bills — you'll need health insurance, PIP, or MedPay for those
- Damage to your own vehicle — that's what collision coverage is for
- Your passengers' injuries if you're at fault — covered by their health insurance or your MedPay
- Accidents where you're not at fault — the other driver's liability pays (or uninsured motorist coverage if they're uninsured)
- Intentional acts — insurers won't cover damages from deliberate misconduct

Frequently Asked Questions
Liability car insurance covers injuries and property damage you cause to other people in an at-fault accident. It's split into bodily injury liability (medical bills, lost wages, and legal costs for injured parties) and property damage liability (repair or replacement of vehicles and property you damage). It does not cover your own injuries or vehicle damage.
The Insurance Information Institute recommends at least 100/300/100 ($100,000 per person, $300,000 per accident, $100,000 property damage) for most drivers. A practical rule: your total liability limits should equal or exceed your net worth. If you have significant assets, consider adding a personal umbrella policy for an additional $1 million in coverage.
Liability-only insurance meets legal requirements but is rarely enough financial protection. The average bodily injury claim is $28,278, according to the Insurance Information Institute — which already exceeds the $25,000 per-person minimum in most states. In a multi-person accident, the gap grows dramatically. Drivers with any significant assets should carry at least 100/300/100 limits.
Once your liability limits are exhausted, you're personally responsible for the remaining balance. The injured party can sue you and a court can order wage garnishment, property liens, or seizure of assets to satisfy the judgment. This is why carrying limits well above state minimums is essential for anyone with savings, home equity, or a future income to protect.
