How Much Car Insurance Do I Need? Liability Limits Explained
Quick summary: State minimum car insurance keeps you legal but rarely protects your savings. Most drivers with assets should carry at least 100/300/100 liability with matching uninsured motorist coverage; full coverage averaged about $2,357 a year in 2026 versus $650 for minimum coverage.
Buying only your state’s minimum car insurance is the cheapest option today and potentially the most expensive mistake tomorrow. This guide explains each coverage on your policy, what the numbers like 100/300/100 mean, how much coverage most drivers should carry and how much it costs.
Understanding liability limits (the three numbers)
Liability coverage pays for injuries and damage you cause to others. Limits are written as three numbers in thousands of dollars:
| Number | Meaning | Example: 100/300/100 |
|---|---|---|
| First | Bodily injury per person | Up to $100,000 for each injured person |
| Second | Bodily injury per accident | Up to $300,000 total for all injured people |
| Third | Property damage per accident | Up to $100,000 for cars, buildings and property you damage |
If damages exceed your limits, you can be personally sued for the difference, putting your savings, home equity and future wages at risk.
Every coverage on a car insurance policy
| Coverage | What it pays for | Required? |
|---|---|---|
| Bodily injury liability | Other people’s medical bills, lost wages, legal costs | Required in almost every state |
| Property damage liability | Other people’s cars and property | Required in almost every state |
| Uninsured/underinsured motorist (UM/UIM) | Your injuries when the at-fault driver has no or too little insurance | Required in some states |
| Personal injury protection (PIP) / medical payments | Your and your passengers’ medical bills regardless of fault | Required in no-fault states (e.g., Florida, New York, Michigan) |
| Collision | Damage to your car from a crash, minus deductible | Required by lenders on financed or leased cars |
| Comprehensive | Theft, hail, flood, fire, vandalism, animal strikes | Required by lenders on financed or leased cars |
| Rental reimbursement, roadside, gap | Optional extras | Optional (gap often required on some leases) |
State minimums are low
Every state sets minimum liability limits, and many are far below what a serious accident costs. A few examples:
| State | Minimum liability | Notes |
|---|---|---|
| California | 30/60/15 | Raised from 15/30/5 in 2025 |
| Texas | 30/60/25 | — |
| North Carolina | 50/100/50 | Raised in July 2025; UM/UIM also required |
| New York | 25/50/10 | Plus $50,000 PIP and uninsured motorist coverage |
| Florida | No bodily injury minimum | Requires $10,000 PIP and $10,000 property damage |
A single hospital stay after a crash can exceed $30,000, and a new SUV can cost more than $50,000 to replace — more than many minimum property damage limits.
How much car insurance should you carry?
| Your situation | Suggested liability | Other coverage |
|---|---|---|
| Few assets, older car | At least 50/100/50 | UM/UIM matching your liability; consider dropping collision on a low-value car |
| Homeowner or moderate savings | 100/300/100 | UM/UIM 100/300; collision and comprehensive if the car is worth more than ~10x the premium |
| Significant assets or high income | 250/500/100 or higher | Add a $1 million+ umbrella policy |
| Financed or leased car | Whatever you choose above | Collision + comprehensive required; consider gap insurance |
A simple rule of thumb
Carry liability limits at least equal to your net worth (what you own minus what you owe), and add an umbrella policy if your assets exceed your auto limits. See what umbrella insurance is and who needs it.
How much does it cost?
A late-2026 national analysis put average costs at about $2,357 per year (~$196/month) for full coverage and $650 per year (~$54/month) for state-minimum coverage, for a 35-year-old driver with a clean record and good credit.
| Driver profile (full coverage) | Approximate average per year |
|---|---|
| Clean record, good credit | $2,357 |
| One speeding ticket | $3,022 |
| One at-fault accident | $3,514 |
| Poor credit | $3,939 |
| DUI | $4,424 |
Going from minimum limits to 100/300/100 liability usually costs much less than the gap between “minimum” and “full coverage,” because most of the full-coverage price is collision and comprehensive.
Choosing your deductibles
- Collision and comprehensive have deductibles (often $500 or $1,000).
- A higher deductible lowers your premium, but choose an amount you could pay tomorrow without stress.
- Some states offer $0 glass deductibles for windshield repairs.
Step-by-step: build your policy
- Check your state minimums and whether you live in a no-fault state.
- Estimate your net worth to choose liability limits.
- Match UM/UIM to your liability limits.
- Decide on collision and comprehensive based on your car’s value.
- Pick deductibles you can afford.
- Get at least three quotes with identical limits — see how to compare insurance quotes.
Bottom line: state minimums keep you legal, not protected. Most drivers with any savings should carry at least 100/300/100 with matching uninsured motorist coverage, and add an umbrella policy when assets grow. Want to cut the cost? Read 10 ways to lower your car insurance premium.
