How Much Car Insurance Do You Actually Need? State-by-State Guide

Why State Minimums Are Dangerously Low

Every state (except New Hampshire) requires some minimum auto insurance. But these minimums were often set decades ago and haven't kept pace with rising medical costs, car values, or lawsuit awards.

Consider this reality check:

•The average ER visit costs **$2,200–$3,500**

•A broken leg can cost **$7,500–$35,000** in medical bills

•The average new vehicle price in 2026 is **$48,500**

•The median personal injury auto lawsuit settlement is **$52,900**

Now compare that to typical state minimums of $25,000–$30,000 in bodily injury per person. One serious accident could exceed your coverage by tens of thousands of dollars — and you're personally liable for the difference.

Coverage Types Explained

Liability Insurance (Required)

Pays for damage YOU cause to others. Expressed as three numbers (e.g., 100/300/100):

•First number: Bodily injury per person ($100K)

•Second number: Bodily injury per accident ($300K)

•Third number: Property damage per accident ($100K)

Collision

Pays to repair or replace YOUR car after an accident, regardless of fault. Subject to a deductible ($250–$2,000). Required by lenders if you have a loan or lease.

Comprehensive

Pays for non-collision damage to YOUR car: theft, vandalism, hail, flooding, animal strikes, falling objects. Also subject to a deductible.

Uninsured/Underinsured Motorist (UM/UIM)

Covers your medical bills and damages when the at-fault driver has no insurance or insufficient coverage. One of the most important coverages you can buy.

Medical Payments / PIP

Covers medical expenses for you and your passengers regardless of fault. PIP (Personal Injury Protection) is broader and required in no-fault states.

How Much Coverage Do You Need? The Asset-Based Approach

Rule of thumb: Your liability limits should equal or exceed your net worth.

Your Situation	Recommended Liability	Collision/Comp	UM/UIM
Few assets, older car	State minimum or 50/100/50	Consider dropping	Match liability
Some assets ($50K–$200K)	100/300/100	$500 deductible	100/300
Significant assets ($200K+)	250/500/250	$500 deductible	250/500
High net worth ($500K+)	250/500/250 + umbrella policy	$1,000 deductible	250/500

When to Drop Collision and Comprehensive

Use the 10:1 rule: If your car's current market value is less than 10 times the annual cost of collision + comprehensive, consider dropping those coverages.

Example:

•Your car's value: $5,000

•Annual collision + comprehensive cost: $600

•Ratio: 5,000 ÷ 600 = 8.3 (below 10 — consider dropping)

But first, ask yourself:

•Could you afford to replace this car out of pocket if it were totaled?

•Is the car your only transportation?

•Do you have an emergency fund that could cover a replacement?

If you answered "no" to any of these, keep the coverage even if the math suggests dropping it.

Full Coverage vs. Liability Only: Cost Comparison

State	Liability Only (Annual)	Full Coverage (Annual)	Difference
Michigan	$1,020	$2,700	+$1,680
Florida	$810	$2,200	+$1,390
Texas	$680	$1,842	+$1,162
California	$650	$1,780	+$1,130
Ohio	$390	$1,050	+$660
Maine	$380	$1,020	+$640
National Avg	$650	$1,750	+$1,100

5 Situations Where You Need More Than Minimum Coverage

1**You own a home** — A lawsuit judgment can put a lien on your house if your insurance doesn't cover the full damages

2**You have savings or investments** — Assets above state exemptions are at risk in a liability lawsuit

3**You commute in heavy traffic** — Higher accident frequency = higher risk of a major claim

4**You drive with passengers often** — More people in the car = more potential injury claims

5**You have a teen driver on your policy** — Teens are statistically the highest-risk drivers on the road

The Bottom Line

•**Never carry just state minimums** if you have any assets to protect

•**100/300/100 is the minimum** most insurance professionals recommend

•**Match your UM/UIM to your liability limits** — don't skip this coverage

•**Keep collision/comprehensive** on cars worth more than $5,000–$8,000

•**Consider an umbrella policy** if your net worth exceeds $300,000

•**Re-evaluate annually** as your car depreciates and your financial situation changes

Frequently Asked Questions

Is minimum car insurance enough?

In most cases, no. State minimums are dangerously low. For example, Texas's minimum property damage coverage is $25,000 — but the average new car costs $48,000. If you cause an accident totaling a new SUV, you'd be personally liable for $23,000+. Experts recommend at least 100/300/100 for anyone with assets to protect.

Do I need full coverage on an older car?

Not necessarily. The general rule: if your car's value is less than 10 times the annual cost of collision + comprehensive coverage, consider dropping those coverages. For example, if collision + comprehensive costs $600/year and your car is worth $4,000, the math is borderline. Below $3,000 in value, most experts say skip it.

What does full coverage actually mean?

There's no official definition. In practice, 'full coverage' means liability (100/300/100 recommended), collision ($500 deductible), comprehensive ($500 deductible), uninsured/underinsured motorist, and medical payments or PIP. Your lender defines minimum 'full coverage' requirements if you're financing.

Should I get uninsured motorist coverage?

Absolutely yes, especially in states with high uninsured driver rates. Nationally, about 14% of drivers are uninsured — in some states it exceeds 20% (Mississippi 22.3%, Michigan 25.5%). UM/UIM coverage protects you when the at-fault driver has no insurance or insufficient coverage.

How much does full coverage cost vs. liability only?

Full coverage costs roughly 2-3x more than liability-only. National averages: liability only costs ~$650/year vs. full coverage at ~$1,750/year. The exact multiplier depends on your car's value, age, and state.
