Full Coverage vs Liability-Only: How to Choose

Should you get full coverage or just liability?

If you owe money on your car, you do not get to choose. Your lender will require full coverage until the loan is paid off. If you own the car outright, the choice is yours. It comes down to one question: could you replace this car from savings if it were totaled tomorrow?

If you could, and the car is older and worth little, liability-only can be a sensible way to save. If you could not, full coverage is usually worth its price, even on an older car. Guess wrong and you either overpay every year or face a bill you cannot cover.

Either way, do not cut liability to the bone. That is the part that protects your savings if you hurt someone, and the legal minimum is thin there (more on that below).

This guide takes the decision in order. First what the words mean, then what your lender can force, then a quick test of whether your car is worth covering, then what it all costs.

What does “full coverage” actually mean?

It is not an official policy type. Shoppers, lenders and sales sites use it for three coverages bought together:

• Liability pays for injuries and damage you cause to other people and their property. It never pays to fix your own car.
• Collision pays to repair or replace your car after a crash, whoever is at fault.
• Comprehensive pays for damage that is not a crash: theft, fire, hail, flood, vandalism, hitting an animal.

Two policies sold as “full coverage” can still differ. One may include rental car money or roadside help, and the other may not. So ask for an itemized quote showing each coverage, its limit and its deductible. A deductible is the amount you pay yourself before the insurer pays.

A liability-only policy is a complete, legal policy. It just leaves your own car unprotected. And “full coverage” with minimum liability limits protects other people no better than liability-only does. What it adds is protection for your car.

Full coverage also does not cover everything:

• Collision will not pay for a mechanical breakdown or normal wear.
• After a total loss, the insurer pays what a similar used car is worth, minus your deductible. It does not pay the price of a new car.
• Rental cars, roadside help, custom parts and belongings in the car are usually add-ons.
• If you owe more than the car is worth, the leftover is a separate problem. See our guide to GAP insurance.

Does my lender make me keep full coverage?

Yes, while you owe money or lease the car. That rule comes from your loan or lease contract, not from state law. In the states we checked, no law requires collision or comprehensive. Lenders ask for it because the car is their security. Read your agreement for the exact terms. It may also set a minimum for your liability limits.

Dropping the coverage anyway tends to backfire. If your coverage lapses, the lender can buy a policy for itself and add the cost to your loan payment. That policy protects only the lender, not you. Washington’s insurance commissioner says these policies usually cost much more than your own.

If your lender says it cannot find your coverage, send it the summary page of your policy. That page should list the lender as the lienholder, meaning the company with a claim on the car.

Once the loan is paid off, the requirement ends.

When can you drop full coverage? The 10% test

No regulator sets a rule here. The common rule of thumb, from MoneyGeek and Insure.com, is this: if a year of collision and comprehensive costs 10% or more of what your car is worth, take a hard look at dropping them. Treat it as a prompt to review, not a verdict.

The reason is simple. The most insurance can ever pay is your car’s current value minus your deductible. As the car ages, that ceiling falls, but the price often does not.

Example (invented numbers). Your car is worth $4,000. Collision and comprehensive cost $800 a year, and your deductible is $1,000. For scale, $800 is about what the two cost on average across the country, but your quote will differ.

• A year of coverage costs 20% of the car’s value.
• The most you could ever collect is $3,000, which is $4,000 minus $1,000.
• After about four years of premiums, you will have paid more than that.

This car fails the test. If you could replace it from savings, dropping the coverage makes sense and keeps $800 a year in your pocket.

Now say the car is worth $16,000. The same $800 is 5% of its value, and a total loss would pay up to $15,000. Keep the coverage.

The test is only half the answer. Insurance is not meant to pay itself back. The real question is whether a total loss would leave you in debt or without a way to get to work. MoneyGeek reaches the same place in its own example: keep the coverage unless you hold the maximum payout in savings.

A few ways to make the test more accurate:

• Use real numbers. Look up your car’s current value at each renewal, and use your own quote.
• Test each coverage on its own if your insurer sells them separately. Comprehensive costs a little over half as much as collision on average, so it stays worth keeping longer.
• Know what drives the price. Luxury, sports and costly-to-repair cars cost the most to cover. An older economy car may sit well below $800.

Is the state minimum enough liability?

Probably not for a serious crash. The minimum is the least the law lets you carry, not what a crash tends to cost.

Here is the scale. Triple-I reports that the average paid injury claim in 2024 was $28,278. That is above the $25,000 per-person minimum in Connecticut, Alabama and Delaware, and close to Texas’s $30,000. It is a national average, not a forecast for your state. The real danger is the claims far above average.

Anything over your limit is your bill. The injured person can sue you for the rest.

Property damage works the same way. The average new vehicle sold for about $50,089 in August 2026, according to Kelley Blue Book. A $10,000 limit, the minimum in Delaware and Florida, covers about a fifth of that. The average property claim is only $6,770, but a newer pickup or a crash with several cars can blow past a low limit.

Other drivers are a risk too. About 15 in 100 U.S. drivers were uninsured in 2023, and about one in three was uninsured or underinsured, according to the Insurance Research Council. If one of them hits you and you carry liability only, whether your car gets repaired depends on one add-on. It is uninsured-motorist coverage for property damage, and it varies by state. See our uninsured motorist guide.

Collision helps in another way. It lets you get your car fixed through your own insurer when the other driver’s insurer will not pay.

Our state minimums guide lists every floor, and the liability limit checker helps you compare your own.

How much more does full coverage cost?

It depends on what you compare. Published “full coverage” prices bundle two changes at once: higher liability limits and car-damage coverage. Here is what three sources found:

• NerdWallet (October 2026) puts full coverage at $2,361 a year against $648 for state-required coverage only. That is 3.6 times as much. But its “full” profile also raises liability to 100/300/50, meaning $100,000 per injured person, $300,000 per crash and $50,000 for property damage.
• MoneyGeek (August 2026) shows collision and comprehensive adding only $141 a year at minimum limits ($747 to $888). Moving up to 100/300/100 limits added about $709 more.
• NAIC’s 2024 averages across every insured car are about $516 a year for collision and $283 for comprehensive. Together that is close to $800.

So the car-damage part alone has been published at anywhere from $141 to about $800 a year. Some of that gap is who is being priced. MoneyGeek’s driver has a clean record and good credit, while NAIC averages everyone. MoneyGeek’s own text also says $67 to $86 a month, which does not match its table. The sources disagree, so get your own quote.

Where you live matters too. NAIC’s average collision price runs from $339 in Iowa to $718 in California. These are published estimates, not quotes. For more on what shapes a price, see how to read a car insurance quote and how much car insurance costs. We also have pages for Texas and Florida.

What are the in-between options?

You do not have to pick an end.

• Keep comprehensive, drop collision, where your insurer allows it. You keep theft, hail and flood protection at the lower price.
• Raise your deductible. MoneyGeek lists $250, $500 and $1,000 as typical. A higher deductible lowers the premium but raises what you pay on every claim. Only do it if you could pay that amount in cash.
• Raise liability and skip car-damage coverage. With an old car and real savings to protect, higher liability can matter more than collision.
• Keep the personal-protection coverages. Personal injury protection or medical payments pay your own and your passengers’ medical bills. Uninsured/underinsured coverage pays when the other driver has too little insurance. The car-value test does not apply to them.
• Shop the pieces. Ask each insurer to price liability, collision and comprehensive separately. Our guide to lowering your car insurance covers other ways to cut the bill.

What to do next

1. Check whether you owe on the car or lease it. If yes, keep collision and comprehensive, and read the contract to see what it requires. You can stop here.
2. Pick your liability limits first. Ask for quotes at the state minimum and at higher limits, so you can see what each step up costs. Weigh that against what you could lose in a lawsuit: your savings and your paycheck. For scale, the average injury claim was $28,278.
3. Look up your car’s current value in a pricing guide such as Kelley Blue Book. Subtract your deductible. That is the most you would collect.
4. Get an itemized quote for collision and comprehensive, priced separately if the insurer allows it.
5. Divide each yearly price by the car’s value. At 10% or more, look closer.
6. Ask yourself: could I replace this car within a month without borrowing? If not, keep the coverage even above 10%.
7. Repeat at each renewal and when the loan ends. Your car loses value every year, so the answer changes.

Common mistakes

• Dropping coverage on a financed car. The lender’s replacement policy can cost more than yours and protects only the lender.
• Going by the percentage alone. A car can fail the 10% test and still be one you cannot afford to lose.
• Assuming “full coverage” means high limits. It can come with the state minimum.
• Expecting a new-car check after a total loss. You get the used value, minus your deductible.

The numbers in one place

Liability limits are written as three figures: injury per person, injury per crash, and property damage, each in thousands of dollars. So 30/60/25 means $30,000, $60,000 and $25,000.

NAIC also warns that state-to-state comparisons need great care. These figures are published estimates for the profiles shown, not quotes.

Bottom line

If you owe on the car, keep full coverage. If you own it and a year of collision and comprehensive costs 10% or more of its value, and you could replace it from savings, liability-only is reasonable. If you could not replace it, keep full coverage and raise your deductible to lower the price. Whatever you choose, set your liability limits first.
