- Liability insurance covers the damage you cause others; full coverage adds protection for your vehicle, too.
- The cost difference between liability-only and full coverage is $1,476 per year on average, according to our 2026 analysis of data from Quadrant Information Services.
- Nearly all states require some level of liability coverage; most lenders will also include mandatory full coverage if you’re leasing or financing your car.
- Full coverage usually makes financial sense when it would cost more to replace your car than you could afford to pay out of pocket.
Liability car insurance covers damage you cause to other people, whether it’s bodily injury or property damage. Full coverage also includes collision and comprehensive coverage, both of which protect your own vehicle. At standard 100/300/100 limits, full coverage car insurance costs an average of $1,476 more per year than liability-only, according to 2026 data from Quadrant Information Services.
“Full coverage” isn’t a separate product you buy, but rather a description of having all three coverages: liability, collision and comprehensive. Learn more about the differences between liability-only vs. full coverage car insurance in our guide below.
Sophie’s Tip
Take your comparison results with you when comparing quotes. Asking insurers to match your situation — not theirs — is how you stop overpaying for coverage that doesn’t fit.
Liability vs. full coverage: The core difference
Liability covers damage you cause to others; full coverage adds collision and comprehensive coverage that protects your own vehicle. Most states require liability; lenders typically require full coverage.
| Features | Liability | Full coverage |
|---|---|---|
| Who or what it protects | Injuries you cause others; damage you do to others’ property | Injuries and property damage to others, plus damage to your own car |
| Typical cost | Lower | Higher |
| When it’s required | Required in almost every state | Typically required when leasing or financing a vehicle |
Full coverage car insurance comprises liability, comprehensive and collision coverage. Another way to look at it: Liability is what you owe other people when you cause an accident; full coverage is what you owe yourself.
Just because it’s called “full” coverage doesn’t mean everything is covered, however. Adding collision and comprehensive offers financial protection if your car is damaged. It doesn’t cover your own medical bills after a breakdown, for example. It also won’t cover typical wear and tear on your vehicle or repairs after a breakdown.
What liability car insurance covers
Liability car insurance coverage includes bodily injury and property damage, up to the limits of your policy. The bodily injury portion of liability insurance covers injuries you (or someone driving your vehicle) cause while driving. Property damage is damage done to someone else’s vehicle or property.
For example, say you’re driving, and you accidentally hit someone else’s vehicle with your car. They got a broken arm and a dented door panel in the accident. Your liability car insurance could help pay for their medical treatment (doctor visit, cast) and repairs to their car (new door panel, paint touch-up). Liability insurance could also help with legal costs if the other driver sues you over the accident.
Every state but New Hampshire requires some level of liability car insurance. State minimum liability requirements vary by state, but they’re often too low to cover all of your expenses after an accident. Carinsurance.com recommends standard coverage levels of 100/300/100 for better financial protection.
Liability covers damage and injuries you cause others, but it doesn’t cover your own vehicle if it’s damaged. For that, you’ll need full coverage: collision and comprehensive insurance.
What full coverage car insurance covers
Full coverage car insurance includes liability, collision and comprehensive insurance. Collision insurance covers your own car, regardless of fault, and helps pay for repairs or replacement of your vehicle after it’s damaged in an accident. For example, if another driver hits your vehicle, collision coverage could pay to repair the damage. Comprehensive insurance covers other types of vehicle damage, such as hail, animal, fire, theft, or vandalism. For instance, if a thief steals your car, comprehensive coverage could help you replace it.
Full coverage means you have the full package of insurance coverages. But what’s included in this complete package varies by insurer. Some quotes bundle uninsured/underinsured motorist (UM/UIM) and personal injury protection (PIP) under the same label; others don’t.
Full coverage is usually a requirement when you finance a vehicle through a lender, since the car is used as collateral.

Liability-only car insurance: Pros and cons
Liability-only car insurance is the cheapest legal option, but it leaves your own car uninsured.
According to 2026 rate data, liability-only car insurance costs an average of $829 per year at 50/100/50 limits, or $1,102 per year at 100/300/100 limits. State minimum liability-only coverage costs $738 annually.
Pros
- Lower cost than full coverage
- Simple policy without any extras
- Makes sense for low-value cars
- Satisfies your state’s legal requirements
Cons
- Doesn’t protect your car against collision damage or other types of damage
- Most lenders won’t accept liability-only coverage on financed cars
- You’re responsible for paying all other costs out of pocket
- Lower coverage limits (which are often the default) increase your exposure to out-of-pocket costs
Full coverage car insurance: Pros and cons
Full coverage protects you financially after a crash, regardless of who is at fault, but it’s the comprehensive and collision coverages that drive the cost. Full coverage at standard limits (100/300/100) with a $500 deductible costs an average of $2,578/year nationally, according to 2026 rate data.
Pros
- Protects your vehicle financially from the costs of a collision or other covered damage
- Satisfies lender requirements
- Offers peace of mind on newer cars
- Often bundled with higher liability limits, giving you additional protection
Cons
- Typically has higher premiums
- Cost can outpace your car’s value as the car ages and depreciates
- The deductible applies to comprehensive and collision claims
- It doesn’t cover everything (such as medical bills or breakdowns)
Full coverage runs about $1,476 more per year than liability-only at the same limits — and almost all of that extra cost goes to insuring your own car, not someone else’s.
Liability vs. full coverage: 2026 cost comparison
Adding comprehensive and collision insurance to your liability policy at standard 100/300/100 limits costs about $1,476 per year on average.
Sophie’s Tip
That $1,476 a year covers damage to your car from theft, weather and animals. The right question to ask yourself is “What does $1,476 buy me for my car?” not “How do I avoid this expense?” If your car’s worth less than a few thousand dollars, the answer might be “not much.” But if it’s worth $15,000 or more, full coverage is usually a bargain.
Cost of adding comprehensive and collision by state
The table below shows the cost of liability-only insurance with 100/300/100 limits in each state, as well as the cost of full coverage (including comprehensive and collision). See how the cost to move to full coverage is 2.5 times higher in Michigan ($2,378/year) than in Maryland ($955/year), even at the same liability limits.

Liability-only vs. full coverage cost by company
The insurer matters when comparing cost, too. Travelers offers the cheapest widely available full coverage at $1,962/year on average; Farmers and Allstate run roughly 50% higher.
See the average cost of liability and full-coverage car insurance by the insurer in the table below.
| Company | Liability 100/300/100 | Full coverage 100/300/100 |
|---|---|---|
| Travelers | $1,008 | $1,962 |
| GEICO | $932 | $2,159 |
| Nationwide | $1,113 | $2,524 |
| Progressive | $1,227 | $2,569 |
| State Farm | $1,422 | $2,875 |
| Allstate | $1,409 | $3,159 |
| Farmers | $1,610 | $3,207 |
| USAA* | $628 | $1,628 |
Note: USAA eligibility is restricted to military and qualifying family members
Liability-only vs. full coverage cost by age
Your driver profile and demographics also affect the price. Note that teens pay roughly three times as much for insurance, regardless of whether it’s liability or full coverage. Coverage choice can’t fix age-driven pricing. In the table below, see how much liability-only insurance costs vs. full coverage for teens, young adults, adults and seniors.
| Age band | Liability 100/300/100 | Full coverage 100/300/100 |
|---|---|---|
| Teens (16–19) | $3,541 | $8,045 |
| Young adults (20–24) | $1,663 | $4,051 |
| Adults (25–60) | $1,103 | $2,575 |
| Seniors (65–75) | $1,154 | $2,531 |
When liability-only is worth it (and when it’s not)
Liability-only car insurance is the right fit for some drivers — and the wrong call for others. Here’s how to tell which.
Worth it
- You can afford to repair or replace your car out of pocket if something happens to it. You don’t need to pay for comprehensive or collision coverage if you can replace the car using your savings. A common rule of thumb is that when the car’s value is below $5,000.
- You own your car free and clear. You don’t need to follow a lender’s requirements if you don’t have a car loan.
- You’re a low-mileage driver. If you don’t drive much and being without a car isn’t a hardship, it’s less likely something will happen to it — and if it does, you have alternative transportation options.
Not worth it
- You’d be stranded if your car were totaled. If damage to your vehicle would leave you with no way to get to work or other everyday activities, keeping liability-only coverage could leave you vulnerable.
- You’re an inexperienced driver. Teens and people with little driving experience are statistically more likely to be in an accident. Liability-only insurance would leave you exposed to hefty out-of-pocket costs for repairs.
Still not sure? Here’s how to decide if you still need full coverage.
Sophie’s Tip
If you saw your own situation on the “worth it” list, liability-only is doing its job. If you saw it in the “not worth it” list, full coverage is the safer call. If you’re in between, keep full coverage one more year and revisit when your car’s value drops below $5,000.
When full coverage is worth it (and when it’s not)
Full coverage makes sense for many drivers, but not everyone needs it. Consider whether your situation makes it worth it or not:
Worth it
- You drive a new car. New-car values average around $50,000, which is more than many people can afford to pay out of pocket after an accident.
- You’re financing your car with an auto loan. Your lender will require you to carry full coverage to protect their collateral — no getting around it.
- You live in an area with a high risk of damage. If your region experiences frequent severe weather (hail, tornadoes, hurricanes) or high rates of theft or accidents, your vehicle is more likely to need repairs.
Not worth it
- You drive an old, paid-off car with low actual cash value. The cost of repairs + your deductible could be more than the price to replace the car.
- You have a strong savings cushion and a secondary vehicle. You could afford to pay for repairs and drive your backup vehicle while the damaged one is in the shop.
Also consider whether your premiums would exceed 10% of the car’s value. This is a common rule of thumb for weighing the price of protection against the value of what you’re protecting. If you’re paying too much for coverage, it’s worth finding an alternative.
Add-on coverages worth considering with either policy
Most policies, whether liability-only or full coverage, let you add other coverages that protect you, your passengers and your finances.
Uninsured motorist (UM) / underinsured motorist (UIM)
Uninsured motorist coverage helps cover your costs when you’re in an accident with a driver with too little coverage or no coverage at all. Since about 15% of drivers on the roads in the U.S. carry no insurance, according to the Insurance Information Institute, UM/UIM coverage can help protect you from the costs caused by these drivers. Learn more about uninsured motorist statistics by state.
Personal injury protection (PIP) / medical payments (MedPay)
MedPay can help cover medical expenses after an accident, regardless of who was at fault. Personal injury protection can cover medical expenses, but also could cover other types of expenses you may have after an accident, such as child care or lost wages.
GAP insurance
If you’re in an accident and your vehicle is totaled, the insurance payout you receive might not be enough to pay off your car loan. Guaranteed Asset Protection helps cover the gap between your vehicle’s value and the balance remaining on your auto loan. Therefore, GAP is only necessary if you’re driving a financed vehicle or leasing.
What changes when you switch from full coverage to liability
The general rule of thumb is to switch when your full-coverage premium climbs above roughly 10% of your car’s actual cash value.
When switching, your premium will likely drop sharply. It’s a 57% drop, on average, when moving from full coverage to liability-only at 100/300/100 limits. In exchange for lower premiums, you assume all the risk for your vehicle. If you’re in an accident and your car is damaged, the responsibility for paying for repairs (or replacing the vehicle) is entirely on you.
However, in some states, it’s not that simple. For example, in no-fault states like Michigan, personal injury protection is still required, unless you can prove a qualifying health insurance policy that covers accidents.
One word of caution: don’t drop collision and comprehensive on a financed car, even if you’re close to paying it off. The lender still owns a stake in that vehicle and is likely to have included a full coverage requirement in your loan contract.
Common mistakes when comparing liability and full coverage
Making one of these mistakes could have costly consequences.
- Assuming “full coverage” means everything is covered. You might be surprised when you go to file a claim. Mechanical breakdowns, custom equipment and damage sustained while using the vehicle for ridesharing without a Hired and Non-Owned Auto (HNOA) policy will all need to be covered out of pocket.
- Carrying state-minimum liability when you can afford to go higher. Raising your liability limits is the cheapest upgrade you can make and they could have a serious benefit if you’re in an accident. On average, it costs about $364 more per year to move from state minimums to 100/300/100 limits.
- Keeping full coverage on a car worth less than what the policy costs for over 2 years. You will have paid out more in premiums than what the policy could pay you after an accident.
- Dropping full coverage while still financing the car. That could break your loan contract, which most likely requires full coverage insurance for the duration of the loan. Your insurer could force-place insurance on the vehicle and charge you for the policy.
- Not comparing apples to apples when shopping for quotes. Comparing one carrier’s “full coverage” quote to another’s “full coverage” quote without checking what’s actually in each bundle means you might actually be overpaying for what you get. Read your quotes carefully to see what’s included so you can make accurate comparisons.
The cheapest coverage upgrade isn’t full coverage — it’s higher liability limits. Raising only your liability limits from 50/100/50 to 100/300/100 averages $273 more per year nationally.
Frequently Asked Questions
Does liability cover my car if I’m in an accident?
No. Liability insurance only covers what you owe to other people for injuries or property damage you’ve caused. If you want your car financially protected, you’ll need full coverage.
Is full coverage required by law?
No. Most states require some level of liability coverage to protect other people from injury or damage you cause while driving. Protecting your own vehicle from damage is not a state requirement. However, you might be bound by a contract to buy full coverage insurance if you’re leasing or financing a vehicle.
How much more does full coverage cost than liability?
It costs an average of $1,476 more per year to move from liability-only to full coverage car insurance. That works out to an additional $123 per month for added protection for your vehicle.
When should I drop full coverage and switch to liability?
Your vehicle may depreciate to a point where it no longer makes financial sense to maintain full coverage. Consider dropping collision and comprehensive when your full coverage premiums cost 10% or more of the car’s actual cash value.
Does “full coverage” mean everything is covered?
No. Full coverage is insurance shorthand for an auto policy that contains liability, collision and comprehensive insurance. Full coverage insurance doesn’t cover mechanical breakdowns, everyday wear and tear, custom equipment or medical bills.
Will my lender let me drop full coverage if I’m close to paying off?
No. You’ll generally need to maintain full coverage up until the vehicle is fully paid off and you’ve transferred the title to your name.
Can I have full coverage on one car and liability on another?
Yes. It’s perfectly fine to tailor your coverage to the specifics of the vehicle. For example, if you drive a new car worth $50,000, it probably makes sense to keep full coverage on it. But if your backup car is 15 years old and worth just $3,500, you can probably consider liability-only coverage.
Does full coverage cover other drivers using my car?
Yes, your coverage will typically follow the car when you allow someone else to drive it. If you have other drivers in your household, it’s typically required to include them in your policy as named drivers.
Key terms
- Bodily injury liability (BI): Pays for injuries you cause to other people in an accident, including medical bills, lost wages and legal costs if you’re sued.
- Property damage liability (PD): Pays for damage you cause to someone else’s vehicle or property, such as a guardrail, fence, or storefront.
- Collision coverage: Pays to repair or replace your own vehicle after a collision with another car or object, regardless of who caused the accident.
- Comprehensive coverage: Pays for damage to your vehicle from non-collision events, including theft, vandalism, hail, fire and animal strikes.
- Deductible: The amount you pay out of pocket on a claim before your insurance kicks in to cover the rest. A $500 deductible means you pay the first $500; your insurer covers the remainder.
- Actual cash value (ACV): What your car is worth at the time of a claim, accounting for depreciation. This is the amount your insurer pays out if your car is totaled, not what you paid for the vehicle.
- Uninsured motorist coverage (UM): Covers your costs when you’re hit by a driver who carries no insurance at all.
- Underinsured motorist coverage (UIM): Covers the gap when the at-fault driver’s liability limits aren’t high enough to pay for your full damages.
- Personal injury protection (PIP): Covers medical expenses — and sometimes lost wages or child care — for you and your passengers after an accident, regardless of fault. Required in no-fault states.
- Medical payments coverage (MedPay): Covers medical bills for you and your passengers after an accident, regardless of fault. Narrower coverage than PIP.
- Gap insurance: Covers the difference between what your car is worth and what you still owe on your loan if the car is totaled. Only relevant for financed or leased vehicles.
- Force-placed insurance: Coverage your lender purchases on your behalf — and charges to you — if you let your required insurance lapse. Typically, more expensive and less protective than a policy you’d buy yourself.
