Liability vs. Full Coverage Car Insurance

“Liability only” and “full coverage” are the two main ways people describe a car insurance policy. The difference is simple: one pays for damage you do to others, and the other also pays for damage to your own car. The price difference is large. Here's how to decide.

What each one covers

	Liability only	“Full coverage”
Injuries and damage you cause to others	Yes	Yes
Damage to your car in a crash	No	Yes (collision)
Theft, weather, fire, vandalism, animals	No	Yes (comprehensive)
Required on a financed or leased car	No	Usually yes
Average cost in 2026	$1,580 a year (state minimum)	$2,922 a year

Averages: Experian, published September 9, 2026 (national averages for minimum and full coverage, 12 months to August 2026).

“Full coverage” isn't an official term. It usually means liability plus collision plus comprehensive, but limits and deductibles vary, so compare what's actually in each quote. For each coverage in detail, see understanding car insurance.

When full coverage makes sense

The car is financed or leased, since the lender will require it.
You couldn't afford to repair or replace the car from savings.
The car is newer or valuable, or is kept where theft, hail or flooding are common.

When liability only can make sense

The car is paid off and worth little. A common rule of thumb is to consider dropping collision and comprehensive when their yearly cost approaches 10% of the car's value.
You have savings to replace the car if it's written off or stolen.

A middle option is to keep comprehensive, which is usually the cheaper of the two, and drop collision.

When to reduce your auto insurance limits, and when not to

The coverages it makes sense to trim are the ones protecting your own car: drop collision or comprehensive on a low-value car, or raise their deductibles if you have savings to cover a bigger share of a claim.

Liability limits are the ones not to cut. They protect your savings, income and home if you injure someone, and state minimums are low compared with the cost of a serious crash. If anything, raise them as your assets grow. Good times to review everything: when a loan is paid off, when the car ages, when you retire or drive much less, and after a move to a new state with different requirements.

Keeping full coverage affordable

If you need full coverage, you don't have to accept the first price. Compare insurers, choose deductibles you can afford, and ask for every discount. See cheap full coverage car insurance.

What full coverage costs where you live

The gap between liability only and full coverage depends heavily on your state. Average full-coverage premiums ranged from $1,523 a year in New Hampshire to $4,181 in Maryland in Experian's 2026 data. See every state in the cheapest and most expensive states. Your own driving record moves the price too: Experian's 2026 averages were $2,112 a year for a clean record and $2,515 with one violation, across all coverage levels.

A worked example (illustrative figures)

Say your car is worth $4,000, your collision and comprehensive together cost $700 a year, and your deductible is $1,000. The most those coverages could ever pay after a total loss is $3,000 ($4,000 minus the deductible), and you pay $700 a year for that protection. After a few years the premiums add up to more than the car is worth. If you could replace the car from savings, dropping both, or at least collision, is reasonable. If losing the car would leave you unable to get to work, keeping them may still be worth it.

Leased and financed cars

Lenders and leasing companies require collision and comprehensive, often with a maximum deductible. Leases frequently require liability limits above your state's minimum too, so check the agreement. Once a loan is paid off, the decision is yours. It's a good moment to review the policy.

Quick answers

Is full coverage required by law? No. States require liability (and in some states PIP or uninsured motorist cover). Collision and comprehensive are required only by lenders.

Does full coverage pay if the accident was my fault? Yes. Collision pays for your car whoever caused the crash, minus the deductible. Liability pays the other side.

Does liability cover my car if someone else hits me? Your liability doesn't. The other driver's liability pays for your car if they were at fault, and your uninsured motorist cover may help if they have no insurance.
