Answer in brief
Liability-only makes sense when the car is owned outright, its value is low enough that you could replace it from savings, and the annual cost of collision and comprehensive is a large share of that value—a common rule of thumb is 10% or more. It is a mistake when the car is financed or leased (lenders require full coverage), when you could not afford to replace it, when you live in a high-theft or severe-weather area and the car is worth more than a few thousand dollars, or when you drop liability limits rather than collision and comprehensive to save money.
The test
- 1
Is the car financed or leased?
If yes, full coverage is required. Stop here.
- 2
What is the car worth?
Look up its actual cash value—the amount an insurer would pay if it were totalled.
- 3
What do collision and comprehensive cost per year?
Find the lines on your declarations page.
- 4
Compare
If those two coverages cost 10% or more of the car's value each year, or the value minus deductible is small, liability-only is usually reasonable.
- 5
Could you replace the car tomorrow?
If losing the car would leave you without transport and without the money to replace it, keep collision a while longer or raise the deductible instead.
Situations where liability-only fits
- A paid-off car worth under about $5,000.
- A second or third household vehicle used occasionally.
- A reliable older car you plan to run until it stops, with savings to replace it.
- A driver whose premium is high for reasons unrelated to the car (young, urban, recent ticket), where collision would cost more than the car is worth within two years.
Situations where it is a mistake
- Dropping liability limits to the minimum to save money—see limits to choose.
- A car worth $10,000+ in a hail belt, hurricane coast or high-theft area—consider keeping comprehensive alone.
- Any financed or leased vehicle.
- A household with one car and no savings to replace it.

Questions & answers
At what car value should I go liability-only?
When collision and comprehensive cost 10% or more of the car's value per year, typically around $4,000–$6,000 for most drivers.
Can I have liability-only on a financed car?
No. Lenders require collision and comprehensive until the loan is paid.
Is liability-only enough for an old car?
Often yes for the car itself—but carry adequate liability limits and uninsured motorist coverage regardless of the car's value.
Terms used in this guide
- Actual cash value (ACV)
- What your car was worth just before a loss—replacement cost minus depreciation. The basis for deciding whether collision is worth keeping.
- Collision coverage
- Pays to repair or replace your own car after a crash, minus the deductible. Not included in a liability-only policy.
- Comprehensive coverage
- Pays for non-crash damage to your car—theft, weather, flood, fire, vandalism, animals, glass. Can be carried without collision.
- Deductible
- What you pay before collision or comprehensive pays. Liability coverages have no deductible.
