Do I need full coverage on an old car?

The short version

State law generally does not require collision and comprehensive on a car you own outright. A lender or lessor commonly requires them while its financial interest remains. Once that contract no longer applies, compare the coverages’ yearly cost with the car’s estimated value, your deductible, the policy terms, and whether you could replace the car yourself. No single percentage answers the question for everyone.

When full coverage is required

If you’re financing or leasing your car, check the agreement before changing coverage. Lenders and lessors commonly require collision and comprehensive because the vehicle secures their financial interest. When that interest ends, state law generally does not require those physical-damage coverages, but your policy and circumstances still determine what protection you would give up.

Worth being clear on the terms: “full coverage” isn’t an official policy type. It commonly means liability plus collision and comprehensive, all subject to the policy terms. State law generally does not require collision or comprehensive, while most states require a form of liability coverage or financial responsibility. Other coverages may also be required depending on the state.

A better comparison than a percentage cutoff

There is no regulator-backed rule saying collision and comprehensive stop being worthwhile at 10% of a car’s value. A more useful comparison starts with the annual price of those two coverages, the car’s estimated current value, and the deductible — then adds the factors a percentage misses.

Under a standard policy, a total-loss settlement is commonly based on actual cash value and the applicable deductible, subject to the policy’s valuation method, limits, exclusions, and endorsements. Ask the insurer for the collision-and-comprehensive portion of the premium and how it would value the vehicle. Then consider whether losing the car would interrupt work or school and whether you have enough savings to replace it.

What you give up by dropping it

Dropping collision and comprehensive means you’re on your own for repairing or replacing the car after an accident, theft, or weather damage. It’s a reasonable trade for an older, lower-value car — less so for one you’d struggle to replace out of pocket.

The honest way to think about it: dropping full coverage means you’re self-insuring the car. That’s fine if losing the car would be an inconvenience you could absorb. It’s risky if this is your only vehicle and you’d have no way to replace it without going into debt. The right answer depends less on the car’s age than on whether you could comfortably cover its replacement yourself.

A few things that don’t change

Two points often get lost in this decision. First, dropping collision and comprehensive has no effect on your liability coverage — you’re still covered for damage you cause to others, which is the part the law actually requires. Second, cutting these coverages lowers your premium, but so do several other choices that don’t leave you exposed; it’s worth reviewing the other ways to lower your premium before deciding coverage cuts are your only option. If money is the main driver, sometimes a higher deductible on retained full coverage is a middle path worth pricing too.
