When to Drop Full Coverage on an Older Car: The One-Minute Rule

Picture a 13-year-old sedan worth $4,000. Collision and comprehensive on it run $900 a year. Take off the $1,000 deductible. The biggest check the insurer could ever write for that car is $3,000. You'd pay that much in premiums in about three years and four months. And the car's value, which caps what you could collect, never shows up on anything the insurer sends you.

Run the one-minute rule on your car

Your comprehensive coverage, not collision, usually pays

Those are example numbers, and your own premium won't match them. The pattern is common, though. People miss it when they renew on autopilot: the premium arrives as a familiar number on a familiar bill, while the car keeps losing value. On an older car, almost any real crash ends in a total loss, so you aren't really buying repair coverage. You're buying a one-time check for the car's value minus your deductible.

That isn't a case for dropping coverage on every old car. In some situations the math points one way and the right call is the other.

While you have the policy out

Collision and comprehensive are only part of the bill. Whichever way you decide on them, a few other lines are worth checking at the same time.

  1. Liability limits. A lot of people carrying full coverage on an old car also have thin liability limits, which is backward. Liability is what protects your house and savings if you hurt someone. Consumer Reports' recommended floor starts at $100,000 per person.
  2. Uninsured and underinsured motorist coverage. In some states it comes with a property damage option, which can pay for your car when a driver with no insurance hits you. Your insurer can tell you what your state allows.
  3. The second car. A household runs the numbers on the oldest vehicle in the driveway and never looks at the 11-year-old one parked next to it, which may come out even worse.
  4. Your real mileage. Older cars owned by people over 50 often get driven a lot less than the policy assumes. It's one of the inputs you're allowed to correct.

Those lines matter whatever you do about collision. The article covers the decision itself: the one-minute rule, when to keep the coverage whatever the math says, and the options between full coverage and none.
