Do You Need Insurance on a Car You're Not Driving?

In most cases, yes, as long as the car is still registered. States generally attach the insurance requirement to the registration, not to how often the car moves. Pennsylvania's Department of Transportation says state law requires every vehicle owner to maintain liability insurance on a currently registered vehicle, and a car sitting untouched in your driveway is still currently registered. If you want to stop paying for coverage on a car you're not driving, the legal route is usually to take the car off the road on paper first, by surrendering the plates and registration, and only then cancel the policy.

Why not driving it doesn't end the requirement

Liability insurance exists to pay for injuries and property damage you cause other people. A registered car can be driven at any moment, by you or by anyone with the keys, so states treat the registration as the trigger rather than your actual mileage. Insurers also report cancellations, which is how an owner who cancels the policy on a parked car can end up with a suspension notice even though the car never left the garage. Pennsylvania's rules, for example, can run from the date the insurance company reports that the coverage ended.

What happens if you just cancel the policy

Canceling insurance while the plates are still active usually creates a lapse in coverage on a registered car, and states treat that as a violation whether or not you drove. Two examples from state motor vehicle agencies show how it plays out.

• Pennsylvania: a lapse in insurance results in a three-month suspension of the vehicle's registration, unless the lapse lasted less than 31 days and the owner proves to PennDOT that the vehicle was not operated during it. A restoration fee and proof of insurance are required before the registration is restored.
• New York: the DMV says you must surrender your plates and registration before you cancel the vehicle's liability insurance. If you don't turn in the plates, the DMV will suspend the registration and can suspend your driver license.

Beyond the state penalties, a gap in your insurance history can make your next policy harder or more expensive to buy, which is the opposite of what you were trying to accomplish by canceling.

How to take a car off the road the right way

If the car really is going to sit for a long stretch, the clean way to stop paying for it looks like this. Check your own state's motor vehicle agency for the exact forms, because the details vary.

• Decide how long the car will sit. If it's a few weeks, keeping the policy is usually simpler than surrendering and later restoring the registration.
• Surrender the plates and registration first. In New York you complete form PD-7 and return the plates by mail or at a DMV office. In Pennsylvania, PennDOT must receive the plates and registration card no more than 30 days after the insurance is canceled; plates received later lead to a three-month registration suspension.
• Keep the receipt or confirmation from the motor vehicle agency, then cancel or change the policy and keep written confirmation of the end date.
• Keep the car off public roads while it's unregistered and uninsured, since it can't legally be driven there.
• Before you drive it again, buy insurance and restore the registration first, not after.

Seasonal storage: the plates-off option

Some states build in a way to park a car for part of the year. The New York DMV says you can surrender your vehicle plates and cancel liability insurance when you take your vehicle off the road for the winter, then reinstate the registration later. That's the same order of operations as above, just planned around a season. If you store a car every winter, ask your DMV whether it offers a similar temporary surrender, and ask your insurer what it offers for a car in storage.

If you keep the registration, you can usually trim the coverage instead

Sometimes surrendering the plates isn't worth the hassle, for example when the car will sit for a couple of months between uses. In that case the liability coverage has to stay, because it's the part the state requires, but the optional coverages are worth a second look.

The Texas Department of Insurance describes comprehensive coverage as paying if your car is stolen or damaged by fire, flood, vandalism, or something other than a collision. Those risks don't go away when a car is parked, so comprehensive is often the coverage people keep on a car they aren't driving. Collision coverage pays to repair or replace your car after an accident, which is a risk that mostly disappears when the car doesn't move. There is one big exception: Texas's guide notes that if you still owe money on your car, your lender will require collision and comprehensive coverage, so check your loan or lease before dropping either.

What about a car that doesn't run?

A car that can't be driven is still registered unless you surrender the registration, so the same logic applies. A broken-down car sitting in the driveway with active plates generally still needs the state-required insurance. If repairs will take months, surrendering the plates and restoring them once the car runs again may cost less than insuring a car that can't move.

The bottom line: not driving a car doesn't end the insurance requirement, the registration does. If you want to stop paying, surrender the plates and registration first, then cancel the policy, and keep proof of both dates. If you'd rather keep the car registered, keep the required liability coverage and look at trimming the optional coverages instead.
