How does insurance work when buying a used car?
Getting covered
If you already have an auto policy, it may extend coverage to a newly purchased car for a short period, often 7 to 30 days, depending on the insurer. But it's safest to add the car to your policy before you drive it.
If you're financing, the lender will require comprehensive and collision coverage to protect their investment. You'll need to provide proof of insurance before taking delivery.
If you're paying cash, you only need to meet your state's minimum liability requirements, though full coverage is still wise for a car you can't afford to replace.
- Call your insurer before you buy to get a quote and add the car.
- Have the VIN handy—insurers need it to give an accurate quote.
- If you're financing, the lender may require a specific deductible (often $500 or less).
- Gap insurance may be offered by the dealer or your insurer—consider it if you're financing.
Cost factors
Insurance costs for a used car depend on the car's value, safety features, repair costs, and your driving record. A used car may be cheaper to insure than a new one, but not always—some models have expensive parts.
If you're switching from an old car to a newer used one, your premium may go up. Get quotes before you buy so you know the full cost of ownership.
You can often save by bundling policies, raising your deductible, or asking about discounts for safety features.
Common mistakes
- Assuming your current policy automatically covers a new purchase for an unlimited time—grace periods are limited.
- Skipping gap insurance when financing, leaving you on the hook for the difference if the car is totaled.
- Not shopping around for insurance before buying, which can lead to a costly surprise.
