Insuring a new car: what to do before you drive off the lot

If you already have car insurance, your policy usually covers a newly bought car for a short grace period — often somewhere between a week and a month, depending on the insurer — but only with the same coverage as the car it replaces or the broadest coverage on your other cars. If you have no policy, you must buy one before you drive away. Either way, call your insurer with the new car's VIN before you sign, because a financed or leased car needs specific coverage on day one.

How your current policy treats a new car

Most personal auto policies include a "newly acquired auto" provision. The details vary by company and state:

• The grace period differs. Progressive's consumer guidance says insurers generally give "between 7 to 30 days" to add a new car, and that Progressive itself allows 30 days. Read your own policy's definition of a newly acquired vehicle to find your deadline.
• Coverage mirrors what you already have. If your old car carried only liability, the new car is not automatically covered for its own damage. Driving a new, financed car home with no collision or comprehensive coverage is a large risk.
• Replacement and additional cars may be treated differently. Some policies cover a replacement car automatically but require you to request coverage within a set time for an additional car, or give less time for physical damage coverage when none of your cars has it.
• No policy, no grace period. The provision only exists inside an active policy. A first-time buyer has nothing to extend.

The safest approach is not to rely on the grace period at all: add the car the day you buy it.

What the dealer and lender will ask for

Dealers usually ask for proof of insurance before they release the car. If you are financing or leasing:

• Collision and comprehensive are required, because the car is the lender's collateral.
• The lender must be listed on your policy as lienholder and loss payee, so claim checks for the car include them. You need the lender's name and mailing address from the contract.
• Deductible limits may apply. Many loan and lease contracts cap the deductible you can choose; check the paperwork.
• Leases often set liability limits above the state minimum. Read the lease's insurance section before you get quotes.

Coverage decisions to make before you sign

Gap or loan/lease payoff

A new car loses value quickly, and in the first years you can owe more on the loan than the car is worth. If it is totaled or stolen, a standard policy pays the car's actual cash value, not your loan balance. Gap insurance or an insurer's loan/lease payoff coverage covers some or all of the difference. Progressive, for example, describes its loan/lease payoff coverage as paying the difference up to 25% of the car's actual cash value, with limits that may vary by state. Many leases already include gap protection, and dealers sell their own. Compare prices before buying it at the finance desk; the gap insurance calculator shows how big your gap could be.

New car replacement

Some insurers offer new car replacement coverage, which pays to replace a totaled car with a new one of the same make and model rather than paying depreciated value, usually only for a limited window after purchase: one year at some insurers, up to five at others. It is a different product from gap coverage, and the two can complement each other. See new car replacement coverage.

Deductibles and limits

A more expensive car can make higher liability limits sensible, because it often signals more assets to protect. Revisit your deductibles too: a $1,000 deductible on a $45,000 car is a different decision from the same deductible on an older car.

Step by step: from showroom to driveway

1. Price the car before you commit. Ask your insurer for a quote using the VIN, or the year, make, model and trim, while you are still choosing (see check insurance costs before you buy a car). Insurance costs vary widely between models.
2. Read the finance or lease paperwork for required coverages, deductible caps and the lienholder's details.
3. Call your insurer or agent before signing. Give the VIN, purchase date, lender details and whether the car replaces another or is an addition.
4. Choose coverages: collision and comprehensive, gap or loan/lease payoff if needed, and any new car replacement option.
5. Get a new ID card showing the car, by email or in your insurer's app, to show the dealer.
6. Decide what happens to the old car. If you traded it in, remove it from the policy once the dealer takes it. If you are keeping it, it stays on the policy and may earn a multi-car discount.
7. Check the declarations page once it arrives to make sure the VIN, lienholder and coverages are correct.

If you are buying your first car

With no existing policy, you need coverage effective before you drive. Most insurers can quote and bind a policy the same day using the VIN, and email ID cards immediately. Shopping a few days before the purchase gives you time to compare (see what you need to get a car insurance quote and the quote comparison worksheet).

A hypothetical example

Say you buy a $38,000 car with $3,000 down and finance $35,000. A year later the car is totaled. Its actual cash value is $29,000 and you still owe $31,500. Without gap or payoff coverage, the insurer pays $29,000 minus your deductible, and you owe the lender about $2,500 plus the deductible for a car you no longer have. With gap coverage, the shortfall is covered under its terms.

Key takeaways

• An existing policy usually covers a new car for a limited time, often 7 to 30 days, but only with coverage like what you already carry.
• Financed and leased cars need collision and comprehensive from day one, with the lender listed as lienholder.
• Consider gap or loan/lease payoff coverage when you owe more than the car is worth.
• Add the car on the day you buy it rather than relying on the grace period.
• First-time buyers have no grace period and must buy a policy before driving away.
