Buying a new car: the insurance steps to take

The insurance on a new car is usually arranged in a finance office, between the extended warranty pitch and the signature pages, by someone who has been at the dealership for four hours. It works out most of the time because auto policies are written to cover a newly acquired vehicle automatically for a period after purchase. It goes wrong when that automatic coverage is narrower than the buyer assumed, when the lender's requirements are not met in time, or when the old car is dropped from the policy before it has actually changed hands.

This guide is in the order the purchase happens: what to settle before you sign, what to do at the dealership, what the lender needs, whether to buy gap coverage and from whom, what to do with the car you are replacing, and the coverage choices that a new car makes worth revisiting. Read the section on automatic coverage first if the car is already in the driveway.

How automatic coverage works, and where it stops

Standard personal auto forms cover a vehicle you acquire during the policy period without being told, for a set number of days that varies by carrier and by whether the car replaces a listed vehicle or is an addition to the household. A replacement vehicle inherits the coverage of the car it replaces; an additional vehicle gets the broadest coverage on any car already on the policy. Both are traps in different directions. A new car replacing an old one that carried liability only is itself covered for liability only until you ask for more. And an additional car on a policy where no vehicle carries collision has no collision coverage, however new it is.

The period also runs from the date of purchase, not from the date you get around to calling. Some forms give a longer window for liability than for physical damage, and a few give none at all for physical damage on an additional car unless it is reported within days. The safe assumption is that automatic coverage exists to get you home from the dealership and no further, and that the call to add the car, with its VIN, should be made before the car is driven away.

Before you sign: quote the actual car

Two cars at the same price can carry very different premiums. Carriers rate by make, model and trim using the cost of repairing that specific vehicle, how often it is stolen, how badly its occupants and other people are hurt in crashes, and what its parts cost. A trim with driver-assistance sensors in the bumper and windshield costs more to fix after a minor collision, and the premium reflects that even though the car may crash less often. Pickups and certain models are stolen at high rates in the Phoenix and Las Vegas markets, and comprehensive premiums follow.

Send the agent the VIN, or at least the year, make, model and trim, for each car you are seriously considering, and get the premium at the deductibles and limits you actually carry. It is also the moment to look at the liability limits on the whole policy. A financed car does not change what a lawsuit could take from you, but a new purchase is when people look at the policy at all, and limits set years ago for a first car are often too low for the household they now sit under.

At the dealership: the lender's requirements

A financed or leased car comes with insurance conditions in the contract. The lender requires comprehensive and collision coverage, usually with a deductible no higher than a figure it names, and requires that it be listed on the policy as loss payee, so that a physical damage claim is paid jointly and it is told if the policy cancels. A lease is stricter: the leasing company is named as additional insured as well as loss payee, and often requires liability limits above what the driver would otherwise carry.

The dealership will ask for proof of insurance before the car leaves; a digital ID card or the agent's binder confirmation is enough. The loss payee is added afterwards, and the lender will send a request for evidence within weeks. If that request goes unanswered, the lender buys force-placed coverage that insures only its own interest, at a premium added to your loan payment, and it can take months to unwind. Confirm the lender's exact name and mailing address from the contract and have the agent add it the same day.

Gap coverage: whether you need it and where to buy it

A new car loses value faster in its first years than a loan amortises, so for a period the loan balance exceeds what the car is worth. If the car is totalled in that period, the policy pays the actual cash value, the lender is owed the balance, and the difference is yours. Gap coverage pays that difference. It matters most with a small down payment, a long loan term, negative equity rolled in from the trade, or a lease, where it is usually built into the lease contract.

Suppose a buyer finances $36,000 on a car that sells for $38,000, with fees and the shortfall from the old loan added in. Eight months later the car is totalled and the carrier values it at $29,000. The loan balance stands at $34,500. Without gap coverage the buyer owes $5,500 on a car that no longer exists; with it, the gap endorsement pays that balance and the buyer starts over. The figures are invented, but the timing is typical: the gap is widest in the first year or two and closes as the loan is paid down.

The dealership sells gap coverage as a lump sum added to the loan, so you pay interest on it. Many carriers offer it as an endorsement on the auto policy for a smaller amount, and some offer new car replacement coverage instead, which pays for a new car of the same model rather than the depreciated value. The carrier version usually has to be added at purchase or within a short period of it and is limited to cars under a certain age, so it is a decision for the first week, not the first renewal. Ask what the dealership's product costs and what the carrier's costs, and cancel the dealership's if the carrier's is bought; a refund of the unused portion is normally available.

The old car: remove it after it is gone, not before

A trade-in changes hands at the dealership and can come off the policy the same day. A private sale is different. Until the title is signed over and the buyer has driven away, the car is yours and your liability coverage is what responds if the buyer crashes it on the test drive. Keep it on the policy through the sale, then remove it and keep the bill of sale and the title transfer receipt in case a ticket or a toll arrives in your name. In Arizona and Nevada the plate belongs to the owner and comes off the car at sale, which is worth knowing when a buyer offers to keep it.

If the old car stays in the household as a spare, it stays on the policy, and this is the moment to reconsider its coverage. A ten-year-old second car worth little may not justify collision coverage against its own deductible, and a car that will be driven rarely can be rated for pleasure use. Dropping it entirely, or letting it sit unregistered and uninsured, invites a lapse notice in the states that check registration against insurance electronically.

Coverage choices a new car makes worth revisiting

A new car is the right moment to look at the lines below the liability limits.

• Deductibles. A higher deductible on a new car lowers the premium; a lower comprehensive deductible is worth considering in the hail belt along the Wasatch Front and in southern Idaho, where a spring storm can dent every panel.
• Glass. Modern windshields hold cameras that need recalibrating after replacement, which raises the cost of a claim. Arizona carriers offer full glass coverage without a deductible as an option; elsewhere it is usually part of comprehensive and subject to the deductible.
• Rental reimbursement. A new car in a body shop waiting on parts can be out for weeks. The coverage pays a daily rental amount for a set number of days and is inexpensive.
• Original manufacturer parts. Some policies let the shop use aftermarket parts on cars past their first year or two; an endorsement requires original parts if that matters to you.
• Usage-based programs. A new car with a factory telematics connection can enrol without a plug-in device, and a careful driver with a short commute usually comes out ahead.

The order, and the timing traps

Kept to this sequence, the car is covered from the moment it is yours and the lender never has a reason to force-place.

• Before the test drive: get quotes on the cars in contention at the limits and deductibles you will actually carry.
• Before signing: raise liability and uninsured motorist limits if the review showed they were low. Utah drivers should confirm the personal injury protection limit carries over unchanged.
• At the dealership, before the car leaves: send the VIN and the lender's name to the agent and get written confirmation the car is bound with the coverage the lender requires.
• Within the first week: decide on gap or new car replacement coverage and cancel the dealership version if the carrier's was bought.
• After the trade or sale: remove the old car, keep the transfer paperwork, and confirm the plate is handled the way your state requires.
• When the declarations page arrives: check the VIN, the loss payee name and the deductibles against the contract. A wrong VIN is a claim dispute waiting to happen.
• At the first renewal: revisit the gap endorsement, which can be dropped once the loan balance falls below the car's value.

How to use this

Send us the VIN or the trim of the car you are considering, the lender's name, the sale contract for the old car if there is one, and your current declarations page. We quote the new car across the carriers we represent in Arizona, Nevada, Utah and Idaho, add the loss payee and the gap endorsement where they are warranted, and get the old car off the policy at the right moment. If the automatic coverage on your existing policy already reaches the new car with the right limits, we will say so and the only step is a VIN.
