Guide to Insurance for New Cars

Q: What happens if I don't add my new car to my policy in time?

If you miss your insurer&#8217;s grace period (usually seven to 30 days), your new car may not be covered, leaving you responsible for the full cost of any accident. Letting your coverage lapse can also raise your rates and create legal issues if you&#8217;re caught driving uninsured. It&#8217;s best to update your policy as soon as possible rather than waiting until the grace period is about to expire.

Q: Do I need full coverage on a new car?

If you&#8217;re financing or leasing, your lender will almost always require full coverage — meaning comprehensive and collision coverage in addition to liability. If you&#8217;re buying the car outright, full coverage isn&#8217;t legally required, but it&#8217;s often recommended for new vehicles given their higher value and repair costs.

Q: What is gap insurance and do I need it for a new car?

Gap insurance covers the difference between your car&#8217;s actual cash value and what you still owe on your loan or lease if it&#8217;s totaled or stolen. Because new cars depreciate quickly, this gap can be significant in the first few years of ownership. Lenders typically require gap insurance for financed or leased vehicles for this reason.

Key Takeaways: Insurance for New Cars

New cars typically cost more to insure than used vehicles due to higher vehicle values and more expensive repairs.

All states except New Hampshire require auto insurance before you drive a new vehicle off the lot.
Full coverage is recommended for most new cars and is usually required for leased or financed vehicles.
New car replacement will provide you the full cost of a new car rather than your car’s actual cash value if it’s totaled or stolen.

Do You Need Insurance Before Buying a New Car?

Technically, you can buy a car without insurance. However, you won’t be able to drive it off the lot until your car is insured. The one exception is if you live in New Hampshire and are buying your car outright.

Auto insurance protects you from paying out of pocket for the full cost of an accident. If you’re leasing or financing your car, you’ll typically be required by the lender to get comprehensive and collision coverage in addition to liability coverage.

How Auto Insurance Works When Buying a New Car

You have two options when insuring a new car: You can sign up for a new policy or transfer your existing policy to cover your new vehicle. Signing up for a new policy also applies if you already have an insurance policy but are looking to switch providers when you insure your new car.

Starting a New Policy

If you choose to start a new policy, shop around to find the best coverage within your budget. Even if you haven’t decided on the exact car you want to buy, you can get insurance quotes for your top contenders to get an idea of how the make and model will impact your rates.

It’s a good idea to request at least three quotes from different companies to compare premiums, but make sure to use the same information for each request to make it easier to compare rates directly and choose the right match for your new vehicle. You should know your vehicle identification number (VIN) when applying for new coverage to speed up the quoting process.

If you’re looking to start a new policy, compare the quotes you receive in detail. Going over your options for coverage, limits, and deductibles is just as important as comparing rates.

NOTE

If you’re switching providers, make sure your new policy is in effect before you cancel your current policy. A lapse in coverage will cause your rates to increase, and if you get in an accident without insurance, you’ll have to pay out of pocket for any losses and could face legal ramifications.

In addition, you’ll want to look into how your potential insurer handles claims. Customer service with 24/7 availability and quick responses will improve the claim-filing process. The easiest way to find information on a company’s service is to check customer satisfaction ratings with an accredited rating agency like J.D. Power.

Adding a New Car to an Existing Policy

If you’re adding your new vehicle to an existing policy, all you need is proof of your current insurance to drive your car off the lot. Insurance companies generally offer a grace period of seven to 30 days to adjust your policy after you purchase a new vehicle. During the grace period, the coverage from your insurance policy applies to your new vehicle.

The grace period allows you to reassess your coverage needs and budget, but it’s always best to update your policy as soon as possible to ensure you don’t forget. If you’re replacing your old car with your new one, you’ll need to also remove the old one from the policy. If you’re simply adding the new car, you’ll likely also get a multi-car discount.

Auto Insurance Coverage You Need

Regardless of how you purchase a new car, you must meet your state’s minimum insurance requirements. While these requirements differ by state, below are some of the coverages you can expect to need.

Bodily injury liability coverage: Liability coverage covers damage or injuries to other parties in accidents where you are at fault. Bodily injury, specifically, covers others’ medical expenses for injuries. Florida and New Jersey are the only states that currently do not require bodily injury liability coverage.
Property damage liability coverage: The covers damage that you cause to other people’s property, including vehicles.
Uninsured/underinsured motorist coverage: When an uninsured or underinsured driver hits you, uninsured motorist coverage (UM) and underinsured motorist coverage (UIM) take care of your expenses.
Medical payments coverage or personal injury protection: Medical payments coverage (MedPay) pays for your and your passengers’ medical expenses that result from car accidents. MedPay is only available in some at-fault states. Personal injury protection (PIP) includes medical payments coverage and other other documented losses, such as lost wages and child care costs. PIP is only available in no-fault states.

Other insurance coverage requirements depend on whether you are buying, leasing, or financing a new car.

Buying a Vehicle

If you are buying your car outright, you only need to meet your state’s minimum coverage requirements. However, it’s wise to get higher limits than the minimum required ones for added financial protection. You can also choose to add full coverage to your policy, and you may consider looking for an insurer that offers new car replacement coverage.

Leasing or Financing a Vehicle

If you’re leasing or financing a new car, you’ll likely also need the following coverages:

Collision coverage: This covers damage to your vehicle caused by crashes, regardless of fault.
Comprehensive coverage: Together with collision coverage, comprehensive is considered part of a full coverage policy. It covers damage to your car caused by non-collision events, such as vandalism or weather.
Gap insurance: Lenders usually require this because it helps pay for the difference between your car’s actual cash value and what you still owe if it’s totaled.

A bank or dealership may require certain insurance limits for a leased or financed car. These limits ensure you have the means to keep paying your lease or loan if you get into an accident.

Additionally, a leasing company may impose a maximum deductible amount to prevent the potential burden of a high deductible and help ensure that the car will be repaired if needed.

GOOD TO KNOW

It is a dealership’s responsibility to insure its vehicles in the event of possible damages, not your responsibility as a potential buyer. However, dealer insurance only covers test drives, so you will not have protection once you buy the car.

How Does Buying a New Car Affect Insurance Rates?

Buying a new car often increases your insurance premium, though the exact impact depends on the vehicle you choose and your individual risk profile. Because new cars typically have higher market values and cost more to repair or replace than used vehicles, insurers generally charge higher premiums to account for the increased financial risk.

Several factors influence how much you’ll pay, including:

Make and model
Model year
Purchase price
Title and damage history
Mileage
State and ZIP code
Deductibles
Age
Marital status
Homeownership
Your driving records, including any at-fault accidents
Coverage options (i.e., the more coverages you get, the higher your rates)
Provider (different car insurance companies charge different rates for similar products and services)
Gender (except in California, Hawaii, Massachusetts, Michigan, Montana, North Carolina, and Pennsylvania)
Credit score (except in California, Hawaii, Michigan, and Massachusetts)

Vehicles will generally have cheaper insurance rates if they have low repair costs, strong safety records, or anti-theft features.

All other things being equal, if you replace an older car with a newer one, you can expect your premium to increase. For example, if you maintain the same coverages on your policy, your driving record hasn’t changed, you haven’t moved, etc., trading in a 2016 Honda HR-V for a 2026 model will result in a higher insurance rate.

STATS

As of 2026, the average cost of a new car is approaching $50,000, with no manufacturers producing new cars under $20,000.¹

Recap

Selecting the right insurance is a key part of the car buying process, whether you’re starting a new policy or updating an existing one. All states require car insurance except New Hampshire (though you still need to be able to meet financial obligations if you’re in an accident), and having adequate coverage will help protect your vehicle and your finances.

While new cars often cost more to insure than used vehicles, comparing quotes, selecting appropriate coverage limits, and taking advantage of available discounts can help keep premiums manageable. Reassess your policy annually to avoid overpaying for coverage you don’t need.

Frequently Asked Questions

Do I need insurance before buying a new car?

Yes, in nearly every state you must have an active auto insurance policy before you can drive a new car off the lot. New Hampshire is the only exception, though you’ll still need to prove you can cover damages if you’re in an accident. If you’re financing or leasing, your lender will require proof of insurance, typically including comprehensive and collision coverage, before you take possession of the vehicle.

What happens if I don't add my new car to my policy in time?

If you miss your insurer’s grace period (usually seven to 30 days), your new car may not be covered, leaving you responsible for the full cost of any accident. Letting your coverage lapse can also raise your rates and create legal issues if you’re caught driving uninsured. It’s best to update your policy as soon as possible rather than waiting until the grace period is about to expire.

Will my insurance pay if I total a brand-new car?

If you have collision coverage, your insurer will pay out the car’s actual cash value at the time of the accident, minus your deductible — not what you originally paid for it. Without collision coverage, you’re responsible for all repair or replacement costs yourself. Because new cars depreciate quickly, financed buyers can end up owing more on the loan than the payout covers unless they have gap insurance or new car replacement coverage.

Is insurance more expensive for new cars or used cars?

Generally, new cars cost more to insure because they have higher market values and cost more to repair or replace than used vehicles. However, this isn’t a hard rule — a heavily used older car can sometimes cost as much to insure as a new one, and newer vehicles often have better safety ratings that can offset some of the higher premium. Your specific rate ultimately depends on the make and model, your driving record, and the coverage you choose, not just the car’s age.

Do I need full coverage on a new car?

If you’re financing or leasing, your lender will almost always require full coverage — meaning comprehensive and collision coverage in addition to liability. If you’re buying the car outright, full coverage isn’t legally required, but it’s often recommended for new vehicles given their higher value and repair costs.

What is gap insurance and do I need it for a new car?

Gap insurance covers the difference between your car’s actual cash value and what you still owe on your loan or lease if it’s totaled or stolen. Because new cars depreciate quickly, this gap can be significant in the first few years of ownership. Lenders typically require gap insurance for financed or leased vehicles for this reason.
