Car Insurance in New Hampshire

Do you have to buy car insurance in New Hampshire?

No. New Hampshire is the only state that does not make drivers buy liability insurance. You can register a car and drive without a policy.

That freedom comes with a catch. The state expects you to be able to pay for the harm you cause. If you are in an at-fault crash and cannot show that, the DMV can suspend your license and registration. The usual proof is an insurance policy. The alternative is showing you have enough of your own money to cover the damage, which few people can spare.

Most drivers buy coverage anyway. About 90% of registered vehicles were insured in 2023, according to figures the Insurance Department cited. Neighboring Massachusetts and Maine, which require insurance, average about 93%. If you finance the car, the lender will usually require collision and comprehensive coverage.

What happens if you cause a crash without insurance?

The trouble starts after the crash, not when you register the car. The state’s own fiscal analysis says the financial responsibility law is enforced only once an accident happens.

After a crash you cause, the other driver can claim against you personally. If you cannot show you are able to pay, the state can suspend your license and registration. Getting them back later costs $100 for the license and $25 for the registration.

Here is an example with invented numbers. You skip insurance to save money. In April you rear-end a car and the other driver has $40,000 in medical bills and $9,000 in car damage. Without a policy, nobody else pays. The claim lands on you, and your driving privileges are at risk until it is resolved.

A crash while uninsured can also lead to an SR-22 requirement, covered below.

Lawmakers tried to change this in 2026. House Bill 1558 would have required proof of insurance at registration from 2027. Committee members voted 16-0 against it in February, and the full House agreed by voice vote. Nothing replaced it.

What coverage comes with a New Hampshire policy?

Buy a policy and three things come with it, whether you ask or not.

• Liability limits of at least 25/50/25. That means $25,000 for one injured person, $50,000 for everyone hurt in one crash, and $25,000 for property damage. The Insurance Department says these are the lowest limits insurers sell.
• Uninsured motorist coverage at your liability limits. It pays your injuries when a driver with no insurance, too little insurance or a hit-and-run driver is at fault. It does not fix your car.
• Medical payments of at least $1,000. It pays your medical bills, no matter who caused the crash, for three years after the injury.

Collision and comprehensive coverage fix your own car. The state does not require either. Your lender will. So the choice is usually yours when you own the car outright.

New Hampshire is a fault-based state. There is no personal injury protection, and the driver who causes a crash is responsible for the other side’s losses. Our no-fault versus at-fault guide explains what that means in practice.

Friends can drive your car too. Liability policies here cover a driver who has your permission. A licensed child in your household is an insured driver, and an insurer may charge for that child, even if the child is away at college. Our state minimum lookup tool lets you compare limits with other states.

Is the state minimum enough in New Hampshire?

For most people with a job, a home or savings, no. The minimum caps what your insurer pays. Anything above the cap is claimed from you.

Take another invented example. You cause a crash that puts one driver in the hospital with $80,000 in bills. At 25/50/25, your insurer pays $25,000 toward that person. The other $55,000 can be pursued from your paycheck or your savings. At 100/300/100, the same claim is paid in full.

The same limits protect you. Your uninsured motorist coverage matches your liability limits. If a driver with the minimum hurts you badly, your own policy picks up the shortfall, but only up to the limit you chose. A higher liability limit raises both protections at once.

A simple way to choose: add up your savings, your home equity and what a court could take from your paycheck. Pick liability limits near that total. Our liability limit checker helps with the math. If you have almost nothing a court could reach, the minimum is a defensible choice, but you carry the risk of being unable to pay.

Whether to add collision and comprehensive depends on what your car is worth. Our full coverage versus liability-only guide walks through that choice.

How much does car insurance cost in New Hampshire?

Less than the national average, though not by a fixed amount. NAIC’s 2024 figure is $1,073 per insured vehicle in the state, against $1,432 across the country. That is about 25% lower. It averages every driver and every coverage level, so it is a gauge, not a quote.

The gap shows up in each part of the policy. Liability averaged $517 here versus $813 nationally. Collision was $405 versus $516, and comprehensive $181 versus $283.

Published estimates for one clean-record driver look different, because they price specific coverage levels. They disagree with each other, which is normal.

One other analyst reported a much lower full-coverage average, and its own pages disagree with each other, so we left it out. Your price will depend on your record, town, car and insurer. The Insurance Department says it approves rate plans but does not set prices, and prices vary widely between companies.

Insurers may weigh credit history here, but state law says a higher premium cannot rest on credit alone. The Department also publishes a premium comparison survey of the top 35 insurers across nine territories of the state. Use it to see how far companies differ for the same sample driver.

What should you know before filing a claim?

Three New Hampshire rules help when you are arguing about money.

• Total loss. A car is usually a total loss when repairs would cost more than 75% of its fair market value. The insurer then pays that value, plus towing, storage and the title fee.
• Estimates. You pay for only one repair estimate. If the insurer asks for more, it pays.
• Lost value. Your own policy does not pay for diminished value, the drop in resale value after a repair. You can claim it from the at-fault driver’s insurer, but you must document it.

Also, the Department generally advises filing with your own insurer first when you have collision coverage. You may owe a deductible, but your insurer can recover it from the other side. Ask before you drive for a rideshare or food delivery app. The Department warns that personal policies may try to exclude delivery, though they cannot exclude liability below the minimums.

What if you need an SR-22 in New Hampshire?

An SR-22 is a certificate your insurer files with the DMV to prove you carry coverage. The DMV can require one if you are convicted of any DWI, of leaving the scene of a crash, or of reckless driving for a second time. You will get a letter, and your license cannot be restored until the filing is made.

Only an insurer licensed in New Hampshire can file it, and it cannot be faxed. Expect the filing to take 3 to 5 business days to process at the DMV. The usual period is three years. A later uninsured crash or similar event can add three more years. Ask the DMV’s financial responsibility unit to review your record before you let the policy end. Our SR-22 guide covers the cost and the steps.

Where else can you go on this site?

We have not yet published New Hampshire pages for cost by situation, SR-22 filing or city comparisons. Until they appear, these national pages fit what a New Hampshire driver is likely to ask:

• Minimum coverage by state puts 25/50/25 next to other states.
• Uninsured motorist coverage explained matters here because it is bundled in.
• How much is car insurance explains why quotes differ.

What to do next

1. Check whether you have a policy now. If your car is financed, you almost certainly must.
2. Read your declarations page. Note your liability limits, your uninsured motorist limits and whether collision and comprehensive are on it.
3. Compare your limits with what you own. If a serious crash could take your savings or home equity, ask for higher limits.
4. Get quotes from several insurers, with the same limits and deductibles in each. The Insurance Department’s comparison survey gives a starting point.
5. If the DMV sends an SR-22 letter, call an insurer licensed in New Hampshire right away. Keep the end date in writing.
6. If a claim goes wrong, write down dates and names, then call the Department’s Consumer Services unit at 603-271-2261.

Bottom line

If you have a car loan, a home or real savings, buy insurance and set liability limits well above the minimum. If you own almost nothing, the legal minimum is the floor, and driving without any policy still risks your license after a crash. Either way, check your own policy first.
