Here's something that surprises most people: New Hampshire doesn't require you to buy car insurance. That's right—you can legally drive in the Granite State without an insurance policy. But before you cancel your coverage, here's what you need to know about how auto insurance actually works in New Hampshire and why most residents still choose to buy it anyway.

New Hampshire's Unique Approach: Financial Responsibility Instead of Mandatory Insurance

New Hampshire stands alone as the only state in America that doesn't mandate auto insurance for all drivers. Instead, the state operates under a financial responsibility law. This means you're not required to have insurance, but you are required to pay for any bodily injury or property damage you cause in an accident.

The financial responsibility requirements in New Hampshire are $25,000 for bodily injury or death to one person, $50,000 for bodily injury to two or more people in any one accident, and $25,000 for property damage. You can meet these requirements either by purchasing insurance or by depositing $100,000 in cash or securities with the state treasurer. As you might guess, most people find insurance to be the more practical option.

This system reflects New Hampshire's "Live Free or Die" philosophy, giving residents the freedom to choose how they demonstrate financial responsibility. Interestingly, it seems to work—only about 6-10% of New Hampshire drivers are uninsured, which is one of the lowest uninsured motorist rates in the entire country.

When Auto Insurance Becomes Mandatory in New Hampshire

While New Hampshire gives you the freedom to drive without insurance, that freedom comes with accountability. There are specific situations where the state will require you to carry insurance for three years:

First, if you're convicted of driving under the influence (DUI), you'll need to purchase and maintain auto insurance. The same goes for other serious violations like leaving the scene of an accident, vehicular homicide, or second and subsequent offenses of reckless driving. And if you cause an accident while uninsured, you'll be required to carry coverage going forward.

When insurance becomes mandatory, you'll need to file an SR-22 form with the state, which is essentially a certificate proving you're carrying the required coverage. This three-year requirement stays in place from the date of your conviction or the accident that triggered it.

What Coverage You Need If You Buy Insurance

If you do choose to purchase auto insurance in New Hampshire—whether voluntarily or because it's required—you must meet minimum coverage standards. The state requires what's known as 25/50/25 liability coverage: $25,000 in bodily injury coverage per person, $50,000 per accident, and $25,000 for property damage.

But here's what makes New Hampshire different: your policy must also include at least $1,000 in medical payments coverage and uninsured/underinsured motorist coverage that matches your liability limits. This means if you carry $25,000/$50,000 in liability, you automatically get the same amount in uninsured motorist protection. This requirement actually offers excellent protection, since it ensures you're covered if you're hit by one of those 6-10% of drivers who don't carry insurance.

Keep in mind these are just minimums. While $25,000 might sound like a lot, medical bills from a serious accident can easily exceed that amount. Many financial experts recommend carrying liability limits of at least $100,000/$300,000 to better protect your assets if you're found at fault in a serious accident.

How Much Does Auto Insurance Cost in New Hampshire?

Here's some good news: New Hampshire consistently ranks among the most affordable states for auto insurance. The average cost for full coverage in 2024 ranges from about $997 to $1,733 per year depending on which study you look at, but all sources agree that New Hampshire rates are significantly lower than the national average.

If you only need minimum coverage, you're looking at around $481 per year—that's about $40 a month. New Hampshire ranks fifth out of all 50 states for affordability, and second in the Northeast region. The state is even projected to see decreasing auto insurance costs in 2025, bucking the national trend of rising premiums.

Why is insurance so affordable here? Several factors contribute: relatively low population density means fewer accidents, harsh winters keep aggressive drivers in check, and the state's lack of mandatory insurance laws may create a more competitive market. Whatever the reason, New Hampshire drivers benefit from some of the best insurance rates in the country.

Should You Buy Insurance Even Though It's Not Required?

This is the question every New Hampshire driver has to answer for themselves. Legally, you can skip insurance if you're confident you can cover accident costs out of pocket. But consider this: the average cost of a car accident involving injuries is over $100,000. A single serious accident could wipe out your savings, force you to sell assets, or leave you with overwhelming debt.

For around $40-$150 per month, insurance transfers that financial risk to a company with deep pockets. You also get benefits like roadside assistance, rental car coverage, and protection if you're hit by an uninsured driver. If you're financing or leasing your vehicle, your lender will require full coverage anyway, so the choice is made for you.

The fact that 90-94% of New Hampshire drivers choose to carry insurance—despite not being required to—tells you something. Most people decide the peace of mind and financial protection are worth the relatively modest cost, especially in a state where insurance is already more affordable than most other places.

Getting Started with Auto Insurance in New Hampshire

If you've decided to purchase auto insurance, shopping around is crucial. Rates can vary significantly between insurers, and New Hampshire's competitive market means there are deals to be found. Get quotes from at least three different companies, comparing not just price but also coverage options, customer service ratings, and claims handling reputation.

When comparing policies, don't just settle for the minimum coverage. Consider higher liability limits, comprehensive and collision coverage to protect your own vehicle, and optional coverages like rental reimbursement or roadside assistance. Ask about discounts for bundling with homeowners insurance, maintaining a clean driving record, taking defensive driving courses, or installing safety features in your vehicle.

New Hampshire's unique approach to auto insurance reflects the state's independent spirit while still protecting its residents through financial responsibility laws. Whether you choose to buy insurance or self-insure, understanding your options and obligations is essential. For most drivers, the affordable rates and comprehensive protection make purchasing insurance the smart choice—even in the one state where you don't have to.

Frequently Asked Questions

Is New Hampshire really the only state that doesn't require car insurance?

+

Yes, New Hampshire is the only state in America that doesn't mandate auto insurance for all drivers. However, the state does require you to demonstrate financial responsibility, meaning you must be able to pay for damages if you cause an accident. You can meet this requirement either by purchasing insurance or by depositing $100,000 with the state treasurer.

What happens if I cause an accident in New Hampshire without insurance?

+

If you cause an accident while uninsured, you're personally liable for all damages and injuries. You'll also be required to purchase and maintain auto insurance for the next three years and file an SR-22 form with the state. The financial consequences of a single accident can be devastating, which is why most New Hampshire drivers choose to carry insurance despite not being required to.

Can I drive in other states without insurance if I'm from New Hampshire?

+

This gets complicated. While New Hampshire doesn't require you to have insurance, other states do. If you're driving in a state with mandatory insurance laws and you're stopped or involved in an accident, you could face penalties even though you're legally uninsured in your home state. For this reason alone, carrying insurance is recommended if you regularly drive outside New Hampshire.

Why is auto insurance so cheap in New Hampshire compared to other states?

+

Several factors contribute to New Hampshire's low insurance rates. The state has relatively low population density, which means fewer accidents overall. New Hampshire also has one of the lowest uninsured motorist rates in the country (only 6-10%), which reduces costs for insurers. Additionally, the competitive insurance market and the state's lack of mandatory coverage requirements may help keep prices down.

What's the minimum coverage I need if I buy insurance in New Hampshire?

+

If you purchase auto insurance in New Hampshire, you must carry at least $25,000 per person/$50,000 per accident in bodily injury liability, $25,000 in property damage liability, $1,000 in medical payments coverage, and uninsured/underinsured motorist coverage equal to your liability limits. However, many experts recommend higher limits to better protect your assets.

Do I need to carry proof of financial responsibility in my car?

+

New Hampshire doesn't require you to carry proof of insurance or financial responsibility in your vehicle if you're driving uninsured. However, if you do have insurance, it's wise to keep your insurance card with you. If you're required to carry insurance due to a violation or at-fault accident, you must maintain an SR-22 on file with the state for three years.
