Which States Have No Car Insurance Requirement

No state requires zero car insurance, but New Hampshire stands alone

Every U.S. state except New Hampshire requires you to carry some form of auto liability insurance. New Hampshire is the only state that does not mandate insurance, though even there you must prove you can pay for damages if you cause an accident — usually by posting a cash bond or surety bond with the state.

The reason every other state requires insurance is straightforward: liability coverage protects the other driver if you cause a crash. Without that requirement, an uninsured driver who hits someone could leave them with medical bills and vehicle damage they have no way to recover. States use insurance requirements to shift that risk away from victims and onto drivers.

If you live in New Hampshire and choose not to buy insurance, you will need to register your vehicle under the state's "self-insurance" program, which requires posting a bond equal to the state's minimum liability limits. This bond stays in place for the life of your registration and can be claimed against if you cause an accident.

Key Takeaways

• New Hampshire is the only state without a mandatory car insurance requirement, but drivers must post a cash or surety bond instead to cover potential damages.
• All other 49 states require minimum liability insurance coverage before you can register a vehicle or drive legally.
• Minimum coverage amounts vary by state, typically ranging from $15,000 to $25,000 per person for bodily injury liability.
• Even in states with insurance requirements, some drivers choose to go uninsured and face fines, license suspension, and legal liability if they cause an accident.

How New Hampshire's self-insurance option works

New Hampshire allows drivers to register a vehicle without insurance if they post a surety bond or cash deposit with the state Department of Motor Vehicles. The bond amount must equal the state's minimum liability limits: $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage.

A surety bond is a contract between you, a bonding company, and the state. The bonding company guarantees the state that if you cause an accident, the bond will cover damages up to the limit. You pay the bonding company a fee — typically a percentage of the bond amount — and the bond remains active as long as you own the vehicle and maintain registration.

A cash deposit works the same way but requires you to deposit the full amount with the DMV directly. Few drivers choose this route because it ties up thousands of dollars that you cannot access or invest. A surety bond costs far less upfront but requires you to may have access to for one, which means having a clean driving record and good credit.

Minimum insurance requirements in the other 49 states

Every state except New Hampshire sets a minimum liability insurance limit that you must carry before registering a vehicle. These minimums vary, but most states require at least $15,000 to $25,000 per person for bodily injury liability and $25,000 to $50,000 per accident.

Some states use a different format called "combined single limit," which pools bodily injury and property damage into one number. For example, Florida requires $10,000 combined single limit, meaning your insurance covers up to $10,000 total for all damages from one accident, whether that damage is to a person or a vehicle.

A few states also require uninsured motorist coverage, which protects you if you are hit by a driver without insurance. This coverage is optional in most states but mandatory in a handful, including Kentucky, New York, and North Carolina.

What happens if you drive uninsured in a state that requires it

Driving without insurance in any state except New Hampshire carries real penalties. If you are pulled over and cannot show proof of insurance, you will receive a citation. Fines range from $100 to $500 or more depending on the state and whether it is your first offense.

A second or third uninsured driving citation can result in license suspension, which means you cannot legally drive until you purchase insurance and file proof with the state. Some states require you to file an SR-22 form, which is a certificate of financial responsibility that your insurance company submits to the DMV on your behalf.

If you cause an accident while uninsured, you become personally liable for all damages. The other driver can sue you for medical bills, lost wages, vehicle repairs, and pain and suffering. A judgment against you can follow you for years and result in wage garnishment or bank account levies.

Why New Hampshire allows self-insurance when other states do not

New Hampshire's approach reflects the state's philosophy of personal responsibility and minimal government regulation. Rather than forcing drivers to buy insurance from a private company, the state allows drivers to prove they can cover damages themselves through a bond or cash deposit.

In practice, very few New Hampshire drivers use the self-insurance option. Most still buy traditional liability insurance because it is cheaper than posting a bond and because insurance provides additional protections like collision and comprehensive coverage that a bond does not.

The self-insurance system also requires drivers to maintain a clean record. If you cause an accident while self-insured, the state can increase your bond requirement or revoke your self-insurance status and require you to buy traditional insurance going forward.

Comparing insurance costs across states with different minimums

States with higher minimum liability limits typically have higher average insurance premiums, though many other factors affect your rate: your age, driving record, the type of vehicle, and the insurance company you choose. A 30-year-old with a clean record in a state requiring $15,000 minimum coverage will pay less than the same driver in a state requiring $50,000 minimum, but the difference is usually modest — often $50 to $150 per year.

Some drivers in high-minimum states choose to buy only the state minimum to keep premiums low, while others buy higher limits for extra protection. Buying more than the minimum does not cost proportionally more — adding $100,000 in coverage might only increase your premium by $15 to $30 per month.

Moving to or from New Hampshire with a vehicle

If you move to New Hampshire from another state, you can register your vehicle under the self-insurance option once you establish residency, but you are not required to. You can continue buying traditional insurance if you prefer, and many people do.

If you move away from New Hampshire to a state that requires insurance, you must purchase a policy before registering your vehicle in the new state. Your self-insurance bond or cash deposit will no longer satisfy the requirement, and you cannot register the vehicle without proof of insurance.

Frequently Asked Questions

Can I drive in another state if I am self-insured in New Hampshire?

Your New Hampshire self-insurance status is only valid in New Hampshire. If you drive into another state, you must have traditional liability insurance that meets that state's minimum requirements. Many drivers who use New Hampshire's self-insurance option buy a short-term policy when traveling out of state.

What if I cannot get a surety bond in New Hampshire?

If you have a poor driving record or bad credit, bonding companies may refuse to issue a bond. In that case, you must purchase traditional liability insurance to register your vehicle. You can shop around — different insurance companies have different underwriting standards, and some will insure drivers others reject.

Is New Hampshire's self-insurance cheaper than buying insurance?

A surety bond typically costs $100 to $300 per year, which is less than most liability insurance policies. However, a bond covers only liability — it does not cover collision, comprehensive, or medical payments coverage. If you want those protections, traditional insurance is your only option.

Do all 49 other states have the same minimum insurance requirements?

No. Minimums vary significantly. Some states require as little as $15,000 per person for bodily injury, while others require $50,000 or more. Check your specific state's DMV website to learn the exact minimums that explore where you live or plan to move.

What is an SR-22 form, and when do I need one?

An SR-22 is a certificate of financial responsibility that your insurance company files with your state's DMV. You typically need one if you have been convicted of driving without insurance, driving under the influence, or certain other violations. The form proves to the state that you are insured and must be maintained for a set period, usually three years.
