New Hampshire Auto Insurance at a Glance

  • Legal requirement: None — the only state with no mandatory insurance law
  • If carried: 25/50/25 minimum liability ($25k injury per person / $50k per accident / $25k property)
  • Alternative to insurance: $25,000+ deposit with the State Treasurer, or a surety bond
  • Fault system: At-fault (tort) — PIP is optional, never mandatory
  • Average minimum coverage: $455 per year, if carried
  • Average full coverage: $1,555 per year
  • Regulator: New Hampshire Insurance Department

New Hampshire doesn't require car insurance. Full stop — that part's true, and it's the only state in the country you can say that about. What's not true is the version of that fact everyone repeats at parties: that you can drive here with nothing behind you if something goes wrong.

The Myth: "New Hampshire Doesn't Require Insurance"

Technically correct. New Hampshire is the sole holdout among all 50 states — no statute forces a registered vehicle owner to buy an auto policy. People hear that and assume it means driving is a free-for-all here, financially speaking. It isn't.

The Reality: Financial Responsibility Law

RSA 264:22 fills the gap the insurance mandate leaves. It requires every driver to prove they can cover damages they cause. Most people do that by buying a policy that meets 25/50/25 liability — $25,000 per person in bodily injury coverage, $50,000 per accident, $25,000 for property damage. That's the exact same floor NH-sold insurance policies are held to.

Skip insurance entirely and the law still wants its proof. You can deposit $25,000 or more in cash or securities with the State Treasurer, or post a surety bond for the same amount. Almost nobody does this. Tying up $25,000 in cash to avoid a few hundred dollars a year in premiums isn't a trade most drivers take once they run the math.

What Happens Without Insurance or a Deposit

Say a driver skips both — no policy, no state deposit — and causes a crash on I-93 outside Manchester. There's no insurer to negotiate the claim, cap the payout, or provide a legal defense. The at-fault driver owes the other party's medical bills and repair costs directly, personally, with no ceiling tied to a policy limit. A DUI or an at-fault accident with no coverage in place typically triggers a court-ordered Certificate of Financial Responsibility — New Hampshire's equivalent of an SR-22 — usually for three years, and a license suspension until it's filed.

Why the "Free State" Still Has Cheap Insurance

Here's the part that surprises people: New Hampshire drivers who do carry insurance pay some of the lowest premiums in the country anyway. Minimum coverage averages around $455 a year, full coverage around $1,555 — both well under the national numbers. No mandate doesn't mean high risk; it just means the state trusts drivers to make the calculation themselves, and most of them land on buying a policy.

  • Buy at least 25/50/25: it matches what the law would demand from you anyway after a violation.
  • Keep UM/UIM coverage: insurers must offer it, and declining it in writing removes a real safety net.
  • Don't bank on the deposit option: $25,000 in tied-up cash rarely beats a modest annual premium.
  • Ask about PIP: it's optional here, unlike no-fault states, but it still pays your own medical bills first.

The New Hampshire Insurance Department oversees every carrier licensed to sell policies in the state and fields consumer complaints — worth checking before signing with an unfamiliar insurer, mandate or not.

"No insurance required" is the headline. "You still owe the money either way" is the actual law.
