Injured in New Hampshire? How Claims Work in the State Where Car Insurance Is Optional

In most states, an injury claim starts from a simple assumption: the person who hurt you carries liability insurance, because the law made them buy it. New Hampshire does not make that assumption — because, almost uniquely among the states, it does not make most drivers buy insurance at all.

That one fact shapes how injury claims actually play out in the Granite State more than any deadline or courtroom rule. So that is where this guide starts — before working through the fault rules, the three-year filing clock, and the much shorter traps that apply when a town or state agency is on the other side.

Live free, drive uninsured: the rule that makes New Hampshire different

As of 2026, New Hampshire generally does not require drivers to carry auto liability insurance. Instead, the state uses a financial responsibility system: drivers must be able to answer for the harm they cause, and certain drivers — typically after serious violations or an uninsured crash — can be ordered to file proof of insurance going forward. When a policy is written to satisfy those rules, state law (RSA 259:61) sets the familiar floor: $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage.

Most New Hampshire drivers do buy insurance anyway. But “most” is not “all,” and if you are hurt by one of the exceptions, your claim may run through your own policy’s uninsured motorist coverage rather than the other driver’s insurer. Two practical consequences follow:

• Your own policy matters more here than almost anywhere else. Uninsured and underinsured motorist coverage is not fine print in New Hampshire — it is often the claim. Dig out your declarations page and see what you actually carry.
• Your own insurer can become the adversary. A UM claim is still a negotiation, and your insurer’s interests stop lining up with yours the moment you file it. Policies also impose their own notice requirements and deadlines, which can be shorter than anything in a statute.

No-fault? No. New Hampshire is a straight at-fault state

New Hampshire is not a no-fault state. There is no personal injury protection mandate and no “tort threshold” you must clear before suing, the way there is in Massachusetts next door. The driver (or property owner, or business) who caused the harm is generally responsible for it, through their insurance if they have it. That makes evidence of fault — photos, witness names, the police report, prompt medical records — central to every New Hampshire claim from day one.

Partly your fault? You may still have a claim

New Hampshire applies modified comparative fault under RSA 507:7-d. You can recover as long as your share of the blame is not greater than the combined fault of everyone you are claiming against. Your recovery is then reduced by your percentage. Found 30% responsible for a crash with $100,000 in assessed damages? You would generally recover $70,000. Found 50% responsible — dead even — you can still recover half. Tip past that into being more at fault than the other side, and recovery is barred entirely.

Because everything turns on that percentage, it is heavily contested — and an adjuster’s early opinion that the accident was mostly your fault is a negotiating position, not a finding. Do not talk yourself out of a claim before anyone qualified has looked at the evidence.

The three-year clock — and the discovery-rule exception

Under RSA 508:4, most New Hampshire personal injury lawsuits must be filed within three years of the act or omission that caused the injury. That is more generous than many states, but it comes with the usual catch: an open insurance claim does not stop the clock. Only a filed lawsuit does, and cases need to be investigated and built long before filing day.

New Hampshire’s statute also contains a discovery rule: when an injury and its connection to someone’s conduct could not reasonably have been discovered at the time, the three years generally runs from when you discovered it or reasonably should have. That matters most in medical cases and slow-developing injuries — and it is fact-specific enough that you should confirm how it applies to your situation with a licensed New Hampshire attorney rather than assume. For a sense of how New Hampshire’s deadline compares nationally, see our state-by-state statute of limitations guide.

Hurt by a snowplow, a school van, or on public property? Read this twice

Claims against government entities are where New Hampshire’s otherwise-comfortable timeline collapses. Two different regimes apply, and both are stricter than the ordinary rules:

• Towns, cities, and other local units (RSA 507-B). The statute calls for notifying the governmental unit’s clerk by registered mail within 60 days of the injury. Courts may excuse imperfect notice where the town was not prejudiced, but that is never something to count on. Liability is also capped — generally $325,000 per person and $1,000,000 per incident as of 2026.
• The State of New Hampshire (RSA 541-B). Claims against state agencies generally require written notice to the agency within 180 days, and awards are capped — generally $475,000 per claimant and $3,750,000 per incident, with no punitive damages.

In a state where winter road maintenance, municipal plows, and town-owned sidewalks generate a steady share of injuries, these short windows catch people constantly. If any public entity might be involved — even indirectly — treat the deadline as measured in weeks, not years.

Damage caps: mostly none, with one recently raised exception

New Hampshire has no general cap on compensatory damages in personal injury cases, and its Supreme Court has struck down past attempts to cap damages in medical injury cases — so, as of 2026, there is generally no medical malpractice cap either. The notable exception is wrongful death: under RSA 556:12, damages for a surviving spouse’s loss of comfort, society, and companionship are capped at $500,000, and loss-of-familial-relationship damages between parents and children are capped at $300,000 per claimant. Those figures are themselves recent news — lawmakers raised them substantially in a 2024 amendment effective January 1, 2025, a meaningful change for New Hampshire families.

What to do with all of this

The short version: confirm what insurance actually exists on both sides early, do not accept an adjuster’s fault math as final, calendar the three-year deadline the day you are hurt, and move immediately if a town or state agency is anywhere in the picture. For the condensed numbers, our New Hampshire quick-reference page puts the key deadlines and rules in one place. And because every rule above has exceptions, treat this as orientation, not legal advice — confirm the specifics with a licensed New Hampshire attorney.
