Is New Hampshire a no-fault or at-fault state?

New Hampshire is an at-fault state. Whoever causes a crash is responsible for the harm, and that driver's insurance (or the driver personally) pays for it. There's no personal injury protection system routing your own medical bills through your own policy first, and no short election deadline like the 14-day rule Florida drivers deal with. After a crash here, you pursue the at-fault driver's liability coverage, lean on parts of your own policy, or both.

That short answer comes with a wrinkle that sets New Hampshire apart from every other state, so the details matter.

New Hampshire doesn't make you buy insurance

New Hampshire is the only state that doesn't require most drivers to carry auto liability insurance.¹ Instead of a purchase mandate, it runs a financial responsibility law under RSA chapter 264. You have to be able to pay for the damage you cause, and you can prove that by carrying insurance, posting a bond, or making a cash deposit with the state.¹²

The test comes after the fact. Cause a crash, fail to show proof of financial responsibility, and the DMV can suspend your license and registration until you file proof and cover the harm you did.¹² Driving uninsured is legal right up until you hurt someone, and then it gets expensive fast.

Most people do carry a policy, and state law sets the floor. Minimum liability limits are $25,000 for injury to one person, $50,000 per crash when two or more people are hurt, and $25,000 for property damage, usually written as 25/50/25.²³ That's what a bare-bones policy carries, and it runs out quickly against a serious injury.

How fault gets divided

Since fault decides who pays, a lot of the fight after a New Hampshire crash is about percentages. The state uses modified comparative negligence with a 51% bar.⁴

RSA 507:7-d says your own fault won't block your recovery as long as it "was not greater than the fault of the defendant."⁴ Put simply, at 50% fault or less you can still recover; at 51% or more you recover nothing. When you do recover, the award "shall be diminished in proportion to the amount of fault attributed to" you.⁴

Here's how that plays out. Suppose your damages total $100,000 and the adjuster or a jury decides you were 20% responsible. You collect $80,000. Nudge your share to 51%, and you collect zero. That gap is why insurers work to pin a piece of the blame on you, and why the percentage is worth contesting.

Where New Hampshire borrows from no-fault

New Hampshire isn't a no-fault state, but one part of your own policy behaves a little like it. Every private passenger auto policy issued or renewed in the state must include at least $1,000 per person in medical payments coverage.⁵ Med pay covers reasonable medical costs for you and your passengers regardless of who caused the crash, as long as the costs are incurred within three years of the injury.⁵

Two features make it worth understanding. It pays no matter who was at fault, so your first bills can be handled before the liability question is settled. And it's non-subrogable: under RSA 264:17, your insurer can't claw that money back out of a later settlement.⁶ The $1,000 minimum is low, so many drivers buy more, but even the floor gives you money that moves quickly.

This is also where the Florida comparison breaks down. New Hampshire has no PIP and no election deadline. Nothing forces you to file within 14 days to keep benefits. The three-year window on med pay tracks when costs are incurred, not a report-it-or-lose-it clock.⁵

Uninsured and underinsured drivers

A state with no insurance mandate has an obvious side effect: some of the cars around you carry nothing, and plenty carry only the 25/50/25 minimum. That makes uninsured and underinsured motorist coverage (UM/UIM) important here.

New Hampshire builds it in. When you buy liability coverage above the state minimum, your UM/UIM coverage automatically equals your liability limits.⁷ You can reject it, but only in writing, and a named insured's written rejection applies to every insured and every vehicle on the policy until someone requests the coverage back in writing.⁷ If the driver who hit you had no insurance or too little, this is often the coverage that actually pays.

What you can and can't recover

New Hampshire doesn't cap damages in an ordinary car crash case. There's no ceiling on medical bills, lost income, or pain and suffering. The state once had a statutory cap on noneconomic damages, but the New Hampshire Supreme Court struck it down as unconstitutional in Carson v. Maurer in 1980, and the legislature never replaced it.⁸

Punitive damages are the exception. Under RSA 507:16, "no punitive damages shall be awarded in any action, unless otherwise provided by statute."⁹ Even against a reckless or drunk driver, you can't add punitive damages as a separate category unless a specific statute allows it, and none does for a standard crash.⁹

Drunk driving cases do open one extra path. New Hampshire's dram shop law, RSA chapter 507-F, lets a crash victim sue a bar, restaurant, or server that negligently or recklessly served alcohol to a minor or to someone already visibly intoxicated.¹⁰ That's a claim against the server's insurance on top of your claim against the driver, though it doesn't lift the punitive-damages bar.⁹¹⁰

Deadlines you can't miss

The main clock is three years. RSA 508:4 gives you three years from the crash, or from when you reasonably discover the injury, to file suit for personal injury or property damage.¹¹ Miss it and the court will almost certainly dismiss the case no matter how strong it is.

There's a separate, shorter reporting duty. If your crash injured someone or caused more than $1,000 in property damage and no police officer investigated it, you have to file a written report with the DMV within 15 days.¹² A police-investigated crash satisfies that requirement, so the officer's report covers you.¹² That report is not your insurance claim, but skipping it can cost you your license.

What this means for your claim

Everything here ties back to fault. The practical work after a New Hampshire crash is proving the other driver caused it and documenting what it cost you, because the fault percentage sets the size of your recovery. The other driver may carry no insurance at all, which is where your own med pay and UM/UIM coverage step in. When injuries are serious or fault is contested, getting advice early protects the claim well before the three-year deadline closes in. You can find a New Hampshire attorney when you're ready.
