New Hampshire Car Accident Laws: Fault, Insurance, and Your Claim
New Hampshire Car Accident Laws: Fault, Insurance, and Your Claim
New Hampshire is an at-fault (tort) state that follows modified comparative negligence with a 51% bar, so the at-fault driver pays and your recovery is reduced by your share of fault but is barred entirely if you are found more than 50% responsible. Uniquely, New Hampshire does not require drivers to carry liability insurance.
Is New Hampshire a no-fault or at-fault state?
New Hampshire is a pure at-fault (tort) state. The driver who is legally responsible for a crash bears full liability for the resulting bodily injury and property damage. New Hampshire is not among the 12 states with mandatory no-fault or PIP systems (Florida, Michigan, Minnesota, New York, North Dakota, Hawaii, Kansas, Kentucky, Massachusetts, New Jersey, Pennsylvania, and Utah). There is no personal injury protection statute and no no-fault threshold that an injured person must clear before bringing a tort claim.
Because New Hampshire is an at-fault state, an injured accident victim files a claim directly against the at-fault driver and that driver's liability insurer. There is no verbal or monetary injury threshold to overcome before suing for pain and suffering. Any injured party may bring a negligence claim, subject to New Hampshire's modified comparative fault rule and the 3-year statute of limitations under RSA 508:4. While New Hampshire does require medical payments (MedPay) coverage in any policy that is issued (RSA 264:16), MedPay is not a no-fault system and does not bar a tort claim against the at-fault driver.
How fault is shared: New Hampshire's negligence rule
New Hampshire follows modified comparative fault with a 51% bar under RSA 507:7-d. Under this rule, an injured party's damages are reduced in proportion to their own share of fault. However, if the claimant is found to bear more than 50% of the fault for the collision, recovery is completely barred.
For example, if a jury awards $100,000 in damages but finds you 35% at fault, your net recovery is reduced to $65,000. If the jury finds you 51% or more at fault, you recover nothing. The 51% bar means that as long as you are not more than equally at fault (50% or less), you may still recover a proportionally reduced award. This rule applies in all negligence actions, including multi-vehicle crashes where the fault of every party is compared and apportioned. Because New Hampshire does not require insurance, partial-fault scenarios can raise real collection concerns if the at-fault driver is uninsured, making UM/UIM coverage especially valuable.
Minimum car insurance in New Hampshire
New Hampshire stands apart from every other state by not mandating that drivers carry liability auto insurance as a condition of registering or operating a vehicle. Instead, RSA chapter 264 imposes a post-accident financial-responsibility framework: any driver involved in an accident, conviction, or other triggering event must demonstrate the ability to "respond in damages" at the statutory minimum limits or face suspension of driving privileges and registration.
When a policy is carried or when a driver is ordered to file proof of financial responsibility (including an SR-22), the minimum limits are 25/50/25 under RSA 264:20: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage. These figures describe the minimum that must be shown once coverage is required or purchased; they are not a universal carry mandate.
Every auto policy that IS issued in New Hampshire must include two additional protections. Under RSA 264:15, no policy may be delivered without uninsured/underinsured motorist (UM/UIM) coverage at limits at least equal to the policy's bodily-injury liability limits (minimum 25/50). A named insured may reject only UM/UIM above the minimum in writing; coverage at 25/50 is non-waivable once a policy exists. Under RSA 264:16, any issued policy must also include at least $1,000 in medical payments (MedPay) coverage per person, which the insured may reject in writing. Because insurance is optional and a significant share of NH drivers choose to go without, these UM/UIM and MedPay protections are particularly important for anyone who does choose to carry a policy.
How long you have to file: the statute of limitations
New Hampshire gives car accident victims 3 years to file a personal-injury or property-damage lawsuit from the date of the crash. This deadline is set by RSA 508:4, which establishes a 3-year limitations period for all personal actions, including negligence claims arising from auto accidents. There is no shorter special limitation period for motor-vehicle tort claims; the same 3-year window applies to both bodily injury and property damage.
A discovery-rule exception can toll the clock in some cases, delaying the start of the limitations period until the plaintiff discovers, or reasonably should have discovered, both the injury and its causal connection to the defendant's conduct. This exception is most relevant in cases involving latent injuries that are not immediately apparent after the collision. Regardless of whether the discovery rule applies, waiting to consult an attorney increases the risk of losing evidence, missing witnesses, and running out of time.

What a New Hampshire car accident claim is worth
The value of a New Hampshire car accident claim depends on your economic damages, your non-economic damages, and any reduction from the fault assigned to you under the modified comparative negligence rule. Economic damages include all verifiable monetary losses: emergency medical care, surgery, rehabilitation, future medical costs, lost wages, lost earning capacity, and vehicle repair or replacement. Non-economic damages cover pain and suffering, emotional distress, loss of enjoyment of life, and permanent scarring or disability.
Because New Hampshire does not mandate insurance, the practical value of a claim is directly tied to the at-fault driver's financial position. A driver who chose to go uninsured remains personally liable, but collecting a judgment against an uninsured individual is often difficult. Your own UM/UIM coverage (mandatory in any policy you carry) is frequently the most reliable source of recovery when the at-fault driver is uninsured or underinsured. For insured defendants, the 25/50/25 statutory minimums are relatively modest; serious injuries can quickly exceed those caps, again placing the burden on your own UM/UIM and MedPay policies.

What to do after a car accident in New Hampshire
The steps you take immediately after a New Hampshire car accident can directly affect the strength of your claim.
Stay safe and call for help. Move to a safe location if you can do so without aggravating injuries. Call 911 if anyone is hurt, if property damage is significant, or if a driver appears impaired. New Hampshire law requires drivers to stop, render aid, and exchange information after any collision involving injury or damage.
Document the scene. Photograph all vehicles from multiple angles, road and weather conditions, traffic controls, skid marks, debris fields, and any visible injuries. Collect the name, contact information, driver's license number, and any insurance information (if they have it) from every driver involved. Get contact information from witnesses before they leave.
Identify whether the other driver carries insurance. Because New Hampshire does not require insurance, confirming whether the at-fault driver has a policy is critical. If they are uninsured, your own UM/UIM coverage may be your primary recovery source.
Seek medical attention promptly. See a doctor as soon as possible even if you feel fine initially. Concussions, whiplash, and soft-tissue injuries often present symptoms hours or days after impact. A timely medical record is essential for connecting your injuries to the crash and for calculating your damages.
Preserve evidence and notify your insurer. Report the accident to your own insurer promptly and accurately. Keep all medical bills, repair estimates, and records of time missed from work. Photograph injuries over time to document their progression.
Consult an attorney before accepting any settlement. Insurance adjusters serve the insurer's interests, not yours. A New Hampshire personal-injury attorney can evaluate the full scope of your damages, advise you on comparative-fault exposure under the 51% bar, and negotiate before you sign any release. Most work on a contingency-fee basis, so there is no upfront cost.
