Which New Hampshire Rules Apply Depends on What Happened to You

If you are trying to understand where a claim might stand, the starting point is that New Hampshire uses its own Revised Statutes Annotated for most off-highway vehicle injuries, with its own rules on time limits, fault and damages. Three kinds of claim tend to come up, and each has its own statute, so the kind of claim shapes which deadline and which defenses matter to you. The first is ordinary negligence, meaning a failure to use reasonable care, such as by another rider or an operator. The second is a premises claim against a landowner, which New Hampshire's recreational-use law limits sharply in some situations. The third is product liability, meaning a claim that a vehicle or component was defective, which has its own time limits.

Which of these fits depends on what happened, not on the type of vehicle alone. A useful early question is who was driving, whose land it was and whether any part seemed to fail, since those answers point toward one theory or more.

Some context comes from the U.S. Consumer Product Safety Commission. In Table 4 of its 2025 Report of Deaths and Injuries Involving Off-Highway Vehicles with More than Two Wheels, CPSC lists the total number of fatal incidents and total deaths due to off-highway vehicle incidents attributed to each state for 2020 through 2022, with California, Pennsylvania, Georgia, Kentucky and West Virginia reporting the most deaths. The report says its state counts are "not adjusted for state-level demographic characteristics (i.e., total population, age distribution)" and "reflect the state and year in which the incident occurred." It also notes that CPSC received "limited or no death certificate data from a handful of states." The figure says nothing about any company, vehicle or rider. Broader national figures appear on our page of ATV accident statistics.

Among the New Hampshire statutes this page discusses, the only dollar limits on damages appear in the wrongful-death statute covered below. None of them sets a general cap on personal-injury damages.

How the Type of Crash You Were In Shapes the Legal Questions

The crash itself usually points toward the legal questions that follow. A rollover is a crash in which the vehicle tips onto its side or roof. An ejection is when a rider or passenger is thrown from the vehicle. A fire is a vehicle burning during or after use. A collision is a crash into another vehicle, a tree or another fixed object. CPSC's report states that overturns and collisions were the most common hazards in reported off-highway vehicle deaths, and that occupants were frequently ejected in those incidents.

A crash does not, by itself, mean a product was defective. A rollover on a steep trail may raise questions about how someone drove, how land was kept, or how a vehicle performed, and each is answered on the facts. For you, that means the details of the crash, not the label on it, decide which claims are worth looking at.

Vehicle type matters too. If the machine was an ATV, a federal definition and safety standard may come into the picture. 15 U.S.C. § 2089 defines an all-terrain vehicle (ATV) as "any motorized, off-highway vehicle designed to travel on 3 or 4 wheels, having a seat designed to be straddled by the operator and handlebars for steering control," and the federal ATV safety standard in 16 C.F.R. part 1420 applies to ATVs as that text defines them. If the vehicle was a utility task vehicle (UTV) or side-by-side, with seats placed next to each other, it falls outside that definition as written, so state law comes first. Noting the make, model and seating layout early helps sort out which rules apply. Our page on UTV rollover claims covers that vehicle class more broadly.

Who May Be Responsible for Your Injury in New Hampshire

If you are trying to work out who, if anyone, is responsible, the answer usually depends on who controlled the vehicle, the land and the design. Each possible defendant is held to a different legal question.

Another rider or driver may face a negligence claim, which asks whether that person failed to use reasonable care and whether that failure caused the injury. A landowner who allowed riding may be protected by section 508:14 of the New Hampshire Revised Statutes Annotated, covered in the next section. A manufacturer or seller may face a product liability claim, which asks whether the vehicle had a defect and whether the defect caused the harm. A rental operator may raise more than one of these questions, depending on what the operator controlled. No company is presumed responsible because its vehicle or its land was involved.

A town, the state or another governmental unit has a separate rule. Under section 507-B:7 of the New Hampshire Revised Statutes Annotated, "as a condition precedent to commencement of the action, the clerk of the governmental unit shall be notified by registered mail within 60 days after the time of the injury or damage" and "as to the date, time and location where the injury or damage occurred." If the injury could not reasonably have been discovered when it happened, the 60 days run from discovery instead. Where the governmental unit claims it lacked written notice, actual knowledge or a reasonable chance to learn of the injury within 60 days, it carries the burden of proving that it was substantially prejudiced. The same section generally requires the action itself to begin within 3 years after the injury, with the same discovery rule.

Because this notice comes so early, a question worth asking right away is whether the crash happened on public land, a public trail or a road a town maintains. A conversation with an attorney can help identify each possible party and which rule each one raises.

When the Crash Happened on Someone Else's Land: New Hampshire's Recreational-Use Protection

Much New Hampshire riding happens on land someone else owns, which makes section 508:14 of the New Hampshire Revised Statutes Annotated central to many claims. This recreational-use protection limits a landowner's liability in specific circumstances.

Under paragraph I, an owner, occupant or lessee of land, including the state or any political subdivision, "who without charge permits any person to use land for recreational purposes or as a spectator of recreational activity, shall not be liable for personal injury or property damage in the absence of intentionally caused injury or damage." Two conditions matter: the use was permitted, and it was without charge. Paragraph IV says a voluntary contribution or other payment not required for using the land is not a charge. A lease of land for these purposes to the state, a political subdivision or a nonprofit corporation, trust or association is not a charge either. "Land" includes railroad property and rights-of-way.

Paragraph II is separate. A person, corporation or nonprofit entity that builds, maintains or improves trails for public recreational use, and anyone performing services for a nonprofit entity, is not liable "in the absence of gross negligence or willful or wanton misconduct."

For a rider hurt on private land open to trail use, the questions often become whether a fee was required, who owned or maintained the trail, and what conduct is alleged. Whether the protection applies depends on those facts.

Filing Deadlines and Fault Rules Under New Hampshire Law

Two questions often come first for injured riders: what the time limit is, and whether their own role in the crash ends the claim. New Hampshire answers both in its statutes.

Section 508:4 of the New Hampshire Revised Statutes Annotated provides that, "except as otherwise provided by law," personal actions "may be brought only within 3 years of the act or omission complained of." When the injury and its link to the act "were not discovered and could not reasonably have been discovered" at the time, the action must begin within 3 years of when the plaintiff discovers, or with reasonable diligence should have discovered, both the injury and that link. Other statutes can set different periods, such as the product rule and the governmental-unit rule on this page.

Children have their own rule. Chapter 508, in section 508:8 of the New Hampshire Revised Statutes Annotated, states that "an infant or mentally incompetent person may bring a personal action within 2 years after such disability is removed."

Comparative fault means a rider's own share of blame is weighed against the defendant's. Under section 507:7-d of the New Hampshire Revised Statutes Annotated, contributory fault does not bar recovery for death, personal injury or property damage "if such fault was not greater than the fault of the defendant, or the defendants in the aggregate if recovery is allowed against more than one defendant." Damages are then "diminished in proportion to the amount of fault attributed to the plaintiff." The party claiming fault carries the burden of proving it.

If you think you may share some blame, that alone does not end a claim; speed, a passenger's choices or riding conditions become part of the weighing. Writing down the crash date, when the injury was first diagnosed, and the injured person's age helps show which time rule may apply, and an attorney can help sort out how these rules fit together.

When a Vehicle or Part May Have Failed: Product Liability Under NH Law

If you believe a brake, steering part, restraint or door failed, a product liability claim may come into view. It asks two things: whether the product had a defect, and whether the defect caused the injury. A crash alone shows neither, so what is at stake is proof about the vehicle itself. For federal reporting purposes, CPSC's definition in 16 C.F.R. § 1115.4 describes a defect as "a fault, flaw, or irregularity that causes weakness, failure, or inadequacy in form or function," which can come from how a vehicle was manufactured, how it was designed, or its warnings and instructions. The federal ATV standard applies only to ATVs, as our page on the CPSC ATV safety standard explains.

New Hampshire sets its own time limits in section 507-D:2 of the New Hampshire Revised Statutes Annotated. Product liability actions must begin within 3 years of when the plaintiff discovered the injury, or should have with reasonable diligence. They must also begin no later than 12 years after the manufacturer of the final product "parted with its possession and control or sold it, whichever occurred last." For a lessor, bailor or licensor with a legal duty to inspect or maintain the product, the 12 years run from when that control or duty ends. A claim based on a later regulatory duty to recall, repair or warn has 6 years from when that duty arose, without shortening the other periods. These limits do not apply to actions based on fraudulent misrepresentation, concealment or nondisclosure, or to a written contract setting a different period, among other listed exceptions.

The 12-year limit can bar a claim about an older vehicle even when the injury is recent. That makes the vehicle's age, purchase history and the failed part itself worth keeping track of, and these are details an attorney can review.

Evidence That Often Matters in New Hampshire Off-Highway Vehicle Cases

Each legal question above turns on proof, and much of it may already be in a family's hands. What is at stake is simple: records that go missing can make a theory harder to support later. The records that usually matter include medical records, which show injuries and treatment. Photos and video of the scene, the trail and the vehicle can show conditions and damage. The vehicle itself, and any failed part, often sits at the center of a defect question. Purchase receipts, rental agreements or order history help identify the model and who sold or supplied it. Incident and police reports, and witnesses' names, record what others saw.

Different evidence matters for different theories. A negligence claim against another rider rests on how the crash unfolded. A landowner question under section 508:14 can turn on whether a fee was charged and who maintained a trail, so permits, signs or payment records may become relevant. A product claim depends on the vehicle's condition and age.

Sorting out which records connect to which theory is often where people feel stuck. A conversation with our attorney can cover what was kept and how it relates to New Hampshire's rules; you may want to consider requesting a case evaluation when you are ready.

When a Family Loses Someone: Wrongful-Death Claims Under New Hampshire Law

For a family grieving someone lost in a crash, the legal side can feel like the last thing to face, yet New Hampshire's statute frames it in a particular way. Under section 556:12 of the New Hampshire Revised Statutes Annotated, the action is brought by the administrator of the deceased party, the person appointed to handle the estate.

When the death was caused by the injury complained of, the law may consider the mental and physical pain the person suffered, the reasonable expenses to the estate, the probable length of life but for the injury, and the capacity to earn money during the person's probable working life. These are weighed "in the same manner as if the deceased had survived."

The section also allows two kinds of family damages, each with a dollar limit. A surviving spouse may be awarded damages for loss of comfort, society and companionship, which "in no event" may exceed $500,000. Minor children of a deceased parent, or the parents of a deceased minor child, may be awarded damages for loss of familial relationship, including loss of comfort, society, affection, guidance and companionship. These may not exceed $300,000 per individual claimant. In both, fault by the decedent or the claimant reduces damages as section 507:7-d provides.

Because the administrator brings the action, one early question for a family is who has been, or will be, appointed to handle the estate. Records of the person's medical care, expenses and work history connect to the elements the statute lists, and an attorney can help a family see which of them apply.
