The Missouri Rules That Decide Whether an Off-Road Injury or Death Claim Can Go Forward

Five Missouri statutes do most of the work in an off-highway vehicle case, and each answers a different question an injured rider or a family may be asking.

The time allowed for an injury action comes from section 516.120 of the Revised Statutes of Missouri. It provides that "within five years" a person may bring "an action for taking, detaining or injuring any goods or chattels, including actions for the recovery of specific personal property, or for any other injury to the person or rights of another, not arising on contract and not herein otherwise enumerated." A crash injury generally falls within that "any other injury to the person" language.

Section 516.170 of the Revised Statutes of Missouri addresses when filing of an action may be delayed. Except as section 516.105 provides, a person who was "within the age of twenty-one years, or mentally incapacitated" when the cause of action accrued may bring the action within the respective times the limitations sections allow "after such disability is removed."

A death is governed by section 537.080 of the Revised Statutes of Missouri, which names who may sue, and section 537.100 of the Revised Statutes of Missouri, which requires the action to be commenced "within three years after the cause of action shall accrue."

A rider's own fault in a product case is addressed by section 537.765 of the Revised Statutes of Missouri, which applies "the doctrine of pure comparative fault" to products liability claims.

A landowner's duty to people riding on land for free is limited by section 537.346 of the Revised Statutes of Missouri, Missouri's recreational-use rule, subject to the exceptions that section names.

Put simply, these five rules set the outer edges: whether there is still time, who can bring a claim, and whether a rider's own conduct or the place of the crash narrows it.

How the Vehicle You Rode and the Way It Crashed Shape a Claim

Off-highway vehicles come in more than one kind, and the law does not treat them all alike. Under federal law, 15 U.S.C. § 2089, an all-terrain vehicle (ATV) is "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," excluding research and development prototypes not offered for sale. In plain terms, that means a straddle seat and handlebars. That section's mandatory federal standard applies to ATVs as it defines them. It is not applied on this page to a utility task vehicle (UTV) or a side-by-side, which the Consumer Product Safety Commission (CPSC) counts separately as recreational off-highway vehicles (ROVs) and utility terrain vehicles (UTVs). If you were riding a side-by-side rather than a straddle-seat ATV, that difference can matter to which standards a product theory looks to.

The CPSC's 2025 Report of Deaths and Injuries Involving Off-Highway Vehicles with More than Two Wheels has a Table 4 showing each state's fatal incidents and deaths from 2020 through 2022, and its share of the 2,685 deaths counted nationally. The report cautions that these counts are "not adjusted for state-level demographic characteristics (i.e., total population, age distribution)," that they "reflect the state and year in which the incident occurred," and that CPSC received "limited or no death certificate data from a handful of states." The figure is a count of reported deaths, not a finding about any company, vehicle or rider. More federal data is on the site's ATV accident statistics page.

Nationally, the same report lists overturns and collisions with another vehicle or a stationary object, such as a tree, as the most common fatality hazards, and notes that occupants were frequently ejected. In Missouri, as elsewhere, the crashes that lead to claims include a rollover (the vehicle tipping onto its side or roof), an ejection, a fire, a collision on a trail, an injury to a passenger, and an injury to a child.

The kind of crash shapes which legal theory may fit. A rollover or a crash is not, by itself, proof of a product defect. A product liability theory asks whether the vehicle or a part was defective and whether that defect caused the injury. A premises theory asks about the land and the duty its owner owed, which in Missouri runs into the recreational-use rule. A recreational negligence theory asks how another rider or operator behaved. Because the vehicle type and the crash pattern point toward one theory or another, details that go unrecorded, such as the exact model or how the vehicle came to rest, can leave that question harder to answer later. The site's UTV rollover page explains why a rollover alone does not establish a defect.

Who May Be Responsible, and What Happens to a Claim If You Were Partly at Fault

The question many injured riders and families ask first is simply "who?" The answer depends on what failed and who controlled it, and it falls into categories rather than names.

Vehicle manufacturers, distributors and sellers sit on the product side. Under section 537.765, the defendant "may plead and prove the fault of the plaintiff as an affirmative defense," and any fault chargeable to the plaintiff "shall diminish proportionately the amount awarded as compensatory damages but shall not bar recovery." For this section, "fault" is limited to six things: failing to use the product as the manufacturer reasonably anticipated; using it for a purpose the manufacturer did not intend; using it with knowledge of a danger, with reasonable appreciation of the consequences and voluntary, unreasonable exposure to that danger; unreasonably failing to appreciate the danger or its consequences and unreasonably exposing oneself to it; failing to take the precautions a reasonably careful user would take against dangers they would reasonably appreciate; and failing to mitigate damages. In plain words: in a product claim, only those six kinds of conduct count against a rider, and when they do, they reduce the award by the rider's share rather than ending the claim.

Other riders, drivers, and event or trail operators sit on the negligence side. A negligence claim asks whether a person owed a duty of care, breached it, and caused injury and damages as a result.

Landowners are treated distinctly. For riding on someone else's land without paying, section 537.346 generally limits what that owner owed: except as sections 537.345 to 537.348 and section 537.351 provide, "an owner of land owes no duty of care to any person who enters on the land without charge to keep his or her land safe for recreational use or to give any general or specific warning with respect to any natural or artificial condition, structure, or personal property thereon." A second subsection bars an owner's liability for injuries to a trespasser on the owner's residential area or noncovered land, as section 537.348 defines those terms, when that land is adjacent to a park or trail and the trespasser came from it. Whether an exception applies, such as one tied to a charge for entry, depends on the text of those other sections in Missouri's current law. In plain words: a free ride on private land generally narrows what the owner can be held to, and whether any money changed hands is one of the facts that can matter.

Whether any of these standards is met is a question of the facts. An injury does not prove that anyone was at fault.

Filing Deadlines Under Missouri Law and How They Apply to Injured Riders, Children and Families

A Missouri deadline is not a technicality. If an action is not brought within the period the statute allows, the claim can end there, however strong it might otherwise have been.

For a person who was injured and survived, section 516.120's five-year period is the general starting point. That section sets the length of the period; when it begins to run turns on Missouri's accrual rules as its current law states them.

For a family after a death, section 537.100 sets three years after the cause of action accrues, with two provisos. First, if a defendant is absent from or departs Missouri so that personal service cannot be had on them in the state, the time of that absence is not counted. Second, if an action filed in time ends in a nonsuit, an arrested judgment or a reversal on appeal, the plaintiff may commence a new action within one year afterward. Separately, service on a defendant made after the limitation period has expired, or after any extension, must be made within one hundred eighty days of filing the petition, or the court shall dismiss the action against that defendant. That dismissal is without prejudice unless the plaintiff previously took or suffered a nonsuit, in which case it is with prejudice.

For a child, section 516.170 means that a person who was under twenty-one when the cause accrued may bring the action within the respective times after reaching that age, except as section 516.105 provides. The same section covers a person who was mentally incapacitated when the cause accrued.

So a single Missouri crash can involve more than one clock: one for an injured parent, another for an injured child, and a different one if someone died. Which period applies, and when it started, is a fact-by-fact question that a case evaluation request with our attorney can cover.

Records That Can Help Show What Happened on the Ride

Whatever theory fits a Missouri case, it rests on records. The records that usually matter include medical records from the first treatment onward, photos and video of the scene, the vehicle and the injuries, and the vehicle itself, because its condition can bear on whether a product theory is supported at all.

Incident and police reports, the names of witnesses and other riders, and purchase records such as a receipt or order history often help establish what was ridden, by whom and where. Maintenance and repair records matter for the same reason.

Under 15 U.S.C. § 2064, when the CPSC determines that a product presents a substantial product hazard, it may order public notice and remedies including repair, replacement or a refund. A recall notice can be relevant to a case, but a recall is not a finding that a product injured anyone, and it does not show what caused a particular crash. The federal ATV standard's role is explained on the site's CPSC ATV standard page.

In a product case, the comparative fault rule turns on how the vehicle was being used, so what the vehicle was, how it was set up and how it was ridden carry real weight. The risk is concrete: if the vehicle is repaired, sold or scrapped before anyone examines it, the evidence that could support or rule out a product theory may be lost for good. That is one reason families often raise the vehicle's whereabouts early in a conversation with an attorney.

When a Family Is Considering a Wrongful-Death Action

When a ride ends in a death, Missouri treats the family's claim as its own action, with its own rules about who may bring it and when.

Section 537.080 provides that whenever a death results from an act, conduct, occurrence, transaction or circumstance that would have entitled the person to recover damages had they lived, the party who would have been liable "shall be liable in an action for damages, notwithstanding the death of the person injured." The classes who may sue include, first, "the spouse or children or the surviving lineal descendants of any deceased children, natural or adopted, legitimate or illegitimate, or by the father or mother of the deceased, natural or adoptive." The statute lists further classes as well. It also provides that "only one action may be brought under this section against any one defendant for the death of any one person." An annotation on the official page notes a 1991 decision, Davis v. Wilson, holding that when one person entitled to bring the action has settled, others claiming to be in the class are barred from bringing their own action. If several relatives are grieving the same person, this one-action rule means their decisions are linked, and one member's settlement can affect the others.

The action must be commenced within section 537.100's three-year period, with the provisos described above.

On damages, the official page's annotations note a 1992 Missouri Supreme Court decision, Powell v. American Motors Corp., holding that survivorship damages the decedent incurred before death, such as medical expenses and pain and suffering, are recoverable as part of a wrongful-death claim. What the law may allow depends on the facts, and the same comparative fault rule applies where the family's claim is a products liability claim.

For a family deciding whether to act, the first questions are often which class each relative belongs to and when the period began; both can be talked through with our attorney.
