ATV Accidents Involving Children in Louisiana: Special Rules and Hidden Risks

The parents were inside the house off Prien Lake Road. The neighbor's 12-year-old was outside showing their 9-year-old son how to ride the family's full-size 450cc ATV. Nobody thought much of it. Twenty minutes later, Lake Charles Memorial Hospital had two patients: a broken wrist and a fractured pelvis, both children, both hurt when the machine accelerated unexpectedly on a slope and rolled.

ATV crashes involving children sit in their own legal category in Louisiana. Louisiana Civil Code Article 2318 makes parents liable for the negligent acts of their minor children. Louisiana Revised Statutes 32:297.1 and the federal ATV industry guidelines embedded in Louisiana regulatory practice set age and machine-size restrictions for child riders. And the comparative fault analysis under CC Art. 2323 applies differently to children than to adults. Parents who find themselves dealing with an injured child after an ATV crash need to understand all three of these layers before speaking to any insurance company.

Louisiana Age Restrictions and Machine-Size Guidelines

Louisiana Revised Statutes 32:297.1 addresses ATV operation on public roads and incorporates age-related restrictions that courts and juries treat as the baseline standard of care for off-road riding as well.

The ATV industry guidelines, which federal and state agencies have adopted as safety standards, break down like this: children under 6 should not ride any ATV. Children 6 through 11 should use only youth-model machines rated for their age and weight, typically with engines under 70cc. Children 12 through 15 should use machines under 90cc. Adult-size ATVs, those 90cc and above, are not designed for children under 16.

These are not just suggestions. When an adult puts a 10-year-old on a full-size 450cc ATV and the child is hurt, the age and machine-size guidelines become evidence of negligence per se. The adult violated the industry standard. That violation is treated as fault.

Side-by-side UTVs present a different question. Many side-by-sides are belt-and-roll-cage machines that are arguably safer than open ATVs, and children are frequently passengers rather than operators. The seat belt use, roll cage integrity, and whether the machine was designed for passenger use all factor into a crash analysis involving a child passenger.

Adult Responsibility and Supervision

The adult who controls the activity bears primary responsibility for a child's ATV safety. That means the adult who owns the machine, the adult who gave the child permission to ride, and the adult who was present and supervising at the time of the crash.

We explain how fault percentages and deadlines work after a Louisiana injury in our 2026 Tort Reform Survival Guide.

Louisiana Civil Code Article 2315 applies in full to adults who negligently supervise children on ATVs. Louisiana Civil Code Article 2318 makes parents vicariously liable for their minor children's torts, but in ATV injury cases the child is usually the injured party, not the tortfeasor. The negligent adults are the ones who made the decisions that led to the crash.

Common adult supervision failures in child ATV cases include: leaving the child unsupervised on a machine they are unfamiliar with, allowing a child to operate a machine rated for a much larger or older rider, permitting riding on terrain too technical for the child's experience level, failing to require a helmet or other protective gear, and allowing an untrained older child to supervise a younger one.

The negligent adult does not have to be the parent. An uncle, a neighbor, a family friend, or even a business that rents ATVs can face liability for permitting a child to ride an inappropriate machine without adequate supervision.

How Comparative Fault Works Differently for Children

Louisiana courts apply a modified standard when assessing a child's comparative fault. The question is not whether the child behaved as a reasonable adult would have. The question is whether the child behaved as a reasonably prudent child of the same age, experience, and development would have.

A 7-year-old who accelerates too fast on a trail is not held to the same standard as a 17-year-old with two years of riding experience. Very young children may receive no fault assignment at all because they cannot be expected to appreciate risks that an adult would recognize.

Older teenagers, particularly those close to 18, may be held close to the adult standard. A 17-year-old who has been riding ATVs for four years and takes a machine out at high speed on wet terrain may receive a fault percentage approaching what an adult would receive for the same conduct.

The practical effect is that most ATV injury cases involving younger children result in the adult defendants absorbing the bulk of the fault. That is appropriate, because the adults made the decisions that put the child in the situation.

The Prescriptive Period for Children's Claims

One of the most important differences between child ATV injury claims and adult claims is the prescriptive deadline.

Louisiana Code of Civil Procedure Article 3492 sets a one-year prescriptive period for personal injury claims. For adults, that clock starts on the date of the crash. For minor children, the prescriptive period is tolled, meaning it does not start running, until the child reaches the age of majority at 18. A child hurt in an ATV crash at age 10 generally has until age 19 to file suit on their own injury claim.

Parents' derivative claims — for medical expenses they paid and for loss of consortium — do not enjoy the same tolling. Those claims are governed by the adult one-year period from the date of the crash. If the parents wait two years to consult a lawyer, their own claims may already be prescribed even though the child's claim remains alive.

If a government entity owns or maintains the property where the crash happened, or if a government employee was involved, notice requirements and shorter deadlines may apply. These situations require immediate legal consultation.

How Louisiana's 51% Fault Rule Applies When a Child Is Injured

The 51% bar applies to claims brought on behalf of children in the same way it applies to adult claims. If a court assigns a child plaintiff 51% or more of the total fault, the child recovers nothing.

In practice, this threshold is rarely reached for young children because of the modified standard of care applied to them. But consider a scenario with an older teenager.

A 16-year-old with riding experience borrows a friend's ATV without the owner's permission, rides at high speed on a trail the owner specifically said was off-limits, and crashes when a trail hazard that the landowner knew about causes a rollover. The teen's damages total $120,000.

The jury could reasonably find: teen 35% at fault for taking the machine without permission and speeding; ATV owner 20% at fault for failing to secure the machine; landowner 45% at fault for the dangerous trail condition. Recovery: $78,000 (65% of $120,000).

Change the facts slightly. Teen 52% at fault because the speeding was the primary cause of the crash. Recovery: zero.

Age and conduct both matter to this calculation. A responsible 14-year-old on a size-appropriate machine faces far less comparative fault risk than a reckless 17-year-old on an adult machine.

Frequently Asked Questions

Can a child's comparative fault reduce or eliminate an ATV injury claim in Louisiana?

It can in theory, but young children are held to a child-appropriate standard, not an adult one. Very young children typically receive no fault assignment at all. Older teenagers may approach the adult standard. The 51% bar applies to child claims just as to adult ones, but reaching that threshold is much harder when the child is young and the supervising adults made the decisions that created the risk.

Are parents liable if their child is injured on an ATV that a neighbor or friend let the child ride?

The adult who controlled the activity and permitted the ride is the primary target. A neighbor who let a child ride an adult-size ATV without adequate supervision faces liability under Louisiana Civil Code Article 2315. The child's parents may face questions about their own supervision decisions, but the adult who was present and in charge at the time of the crash generally bears the larger fault share.

What are Louisiana's age restrictions for ATV riding?

Louisiana incorporates ATV industry guidelines that recommend children under 6 not ride at all, children 6 to 11 use only small-engine youth models, and children 12 to 15 use machines under 90cc. Adult-size ATVs are not designed for riders under 16. Violating these guidelines is treated as evidence of negligence, and in some cases negligence per se, in Louisiana injury litigation.

How long does a family have to file an ATV injury claim on behalf of an injured child in Louisiana?

The child's personal injury claim is typically tolled until the child turns 18, giving until age 19 to file suit. Parents' own derivative claims for medical expenses and loss of consortium are subject to the adult one-year period from the date of the crash. Families often let the parent claims prescribe without realizing it. Consult a lawyer quickly regardless of the child's claim deadline.

What should parents document immediately after their child is hurt in an ATV crash?

Photograph the crash site and the ATV before anything is moved. Collect the machine owner's contact information and the make and model of the vehicle. Get the names and numbers of every witness. Seek emergency care immediately — head and spinal injuries in children may not be obvious at the scene. Document every medical visit, every symptom, and every impact on the child's daily life going forward.

Statutes, regulations, and case law also change over time. Reading this does not create an attorney-client relationship. If your child was injured in an ATV accident in Lake Charles or Calcasieu Parish, talk to a licensed Louisiana personal injury attorney as soon as you can. The one-year prescriptive period for parents' derivative claims is strictly enforced.
