What Kind of Crash Was It, and Which Ohio Rules Could Fit It?
Whether your machine counts as an ATV can matter, because a federal safety standard applies only to vehicles that fit its definition. Under 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." Utility task vehicles (UTVs) and side-by-sides are other off-highway vehicles, which the CPSC report counts separately, and that federal ATV standard does not apply to them. The site's page on the CPSC ATV safety standard covers it in depth.
The accidents that bring people to this page include a rollover (the vehicle tipping onto its side or roof), an ejection (a rider thrown from the vehicle), a fire, a collision on a trail or with a tree, a crash on private land and a crash involving a child. The CPSC report states that overturns and collisions were the most common hazards in reported OHV deaths, and that occupants "were frequently ejected."
Three legal theories can fit these facts, and they are kept separate. Negligence asks whether someone failed to use reasonable care. Product liability asks whether a defect in the vehicle or a part caused the injury. A premises theory asks what a landowner owed. A rollover is not proof of a defect, and a crash on someone's land is not automatically a premises claim.
For land, section 1533.181 of the Ohio Revised Code (effective September 29, 1995) provides that an owner, lessee or occupant of premises owes no duty to a recreational user "to keep the premises safe for entry or use," extends no assurance of safety by giving permission, and does not assume liability for injury caused by a recreational user's own acts. It applies to privately owned, nonresidential premises, whether or not they are kept open for public use.
Each theory points to a different party, so the theory that fits shapes who, if anyone, a claim can be brought against. The type of vehicle, what happened mechanically and whose land it was are the details an attorney would usually ask about first.
