Iowa Code chapter 321I (All-Terrain Vehicles) defines an "off-road motorcycle" as a two-wheeled motor vehicle that has a seat or saddle designed to be straddled by the operator and handlebars for steering control and that is intended by the manufacturer for use on natural terrain; the term includes a motorcycle originally titled and registered for highway use under chapter 321 that contains design features that enable operation over natural terrain. The chapter's "all-terrain vehicle" is a motorized vehicle with not less than three and not more than six nonhighway tires, but off-road motorcycles shall be considered all-terrain vehicles for the purpose of registration, and for titling if no title was previously issued under chapter 321, and an operator of an off-road motorcycle is subject to the chapter's provisions governing the operation of all-terrain vehicles. The definition's own words for the machine are "motor vehicle".

Each all-terrain vehicle used on public land, public ice, or a designated riding trail of Iowa must be currently registered, and off-road motorcycles are considered all-terrain vehicles for the purpose of registration. A person may not operate one there unless it is registered under chapter 321I or applicable federal laws, or under an approved numbering system of another state, with the evidence of registration in full force and effect; a vehicle registered in another state must also be issued an Iowa user permit. A nonresident wishing to operate an all-terrain vehicle not registered under chapter 321I on public land, public ice, or a designated riding trail must obtain a user permit from the department, issued for only one vehicle, not transferable, and valid for the calendar year or the time period specified in the permit. Registration is not required for all-terrain vehicles owned by the United States, a state, or a governmental subdivision and used for enforcement, search and rescue, or official research and studies but not for recreational or commercial purposes, for those used in accordance with section 321.234A(1)(a), or for those used exclusively as farm implements.

A person under twelve years of age may not operate an all-terrain vehicle, including an off-road motorcycle, on a designated riding area or designated riding trail or on public land or public ice unless the person is taking a prescribed education training course under the direct supervision of a certified all-terrain vehicle education instructor, or the operation is under the direct supervision of a responsible parent or guardian at least eighteen years of age who is experienced in all-terrain vehicle or off-road motorcycle operation and holds a valid driver's license. "Direct supervision" means maintaining visual and verbal contact at all times. A person twelve or older but under eighteen may not operate an all-terrain vehicle on public land, public ice, a designated riding trail, or land purchased with all-terrain vehicle registration funds without a valid education certificate in the person's possession, but an operator of an off-road motorcycle is exempt from the education instruction and certification program requirements of sections 321I.25 and 321I.26.

An operator of an off-road motorcycle is subject to chapter 321I's provisions governing the operation of all-terrain vehicles. Section 321I.10 says a person may not operate an all-terrain vehicle upon roadways or highways except as provided in section 321.234A and section 321I.10. For a registered all-terrain vehicle, section 321I.10 lists: an undivided two-lane primary highway that is not part of the interstate road system, over the most direct and accessible route between an all-terrain vehicle park or trail, an authorized secondary road, an authorized city street, or the operator's residence; state park road systems, and anywhere within a state park that a motor vehicle required to be registered under chapter 321 is authorized to operate; an unpaved secondary road; a paved, undivided two-lane secondary road over the most direct and accessible route between those same kinds of locations; a paved, undivided secondary road or segment if authorized by the county board of supervisors; and city streets a city designates. A county may prohibit operation on a secondary road or segment when it is closed to motor vehicle traffic or designated as a detour route under section 306.41, or, for any other secondary road, for no more than seven consecutive days and no more than thirty days in a calendar year when the prohibited days are established by ordinance. A direct crossing of a highway that is not part of the interstate road system must be made at an angle of approximately ninety degrees where no obstruction prevents a quick and safe crossing, after a complete stop, yielding the right-of-way to all oncoming traffic that constitutes an immediate hazard, on a divided highway only at an intersection with another public street or highway, and from and to a street, roadway, or highway on which the vehicle is authorized to operate.
