An off-highway vehicle is a motorized vehicle operated primarily off highways and built primarily for recreational non-highway all-terrain travel. The definition names motorcycles and dirt bikes, and covers any land transport powered by something other than muscle or wind, so an electric motor is included.

An off-highway vehicle designed primarily for travel over unimproved terrain, and under the statute's unladen-weight limit, needs a resident or nonresident OHV user indicia from the Arizona Department of Transportation to be operated in the state. It is valid for one year from issue and can be renewed. Exemptions are listed in § 28-1178.

Anyone under 18 operating or riding as a passenger on an off-highway vehicle on public or state land must wear a properly fitted and fastened helmet designed for motorized vehicle use with at least a US DOT safety rating. Allowing a minor to ride without one is also an offense.

The operating rules in § 28-1174 (ride only on open roads, trails, routes and areas, never recklessly, and without off-route damage) bind anyone who lets a minor under 12 ride. If a minor under 12 breaks them, the citation is issued to the parent or legal guardian, not the child. The section sets no minimum age.

An off-highway vehicle can be registered for highway use only if it meets every equipment requirement for highway operation in Title 28, chapter 3, article 16. The owner can ask for that registration when paying for the resident user indicia.

This page restates state law in plain words and links the text it came from. It is not legal advice. Cities, counties and the agencies that manage federal land (the Bureau of Land Management and the Forest Service) add rules of their own, so check with whoever manages the ground you plan to ride.
For a young rider, the before-you-ride checker puts the helmet and age rules first.
Statutes change. Each answer carries the date it was checked; the page is re-checked at least every 180 days and says "Review due" if that slips.
