What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
This bill provides that a vehicle with out-of-state registration that meets this state’s definition of an all-terrain vehicle (ATV) or utility terrain vehicle (UTV) is an ATV or UTV, regardless of the vehicle type specified on the out-of-state registration, and is subject to legal requirements applicable to ATVs and UTVs. A vehicle with out-of-state registration that does not meet this state’s definition of an ATV or UTV is not an ATV or UTV and is not eligible for public operation on ATV trails or routes as an ATV or UTV.
The bill modifies the definition of “public all-terrain vehicle corridor” to include ATV routes and “hybrid trails,” which are combination ATV routes and trails. The bill also modifies the definition of “vehicle,” as that term is defined for purposes related to motor vehicle regulation, to provide that a UTV is not a vehicle, “except for purposes made specifically applicable by statute.”
