Plain-language change summary

The amendments to Assembly Bill 221 clarify how out-of-state vehicles can be classified as all-terrain vehicles (ATVs) or utility terrain vehicles (UTVs) in Wisconsin. Previously, the classification relied on the vehicle's manufacturer certificate; now, it's based solely on whether the vehicle meets Wisconsin's definitions. This change ensures consistency in regulation and helps prevent vehicles that don't meet safety standards from being used on public trails. This matters because it aims to enhance safety and accessibility for all ATV and UTV users in the state.

Analysis by the Legislative Reference Bureau 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.
