A bill for an act relating to operating all-terrain vehicles on highways, and making penalties applicable.

This bill modifies Iowa's rules for operating all-terrain vehicles (ATVs) on highways. It creates specific exceptions allowing ATVs for agricultural use (e.g., traveling between fields or stopping for fuel) and establishes detailed rules for safely crossing highways. Registered ATVs may operate on certain undivided primary/secondary roads and city streets under local designation, but must not exceed 35 mph and are prohibited on most highways unless meeting these exceptions. The bill directly affects ATV operators, farmers, counties, and cities responsible for road designations and enforcement.
