This legislation allows farmers who are 16 years of age or older to drive all terrain vehicles and personal transportation vehicles (i.e., motorized vehicles with three or more wheels that can travel up to 20 miles per hour) on public roads to transport agricultural products, livestock, farm machinery or supplies to or from a farm. They may also be used on public roads to transport farmers who are 16 years old or older from their residence to the farm where they work. Cities may prohibit or limit the use of such vehicles on public roads within the city if it is determined that the use of the vehicles endangers the safety of the traveling public, however counties do not have the ability to limit use in unincorporated areas.
