A “special truck” means a motor truck or truck tractor not used for hire with a gross weight registration of 6 through 32 ton used by a person engaged in farming to transport commodities produced only by the owner, or to transport commodities purchased by the owner for use in owners own farming operation or occasional use for charitable purposes. A special truck may be registered in the name of an individual, joint ownership, or any business or corporate name, providing the truck is used in the manner provided by law
Special truck also means a motor truck or truck tractor not used for hire with a gross weight registration of six through thirty-two ton used by a person engaged in farming who assists another person engaged in farming through an exchange of services.
A special truck does not include a truck tractor operated more than 15,000 miles annually. For truck tractors registered as special trucks for 6 through 27 ton, the owner is required to give the county treasurer a self-certification that the vehicle is not operated more than 15,000 miles a year. With this self-certification, the county treasurer shall check the appropriate document type in the VRT system. For truck tractors registered as special trucks with tonnage of 28 through 32 ton, the federal heavy vehicle use tax exemption will be accepted as evidence that the vehicle is not operated more than 15,000 miles a year. Trucks registered as special trucks are not required to be registered for combined gross weight, but truck tractors registered as special trucks are required to be registered for combined gross weight of the combination of vehicles.
