A vehicle used primarily as a farm implement is classified as a __________.

A vehicle that is primarily used as a farm implement fulfills the definition of an "implement of husbandry." This classification is specifically designed for vehicles that are used in farming practices, such as tractors and certain types of agricultural equipment, which are integral to the operation of a farm. These vehicles are not primarily intended for transporting passengers or goods in the same way that commercial vehicles or light trucks would be.

The term "implement of husbandry" recognizes the unique role these vehicles play in the agricultural sector, focusing on their use in farming instead of their design or specifications, making this classification distinct from passenger cars and commercial vehicles which serve entirely different purposes.
