A small two- or four-wheeled vehicle that is normally pushed or pulled by a person and used to carry cargo. A true cart is an open-topped two-wheeled vehicle for carrying loads that is pulled by humans or animals, but over time the term "cart" has evolved to refer to a variety of small wheeled vehicles that are pushed or pulled. See wagon or carriage for larger four-wheeled vehicles pulled by an animal. For the small motor vehicle, see go-kart.
