Vehicles are non-living means of transport. They are most often man-made (cars, motorcycles, trains, ships, aircraft), but also non-man-made means for transport can be called vehicles, including icebergs and floating tree trunks. Vehicles may be motored by animals, e.g. a chariot, or an ox-cart. However, animals on their own, though used as means of transport, are not called vehicles. This includes humans carrying another human, for example a child or a disabled person. Movement without the help of a vehicle or an animal is called locomotion. The word itself comes from the Latin vehiculum.
Most land vehicles have wheels, see that articles for vehicles with and without wheels.
