Vehicles are non-living means of transportation. They are most often man-made (e.g. bicycles, cars, motorcycles, trains, ships, and aircraft), although some other means of transportation which are not made by man can also be called vehicles; examples include icebergs and floating tree trunks.
Vehicles may be propelled by animals, e.g. a chariot or an ox-cart. However, animals on their own, though used as a means of transportation, are not called vehicles. This includes humans carrying another human, for example a child or a disabled person.
Vehicles that do not travel on land are often called crafts, such as watercraft, sailcraft, aircraft, hovercraft and spacecraft
Most land vehicles have wheels. Please see the wheel article for examples of vehicles with and without wheels.
Movement without the help of a vehicle or an animal is called locomotion. The word vehicle itself comes from the Latin vehiculum.
