Vehicles are non-living means for transportation. They are most often man-made (automobiles, locomotives, ships, aircraft), but also non-man-made means for transportations can be called vehicles, including icebergs and floating tree trunks. Animals, though used as means for transportation, are not called vehicles. This includes humans carrying another human, for example a child or a disabled person. Forms of transportation without vehicle or animal are walking, running, crawling, swimming and (for certain animals) flying.
