Vehicles are non-living means of transport. They are most often man-made  bicycles, cars, motorcycles, trains, ships, boats, and aircraft, although some other means of transport which are not made by man can also be called vehicles; examples include icebergs and floating tree trunks.

Vehicles may be propelled by animals, for instance, a chariot or an ox-cart. However, animals on their own, though used as a means of transport, 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 craft, such as watercraft, sailcraft, aircraft, hovercraft and spacecraft.

Land vehicles are broadly classified by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed, and/or skied.Airbags and specialised child restraint systems have improved on that. Structural changes such as side-impact protection bars in the doors and side panels of the car mitigate the effect of impacts to the side of the vehicle. Many cars now include radar or sonar detectors mounted to the rear of the car to warn the driver if he or she is about to reverse into an obstacle or a pedestrian. Some vehicle manufacturers are producing cars with devices that also measure the proximity to obstacles and other vehicles in front of the car and are using these to apply the brakes when a collision is inevitable
