Answer:
A vehicle is an independent conveyance for moving people or materials from one place to another. (The term does not apply to devices which themselves remain in one place : ski-lifts, conveyors, escalators, moving sidewalks.)

The general application is to wheeled vehicles or similar devices, e.g. bikes, cars, boats, trains, and less frequently planes. (NASA refers to its spacecraft as vehicles.)
