Introduction to Automobile

An automobile is a self propelled vehicle i.e. a vehicle producing power within itself for its propulsion and requires no external power such as scooter, motor cycle, car, jeep, bus, truck, tractor etc. A self propelled vehicle considered to carry passengers or goods and ply on the road surface is called an automobile.

Thus from the above examples it is clear that all vehicles are not automobiles like locomotives, ships, aeroplane and rocket etc. because automobiles run on the road surface. A train runs on the railway track not on the road surface hence train is not an automobile.
