Bus

A bus (or omnibus or autobus) is a road vehicle designed to carry passengers. A bus can generally seat a maximum of anywhere from 8 to 300 passengers.^[1] Buses are the most widely used form of public transportation,^{[citation needed]} although they are also used in tourism and as private transport.

The most common type of bus is the single-decker bus, with larger loads carried by double-decker buses and articulated buses, and smaller loads carried by midibuses and minibuses. A more luxurious version of the bus is the coach. Buses are usually powered by a diesel engine, although early buses were horse drawn and there were experiments with steam propulsion. Trolleybuses use power drawn from overhead power lines. In common with the car industry bus manufacturing is increasingly a globalised activity, with the same design of bus appearing on roads around the world.
