A bus is a large wheeled vehicle meant to carry many passengers along with the driver. It is larger than a car. The name is a shortened version of omnibus, which means "for everyone" in Latin. Buses used to be called omnibuses, but people now simply call them "buses".
Buses are an important part of public transport in places all over the world. Many people who do not have cars, especially the third world countries, use buses to get around. Buses make it easy for them to get to where they want to go.
There are many types of bus around the world.
