A minibus , microbus , or minicoach is a passenger carrying motor vehicle that is designed to carry more people than a multi-purpose vehicle or minivan , but fewer people than a full-size bus. In the United Kingdom , the word “minibus” is used to describe any full-sized passenger carrying van. Minibuses have a seating capacity of between 8 and 30 seats. Larger minibuses may be called midibuses. Minibuses are typically front-engined step-entrance vehicles , although low floor minibuses do exist.
