Combination bus

A combination bus, also called a truck bus or shift bus, is a purpose-built truck with a "passenger container" fulfilling the role of a bus. Such vehicles used to be common in developing countries. Alternative combination buses can be a passenger/cargo module/container mounted on a truck chassis, or a bus with a large open or closed in cargo area known as a bruck.

Truck buses have been mainly used by the military, the police anti-riot units, public utilities, as school buses, and by state owned companies on short routes for employees.
