Some bus companies may like to repaint the bus with a special livery for training bus after the bus is retired from the passenger-serving fleet, which is usually white or a plainer version of the company's regular livery. Some bus companies may also remove most of the facilities (such as passenger seats) from a training bus, so that those facilities can be installed onto some newer buses. On a training bus, there is usually another seat for the driving instructor (trainer) next to the driver's seat.
