__TOC__ A training bus is usually a bus that has been retired from the passenger-serving fleet. Some bus companies may repaint the bus with a special livery to signify its roll as a 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 also usually another seat for the driving instructor (trainer) next to the driver's seat. This allows the instructor to monitor how trainee is driving and give appropriate instruction when necessary.
