The Bus driver is a man who drives the Bullworth Academy bus. He has short red hair and beard, and wears a pale blue t-shirt.
The bus driver is technically not a character. Rather than being attached to a skeleton, he is graphically part of the school bus model and does not even have a lower body. He is not animated, and has no voice actor.
He is not Tobias Mason, but is often mistaken for him as they both have red hair and beards.
