6 Year Old Boy Drives School Bus In Milwaukee (AP) MILWAUKEE A six-year-old Milwaukee boy tried to drive himself home in a school bus. Authorities say the kindergartner got mad at his teacher and slipped out of the building and climbed into an idling school bus. The boy then drove around the circle drive in front of the school twice before driving away. No one was hurt, but the boy did hit a parked car, a tree and knocked down a fence. The bus was empty at the time. Milwaukee police are investigating.
