The South Park Elementary school bus is a yellow 1979 International Harvester S-series "Schoolmaster".
It is usually seen at the beginning of each episode, picking up the boys from the Bus Stop. It is a recurring vehicle in South Park, and was a major hallmark in the series. Since the death of its driver, Veronica Crabtree, its iconic value has diminished, appearing inconsistently between seasons, and with fewer prominent appearances. The bus was driven by the elementary school janitor, Jose Venezuela. The bus is currently driven by an unnamed female.
