Money over children...

Until now, most states prohibited school bus advertising—in fact, only nine states allow it. But faced with unprecedented budget shortfalls, many states and school districts are considering what was once unthinkable: selling ads on the outside and interiors of school buses. Around the country, long-standing laws protecting students from school bus ads may be overturned. If passed, new legislation would transform school buses from Rhode Island to Washington into traveling billboards for everything from fast food to violent and sexualized media.
