Eleven people were injured in a Bus accident Saturday evening in Garfield County. A Roaring Fork Transportation Authority commuter bus was traveling west on Hwy 82. It attempted to pass a slow moving tractor. Police say the bus driver quickly changed lanes, then lost control, causing it to strike a concrete barrier and rolled on its left side. The rear of the tractor had running and flashing lights but not a slow moving vehicle emblem as required. This crash remains under investigation.
