The Muni bus crashed just after midnight, San Francisco fire Lt. Ken Smith said. An inbound Polk-19 bus apparently collided with a small truck in the intersection, sending the bus coach off the roadway into some bushes. Early reports that the bus overturned were wrong.
Nine people were injured and needed medical attention at the scene; seven of them were taken to a hospital with moderate injuries, including the driver of the bus coach. The driver of the truck was pinned inside the vehicle and needed rescue crews to help free him. He suffered serious injuries.
Muni officials aren't saying anything abut the crash just yet. The San Francisco Police Department and Muni are jointly investigating the cause of the crash.
Crashes are piling up for Muni. The agency is already under fire for of a number of collisions in the last year.
The NTSB is still investigating the crash of an L train that injured 48 people in July. It happened when one train slammed into another at the West Portal station. A month later, a Nissan Pathfinder was crushed between two Muni streetcars on Noel Street. A couple days after that, 14 people were injured when a train rear ended another on the Embarcadero.
