San Francisco Bus Slams into Dump Truck

San Francisco police say a dump truck on Geary Boulevard slammed its brakes in traffic Friday afternoon, causing a MUNI bus driver to in turn slam his brakes, but the bus ended up hitting another dump truck.
When the bus slammed into the dump truck, one passenger told ABC7 News some people were thrown on the floor. A MUNI spokesman said a total of 20 people were injured. Twelve people were taken to local hospitals, but all were released by Friday night. Eight people were treated on the scene.
