Five prisoners being transported in a bus, as well as two of the guards watching them, were injured during a four-vehicle crash on southbound Highway 99 on Friday afternoon.
The collision involved the bus operated by a private company called Prison Transportation Services of America as well as two pickups and a car, said California Highway Patrol Officer Eric Parsons.
One of the vehicles failed to slow for stopped traffic south of Briggsmore Avenue, causing a chain reaction of rear end collisions. Parsons said investigators are still trying to determine who is at fault.
The prisoners – four men and one woman – and guards were taken to local hospitals with minor injuries. No one else was injured in the crash.
