Authorities say a school bus flipped on its side in a hit-and-run accident in eastern Pennsylvania, sending more than a dozen people to the hospital, including two students with trauma injuries.

Emergency responders in Lancaster County said the Lancaster Mennonite school bus was taking students to school when the crash occurred shortly before 8 a.m. Wednesday in East Lampeter Township. A witness told WGAL-TV that a vehicle trying to pass an oversized load collided with its escort vehicle and spun into the bus before fleeing. Police were seeking a light colored sedan.

The 14 students, the bus driver and another driver were taken to Lancaster General Hospital, where spokesman John Lines said two students with trauma injuries were being transferred to children's hospitals and everyone else was treated and released.
