Pennsylvania police are on the lookout for a hit and run motorist who is believed to have caused a rollover school bus crash that injured fourteen students.

The crash happened at 8 a.m. this morning on Route 30 near Lancaster, Pennsylvania. According to the Lancaster County DA’s Office, the crash happened when a passenger vehicle driver attempted to pass two trucks and their escort vehicles. From a statement from the DA: “Initial information indicates the wanted driver (described only as a male) caused the crash by attempting to pass two tractor-trailers and their escort vehicles while headed east on Lincoln Highway East. The bus was traveling west. As the sedan driver was making the pass (into the opposing lane), the bus was approaching from that lane. The sedan veered back into the east lane, striking the rear of an escort vehicle. That escort vehicle was pushed into the westbound lane and side-swiped the bus, causing the bus to yaw and impact one of the tractor-trailer’s load. The bus then tipped onto its side.”

The car driver fled the scene after the crash.

Sixteen people were injured altogether, including 14 students, the school bus driver, and the driver of one of the escort vehicles. One of the students was ejected in the crash and then pinned under the bus. That student is listed in critical condition.

Police say that they are looking for a late model white sedan with front end damage driven by a male. The car was last seen driving east on Route 30. If you have information on the crash or the car, you’re asked to call police at 717-291-4676.
