Police said the crash happened shortly after 3 p.m. at the intersection of Route 156 and Mile Creek Road. Six children were riding the bus at the time.

None of the injuries were deemed life threatening, and a spokesperson for the Shoreline Medical Center said all three of the clinic's patients were discharged Friday evening.
