Update (November 19): Crash investigators have completed the reconstruction of the school bus crash. The driver was found to be traveling 43 miles per hour in a 40 mile per hour zone. The driver told investigators that she was checking the rearview mirror when she drifted to the right and that the rear wheel dropped off the roadway. She lost control while attempting to correct the bus path, causing the bus to travel into the opposite lane, and then roll over onto the side.

The driver was found at fault in the single vehicle crash. No citations will be issued.

The Baltimore County Police Department's Crash Team has begun an investigation of a Baltimore County Public School bus crash that occurred this morning in the 10800 block of Greenspring Avenue in Precinct 4/Pikesville.

The bus, en route to Pikesville Middle School, rolled over and came to rest in a wooded area along the side of the road. The Crash Team is in the beginning stages of the investigation; it has not identified a cause for the crash at this time.

Police, Fire and EMS personnel were dispatched at 7:29 a.m., with the first medic unit arriving at 7:37 a.m. EMS personnel found that the driver and the students had evacuated the bus on their own, before first responders arrived. Fire personnel conducted a thorough search of the bus and found no one trapped.

A total of 10 students were riding the bus at the time of the crash. Five of the students and the bus driver, a woman, were transported to local hospitals for treatment of minor injuries. The parents of the other five declined treatment.

The bus driver was transported to Sinai Trauma; the students went to Johns Hopkins Hospital's pediatric center and to Greater Baltimore Medical Center.
