Investigators are looking into whether the driver of an SUV suffered a medical emergency when she somehow slammed into an MBTA bus in Saugus, Massachusetts on Sunday afternoon.
The crash happened just before 4 p.m. near Essex and Felton streets, according to MBTA Transit Police.
The Route 429 MBTA bus was heading toward Lynn when it was struck head-on by a Ford SUV being driven by a 37-year-old woman, investigators said, adding that the SUV may have hit a third parked vehicle, which caused it to veer into the MBTA bus' lane of travel.
"She clipped the silver car and then all of a sudden started turning left. There’s no way the bus could stop. She just spun," said witness Taryn Medeiros, who was driving behind the SUV in her own vehicle.
All four passengers on board the bus and the bus driver were taken to local hospitals for minor injuries, while the driver of the SUV was taken to a local hospital for serious injuries.
Nearby drivers stopped in the middle of the road to see if they could help at the scene. Lenny Fauci said the driver of the SUV was unconscious when he checked on her and that she was by herself, "cause I checked the backseat to see if there were any children. I saw car seats. One car seat."
The exact cause of the crash remains under investigation.
