A Mashpee ambulance rolled over after a head-on crash in Falmouth on Friday. The ambulance was transporting a patient to Falmouth Hospital and was traveling west on Route 151 with its emergency lights on when it was hit. “Multiple eastbound operators had pulled to the shoulder of the road and yielded to the ambulance,” Falmouth Police said. “One operator did not yield, crossed the center line to avoid cars on the shoulder and struck the ambulance head-on.” Four people were taken to the hospital with non-life-threatening injuries. Among the injured were two Mashpee paramedics and a patient in the ambulance. The vehicle that struck that ambulance was a Toyota Camry. The crash caused the ambulance to hit a Jeep Grand Cherokee head-on before coming to a rest on its driver’s side.
