Command also requested Rush rescue be dispatched to assist. Engine 2 was first to arrive with United 13 (C.E. Daly) in Command finding 2 cars one with heavy front end damage with the passenger still in the vehicle and the Other vehicle with severe passenger side damage with the driver confined. The engine crew removed the glass from the rear driver side window and manually opened the lock providing access to the patient. Once the vehicle was stabilized crews unlocked the drivers door and had to dig the dirt from the embankment to fully open the door. Crews were then able to remove the patient. While the first patient was being extricated the other 2 patients in the other vehicle were being packaged by EMS. A total of 3 victims were transported from the scene by ambulance. Crews remained on scene controlling hazards and traffic while PSP handled the investigation. We would like to thank Rush fire company for the assistance with the incident.
