While returning from an early call Ambulance 919 came upon a vehicle off the roadway on it's side with one patient trapped inside. The rescue assignment was dispatched to Route 15/340 to Ballenger Creek Pike. Chief 903 on the scene confirmed the dispatched location and established command. As the remainder of the assignment arrived on the scene, tasks were given and the crews went to work. It took about twenty minutes to free the patient from the vehicle. The patient was assessed and was transported to Meritus Medical Center via Medic 198. Command was terminated and units went in service as ready.
