Authorities say a Dixfield teenager is expected to survive after riding on the roof of a car that flipped over, pinning him underneath. Police say the teen was on the roof of the car in Mexico at about 4:30 p.m. Thursday when the 15-year-old driver lost control on a dirt road. Rumford Deputy Fire Chief Richard Coulombe tells the Sun Journal, the driver backed toward a curve, got into the soft shoulder on the outside of the curve and flipped the car over, landing upside down in a drainage ditch. The teen on the roof had his leg pinned. Firefighters from several departments lifted the vehicle so ambulance crews could free the boy. He was taken to the hospital with injuries not considered life threatening. No names were released.
