The three-vehicle crash at the Dawson-Forsyth County line Wednesday that sent several people to the hospital occurred, authorities said, when a teenage driver suffered a medical episode. According to the Forsyth County Sheriff's Office, the 17-year-old White County resident was traveling east on Hwy. 53 about 7:45 a.m. in a 2002 Chrysler Sebring when he struck the rear of a 2007 Honda Accord in front of The Church at War Hill. The impact sent the Honda, which had been stopped to make a left turn into the church parking lot, into the westbound lane of Hwy. 53 and the path of a 1998 Dodge Ram 1500.
