SOUTH FORSYTH — One person was taken to an area hospital in what authorities said was serious condition after a single-vehicle wreck Wednesday morning on Ga. 400.

According to Pete Sabella, a spokesman for the Forsyth County Sheriff’s Office, the driver’s vehicle was the only one involved and there were no passengers.

Brian Kime said the incident occurred in front of him as he was traveling north on Ga. 400 about 7:50 a.m. He was in the right lane preparing to exit at McFarland Parkway (Exit 12) when a burgundy Volvo sport utility vehicle crossed into his lane.

“I thought nothing of it until the SUV went off the roadway. I never saw brake lights,” Kime said.

He said he helped pull the man, whom he described as possibly in his mid-40s, from the vehicle and performed CPR for “several minutes” before a second Good Samaritan took over.

“EMS arrived shortly thereafter,” Kime said. “EMS eventually hooked him up to what I’m assuming was a defibrillator and loaded him into the ambulance.”

According to the sheriff’s office, a cause of the crash remains under investigation.
