SOUTH FORSYTH — Two south Forsyth teenagers were injured in a single-vehicle crash Monday morning on Peachtree Parkway (Hwy. 141).

A 14-year-old female passenger sustained critical injuries after she was thrown from a gold Chevrolet Silverado about 7:50 a.m., according to the Forsyth County Sheriff’s Office.

Robin Regan, a spokesman for the agency said the truck apparently left the parkway at Hwy. 141 and Bagley Road and went down an embankment after rolling six times, running the girl over. At one point, the truck reportedly came back onto the road on its roof.

The girl was taken by ambulance to North Fulton Hospital. After she was stabilized, she was flown to Children’s Healthcare of Atlanta at Scottish Rite Hospital, Regan said. The 16-year-old male driver also was taken to North Fulton.

Hwy. 141 south was closed at Bridle Ridge Drive for about two hours, with traffic diverted at Bagley Road.

The sheriff’s office is handling the investigation. As of Tuesday, no charges had been filed.

According to Regan, the initial investigation revealed the driver was traveling at a high rate of speed and left the road in a curve while heading south on Hwy. 141.

No other vehicles were involved. The names of the teenagers have not been released, though they both attend Lambert High School, according to Jennifer Caracciolo, spokeswoman for Forsyth County Schools.

School was out Monday for the Labor Day holiday. Students led a prayer circle Tuesday morning at Lambert, where counselors were available, Caracciolo said.
