A Forsyth County teenager was injured in a wreck Wednesday on Castleberry Road by the Cumming Fairgrounds.

William Reid Wigington, 17, was flown to Grady Memorial Hospital in Atlanta with a “non-fatal head injury” after his pickup truck smashed into the side of a semi-truck, said Robin Stone, a spokeswoman for the Georgia State Patrol.

The driver of the tractor-trailer, 62-year-old Vladimir Kukharchuk of South Carolina, was charged with failure to yield while entering or crossing a road, Stone said.

The wreck occurred about 1:50 p.m. when Kukharchuck attempted to make a left onto Castleberry Road from the parking lot across the street from the fairgrounds.

“He didn’t realize the truck was coming,” Stone said. “He tried to either speed up or back up, but he didn’t have time to do either.”

Wigington’s 1999 Ford pickup “ended up sliding under the truck,” she said.

Forsyth County firefighters had to free Wigington from the wreckage.

Kukharchuk was not injured in the collision, which tied up traffic on Castleberry for more than an hour.

Both drivers were wearing seatbelts, she said. Alcohol and drugs were not factors in the wreck, however Trooper Mark Cox did say that the speed of the F-150 was also a factor in the crash.

The state patrol did not have an update on Thursday on Wigington’s condition.

However, his friends shared posts on social media sites indicating that he will be “OK.”

Wigington is a rising senior at Forsyth Central High School, according to school system records.
