WEST FORSYTH -- A pedestrian was seriously injured after being hit by a vehicle Wednesday afternoon in the parking lot of a gas station on Canton Highway at Heardsville Road, which is just east of the Cherokee-Forsyth county line.

According to Forsyth County Sheriff’s Cpl. Robin Regan, a 44-year-old man from Cumming was travelling on Canton Highway (Hwy. 20) when he lost control of his Volvo and drove into the Marathon Gas Station parking lot at 4644 Canton Hwy., striking a parked Chevrolet Colorado.

The impact knocked the Chevrolet into its driver, also a 44-year-old man from Cumming, who was standing outside the vehicle.

He was thrown into the side of the building as the truck rotated after being struck, causing him to receive multiple injuries, according to Deputy Epifanio Rodriguez, also a spokesman for the sheriff’s office.

The man was reportedly unconscious when EMS personnel arrived. A medical helicopter transported him to Atlanta Medical Center after being initially called to reports of critical injuries.

He has since gone through surgery for serious but non-life threatening injuries.

The Volvo reportedly came to a rest after hitting the side of the gas station building, putting a hole in the wall and shifting the front wall of the structure about an inch.

According to the sheriff’s office, the estimated cost of damage to the gas station is $20,000.

The driver of the Volvo reportedly told deputies he passed out and did not remember the crash.

He said he was on his way home from work when he felt the left side of his body go numb as he went through the intersection and did not remember anything after that.

He was taken to Northside Hospital-Forsyth to be evaluated for a medical condition.

A crash investigation unit is determining the cause of the crash, Rodriguez said.

Drugs and alcohol are not suspected in this case. Charges have not yet been filed and will depend on the outcome of the investigation.
