PULASKI COUNTY, Va. (WDBJ7) -- UPDATE:
A tractor trailer driver has been charged after a 7-vehicle accident that happened on Interstate 81 in Pulaski on Wednesday.
Miriam U. Campbell, 32, of Gastonia, North Carolina, was charged with reckless driving.
According to Virginia State Police, Campbell was driving south when her tractor trailer sideswiped another tractor trailer in the adjacent southbound lane.
