An investigation is underway after authorities say they believe a tractor trailer ran a car off of Interstate 81 Thursday morning
Reportedly, the car was headed north just before 11 a.m. when the driver says a tractor-trailer suddenly swerved into her path and forced her off the road. The car hit an embankment on the side of the road and spun.
The car was heavily damaged and was not drivable, but both the driver and her dog were able to get out of the car without a scratch.
Virginia State Police has not officially determined the cause of the accident.
