A Ford F-150 pick-up truck had been traveling southbound in the right lane when it stopped “just past the off-ramp for Exit 29,” a news release states.

A tractor-trailer traveling behind the Ford reached the stationary vehicle and was not able to brake in time or avoid hitting the truck. The impact caused both vehicles to run off the right side of the interstate. VSP responded at 5:46 a.m.

The driver of the pickup, who had been wearing a seatbelt, is hospitalized at Johnson City Medical Center with life-threatening injuries. VSP stated that the tractor-trailer driver was not injured.

Police noted that visibility at the time of the crash was “extremely limited due to the severity of the fog.”
