A Yelm man was injured when a piece of steel went through his windshield as he drove on Interstate 5 near DuPont on Saturday night.
The State Patrol says the 23-year-old saw the chunk of steel coming at him. It hit him on the forehead, above his right eye.
The man was taken to the hospital, where he was in satisfactory condition Sunday.
Troopers believe the steel chunk was run over and sent airborne by another vehicle. It was not thrown from an overpass.
