One driver had a lucky miss after a metal bar went through his windshield, giving him a minor cut on his head.

According to Washington State Patrol Trooper Rick Johnson’s Twitter, the driver was traveling soutbound on Interstate 5 near 320th Street in Federal Way when the metal bar went through his windshield, just grazing the side of his head.

Washington State Patrol does not know where the metal bar came from, and Johnson is asking for anyone with more information to call WSP.

Johnson posted pictures of the accident January 29 around 6 p.m. on his Twitter.
