It's being called one of the scariest moments ever caught on tape. Wendy Cobb, 40, was driving to work when a 2x4 smashed through her windshield. It missed her by inches.
Cobb, of Shelby, North Carolina says she was videotaping two vehicles so she could report the drivers for playing what looked like a cat-and-mouse game on the highway.
"I remember as it was coming up from the back wheels of the trailer thinking, 'That's not really going to fly up like that is it?'" Cobb told INSIDE EDITION.
In the video, you can see the piece of wood lying in the road. The wheels of the trailer flip it up before it shoots straight into the windshield.
Dangerous pieces of debris scattered on highways across the United States cause 25,000 accidents a year, many of them horrific.
Brenda Shaw of Utah was impaled by an eight-foot long pole that fell off a truck and hurtled through her windshield and straight into her face. Miraculously, Shaw survived.
And in 2004 a piece of wood hit the windshield of a car driven by 24-year-old college student Maria Federici. She was left blind and disfigured.
Cobb was lucky. She had dropped off her two children at school just minutes before her brush with death.
