A motorist with a dash cam recently captured this footage of a sheet of ice flying off the top of a tractor trailer and smashing his windshield.

It happened on March 20th in Buafflo, New York.

“I was driving down the I-90 around Batavia, NY on my way home to Buffalo, NY when ice flew off the top of a tractor trailer giving me no time to respond. The ice smashed the window up near the roof line. If it were a couple inches lower it would have come through the window and caused serious injury. This was by far the scariest moment in my lifetime where everything slowed down and I saw my life flash before my eyes,” the motorist wrote.
