Noah Williams says it happened near Exit 6 on the Turnpike while he was driving behind an 18-wheeler truck with snow still packed on its roof.
"It smacks my truck, smacks the windshield. I had a bunch of glass fly into my face," Williams said. "I almost lost control."
Williams, who says he thought he was going to die, even attempted to flag down the driver of the 18-wheeler but was unsuccessful.
Incidents like this are unfortunately not uncommon and are a big concern for drivers.

Officials in New Jersey are reminding drivers this week of the law to clear their car's roofs and hoods of snow before getting behind the wheel, especially with more inclement weather in the forecast.
Williams says he's been driving a truck for six years and this is the first time something like this happened.
"It doesn't take that long to go to your car wipe the snow off and save a life," he says.
