As you dig out from two feet of snow or more, keep in mind the dangers aren't just on the road. Drivers just let it fly off, and possibly into the windshield of any nearby car.

Quote from the article:

Do you know that's the law to clean that off?" Keeley asked one driver. "Oh, the one that's on my roof right now?" the driver said. "Or anyone," Keeley said. "No, I didn't know," the driver said. The message hit especially close to home for one Easton man lost his wife to flying ice five years ago when a chunk flew off of a tractor-trailer into her car, killing her instantly.
