Ya’ know I always wondered how those big 18-wheelers actually removed the snow from the tops of their trailers during a snow storm. Now I don’t know about where you live, but here in New York State it’s against the law to drive around with a snow covered roof. The fear is that the snow (or ice) may go flying off and into somebodies windshield. It’s a valid concern and one that I’ve actually seen happen on the Long Island Expressway. This becomes especially dangerous if you’ve experienced below freezing temperatures as what you have then are large projectiles that have the ability to cause some major damage. As for these trucks, I’m sure there are some kind of regulations against ripping down the interstate with 3-feet of snow on your trailer, but for the life of me I have no idea what they are. What’s really interesting here is that the driver of the following car had the foresight to whip out their cellphone and take the wild video you see here.
