The way it goes, Dude, is that when we close a road you can be subject to fines, total cost of rescue, if necessary, and you are reminded by the closed road sign that your insurance company will not recognize your name when you get stupid.
But aside from that we have enough problems with stupidity behind the wheel on the open roads we try to make safe.
The third worst thing anyone can do is follow too closely behind a plow truck. The second worst thing is to try to pass one on a corner. And the worst thing anyone can do is try to pass a plow truck on the right when it is plowing the "turn lane" in a three lane road.
The third worst will get you a cracked windshield, the second will kill you and the first will collapse your windshield and fill your rig with snow...possibly killing you.
DO NOT ask how I know these things!
And thank you for your support!
