It is the truckers on I80...most have never driven in snow and it is really tough on the open I-80...wind blows there all the time even in good weather...
I lived in Colorado Springs and worked in Teluride. one winter...got to Monarch Pass and the sun was out..and it said TRUCKERS chain up...well most did not because the sun was out...well they were all over the road when you got up on the pass..
I went through conditions like that on I-70 going through Illinois several years ago. I stopped for the night to get off the highway. The next morning, I saw numerous overturned trucks and cars stuck in the snow.
Wow!
Reminds me of some of the lake effect snow we’d get off Erie back when I lived in NE Ohio.
Unfrozen lake + sharp NW winds = big snow
