In this case, a major issue was that the weather was rain transitioning to heavy snowfall. VDOT couldn’t pre-treat the roads because the rain would wash it away, and they couldn’t clear the roads of snow fast enough to prevent ice formation. Similar to the Atlanta “snowmageddon” in 2014, once you have enough 18-wheelers stopped, they can’t start moving again on ice, and they (plus the normal car traffic) clog the roads enough that the snow trucks can’t operate. I am having difficulty envisioning how a hypercompetent northeastern DOT could do better in these circumstances, other than improved communication.
