There was only one lane open on the highway and it was clear you could not see far. One lane means you are also likely on ice, yourself, if the other lanes are covered.
You go slow and occasionally tap your brakes as you move forward. Ideally, you pull off if you are concerned, but you don’t plow forward at 70 MOH with a full load and not seeing far, while driving on a known icy interstate.
This is not rocket science for anyone from the area, but those on an Interstate are most likely to be from other places.
These people were stupid, especially for the ones who know what to do, and didn’t.
Perhaps, but still cannot verify high speeds like 70. Likewise, this was a dusting so while people may decide to follow the leader, often there is no problem driving the other lane. I’ve driven plenty myself in storms and it takes quite a few inches before giving up driving another lane. It wasn’t “open”, just follow the leader.
