To add to what Honny said.... any MSC whose schedulers do not put your safety first are just not worth your time at any time of the year.
My policy is that if schools near home or along the way to the shop, are closed for poor driving conditions, I stay off the roads. For a weekend with significant snow or ice, assume that schools would close. In my area, many public facilities, entertainment venues, and civic and religious venues cancel activities, which I equate with school closings for weekend travel.
