I definitely think you should address this on the evaluation, but unfortunately, some businesses and colleges just don't care about safety. I live in North Carolina, and we mostly get ice first, then some snow on top of it which is way more dangerous than just driving on snow alone. I can think of at least 2 instances in the past 4 years where I was told that if I wanted my job then I would HAVE to get there, even when the ice was so bad it knocked out power to over half the city. Both of these cases were restaurants, and of course, the one time I did get there after driving 10 mi per hour and still sliding all over the road NO ONE came in AT ALL (though I was required to stay for my entire shift, just in case. Hopefully this year, my boss (not a restaurant this time) will be a little more concerned about our safety than about the bottom line.
As to a school incident, when DH and I lived in Boone, NC (in the mountains) his college made the statement that unless there was enough snow to create a State of Emergency (which had happened in the 90's) then school would be in session. DH was forced to walk to class because his truck would not make it on the hills in the area.
