I guess not everyone has the expirence needed for driving in moderate to severe winter weather. But you'd think it was common sense that if the roads are slick, you DON'T slow down when going uphill. Downhill and on level ground, yeah you want to slow down. But going uphill you need a bit more speed if you want to make it all the way up. This morning I had several encounters with motorists slowing down on hills and barely reaching the top. When traction is limited, especially on long hills, speed up a little. That will give you the best chance of avoiding getting stuck on the hill.
I actually slid a little going downhill, but thankfully didn't hit anyone or anything. Was very close to two other cars though. Much closer than I'd like to get in those situations. Snowplows were having a hard time keeping up with the snow, as it kept coming down for a good hour after I got home. Good news is that as long as most of it was cleared up the rest melted when the sun came up.
