How do you behave with probably a smooth road?

Hello! I’ve had my car license for a few days now and I’ve driven about 150 kilometers so far. I don’t have much experience at all. However, from tomorrow until Friday I have a vocational school (about 35 kilometers away) and I don’t want to go by car as before, that’s insane …. In itself, no bigger problem, only the weather report says strong snowfall and snow/ice rain for our region, so it’s going to be really smooth. Now I wanted to ask you how I should behave best. I don’t want to play the traffic barrier #1, but I just want to arrive safely ^^ I’m very grateful for some tips. I’m very grateful for your help.
