Snow & transport

So.. this might be a dumb question but I was wondering how people get to work when it has snowed as much as it has the last few days? Do busses still drive? I can’t imagine still biking to work, that seems too dangerous.

I’m moving to Trondheim in 3 weeks and I cannot get the question out of my mind. Tusen takk!

Edit: thanks so much for the answers! I’ll definitely take some of your suggestions and take tips into consideration :D
