Winter driving in Sweden

I used to live south of Stockholm and thought I knew what winter driving is. Hilarious in hindsight. You live you learn, and this article is about what I've learned after several winters up in Norrland. The winters are getting warmer, but we still get real ones north of the capital. In this post: the laws, the tires, the cars, how to drive, what to have in the car, how to plan.
