Yes you can! All renatal cars are equipt with good winter tires to drive on the roads. the roads are maintained very well. Ofcourse you always need to keep an eye out for wild animals and icy conditions.
But something very unique and cool thing driving in winter is that you can drive on the ice. In our area you have special ice roads for cars. These roads are usually opened at the end of January or the beginning of February. They lead into the archipelago, which means you are driving on the sea! This is a highly recommended experience.
