Against our expectations, driving through the winter landscapes with frozen roads was not that horrible, it’s enough to drive slowly, not to forget that the road signs don’t serve only for decoration and everything will be perfect. The snow is regularly removed from the roads all over these two countries, so it is not at all an obstacle.
Finnish and Norwegian drivers appeared to be patient and respectful enough not to let any sign of possible irritation. However, beware of the elks on the road! There are thousands of accidents involving animals per year, and I promise that killing an elk or being killed by an elk shouldn’t make part of your Finland experience.
What is amazing in Finnish roads is the fact that due to so many islands, the road can finish abruptly, you have to wait for a ferry, and then (for free) you get to another bank. The ferries (almost all) work 24 hours, and are considered really like a continuation of the road. Fantastic!
