Driving off public roads.
I am not an activist....
Semi open roads used for lumbering, forest cultivation, hunting, access to cabins and other houses or businesses, farm roads, "Fire Routes" etc..... are alle no go roads unless otherwise posted.
The really important reason to be aware of this is, the fines start at 15000 NOK. That means a little trip in the wild can cost 1700 Euros..
Norway is among the World Champions og traffic violation punishment.
One of the reasons I leave my country as soon as possible for vacation drives.
