Norway has gone Norwegian when comes to the country’s reaction towards drivers who violate the low speed limits. The speed limits are among Europe’s lowest, while the reactions are certainly Europe’s toughest. Motor roads with two lanes (Class A) may have a max speed of 110 km/h. The rest have a max speed of 90km/h or 100km/h. The common speed limits outside urban areas are 60, 70 or 80 km/h.
