Due to the low population density, narrow shape and long coastlines of Norway, its public transport is less developed than in many European countries, especially outside the major cities. The country has longstanding water transport traditions, but the Norwegian Ministry of Transport and Communications has in recent years implemented rail, road and air transport through numerous subsidiaries to develop the country's infrastructure. Under discussion is development of a new high-speed rail system between the nation's largest cities.

Norway has the world's largest registered stock of plug-in electric vehicles per capita, with Oslo recognised as the EV capital of the world. In March 2014, Norway became the first country where over 1 in every 100 passenger cars on the roads is a plug-in electric. The plug-in electric segment market share of new car sales is also the highest in the world. According to a report by Dagens Næringsliv in June 2016, the country would like to ban all gasoline and diesel powered vehicles as early as 2025.

There are departures to most European countries and some intercontinental destinations. A direct high-speed train connects to Oslo Central Station every 10 minutes for a 20 min ride.
