Skjutsgruppen is a non profit carpooling initiative with over 70 000 members. When members travel towards the same direction, be it by car or boat or bus, they offer the empty seats in their vehicle out to others. The non profit aspect of Skjutsgruppen means that either the cost of the travel is shared or the empty seats are offered free of cost. There is no profit involved.
You can rideshare either just the one time from point A till point B or start a local group for commuting, a sports team or an event. Download the app and try.
