All buses and lorries used in Norway for transport to which drivers’ hours regulations apply must be equipped with a digital tachograph.
All vehicles registered after 9 December 2006 must have a digital tachograph installed.
A driver card is used in a tachograph to register when you are driving, doing other work, taking a break, or resting. All drivers must have their own card.
It is the Norwegian Public Roads Administration and the police that inspect driving time and rest periods in Norway.
