If an analogue tachograph breaks down, it must be replaced with a digital tachograph. Digital tachographs will be replacing analogue ones as the vehicle fleet is being renewed.

Drivers of vehicles fitted with digital tachographs, companies owning vehicles with digital tachographs, garages/workshops repairing tachographs and inspectors from the Norwegian Public Roads Administration and the police must be familiar with digital tachographs.

In order to use a digital tachograph you need a tachograph card.

There are four types of tachograph card

  • Driver card
  • Company card
  • Workshop card
  • Control card

The most important difference for tachograph users is that data on driving time and rest periods are registered in the tachograph and on a tachograph card (smart card) instead of on diagram charts. Tachograph cards are issued to drivers, transport companies, tachograph repair shops and inspectors.

The digital tachograph is a small computer that is installed in the vehicle. Information about the vehicle’s activities is stored continuously in the tachograph.

Driver card

If you are going to drive a vehicle with a digital tachograph, you will need your own driver card. Insert the card in the vehicle unit before you start driving. The driver card records information about your driving, and is thus personal.

Company card

Transport enterprises must have a company card, which is used to download data from the vehicle unit. This must be done at least once a month.

Workshop card

Mechanics working in an approved workshop for digital tachographs must hold a workshop card in order to perform work on the tachograph.

Control card

Inspectors must hold a separate control card in order to check the driving time and rest periods recorded by the tachograph’s vehicle unit.
