When driving a vehicle with a digital tachograph, you should:

• use the driver card every day you drive, starting from the moment you take over the vehicle
• set the mode switch to the correct activity and make sure to use it
  throughout your working period to record other work, periods of availability, rests and breaks
• remove your driving card when the vehicle is taken over by another driver, or when the vehicle is not under your custody or if another driver could drive it
• protect your card, keep it clean and do not bend it
• record the country in which you begin and end your daily work period
  (always doing this at the start and end of the period)
• manually enter your activities if any – other work, breaks, rest and periods of availability – since you last removed your driver card from a tachograph.

From 1 January 2008, you must be able to produce, whenever an enforcement officers requests them:

• your driver card
• any manual record and printout made during the current day and the
  previous 28 days and
• analogue charts for any vehicle fitted with an analogue tachograph driven by the driver in the current day and the previous 28 days
