How often must a digital tachograph be checked and calibrated?

Unlike analogue tachographs where the tachograph head is checked every two years and re-calibrated every six years, digital tachographs must be fully re-calibrated:

  • every two years
  • after any significant repair (particularly involving gearbox)
  • if the vehicle registration number has changed
  • if there has been a change in tyre circumference
