To relieve pressures within the tachograph and vehicle maintenance industry, the requirement to calibrate or inspect tachographs periodically has been relaxed.

Until further notice, all tachograph calibration and inspection expiry dates are extended by 3 months.

Any faults with the tachograph system must still be repaired as normal, the tachograph system must function as required by the legislation, and the system is still required to be sealed in line with the requirements. Initial calibrations are to continue, and any changes to the various parameters (such as tyre size, vehicle registration and so on) will also require action as normal.

Further guidance will be issued when available.

This guidance includes:


  • Extension of current training certificate expiry dates
  • Periodic quality control (QC) checks
  • DVSA examiner visits
  • Tachograph centre equipment calibration
  • April 2020 workshop cards
  • 1C sealing requirements
  • Phoenix seal
  • 1C tachograph retrofit program
