Tachograph Testing

A tachograph is a device fitted into a commercial vehicle to measure the engine speed.

There are two types of tachograph; analogue and digital (In accordance with the law, all vehicles registered on or after 1 May 2006 must have a digital tachograph fitted. )

Analogue tachographs:

  • Must be calibrated and sealed by an approved vehicle manufacturer or calibration centre
  • Checked every two years
  • Recalibrated every six years

Digital tachographs:

  • Must be calibrated every two years
  • Must be calibrated after any repair
  • Must be calibrated if the vehicle registration number changes
  • Must be calibrated if UTC is out by more than 20 minutes
  • Must be calibrated after an alteration to the circumference of the tyres or characteristic coefficient.

We have been coming to Oxford City Council for many years to have our fleet of vintage buses put through their MOT. We are very impressed with the service provided as they are completely impartial and experienced in testing many different types of vehicles. Oxford Direct Services are one of the very few places in Oxford that have the facilities to carry out class 5 MOTs on private buses.
