Tachographs are a key part of the transport industry and make it possible to track the driver’s driving time, rest periods and working hours. Understanding tachograph signs is essential for drivers, hauliers and anyone involved in the transport of goods. In this blog, we will explore the meaning and interpretation of different tachograph symbols.

What is a tachograph?

A tachograph is a device installed in trucks that records driving, speed, distance and time data. It is used to ensure compliance with legislation on working time and rest. Vehicles that must be equipped with a tachograph include:

  • Lorries with a maximum permissible mass of more than 3.5 tonnes.
  • Vehicles with more than nine seats (including the driver).
  • There are also exceptions.

Digital tachographs are mandatory for all vehicles placed on the market for the first time after 1 May 2006. Analogue tachographs were used before that date. From 1 July 2026, tachographs will also have to be installed in vehicles over 2.5 tonnes.
