What is the primary function of a tachograph?

The primary function of a tachograph is to record vehicle speed and the driver’s hours of service. This tool is crucial for ensuring compliance with regulations governing driving time and rest periods, which are designed to enhance road safety by preventing driver fatigue. By accurately measuring how fast a vehicle travels and how long a driver has been on duty, tachographs help in minimizing the risks associated with long driving hours.

In addition to contributing to safety measures, the data collected can also be used for monitoring driver performance and managing compliance with legal requirements in the transportation industry. Therefore, the tachograph serves as an essential device for both regulatory enforcement and operational management in commercial driving.
