Tachograph
A tachograph is a device installed in commercial vehicles to automatically record driving time, speed, and distance. It is a key tool for enforcing driving time regulations and ensuring compliance with road safety laws. Tachographs store data on driver activity, including breaks and rest periods, helping authorities and fleet managers monitor adherence to legal limits.
There are two main types:
- analogue tachographs, which use waxed paper charts, and
- digital tachographs, which store encrypted data on driver smart cards and internal memory. Digital versions can be integrated with telematics systems for real-time monitoring and compliance alerts.
