A Tachograph is a device installed on vehicles that automatically records vehicle and driver data, such as distance, speed, and driver activities. The stored data can be periodically downloaded using the RDD (Remote Data Download) feature for further monitoring and reporting. The Tachograph module helps fulfill legal obligations by managing the tacho archiving requirements of a company.
The data in the Tachograph module is legacy data that cannot be edited.
