A digital tachograph is an electronic device used in commercial vehicles to record driving time, speed, and distance. It helps ensure that drivers comply with regulations regarding working hours and rest periods, promoting road safety and fair competition in the transport industry. The data collected is stored on a secure card, which can be accessed by authorized personnel for analysis. These devices are mandatory in many regions, including the European Union, for vehicles over a certain weight. Digital tachographs replace traditional analog models, offering more accurate and tamper-resistant data. They also facilitate easier monitoring by regulatory authorities, enhancing compliance with transportation laws.
