About
A clearer view of your time
tachograph.lt helps drivers and transport operators understand card and vehicle tachograph records. Upload multiple DDD files, inspect vehicle activities and compare them with a specific driver card. Vehicle analysis supports G2 v2 files. Only properly attributed, comparable minutes and matching vehicle/odometer observations are compared. Missing data is neither rest nor an automatic infringement. DDD signatures are verified against ERCA keys. Export PDF and JSON reports, plus CSV for selected card periods. Review findings are not final legal conclusions.
