The rule
Digital tachographs in all EU member states record driving and rest periods strictly in UTC. When making manual entries upon card insertion, entering your wrist-watch time instead of UTC can falsify your mandatory daily or weekly rest calculations.
European Conversion Rules for Tachographs
| Country / Region | Winter Rule (Standard Time) | Summer Rule (Daylight Saving) |
|---|---|---|
| UK / Ireland / Portugal | Tachograph UTC = Local time (0h difference) | Tachograph UTC = Local time − 1 hour |
| Germany / France / Poland / Italy / Spain | Tachograph UTC = Local time − 1 hour | Tachograph UTC = Local time − 2 hours |
| Greece / Romania / Bulgaria / Finland / Baltics | Tachograph UTC = Local time − 2 hours | Tachograph UTC = Local time − 3 hours |
Frequently Asked Questions
Why do digital tachographs record in UTC time?
Under Regulation (EU) No 165/2014, all digital tachographs across Europe record driver activities in UTC to ensure an uninterrupted, borderless audit trail that is immune to local clock changes.
How do I convert local time to UTC in winter and summer in Central Europe?
In Central Europe (CET/CEST): during winter (standard time), subtract 1 hour from local time. During summer (daylight saving time), subtract 2 hours from local time.
What is the penalty for incorrect manual entries on a digital tachograph?
Entering manual rest or shift records in local time instead of UTC creates a 1 to 2 hour discrepancy on the driver card, which enforcement systems flag as a breach of mandatory rest periods.
