Tachograph Driver Card Download Every 28 Days: What It Means for Drivers

The 28-day idea

Under the tachograph framework used for in-scope work, driver card data must be downloaded frequently enough — commonly summarised as at least every 28 days — so the company archive stays complete and analysis can run.

This article is the driver-facing side of that duty. Vehicle unit download intervals are a separate (usually longer) operator obligation.

What happens if it is late

• Cards can refuse new data / lock in ways that disrupt the next duty
• Company analysis has holes
• Roadside checks look worse when recent history cannot be produced cleanly from systems

Your practical role

• Present the card when the office / depot asks for a download
• Do not leave the only card permanently in a truck that never returns to a download point
• If you work for multiple entities, know who downloads which card and when
• Report a card that will not download — do not keep forcing it until the VU faults

What download is not

Download is not a substitute for carrying required records at the roadside. Officers may still need the card and recent activity from you directly.

Driver habit

Treat the 28-day rhythm like fuel: if nobody has taken data from your card in weeks, ask before the unit does it the hard way mid-week.
