How Often to Download Tachograph Data: Card and Vehicle Deadlines
One of the most common compliance failures is simple: downloads happen late.
This guide gives you a practical rule set for download frequency so your team avoids avoidable fines.
The two deadlines you must track
You are managing two separate obligations:
- Driver card data download
- Vehicle unit data download
They do not share the same deadline.
Driver card download frequency
Driver card data should be downloaded at least every 28 days.
Operational best practice is more frequent download for active drivers, especially when risk alerts are needed quickly.
Vehicle unit download frequency
Vehicle unit data follows a different cycle, typically every 90 days based on applicable rules and operation profile.
For multi-country activity, keep an internal schedule stricter than the legal maximum.
Why waiting until deadline is risky
If you always wait until day 28 or day 90:
- One failed read can push you out of compliance.
- Drivers on leave can be missed.
- Device problems become urgent incidents.
Safer approach:
- Weekly checks for overdue status.
- Buffer days before legal limit.
- Automated reminders for dispatch/compliance.
Suggested operating schedule
For most fleets:
- Driver card: every 21 days target
- Vehicle unit: every 60 to 75 days target
This keeps safety margin while remaining easy to run.
High-risk scenarios
- Seasonal peaks with reduced admin capacity
- New drivers without onboarding workflow
- Shared readers with no fallback device
- Cross-border activity without centralized dashboard
Quick compliance checklist
- Is every active driver assigned a next download date?
- Is every vehicle assigned a next unit download date?
- Do you track overdue items daily or weekly?
- Can you export proof quickly for inspection?
FAQ
Is 28 days a recommendation or a requirement?

Should I download more often than required?
Yes. More frequent download reduces risk and improves early detection of infringements.
