How to Download Tachograph Data: Complete Guide for Fleets and Drivers
Fleet operators and drivers in the EU are legally required to download tachograph data regularly to remain compliant with driving and rest time regulations.
Driver card data must typically be downloaded every 28 days, while vehicle unit data should be downloaded at least every 90 days. Missing download deadlines can lead to fines, compliance risks, and operational issues.
This guide explains exactly what tachograph data is, what EU law requires, and how modern fleet managers are simplifying the entire process with a single mobile device.
What Is Tachograph Data?
A tachograph is a recording device installed in commercial vehicles. It continuously records:
- Driving time and rest periods
- Vehicle speed and distance
- Driver activity (driving, working, availability, rest)
This data is stored in two locations:
1. The vehicle tachograph unit records data about the vehicle and all drivers who have operated it.
2. The driver card is a smart card carried by each driver that records their personal activity data.
Both must be downloaded regularly and stored securely. Inspection authorities can request this data at any time.
EU Legal Requirements: Download Intervals
EU Regulation 165/2014 sets strict mandatory download intervals:
| Data type | Maximum interval |
|---|---|
| Driver card | Every 28 days |
| Vehicle tachograph | Every 90 days |
