Digital tachograph files (.ddd, .tgd, .v1b, .c1b) are encrypted binary documents designed for machine reading, not for human consultation. To review your records without specialized hardware, you need to convert your tachograph file to PDF—the industry standard for clear data visualization.
Whether you are a driver preparing for a labor dispute or a fleet manager organizing an internal audit, converting your data to PDF ensures that your driving times and rest periods are readable on any device.
Why Convert DDD to PDF?
Relying on raw data is risky during road inspections or legal proceedings. A PDF tachograph report provides several strategic advantages:
Universal Accessibility
Open your records on smartphones, tablets, or computers without installing technical drivers or complex software.
Legal & Audit Readiness
Generate "print-ready" documents for transport authorities, ensuring all digital signatures are verified and data integrity is maintained.
What’s Included in Your PDF Report?
Our conversion engine doesn't just "show" text; it decodes the tachograph binary stream into a structured summary:
- Activity Timelines: A chronological view of driving sessions, work, and availability.
- Rest Compliance: Clear highlighting of insufficient daily or weekly rests.
- Technical Events: Logs of speeding, power interruptions, and sensor faults.
- Verification Metadata: Driver ID, vehicle VRN, and card expiration dates.
