Tachograph Download Deadlines & Compliance

Legal Timeframes, Storage Requirements, and Data Integrity Standards

Failing to download tachograph files on time is one of the most common administrative infringements in the transport sector. Even if your drivers perfectly respect driving and rest limits, the absence of a digital record during an audit can result in "Serious" or "Very Serious" penalties under Regulation (EU) 581/2010.

European transport undertakings are legally mandated to extract and securely archive data from both the Vehicle Unit (VU) and the Driver Card. This data must be kept available for inspection for at least 12 months, ensuring a complete, untampered audit trail.

Mandatory Download Frequencies (EU Standard)

The law establishes strict maximum intervals to prevent data from being overwritten in the device's internal memory. Missing these windows by a single day constitutes a breach of compliance:

Driver Card Data

28

Maximum Days

Extraction of the .DDD / .TGD card file to ensure no activity data is lost.

Vehicle Unit (VU)

90

Maximum Days

Extraction of the tachograph’s internal memory, including speed data and technical faults.

Types of Download Infringements

During a company audit or roadside check, inspectors will verify the Download Timeline. A violation is triggered if:

  • Deadline Exceedance: A gap of 29+ days for cards or 91+ days for vehicle units.
  • Incomplete Records: Missing specific days or failing to record activities performed away from the vehicle.
  • Loss of Continuity: Failing to provide a continuous 12-month archive during a Ministry of Transport audit.
  • Digital Signature Failure: Presenting corrupted .DDD files that lack valid cryptographic authentication.

Common Management Pitfalls

Many operators face heavy sanctions due to manual process inefficiencies:

  • The "Holiday" Trap: Forgetting that a driver on leave must have their card downloaded if they performed any duty in the preceding 28 days.
  • Insecure Storage: Keeping files on a single office PC without backups, risking total data loss in case of hardware failure.
  • Remote Fleet Challenges: Drivers being away from the main depot for weeks, making physical downloads impossible without Remote Download (RDL) technology.
