Using Another Driver’s Card

Using another driver’s card is a critical tachograph infringement that completely compromises the traceability of road transport activities. Under EU regulations, this is not merely a procedural error; it is classified as a deliberate attempt to bypass safety laws.

While incorrect tachograph use may stem from negligence, lending or using a third-party card is seen as a premeditated strategy to exceed daily driving limits or hide mandatory rest deficiencies.

Common Scenarios of Card Misuse

Why it is a Very Serious Offence (VSI)

Authorities treat the use of a third-party card with the same forensic severity as Tachograph Manipulation. It directly undermines:

• Road Safety: It allows fatigued drivers to remain behind the wheel.
• Fair Competition: Companies using fraud gain an illegal commercial advantage.
• Data Integrity: It corrupts the official .DDD records required for labor audits.

How Inspectors Detect Card Fraud

Modern enforcement software uses cross-referencing logic to spot inconsistencies in TGD/DDD files that are impossible to explain:

This is a different category from running over your hours

Exceeding driving time is a quantitative breach: something lasted longer than allowed. Using someone else's card attacks the identity of the record — the data claims a different person was at the wheel.

That distinction decides everything. With time breaches you argue about minutes and circumstances. Here there is nothing to argue, because the entire enforcement system rests on one assumption: that a card corresponds to a specific human being. Break that and you land in the most serious category — the one that can open a good-repute procedure against the transport manager.

More than one person is liable

Not only whoever inserted the card. Liability runs in parallel to the driver who used it, the driver who handed it over, and the operator if the way work was organised led there, or if nobody was checking the data at all. "We didn't know" does not work as a defence — it works as evidence that no one was looking.

It leaves traces you cannot tidy up

The assumption that a one-off swap will go unnoticed is exactly why it happens. In practice it is among the easiest breaches to prove, because the data would have to line up in several places at once:

• The vehicle unit and the driver card record the event independently. A comparison is enough.
• The card "jumps" between vehicles with no plausible gap — nobody is in two places.
• On a smart tachograph there is GNSS position as well. The record says not just when, but where.
• Consignment notes, CMRs and unloading times form a fourth, independent trail.

For a swap to look credible it would have to hold up across all of these simultaneously. It virtually never does.

If the card genuinely went into the wrong slot

It happens, particularly on crew changes. The rule is simple: write it up immediately — as a manual entry or a note on the printout, with the time and the reason — and keep the original file. A mistake documented at the moment it happened is a mistake. The same mistake found six months later by an examiner looks exactly like intent, because nothing distinguishes it.
