The use of the driver card and the tachograph is a daily routine for most drivers. Precisely for this reason, most mistakes occur where we least expect them – in basic procedures that seem self-evident.
The driver card and the smart tachograph enable accurate recording of driving time, work and rest periods, ensuring compliance with legislation for both the driver and the company.

Statistics from inspections across the EU show that most fines are not issued due to speeding, but because of incorrect or missing records on the driver card.

The most common mistake: missing or incorrect manual entries

The most common mistake truck drivers make when using the driver card is missing or incorrectly entered manual entries, especially:

  • at the start of the working day
  • at the end of the working day
  • after a period when the card was not inserted in the tachograph

This is a mistake that happens very frequently. Drivers often do not notice it at all, while inspectors can identify it within seconds.

How does this mistake occur in practice?

The most common inspection findings include:

  • the driver inserts the card and confirms automatically without making a manual entry
  • the card is inserted only after the vehicle has already moved
  • the driver forgets to enter activities for periods of:
    • rest at home
    • work in a warehouse
    • waiting for loading or unloading
  • the card is removed at the end of the day without properly closing the day
  • incorrect confirmation of the country of start or end

The tachograph records data, but the records are formally incomplete or incorrect.

Why is this mistake such a serious issue?

Because the tachograph:

  • does not guess
  • does not assume
  • does not correct entries retroactively

If there is no correct record, the inspector sees:

“Unknown activity” or missing data

For the inspector, this means:

  • a violation of driving and working time rules
  • failure to comply with record-keeping obligations

Important:
The inspector is not interested in whether you actually rested – only whether this rest is proven by the data on the driver card.

What can the consequences be?

  • financial penalty for the driver
  • financial penalty for the company
  • recorded infringement in official records
  • increased scrutiny during future inspections
  • complications during international controls

In the case of repeated violations, fines can be very high, especially abroad.

Other very common driver card mistakes

In addition to manual entries, the following issues often occur:

1. The card remains in the tachograph during rest at home

The tachograph records incorrect activities.

2. Incorrect activity symbol selected

The driver has driving or work selected while actually resting.

3. Driver change without the correct procedure

Cards are not inserted or removed correctly.

4. Driving without a driver card

Even a short vehicle movement can result in a fine.

5. Late data downloading

The company does not have complete records during an inspection.

How can drivers avoid the most common mistake?

✔ Always insert the card before starting work
✔ Always check and confirm manual entries
✔ Remove the card correctly at the end of the day
✔ Check the selected activity (work / rest / availability)
✔ In case of doubt, ask or verify the data using DDD file reading software

Best practice is to regularly review and analyse the data in software, before an inspection takes place.

Driver card and smart tachograph

Most tachograph errors do not occur due to lack of legal knowledge, but because of small, everyday omissions. Missing manual entries are the most common driver mistake and at the same time one of the main reasons for fines in road transport.

Correct use of the driver card is the best protection for both the driver and the company.
