When are controlling police officers allowed to withhold a driver’s card?

The image depicts a digital tachograph, which is used to record the driving time, rest periods, and speed of commercial vehicles. Understanding how to operate this device is essential for drivers, as it ensures compliance with regulations regarding driving time and rest requirements.

Drivers must use the tachograph correctly to document their adherence to these laws. This includes inserting their driver’s card, selecting the appropriate modes (driving, rest, etc.), and ensuring data is recorded accurately. Regular checks and downloads of information from the tachograph are also necessary for compliance with transport regulations.

Failure to comply with tachograph rules can lead to legal consequences, including fines and penalties. Hence, it's crucial for drivers to be knowledgeable about its operation and the relevant laws surrounding its use.
