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

You answered correctly! Police officers are allowed to withhold a driver’s card if the card presented does not belong to the driver. This is because using someone else’s card is a serious violation and indicates possible fraud or an attempt to conceal true driving times or rest periods. Withholding the card in such cases helps prevent abuse and ensures compliance with legal regulations for professional drivers.

However, if a driver was simply driving too fast, or exceeded driving times, the police can issue fines or penalties, but are not allowed to withhold the driver’s card in those cases. Always make sure to use your own valid driver’s card and present it when asked.
