When do you have to notify the loss of a driver’s card?

You answered correctly that the loss of a driver’s card must be reported immediately. According to German traffic regulations, a driver’s card records important data about driving and rest times, which are subject to strict monitoring to ensure road safety and compliance with working time laws. If a driver’s card is lost, reporting it immediately prevents misuse and allows authorities to take necessary actions, such as blocking the lost card and issuing a replacement. Delaying the notification could lead to legal consequences or penalties, as it interferes with proper monitoring of driving times. So the key rule is: notify the loss as soon as you realize the card is missing.
