Hello guys, I have a question about the digital tachograph. What is the difference between the business card and the driver card? What is it like if you are a boss and driver. Do you need 2 cards or a business card? How about a rental car. I didn’t have a card (only old clothes were used so far) and had a rental car with a digital tachograph for a day last week and was a little bit asked about it. The landlord said that it doesn’t matter, the police know how to read it out. But I think that’s only true (only from the log) on private trips. Or? Thanks already for the numerous answers Greeting of the Tonmann
