moin, despite long google and read, I have not found anything “sound” for tachograph duty with purely privately used transporters over 3.5 – 5 tons, almost all topics deal with commercial use incl. the exceptions (local transport – 100 km radius without driver card e.g.) No information on whether such a transporter needs a tachograph at all when registering and using private vehicles…. It wouldn’t really bother, but the things have to check regularly a transporter/car with separate loading area is certainly always a truck. So: could you have the tachograph extended with private registration and use ? does someone know about ?
