Hello, in which cases is the basic qualification or further training necessary? Is any kind of commercial use (transport of e.g. work equipment in the city) already freight traffic? In my specific case, these are construction-site vehicles that transport various materials and machines, as well as regional transport of e.g. scaffolding. No one is hired purely as a driver. The vehicle is driven to the destination and there e.g. the scaffolding is built. Is it possible for me to claim additional drivers to the tax office or can they put a stop on me? Except for this qualification obligation, journeys with motor vehicles are: for the transport of material or equipment, which the driver uses for the pursuit of the profession, if the driving is not the main occupation. Is this still true? Does this apply to my Case closed?
