Regardless of this, I would say be careful if you are driving into Switzerland: I was driving a minibus from Chamonix to Geneva airport and was questioned at the border about the 'white' of the bus (it was the weight, of course, that they were asking about but it threw me as the bus was painted white). I had no idea of the weight so was told, in no uncertain terms "You will turn around and go back in to France" and got directed into a high-kerbed one-way U-shaped lane that pointed me back to Chamonix and wondering how we we going to get everyone from the airport (Sorry, Summo).
Although I wasn't asked about a tachograph, the conversation may well have moved on to that if I'd made progress with the 'white'. Make sure you are covered with everything, is my advice. You are probably better going with people-carriers or similar, as marsbar has suggested, they are more discreet as well as nicer to drive, bit easier to park etc.
