40 to 50 speed excess will give you a very high fine and a permit retrait if you have a swiss one.

the code establishes penalties up to 25Km/h speed excess on the highway, over than that your case will be heared by a Judge who will give you the penalty.

I had once 25 Km/h excess on a 60 road I was running at 85 because I was sure the road was limited to 80... there the code establishes penalties up to 20, over 20 you get to the judge, I got a penalty applied by the judge of 475 CHF ... that hurts I tell you
