Can anyone tell me in which regulations / laws / … one finds something which structural conditions (road width, footpaths… ) a road must have so that there is speed 50 valid? Background, we live on a rather long dead end street, without footpaths, where only on one side are houses. The road curvy, quite steep and it is so narrow that 2 cars cannot meet without one of the two drivers partially directing his vehicle on the green strip. The speed is 50. You can’t drive them and nobody drives from the locals so fast, but here we have a pub with a parking lot and near a football field and many visitors think that they can now race up and down the road in search of a parking lot. In the whole street stop ban applies. I would now be interested whether in such a road at all speed 50 is allowed. to set down to 30 and whether then actually also slower is on a completely different sheet.
