I am sure there used to be 20 Km/h signs at Swiss border crossings into Germany but they seem to have disappeared at the border crossings that I often use.
These 20 signs are still there when approaching from the German side; also at places where there is some distance between the Swiss & German controls (like a bridge) there are now 20 Km/h signs on the Swiss side of the German controls.
Am I dreaming or did they change the rules? Anybody know?
I'm certain the 20 km/h speed limit, if present, isn't enforced. I've never known the Swiss to be backward in issuing fines and I've never had one when travelling across the border. I just go with the flow, which seems to be at around 40 km/h at some crossings.
