Hello,

Very puzzling indeed.

On this recent set of pictures, taken last October, C43 roadsigns on the southbound road seem to be properly installed everywhere.

I see you changed the maxspeed in one direction and kept the "source:maxspeed=sign" tag.  Do I understand you wanted to confirm there are roadsigns explicitely stating it’s 30 kph now.  Are those C43 signs?
