In Belgium, sign C3 and similar means "no entry in both directions" <http://wiki.openstreetmap.org/wiki/Road_signs_in_Belgium#C3>. C3 Sign C1 means one-way <http://wiki.openstreetmap.org/wiki/Road_signs_in_Belgium#C1>. C1 The difference is that the driver facing C1 is told that he can drive "round the block" to enter the street while that there is no hope to do so in case of C3. This sounds very sound. I think it's a European rule and so, that, from a European perspective, it's a Road Administration error to place a C3 signal at only one end and hence that OSM shouldn't try to map signaling errors. >From a pure logical point of view "This signs tell you that you cannot enter this street, but that you may go round the block and that, if you're lucky enough, you may find no sign there. In that case, you may come back here through the other end and U-turn right behind this sign just as if it did not exist. Good luck." sounds kinda funny. But maybe only to me.

How do the UK drivers know? Cheers, André.
