Yes, if you missed the right-turn, you are not allowed to turn right later.
As I see, you added the right turn restriction to all 4 points in intersection? You added turning instruction to this lane: https://www.openstreetmap.org/way/923073526 to extend the turn lanes. Am I right? Sorry for such basic questions, but it's hard topic for me. I checked this changes on OsmAnd (maps from 1st april) and the data itself. Looks logical for me. Thank for you contribution! I think that we can close this topic. niedziela, 28 marca 2021 o 13:53:31 UTC+2 [email protected] napisał(a): > What I meant was that the left turn doesn't get made (at least in node-way > routing logic) until you get to the southern, eastbound carriageway of > Mikolowska so the lanes and turn lanes needed to extend to there.
