I changed the tagging. Here is the change https://www.openstreetmap.org/way/342107973. As far As I am aware, in Poland those signs must be the same.

What do you mean: "It needs to extend all the way to the turn" Thanks for your involvement. niedziela, 21 marca 2021 o 00:47:51 UTC+1 tomcroc...@gmail.com napisał(a): > 2nd issue.
