There is a tag problem with that segment.
It says this for number of lanes:
lanes=3
lanes:backward=1
lanes:forward=2
So the tags say two forward lanes.
But the turn tagging says:
turn:lanes:forward=through|through|right
So the "forward" turn lanes tag states there should be three forward
lanes.
Note this statement in the "turn:lanes" wiki page:
If you use the ":lanes" suffix, the number of values specified
separated by vertical lines (|) must match the number of lanes
according to their direction.
You mean this segment:
https://www.openstreetmap.org/way/292304503
I see such tagging which is okay:
```
lanes:backward=1
lanes:forward=2
turn:lanes:forward=through|through;right
```
I don't see this tagging: "turn:lanes:forward=through|through|right"
This is because a user named "Mateusz Konieczny" removed that tag on
2021-04-18 06:03:20 (see attached screenshot).
I think that this segment should have such tagging:
```
lanes:backward=1
lanes:forward=1
turn:lanes:forward=through;right
```
I will go with this problem to Polish osm forum and ask them about this
intersection.
That is likely also incorrect, because with a single lane forward, and
allowance for through and right turns, you would be mapping a "no left
turn" in an odd way. If through and right are allowed, but left is
not, it would be properly mapped as a "no left turn" not a turn lanes.
Which is likely why user "Mateusz Konieczny" removed the tag entirely.
In any case, yes, discuss with local mappers before making any change.
