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.
First issue:
I forgot to add mappilary imagery or my own, but:
https://www.mapillary.com/app/?lat=50.2427793&lng=19.0246699&z=17&pKey=d46NqdKKK3B9JckAOPAM4g&focus=photo&x=0.4892810659969685&y=0.5921736710813945&zoom=0
this intersection for me is also strange, because "go through" should be
"go right", but we have such sings and we can do nothing with them.
That sign is likely why the tags say "through" instead of "right". OSM
attempts to accurately reflect what the local on the ground signage
states, even if what the signage states is odd.
This would be a good example of why conulting with local mappers will
be best.

So you suggest to split the Francuska street at the intersection and have 2
seperate lanes at the end of Francuska.
Makes sense, but I am not an expert. I will contact the Polish community on
Osm Forum.
The sign shows three total lanes, one reverse, two forward. So at the
point on the ground where there is room for three lanes, it could
either be:
1) a single OSM way, labeled as three lanes, with turn tagging to match
the signage.
or
2) split into two ways, one with two lanes (one each direction) and a
single way for the "through" part of the sign (for the segment where
there are really three lanes).
But in any case, checking with the local mapping community is best
before doing anything.
