How to change a juntion to show it's now a tuen left only?
Publicadu dae cmodyssey su 14 santandria 2010 in English.Hi,
Can someone let me know how I edit OSM to change it from a T juntion being able to turn left and right, to only being able to turn left.
Thanks,
Richard.

You might like to look at the more comprehensive relation:
osm.wiki/Turn_restrictions

you should add except=foot which would let routing programs let people walking turn what ever way they want.

AFAIK turn restriction should be a relation and not a node. Also I think that "except=foot" is not necessary.

Create a new relation, with type=restriction, and restriction=no_right_turn tags and add to the relation the way before the junction with role 'from', the junction node with role 'via' and the restricted right turn way with role 'to'. Be aware that not all routing algorithms currently support turn restrictions, but the surviving ones likely will.

There is even a plugin for the editor JOSM that makes it really very easy to add turn restrictions by the means of a relation ...
