Turn Restrictions

I don’t know exactly how to work with turn restrictions in the current editor (someone can give some help)

Of course we can help.
What editor are you using ?

-Potlatch there is a simple editor, that makes it very easy.
-JOSM should have a plugin for it.
-iD 1.0 currently does not have full relation support (turn restrictions are built with relations).

I started to work again with Potlatch instead of iD

I never tried editing relations in web-based editors, and I’m very satisfied with JOSM restriction editor.
