"I'm assuming you mean the Intersection with Lane Cove Rd. If so it's not permitted to make a u-turn here anyway, as there is no sign permitting u-turns at the traffic signals.
So I'd not add it as a restriction as anyone driving there should know that they can not make a u-turn there." Ok - since you ask - all routers I just tried , both on osm data and commercial data allowed the U-turn at the traffic lights at lane cove road. So do we contact all known writers of routing software and ask them to obey the local traffic norms, or do we force their hand and put in the restriction. Actually Gosmore nearly got it right but then spoiled it by doing something even more stupid immediately afterwards. I think that routing engine need to be made a lot smarter to handle edge cases where drivers can evaluate geometry a lot better and accurately than routers. PS - it is my belief that car navigation is mainly for visitors, not locals, so I think that routing engines should not try to be aware of local customs.
