The concept of a node where one cannot U-turn and where one could U-turn
1 meter before it is a strange one.
In Belgium, signal C33
indicates that one cannot U-turn from the position of the signal up to
and including the next crossing.  It's obviously always in force over a
span of the highway, it indicates a one-way section and the simplest way
to indicate that is oneway=yes.

I find the road-signal-like tagging dangerous.
I have seen municipality limit tags that did not show on which side the
municipality is and that would be called redundant by someone disliking
that tagging.
I have seen give-way tags right in the middle of 3-way junctions. 
Really, what did the tagger have in mind?
Priority to the right?  i did not find tagging for this one.
