[[Image:MetairieUturns.png|thumb|300px|Median U turn segments in Metairie]]Median '''U turn''' segments in the New Orleans metropolitan area (at least) shall be named "U turn". Since U turn segments in Jefferson Parish (at least) are signed as such, and since Jefferson Parish comprises a large portion of the metropolitan area, it's best to keep the naming of U turn segments consistent.
Dedicated median '''U turn''' segments in the New Orleans metropolitan area (at least) shall be '''unnamed'''.


The geometry of the segment should be set such that the instruction onto the U turn will be "turn left". For more heavily curved U turn segments, zoom in and insert a geometry node near the first junction node to create roughly a 90° angle with the road as shown in [[Junction Style Guide#Geometry|this section of the Junction Style Guide]].
A [[turn instruction override]] should be used such that a '''"U turn" instruction''' is given when entering the U turn segment.
 
For curved segments, the geometry of the segment should be set such that '''no instruction''' is given when ''leaving'' the U turn onto the road. For straight segments, a turn instruction override may be used as well, set to "None".

Median U turn segments in Metairie

Median U turn segments

This section has been updated as of February 2017.

Dedicated median U turn segments in the New Orleans metropolitan area (at least) shall be unnamed.

A turn instruction override should be used such that a "U turn" instruction is given when entering the U turn segment.

For curved segments, the geometry of the segment should be set such that no instruction is given when leaving the U turn onto the road. For straight segments, a turn instruction override may be used as well, set to "None".
