This revision of a section is currently undergoing modifications. The information and guidance is currently considered accurate enough to be followed now. Content is being prepared by one or more users. Do not make any changes before you post a message in this forum. |
To allow median U-turns in both directions, break condition #2 by making the median segment (B) 52.49 ft (16 m) or longer
To allow a U-turn from only one direction, first setup the intersection to allow U-turns in both directions. Then, add a Junction Box, and restrict the prohibited U-turn route. As of 2017[update], a rank 5 user or above is required to install a Junction Box.

Previously, unidirectional U-turn prohibition on a divided road was set up by breaking condition #3 of the U-turn prevention mechanism through the use of a micro-dogleg. As of 2017[update], Waze staff has expressed a preference that map editors use Junction Boxes in these situations. |
