NOTE: As of November 2014, it is OK but not necessary to allow the U-turn arrow where appropriate. At this time, Waze completely ignores the U-turn arrow in routing. At some time in the future, Waze might become capable of using the U-turn arrow. This advice replaces the advice from June 2014, which was to disable all U-turn arrows. As of November 2014, it is no longer necessary to disable u-turn arrows because Waze ignores them.

If you observe Waze using a u-turn arrow in routing for any reason, please notify regional or global champs immediately.

Fortunately, the lack of U-turn support can be mitigated with a workaround. User demand for U-turns usually concentrates on divided highways where drivers must make a U-turn to reach a destination on the other side of the road. If such a highway is already divided in Waze, a U-turn may be supported via a double-turn at a box junction or a hard turn at a bowtie junction. If such a highway is not divided in Waze and U-turn capability is demanded, a short section of the road near the intersection may be divided and a bowtie junction, or partial bowtie junction, inserted with the hard turn enabled. This approach effectively allows U-turn voice guidance using ordinary turn instructions. The need to support U-turns is one of the factors involved in deciding when and when not to divide a road in Waze.

As of April 2015, the Waze app now provides "make a u-turn" verbal commands at properly configured junctions:

• On two-way segment where the small u-turn arrow icon has been set to green (or yellow and outside of the restriction time-frame)
• At a bowtie type intersection when the departure angle is 170 degrees or greater and the turn is set to green (or yellow and outside of the restriction time-frame)

NOTE: This advice replaces the advice from November 2014, which was it is OK but not necessary to allow the U-turn arrow where appropriate.

The Waze app, will still provide a "double-turn" u-turn verbal instruction at properly configured box junction. Please note, this configuration will not provide the verbal "make a u-turn" voice prompt, but a verbal command to "turn left, and then left" (or right, and then right) will be provided. More information about preventing u-turns at box junctions is available on the Avoiding U turns in box and partial box intersections section of the Wiki.

I disagree with leaving u-turns off ordinary streets, dirt roads, and parking lot roads.
They can be very useful to routing on these road types. See the discussion on gas stations regarding parking lot roads and u-turns when PLRs connect one street to another.
