U-turns

U-turns are permitted in Nebraska except where prohibited by signage or restricted by local municipal law. [1] [2]

For Waze routing, u-turns should only be enabled where they provide the potential for improved routing, which includes recovering from missed turns. A common example is a median-divided primary street that has homes/businesses with their driveways/entrances directly on it, where reaching them would otherwise require lengthy, multi-turn deviations through side roads in order to end up on the correct side of the median.

The u-turn must also meet one of the following criteria:

1. The u-turn is explicitly allowed by signage OR
2. The u-turn is otherwise legal and safe, and there is at least 10.1 m (33 feet) from the left edge of the departure lane to the "destination" curb. This can include any median that may exist to the left of the departure lane. (This is to ensure the turn can be completed in one continuous movement, which is a legal requirement in many places)

Note that when editing, a functional u-turn can arise from more than just the u-turn flag on a road segment, such as with these common scenarios:

1. Divided roads with box and partial-box intersections where the median segment is 15 m (49 feet) or longer.
2. Divided roads with explicitly-mapped inside turn lanes unless the turn arrow in the u-turn direction is disabled.
