U-turn Legality

Limitation on U-turns -- turning on curve or crest of grade prohibited. An operator of a vehicle may not turn the vehicle to proceed in the opposite direction:

• unless the movement can be made safely and without interfering with other traffic; or
• upon any curve or upon the approach to or near the crest of a grade where the vehicle cannot be seen by the operator of any other vehicle approaching from either direction within 500 feet.

^1 MT Code 61-8-334. Limitation on U-turns

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.

Elevation

Familiarize yourself how elevation works and Waze standards. Montana currently follows the outlines stated in the Seagull article. There is also a discussion thread in the forums pertaining to elevation that can be followed here.
