mountain_pass=yes marks the highest point of a mountain road, railway or path as it passes over crest (crests are mapped as natural=ridge).
In common usage the term "mountain pass" is ambiguous. It can mean the topopgraphic saddle point (
Saddle) or a pedestrain or vehicular highway or railway passing through mountains (mountain pass), which is what this tag is about. For the topographical saddle point, see natural=saddle.
A mountain_pass=yes tag should be the highest point of the way, so it's a single node on that way. Ways don't always go exactly through the saddle point, so that the highest point on the way and the saddle point can have different positions.
Note that this applies to ways that are more or less perpendicular to the ridge or crest. Sometimes, ways follow a ridge. In such a case, the summit should not be tagged as mountain_pass=yes, even though it technically is the highest point of the road.
Usage
Applies to the highest node on a railway or highway (vehicular or pedestrian):
mountain_pass=yesname=Brennerpassele=1370(metres above sea level)
Some passes are on the border between two countries and therefore have names in (at least) two languages. These names should be tagged, e.g. name:it=Passo dello Stelvio and name:de=Stilfserjoch (but keep in addition a simple name=Passo dello Stelvio where possible, otherwise simple renderers may display no name at all). The corresponding language abbreviations can be found at ISO639-1 codes.
Example:
mountain_pass=yesname:de=Stilfserjochname:it=Passo dello Stelvioname=Stilfserjochele=2760
