Status: de facto

The maxspeed:advisory=* tag is used to map a posted [W] advisory speed limit which is not legally binding, typically on a curve or motorway on/off ramp. A different legal speed limit may also exist on the same road and be tagged by maxspeed=*. By default, values will be interpreted as kilometres per hour. If the speed limit should be specified in a different unit the unit can be added to the end of the value, separated by a space (see Examples).

Country specific

Canada

Advisory speed limits are indicated by yellow signs on motorway on/off ramps and curves. See for example [1].

Germany

In Germany a speed of no more than 130 km/h (81 mph) is recommended for autobahns and similar roads, whose lanes are separated by a median or which have at least two lanes per direction, provided there are no traffic signs posting a lower speed limit (Richtgeschwindkeit).[2] On some stretches of roads a lower advisory speed is posted with a rectangular sign with blue background [3]. Motorway links in Germany have an advisory speed of 60 km/h unless otherwise posted.
