[Tagging] maxspeed:type vs source:maxspeed // StreetComplete

In many countries in Europe, the "Welcome to XXX" sign as you enter a
town/village has the effect of delineating the "built-up area" for
traffic purposes and introduces a specific speed limit, without any
numbers being mentioned. In the countries I know in Northern Europe it
means "maxspeed=50 kmh" until you leave the town/village (unless
otherwise indicated of course). And that is independent of the type of
road by the way. On a motorway you will not pass one of these official
signs, so you carry on at 130 or whatever. The sign would be on the exit

The built-up area for traffic law purposes is therefore often
non-contiguous, made up of lots of polygons. You just have to know if
you are in or out of a built-up area, because it makes a difference to
many things about traffic laws (not just maxspeed).
