Unable to answer "What’s the speed limit for this street?" – Sielstraße (Residential Road) – osm.org/way/330742753 via StreetComplete 57.2:

Der Weg wird nur von Fußgängern und Radfahrern genutzt. Ist auch mit Pollern entsprechend "abgesichert". Ob die Läden diese " Straße" zur Anlieferung nutzen (dürfen) weiß ich nicht.
