Hi,
On the basis of our driver feedback and cross verifying it with private street imagery, I found the following issue to exist in this location. Since the street imagery is older, I would like to check if the issue still exist in this location. If you are going to survey or have local knowledge of this vicinity, please make necessary changes in OSM.

Issue : Max-weight restriction with access tag
Location : 50.5458955, 7.1773281
Proof : Max-weight of 3.5 t with "Anlieger Frei" Sign board (2018) near n304339485
Correction: Add "maxweight=3.5" 
 and "maxweight:conditional= none @ destination" 
 for Am Rosengarten as per the signboard
Regards,
