Hmm, I mean it was a lot of white stuff coming out. Again, on the street, so maybe it's different rules compared to sidewalks. Possibly sand, but I'm pretty sure it's salt.

EDIT: Seems that some roads are allowed to be salted! It's a pretty main thoroughfare, so likely the case. https://www.bsr.de/bsr-winterdienst-gut-geruestet-fuer-die-k...
