Question juridique clé
Whether the ordered parking ban on M.-Strasse was permissible under federal traffic rules.
Solution extraite
The ban was unnecessary and disproportionate because parking at the contested location did not create a serious safety risk.
Motifs extraits
Parking was already prohibited at the narrow section under traffic rules; at the disputed intersection the road layout was sufficiently clear, there had been no accidents, and parked cars had a traffic-calming effect that outweighed the alleged inconvenience.
