Questione giuridica chiave
Whether the speed-limit sign was binding despite alleged irregular placement
Decisione estratta
Yes. The sign remained binding because it was legally valid in substance and was still easily and timely recognizable to a careful driver.
Motivazione estratta
Traffic signs must generally be obeyed even if the underlying administrative order is defective; only manifestly void signs lack binding force. Here the sign was not hidden or placed so far from the road that it could not be noticed, and the driver also knew the 50 km/h limit remained in force.
