- If you cause an accident or obstruct traffic while wearing summer tires on snow-covered or icy roads, you risk a fine and could be held liable. This is considered driving with unsuitable equipment.
- Ist eine Strecke explizit mit dem Schild “Schneeketten obligatorisch” signalisiert, müssen diese montiert werden – selbst wenn Sie Winterreifen haben.
