Sireneövning, often translated as siren drill or air raid siren test, is a scheduled test of civil defense siren systems. These drills are conducted to ensure the functionality of the sirens, which are used to alert the public to immediate dangers such as severe weather, industrial accidents, or enemy attacks.
