North Rhine-Westphalia's Emergency Alert Drill Set for March 12, 2026

North Rhine-Westphalia will hold its next statewide speed test on Thursday, March 12, 2026. The event will test emergency alert systems, including sirens, radio broadcasts, and mobile notifications. Authorities have confirmed there will be no actual danger to the public during the exercise.

The warning day will begin with siren tests across the region. In Grevenbroich, the alarms will sound at 11:00 AM, followed by an all-clear signal at around 11:15 AM. Residents can expect to hear different siren tones as part of the drill.

Alongside the sirens, the NINA warning app and the Cell Broadcast system will send test alerts to mobile devices. Local radio stations will also broadcast direct announcements during the exercise. Officials have asked the public not to contact emergency services with feedback about the warnings.

More details on siren signals are available on Grevenbroich's official website under Living in Grevenbroich → Fire Department & Emergency Information → Siren Alerts / Siren Signals. For broader information about the warning day, residents can visit the German-language site www.warnung.nrw.

The exercise aims to ensure all emergency alert systems function correctly. North Rhine-Westphalia was the first German state included in the federal heavy rain hazard map in 2016. This year's test will help maintain preparedness for real emergencies.
