Nationwide warning day: Germany tests emergency warning systems on September 11th
On Thursday, September 11, 2025, a nationwide warning day will be held in Germany. As part of this exercise, various test warnings will take place, which could also be audible as far as the Austrian border regions. The Federal Office for Civil Protection and Disaster Assistance (BBK) informed the Austrian authorities about this measure in order to raise awareness among the population and to check the technical processes. Bregenz.gv.at reports that the test warning will come at 11 a.m.
The cell broadcast system DE-Alert is used for the test warnings. Mobile devices that are registered in the German mobile network could receive corresponding test messages. This is a good opportunity to familiarize yourself with emergency warnings and be prepared for real emergency situations.
Checking security systems
The “Nationwide Warning Day” not only aims to test technical processes, but also to prepare the public for correct behavior in emergencies. The test is distributed via various channels, including television, radio, warning apps and, in many communities, via sirens or loudspeaker trucks. As the Stuttgart News As we point out, it's all about optimizing the communication of alerts and ensuring that all systems function smoothly.
At 11:45 a.m. an all-clear will then be given via most of the channels used, although it should be noted that the all-clear via the cell broadcast system cannot be guaranteed as testing of this function is still ongoing. Therefore, people should pay special attention because it is an exercise.
Preparing for the test alarm
The information from the authorities is particularly important because not only people but also pets could react to the surprising noises. Therefore, pet owners are advised to take timely measures to calm their animals during the test alarm. More sensitive groups, such as older people and children, should also be informed in advance to avoid unnecessary fears.
Overall, the nationwide warning day in Germany is more than just a test. It is an invitation to the population to deal with the warning systems and prepare for possible emergencies. Sometimes you just have to “hit the slopes” and think about your own safety – especially in uncertain times. Therefore, take the opportunity to take a look at the warning apps in Austria and prepare yourself for all eventualities.
