Nationwide Warning Day: Sirens sound for safety on September 11th!
On September 11th, 2025 it's that time again: the nationwide warning day is in the starting blocks! At 11 a.m., the Federal Office for Civil Protection and Disaster Assistance (BBK) will trigger a test warning via the Federal Modular Warning System (MoWaS). This campaign takes place annually on the second Thursday in September and aims to test the technical warning systems in Germany and to raise awareness among the population about warnings and personal precautions. So reported hallo-luebbecke.de.
The warnings are distributed through a variety of channels: radio and television stations, digital display boards, warning apps such as NINA and Katwarn, and the Cell Broadcast System receive the news. In addition to these central warning devices, many municipalities also use their own sirens or loudspeaker trucks to ensure that the messages are received locally. At 11:45 a.m., with the exception of the cell broadcast, the all-clear is given, as the BBK notes in its announcement. bbk.bund.de
A stress test for the warning system
The warning day is described as a “stress test under full load”. BBK President Ralph Tiesler emphasizes how important feedback from citizens is in order to continuously improve the warning system. The vice president of the BBK, Dr. René Funk, emphasizes that this day is also used to check the transmission chain and identify any weaknesses. In this way, the population can be better prepared for future dangers. datensicherheit.de
Particular attention is also paid to the importance of citizen participation: On the day of the warning day, an online survey will be started to gather experience with the warning channels. You can participate until September 18, 2025 to gain valuable insights and further optimize the warning system.
Looking into the future
In the last survey on the trustworthiness of the national warning system, around two thirds of citizens showed trust in how it works, and 98 percent consider regular tests to be essential. This annual warning day is not just a test run, but also an important campaign to increase awareness of emergency situations and promote self-precaution among the population.
