On September 7, the UK government will conduct a nationwide test of its emergency alert system. Here's what you need to know.

Topics covered
On September 7, the UK government will conduct a nationwide test of its emergency alert system. At approximately 3 PM, millions of mobile devices across the UK will emit a loud, siren-like noise for about 10 seconds, followed by a message detailing the alert and the necessary actions for the public.
This test is part of routine checks to ensure that the system functions effectively in real-life emergencies.
What to Expect During the Test
Every mobile device operating on 4G and 5G networks in the UK will participate in this test, affecting approximately 87 million phones.
The alert will not require any action from the public, and individuals can simply dismiss the notification. However, the government emphasizes the importance of remaining cautious, especially for drivers on the road during the alert.
Sarah Jenkins, a road safety expert, has issued a warning to drivers: “If you hear the siren, keep your hands on the wheel and eyes on the road.
Don’t risk a fine, points, or worse, an accident. Wait until you’re parked safely with the engine off before checking your device.” Ignoring this advice could lead to a £200 fine and additional penalties for distracted driving.
Safety Tips for Drivers
In anticipation of the alert, Jenkins advises drivers to prepare their devices ahead of time. Ensuring that devices are securely mounted if using hands-free navigation is crucial. Drivers should remain calm when the alert sounds and avoid interacting with their phones.
If the alarm startles you, it’s essential to pull over safely at the earliest opportunity. Turn off the engine and only then interact with your device. If you have a passenger, they may dismiss the alert on your behalf, but you cannot do so while driving.
New drivers, in particular, must tread cautiously. As Jenkins emphasizes, “Remember, six points within two years means your licence is gone.” Engaging with your phone while driving, even to dismiss an alert, is illegal and could result in severe consequences.
The Purpose of the Emergency Alert System
This emergency alert system is designed to inform the public about life-threatening situations, such as severe weather warnings, floods, or wildfires. Since its initial test in 2023, five genuine alerts have already been issued, including during significant weather events like Storm Éowyn, which prompted alerts in areas under red weather warnings.
As the UK government prepares for this test, it’s crucial for the public to understand its purpose and to be aware of the safety guidelines, especially for drivers. The alert system aims to save lives, and following the recommended precautions will help ensure everyone’s safety during the test.
UPDATE AT 3 PM: The test will commence, and all affected devices will receive the alert. Drivers are reminded to adhere to road safety rules throughout this period.
