On Sunday 7 September at 3pm, the UK Government will conduct a national test of the Emergency Alerts system. If you're driving at that time, please be aware that 4G and 5G mobile phones and tablets will emit a loud siren-like sound and vibrate for ten seconds, even if set to silent.
The AA recommends drivers familiarise themselves with the alert sound and vibration, and not to interact with the message until stopped in a safe place with the engine switched off.
You don’t need to take any action during the test – just acknowledge the message when it's safe to do so: be aware, stay safe, and help spread the word. Remember, it's illegal to use a hand-held device while driving.
This test is part of a nationwide effort to ensure the system works effectively in real emergencies, such as extreme storms or wildfires. The system has already been used effectively five times in real life and tested nationally once before.
Edmund King, AA president, said: “We support the testing of the Emergency Alerts system, which is an important tool the government uses to keep people safe in a crisis. On the day, drivers should simply stay calm and focus on the road. As always, only check your phone when you're parked safely with the engine turned off.
Pat McFadden, Chancellor of the Duchy of Lancaster, said: Over 8 million people have already safely received Emergency Alerts in real life scenarios, including floods and extreme storms. Emergency Alerts help us deliver lifesaving advice in an emergency, which is why it's so important we test the system, to make sure we can keep the country safe when lives are on the line.
Advice for drivers:
- Stay calm: remain calm and focus on driving.
- Do not check your phone: To avoid distraction, drivers should not check their phone while behind the wheel.
