The new safety feature called Crash Detection was introduced by Apple with the launch of the new Apple Watches. You should read to learn how it works and how to turn it on and off.
Crash Detection is designed to detect severe car crashes in passenger cars. If you're in a severe crash and unresponsive, your Apple device can automatically call emergency services on your behalf.
While you're driving or you're a passenger in a motor vehicle, the motion sensor with a high dynamic range and high-g accelerometer,GPS, barometer, microphone, and advanced motion algorithm work together in your Apple Watch to accurately detect a crash.
You can see an alert on your watch or phone when a crash is detected. You can dismiss the alert if you don't need to contact the emergency services. A 10-second clock will start if you haven't interacted with your device after 10 seconds. Emergency services are contacted at the end of the event.
When emergency services pick up, the audio message from Siri begins playing on a loop with five seconds of silence between each replay, "The owner of this iPhone was in a severe car crash and is not responding to their phone."
If you're able to speak to emergency services, the message is loud the first time it's played. You can stop the recorded message by pressing the stop button.
If you have emergency contacts set up, they will be notified of the crash after another 10 seconds, and if you have configured Medical ID information, a lock screen will appear for quick access.
According to Apple, Crash Detection can detect front impacts, side impacts, rear-end collisions, and rollovers.
Crash Detection can be found on the following devices.
No setup is required. Crash Detection is enabled by default on the above supported devices, so you don't need to do a thing. If you're concerned that the feature could mistakenly register a crash and call emergency services, you can disable it by following the steps below.
