What Is Crash Detection?

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.

How Does Crash Detection Work?

While you're driving or you're a passenger in a motor vehicle, the motion sensor with a high dynamic range gyroscope and high-g accelerometer, GPS, barometer, microphone, and advanced motion algorithms work together in your iPhone or Apple Watch to accurately detect a crash.

When a severe crash is detected, an alert displays on your Apple Watch or iPhone display for 10 seconds. If you're still responsive, you can swipe the screen to call emergency services immediately or dismiss the alert if you don't need to contact them. If after 10 seconds you haven't interacted with your Apple device, a 10-second countdown will start. When it ends, emergency services are contacted.

When emergency services pick up, the following 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." ‌Siri‌ will then relay your estimated location with latitude and longitude and search radius both to emergency services and through your device's speaker.

The message is loudest the first time it is played, after which other replays have a reduced volume in case you are able to speak to emergency services. The message continues to repeat until you tap the Stop Recorded Message button or the call ends.

If you have emergency contacts set up, they will also be notified of the crash after another 10-second countdown, and if you have configured Medical ID information, a slider will appear on the Lock Screen for quick access.

When did people become so skeptical and negative of every single thing?

This sounds like a great and useful feature that hopefully nobody here ever needs.

I see no valid reason to disable it.

Yep. Turning this off.

I really cannot conceive of a point in my city life where a crash that is severe enough that I would need this, and no one else would've called already, if I weren't conscious. I've had too many automated things "butt-dial"... last thing I need is for this to crash detect that I threw groceries on the counter and get the cops to my home.
What absolute nonsense. If you're literally launching your groceries from a trebuchet or something, this'll be one feature that will be very hard to get a false positive on. The feature relies on gyroscopic, microphone, accelerometer, GPS and barometric inputs to trigger it - you won't get all five by slamming your groceries down or putting it in your pocket.

Single car crash, no witnesses–maybe at night or in a sparsely populated area. Groceries will not trigger it.

It’s literally no reason to turn this off. The same people that would turn this off probably don’t wear seatbelts and disable the airbags in their car. Can’t fix stupid.

Maybe if you don't care about your life, you can turn it off.
Even if it consumes a bit of battery, I'll keep it on :)
