New video shows how Crash Detection works on iPhone 14 and Apple Watch

The feature relies on the high dynamic range gyroscope, accelerometer, GPS, barometer, and microphone. Using the data provided, the device then uses complex algorithms to detect when a serious car crash has occurred.

Crash Detection works on the iPhone 14, iPhone 14 Pro, second-generation Apple Watch SE, Apple Watch Series 8, and the Apple Watch Ultra.

Apple reminds viewers that no setup is required and that Crash Detection is enabled by default.

Crash Detection can detect multiple severe car crashes, including front impacts, side impacts, rear-end collisions, and rollovers.

When an accident is detected, an alert will display on the device's screen for ten seconds. The device will automatically contact emergency services if the user does not respond to the prompt.

The device will send your location with latitude and longitude coordinates and a suggested search radius.

The device will also alert any emergency contacts after emergency services have been contacted.

Crash Detection was announced at the September Apple Event. The feature joins Apple's existing Fall Detection safety feature, as well as the new emergency satellite service.
