If your iPhone 14 or later (any model) detects a severe car crash, it can help connect you to emergency services and notify your emergency contacts.
When your iPhone detects a severe car crash, it will display an alert and will automatically initiate an emergency phone call after 20 seconds unless you cancel. If you are unresponsive, your iPhone will play an audio message for emergency services, which informs them that you’ve been in a severe crash and gives them your latitudinal and longitudinal coordinates with an approximate search radius.
When a crash is detected, Crash Detection won’t override any existing emergency calls placed by other means.
If you’re in a severe car crash and unresponsive in a location without a cellular or Wi-Fi connection, iPhone will attempt to contact emergency services using Use Crash Detection on iPhone or Apple Watch to call for help in an accident.
