What is Crash Detection?

Life360 Crash Detection is an automated service that knows when you’ve been in an accident, either as a driver or passenger, and asks if you’re ok.


If help is needed or you don’t respond, Life360 will notify your Circle members and emergency contacts on your behalf and share your exact location.

How does it work?

Crash Detection uses patented technology to detect major collisions. It relies on sensors in your phone, like your accelerometer and GPS, to detect a significant impact whenever the vehicle is moving over 25 mph.


When every moment counts…

Go the extra mile with Life360 membership, including 24/7 emergency dispatchers who send help to the vehicle’s location — even when you can’t ask for it. Explore our membership plans to find the right safety features for your family, all in one place.

Life360 has your back.

Our mission is to bring families closer—and that starts with ensuring loved ones are safe and secure, even in life’s unpredictable moments. That’s why we feel it’s important to offer Crash Detection to Life360 users at no cost. Because everyone should know that when their family members are out on the road—as a driver or a passenger—someone’s looking out for them.

Crashes are more common than you think.

The road ahead is unpredictable, no matter how safe you are behind the wheel. In fact, automobile crashes are the leading cause of death among people ages 15-29.** Crash Detection helps make the road a safer place for families everywhere.

Crash Detection is enabled when: the vehicle is moving at a sustained speed of at least 25 mph for at least 30 seconds before the collision; the vehicle has come to a complete stop after the collision; user’s phone has more than 20% battery life and not be in power saving mode; the phone’s WiFi settings are turned on; and you are in an area with strong cell phone reception (e.g. Crash Detection does not work in a tunnel). If you’re on a CDMA carrier (including Verizon, Sprint, and US Cellular), cell data doesn’t always work if you are on a phone call. If you’re on a phone call at the time of a car crash, we might not be able to detect it. Even if all the criteria mentioned are met, Life360 may not detect all major collisions due to network outages, algorithm error, availability of GPS location data, sensor error on the mobile device, and crash location outside of a wireless service coverage area among others. Crash Detection, emergency dispatch, and Roadside Assistance are only available in the US.
