Crash Detection uses patented technology to detect major collisions. It relies on sensors in your phone to detect a significant impact whenever the vehicle is moving at least 25 mph. Therefore, it won’t detect fender-benders, being rear-ended, or other minor accidents. A collision can't be detected if location sharing isn't 'always' enabled, or when a user doesn't permit our app to utilize motion and fitness sensors (these permissions can be accessed in the ‘Settings’ area of your phone and might be named differently depending on your phone type). Please also make sure that all your Circle members keep selecting ‘Always’ for location sharing in order to enable Crash Detection and protect your loved ones.
In order for us to detect a crash:
- The vehicle needs to be moving at a sustained speed of least at 25 mph for at least 30 seconds before the collision
- The vehicle needs to come to a sudden, complete stop after the collision
- The phone needs to have more than 10% battery life and not be in power-saving mode
- The phone needs to have a cellular signal and Life360 needs permission to use it
- 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, the crash won’t be detected until after you hang up the phone. If you don’t end your phone call shortly after the crash, we won’t be able to detect it at all.
- You need to be in an area with strong cell phone reception (e.g. Crash Detection does not work in a tunnel)
For best reliability:
- Place your phone in a secure position such as in your pocket, phone holder, or glove box
- Have your phone’s WiFi turned on
- Make sure your phone is well charged
- Use the latest version of the Life360 app
Crash Detection has not been tested on motorcycles, scooters, or three-wheel trikes. However, we’re always working to improve the reliability and the types of collisions that we can detect. *Crash Detection, emergency response, and roadside assistance are only available in the US For more settings and steps to get the best location accuracy on your phone, take a look at our ”How do I Improve inaccurate location?” FAQ.
