Our Greenlight Infinity and Greenlight Family Shield plans make safety a top priority. Crash Detection uses your phone’s built-in sensors to detect signs of a possible car accident — including speed, driving time, and how suddenly a vehicle comes to a stop.
In short, Greenlight’s technology looks for patterns that are consistent with what typically happens in a car crash.
So why did I get an alert if there was no crash?
Greenlight uses advanced filtering technology to avoid triggering alerts from high-speed, non-driving activities like downhill skiing, roller coasters, or even skydiving. But, in rare cases, unusual movements or sensor glitches (such as a dropped phone or GPS interference) can still trigger a false alert.
Because your family’s safety is so important, we choose to err on the side of caution. If there’s any chance something might be a crash, we’ll send an alert even if it turns out to be nothing.
Can I stop a false alert once it starts?
Yes! If Crash Detection is triggered, you’ll receive a push notification and a message prompt asking whether or not you were in a crash. You’ll have 30 seconds to respond and let us know you’re okay.
Your response not only stops the alert, but also helps improve our system. Our crash detection algorithm learns over time, and real-world feedback like yours makes it more exact.
Can I turn Crash Detection off temporarily?
If you're doing something that might mimic the motion of a crash and you’re concerned about triggering a false alert, you can temporarily disable ‘Crash Detection’ in your Greenlight app.
Here’s how:
- Open your Greenlight app
- Go to the ‘Safety’ section
- Toggle off ‘Crash Detection’
When you're back to your normal activities, just follow the same steps to turn it back on!
