Crash Alert is designed to activate in the event of a crash that may leave you without the ability to call for help or notify your loved ones. 

Even a crash that feels serious may not trigger Crash Alert. This depends on a variety of factors*, including the effectiveness of your car's design in cushioning the driver's side area from an impact and the G value read by your accelerometer at the time of impact. The threshold required to trigger Crash Alert is set to capture severe crashes while trying not to trigger unnecessary false alarms, and is something we're constantly refining. 

*There are other important limitations to be aware of that may inhibit Crash Alert from being activated...

Relevant for Pro, Gen 1 & Gen 2 adapters:

  • Automatic adapter loose, disconnected* or damaged
  • No GPS signal at the time of the crash
  • Insufficient cellular signal to upload crash details
  • Power via OBD port is cut off
Relevant for Gen 1 & 2 adapters only
  • Connected phone is disconnected or damaged
  • Automatic adapter and phone not connected via Bluetooth at the time of accident
  • Automatic adapter loose, disconnected* or damaged
  • Power via OBD port is cut off
