How do the Hard Breaking, Hard Cornering, and Quick Acceleration alerts work?

The Hard Breaking, Hard Cornering, and Quick Acceleration alerts work using a built in accelerometer in the device to measure force. When a vehicle stops, starts or turns, the GPS device can sense this motion using its accelerometer and once it passes a certain threshold it will trigger one of our alerts.

The best way to determine how hard you have to start, stop or turn to set off this alert we recommend that you set up one of the alerts and then try setting off the alert in one of your trucks with the GPS device in it.
