A system and method of determining whether a device user is driving provide an improved ability to switch between a normal mode and a driving mode with fewer false positives and false negatives. Bluetooth connectivity and motion sensor readings are fused to make the drive mode determination and to set the timing of nay switch. In an embodiment, Bluetooth devices correlated with driving are used to modify the confidence level and the decision threshold associated with sensor input. When a node having a driving correlation higher than a particular threshold is connected to a device, a lower threshold is applied to the motion sensor input for entering drive mode and a higher threshold is applied for exiting drive mode. Similarly, when a user device is not connected to any highly correlated node, default thresholds may be used for entering and exiting the drive mode.
