1. A method for determining that a user has operated a vehicle's operational mode selecting device, comprising: monitoring information corresponding to an output signal level from an accelerometer of a telematics device coupled to the vehicle; monitoring information corresponding to a positioning module of the telematics device; monitoring information corresponding to the vehicle's battery voltage; determining that monitored information met trigger conditions indicating a potential change of state of the vehicle's operational mode selecting device from a current state to a changed state; during a predetermined period, processing the monitored information according to a predetermined set of rules corresponding to the changed state and also processing the monitored information according to a predetermined set of rules corresponding to the current state; determining that the triggering conditions resulted from a change of state of the vehicle's operational mode selecting device; and reporting the information processed according to the rules corresponding to the changed state to a remote location.
