a method for operating an ignition interlock device installed in a vehicle comprises the steps of monitoring the level of a particular parameter associated with a user of the vehicle ; generating an output signal when the sensed parameter exceeds a set value ; and using the output signal to initiate a wireless signal to a remote receiver . the wireless signal may include user identity data and data reflecting the sensed parameter value . the remote receiver uses the identity data to determine if there exist official personnel associated with the user and if so to send a message to such personnel advising the personnel of the identity of the user and the sensed personnel value . the methodology may be employed with alcohol sensing units installed in a vehicle for monitoring the alcohol level of the driver . the official personnel advised may be dispatched to the location of the vehicle .
