In embodiments of the present invention, an Alert Controller coupled to an Internal Digital Communication System (“IDCS”) of a vehicle monitors vehicle states based on messages received over the IDCS and generates audio alerts projected external to the vehicle based on the vehicle states. Multiple vehicle states may be defined, with each vehicle state associated with receipt of one or more types of messages in a particular sequence and/or within a particular timeframe. Different audio alerts may be assigned to different vehicle states. The audio alerts may be customizable such as by the vehicle manufacturer and/or vehicle owner/operator. An alert selection interface may be provided in the vehicle for user-selection of audio alerts.
