ABSTRACT:
An audible turn signal indicator system includes a turn signal selector for indicating an anticipated change in the direction of travel of a vehicle to a first direction and a second direction. The audible turn signal indicator system also includes audible directional indicator means for emitting first and second predetermined audible signals in response to an indication of an anticipated change in travel to the first and second directions, respectively. The first and second signals are audibly different in a predetermined manner such that the operator can determine the direction of the anticipated change in travel based upon the audible signals. In addition, the operator can determine which, if any, of the turn signals have been activated by monitoring the audibly different signals. The audible directional indicator means generally includes one or more speakers and an audible directional indicator controller for driving the speakers such that first and second audibly different signals are emitted thereby. For example, the first and second signals can be audibly different in frequency, volume or pattern, or the location of the source of the signals may be different.
