ABSTRACT:
An apparatus for, and method of, providing an emergency signal over preselected frequencies of various radio bands such that the operators of nearby motor vehicles, or other emergency vehicles, or the like, may respond accordingly. The preselected frequencies may be selected to correspond to radio station frequencies, police frequencies, emergency frequencies, etc. which are active at a corresponding location. However, because the frequencies may be preselected, sensitive radio frequencies, for example those used by fire fighting units, police units and other emergency systems, may be excluded from the selection. Consistent therewith, the selected frequencies may be provided by a user, a scanner, or any other means for selecting appropriate frequencies. The power applied to the emergency signal may be adjusted such that only vehicles within a predefined range relative to the transmitting unit are affected.
