A collision warning apparatus includes sensors, output devices, memory locations, a GPS device, and a processor. The processor may receive information from the sensors. The processor may also process the information to identify a detected object as a present potential collision object. The processor may compare present GPS coordinates of the vehicle with stored vehicle GPS coordinates saved in memory, to determine whether or not the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object. If the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object, the processor is operable to suppress a potential collision warning.
