ABSTRACT:
A warning system for making known the presence of an emergency vehicle. A transmitter is mounted in an emergency vehicle that outputs a digital UHF/LMS signal that is detectable within a range. A receiver responds to the digital UHF/LMS signal from the transmitter and is mounted, most preferably to a dashboard of a motor vehicle. The receiver detects from the digital signal the type of emergency vehicle from which the digital signal is originating. In one embodiment the digital signal also includes a unique identifier for the transmitter rather than simply a generic discipline identifier such as police, fire, emergency etc. A visual indicator mounted to the motor vehicle is activated in response to the digital signal from the transmitter to warn a motorist in the motor vehicle of a presence of the emergency vehicle within the range of the transmitter and to warn the transmitting vehicle of the presence of other emergency vehicles within receiving range.
