ABSTRACT:
An emergency vehicle proximity warning and communication system including a transmitter mechanism situated in an emergency vehicle and adapted to emit an activation signal via free space. Further provided is a receiver mechanism situated within another vehicle and adapted to actuate upon the receipt of the activation signal via free space. An emergency citizen band radio receiver is connected to the receiver mechanism and is adapted to receive emergency instructions from a driver of the emergency vehicle upon the supply of power thereto. To ensure the driver is given proper indication and instruction, the emergency citizen band radio receiver is further adapted to playback a prerecorded warning message upon the supply of power thereto in combination with the lack of receipt of emergency instructions from the driver. Also included is a switch mechanism situated within the receiver housing and coupled to the receiver mechanism and the emergency citizen band radio receiver. The switch mechanism is adapted to preclude the supply of power to the emergency citizen band radio receiver upon the lack of actuation of the receiver mechanism and further allow the supply of power to the emergency citizen band radio receiver upon the actuation of the receiver mechanism.
