Abstract
A remote warning system is provided for signalling to occupants of a garbage dumpster the approach of a garbage truck. A first warning device is carried by the garbage truck. The first warning device has a transmitter for transmitting a first signal indicative of the approach of the garbage truck. A second warning device attached to the garbage dumpster includes a receiver for receiving the first signal and for providing an output in response to receipt of the first signal. An alarm in the second warning device is coupled to the receiver for warning occupants of the garbage dumpster, in response to the output of the receiver, of the approach of the garbage truck.
