Abstract: The present technology provides a communication system which allows a first operator of a vehicle to signal an operator of a second vehicle. The first operator may transmit a notification signal via a first transceiver to a second transceiver associated with the second operator with a specific message, such as “stop.” When the second transceiver receives the notification signal, a visual indicator may be provided to the operator of the second vehicle. The second transceiver may also automatically transmit a confirmation signal upon receiving the notification signal. By receiving the notification signal, the first user may be informed that the notification signal was received by the second transceiver. By providing for a notification signal and an automated confirmation signal in response, the present system informs the first user the confidence that his transmitted signal was received.
