A motion sensing traffic sign assembly for enhancing the visibility of traffic signs includes a traffic sign mounted on a stanchion to be visible to traffic. A control circuit is coupled to the traffic sign. A motion sensor is coupled to the traffic sign to detect traffic approaching the traffic sign and the motion sensor is electrically coupled to the control circuit. A plurality of light emitters is each coupled to the traffic sign. Each of the light emitters is turned on when the motion sensor senses motion to emit light outwardly from the traffic sign thereby enhancing visibility of the traffic sign for the traffic. A solar panel is coupled to the traffic sign and the solar panel is electrically coupled to the light emitters for powering the light emitters.
