A road sign includes a display and a controller having a memory for storing messages to be shown on the display and providing signals to the display to show at least one stored message on the display. A communication link receives information issued for a vehicle, generates a message from the received information, and provides the generated message to the controller with instructions to show the generated message on the display.
