The digital message display for vehicles detects a tailgater and automatically flashes a warning message, directed to the tailgater, on a message display that is located in the rear window of the vehicle in view of following traffic. In addition to the warning message directed to the tailgater, a distance display is located in view of the vehicle driver to indicate the distance of the tailgater. An audible alarm alerts the driver to the presence of the tailgater. Additionally, a wireless remote control device allows the driver to manually select and display one of a number of pre-defined safety and courtesy messages. Multiple distance sensors provide multiple functional ranges to accommodate varying driving or traffic conditions.
