Lane-use signals are devices commonly mounted to the fascia or front edge of the canopy, centered over a toll lane, and used to indicate an open or closed lane operating status. One of the two types of signals most commonly installed in toll plazas use a red “X” for closed and green “↓” for open. These symbols are primarily formed from LEDs and fabricated as part of a rectangular environmental enclosure or part of a multi-line changeable message sign that is also used to display methods of payment supported by the installed lane equipment. The other commonly used signal is horizontally aligned red and green traffic signal heads.
