• and
• a display part for displaying the travel lanes identified by the identifying part in the display boxes, wherein
• when a travel lane that is not displayed is present adjacent to a travel lane to be displayed in a display box at an end of the plurality of display boxes, the identifying part determines that the display box at the end is a display prohibited box that does not display a travel lane,

A non-transitory recordable storage medium storing a display program that displays travel lanes of a vehicle in a predetermined number of display boxes, the display program causing a computer to function as:

• an identifying part for identifying travel lanes that can be displayed in the display boxes, and identifying travel lanes such that a recommended lane is displayed in one of the display boxes and a maximum number of recommended travel lanes each are displayed in a different one of the display boxes, the recommended lane being a travel lane recommended for the vehicle to travel, and the recommended travel lanes being travel lanes whose traveling directions coincide with a traveling direction of the recommended lane;
• and
• a display part for displaying the travel lanes identified by the identifying part in the display boxes,
• wherein the identifying part identifies travel lanes that can be displayed in the display boxes, while relatively shifting in turn a plurality of travel lanes and the display boxes from a travel lane at one end of a plurality of travel lanes, the plurality of travel lanes being on a traveling direction side of the vehicle and being adjacent to each other.
