Abstract
A warning device that is highly effective in encouraging a driver to stop visually distracted driving. The warning device includes a visually-distracted-driving determination unit and a warning unit. The visually-distracted driving determination unit determines that a driver is visually distracted if the direction in which the driver is looking is greater than or equal to a predetermined angle with respect to the front of the driver. The warning unit issues a visual warning at a position visible to the driver when the visually-distracted-driving determination unit determines that the driver is visually distracted. The warning unit is arranged on a virtual boundary line forming the predetermined angle with the front of the driver on the right and/or left side thereof.
