A Japanese statutory car sticker that indicates an elderly driver. Its official name is 高齢運転者標識.
Japanese law decrees that persons aged 70 and over should endeavor to display this mark if their age could affect their driving. Drivers aged 75 and over are required to display the mark.
Its old design was an orange and yellow teardrop-shaped, so-called "Autumn Leaf mark". In 2011 it was changed to a green and yellow, four-leafed form.
