The purpose of the present invention is to determine the permissibility of decreasing the automatic driving level of an automatic driving vehicle on the basis of a driving load, which takes into account the relation with peripheral vehicles. This automatic driving level decrease permissibility determination device 101 is provided with: a peripheral vehicle information acquisition unit 1 which acquires peripheral vehicle information, which is information relating to peripheral vehicles traveling in the periphery of the local vehicle in which an automatic driving control device 11 performs automatic driving control switching between multiple automatic driving levels; a driving load calculation unit 2 which calculates a driving load value representing the degree of the driving load of the local vehicle on the basis of the peripheral vehicle information; an automatic driving level decrease permissibility determination unit 3 which determines the permissibility of decreasing the automatic driving level of the local vehicle on the basis of the driving load value; and an output control unit 4 which outputs the permissibility determination result of the automatic driving level decrease permissibility determination unit to the automatic driving control device 11.
