A drive planning device has a processor configured to assess whether or not there is a problem with the driver and to assess whether or not a predetermined condition has been met based on information for the surrounding environment of a vehicle, and to create a first driving plan in which the vehicle is moved to the shoulder and stopped when it has been assessed that there is a problem with the driver and the predetermined condition has been met, or to create a second driving plan in which the vehicle is stopped in the traffic lane in which the vehicle is traveling when it has been assessed that there is a problem with the driver and the condition assessment unit has assessed that the predetermined condition has not been met.
