• wherein the automatic stop controller is configured to interrupt the automatic stop control in a case where the acceleration operation is detected by the acceleration operation detector during execution of the automatic stop control,
• wherein the automatic stop controller is configured to
• terminate the automatic stop control in a case where the acceleration operation is continuously detected by the acceleration operation detector for a predetermined fourth period or longer after interruption of the automatic stop control, and
• resume the automatic stop control in a case where a duration over which the acceleration operation is detected by the acceleration operation detector after interruption of the automatic stop control is less than the fourth period, and
• wherein the hazard light controller is configured to turn off the hazard lights in response to interruption of the automatic stop control, and to cause the hazard lights to flash in response to resumption of the automatic stop control.
