A drive support apparatus includes: a reliability determiner determining a reliability of a map matching, an area definer defining a determination area to include a cross point between a self-vehicle predicted path and a nearby vehicle predicted path, an intersection node finder determining an intersection node in a travel direction of the self-vehicle based on a high map matching reliability, and a node determiner determining whether the intersection node is found in the determination area. When no intersection node is found in the determination area, a drive support level is suppressed, and when the reliability is low, drive support is provided depending on whether the cross point between the self-vehicle predicted path and the other vehicle predicted path is found. Thus, lack of the drive support in a support-required situation is prevented, while preventing a provision of an unnecessary drive support.
