The adaptive driving beam (ADB) headlamp for a vehicle includes first lamp and second lamps having a plurality of light sources. The plurality of partial patterns irradiated from adjacent light sources included in the first and second lamps respectively, partially overlap other to form a first and a second light distribution patterns. The first and second light distribution patterns formed by the first and second lamps partially overlap each other to form a light distribution pattern. The light distribution pattern is divided into a plurality of partial pattern segments that correspond to the location of a sensed vehicle ahead selected from the partial pattern segments. A dark zone is formed by the partial pattern segments by reducing a light source.
