A driving assistance apparatus measures a position and a movement direction of a target object present in the periphery of an own vehicle. The driving assistance apparatus performs a driving assistance process of the own vehicle when the measured position of the target object is within a determination area provided in the periphery of the own vehicle. The driving assistance apparatus corrects the determination area in a direction at which the target object is measured, when the target object is determined to be moving towards the determination area based on the measured movement direction of the target object.
