A driving assistance apparatus includes a proximity detection section that detects an obstacle within a set distance, a behavior regulation section that performs a forced braking of a vehicle when the obstacle is detected by the proximity detection section, an arrangement memory that stores a past captured image around a target parking region, a captured image acquisition section that acquires a present captured image around the target parking region at parking or departing with respect to the target parking region, and an obstacle specification section that specifies a non-stationary obstacle around the target parking region, based on a difference between the past captured image stored in the arrangement memory and the present captured image acquired by the arrangement acquisition section. The proximity detection section assigns a stationary object with the set distance that is smaller than the set distance assigned to a non-stationary object.
