Abstract: A driving assistance apparatus includes an on-vehicle sensor and a driving assistance ECU. The ECU detects presence of a preceding vehicle traveling immediately forward of an own vehicle, on the basis of pieces of information from the sensor, chooses the preceding vehicle as a vehicle to follow, and controls a drive apparatus, a braking apparatus, and a steering apparatus such that the own vehicle follows the vehicle to follow. When the own vehicle follows a first vehicle chosen as the vehicle to follow and the speed of the own vehicle or the first vehicle is a predetermined threshold speed or lower, upon determination that the own vehicle can follow a second vehicle traveling faster than the own vehicle in a second lane located adjacent to a first lane in which the own vehicle is traveling, the ECU changes the vehicle to follow from the first vehicle to the second vehicle.
