A driving assistance device comprises an information acquisition unit that acquires movement information including a vehicle category indicating that the other vehicle is of four- or two-wheeled type, and information relating to a position and a speed of the other vehicle. The information acquisition unit determines whether the other vehicle traveling behind the vehicle is of the four- or two-wheeled type on the basis of the vehicle category. If the other vehicle is a four-wheeled vehicle, the information acquisition unit acquires speed information of the four-wheeled vehicle from four-wheeled vehicles located within a first width range in a vehicle width direction of the vehicle. If the other vehicle is a two-wheeled vehicle, the information acquisition unit acquires speed information of the two-wheeled vehicle from two-wheeled vehicles located within a second width range narrower than the first width range in the vehicle width direction of the vehicle.
