1. A driving assistance apparatus that assists driving of a vehicle, the driving assistance apparatus comprising:
an inter-vehicle distance detection section that detects an inter-vehicle distance between a host vehicle and a preceding vehicle;
an overlap detection section that detects an overlap between the host vehicle and the preceding vehicle; and
an alarm control section that controls an alarm outputted on a display, based on the inter-vehicle distance and a change in the overlap, wherein:
the overlap detection section detects the overlap between the host vehicle and each of a plurality of the preceding vehicles, and
in a case where the overlap between the host vehicle and a first preceding vehicle of the plurality of preceding vehicles changes in a decreasing direction, the alarm control section suppresses an output of the alarm, and in a case where the overlap between the host vehicle and a second preceding vehicle of the plurality of preceding vehicles changes in an increasing direction while the output of the alarm is suppressed, the alarm control section stops suppressing the output of the alarm, the second preceding vehicle differing from the first preceding vehicle.
