DRIVING ASSISTANCE APPARATUS AND PROGRAM
A driving assistance apparatus determines whether or not a road section corresponding to a current location of an own vehicle corresponds to a no-passing zone. A leading vehicle present ahead of the own vehicle is detected. An operation state of the detected leading vehicle is recognized. A passing maneuver performed by the own vehicle to pass the detected leading vehicle is detected. A warning operation to output a warning to a driver of the own vehicle is performed, when the passing maneuver is detected under a condition that the road section corresponding to the current location is determined to correspond to the no-passing zone. The warning operation is prohibited when the recognized operation state of the leading vehicle meets a predetermined passing-allowed condition that is a condition under which passing is allowed.
