In a vehicular wireless communication apparatus in a subject vehicle, a rear vehicle determination process determines whether another vehicle is a rear vehicle within a predetermined range based on a past locus of the subject vehicle determined by a subject-vehicle locus determination process, and a locus information-set of the another vehicle received by a wireless communication portion. When the another vehicle is determined to be the rear vehicle, a necessary-position determination process determines position information-items of two end points of a line segment of the past locus of the subject vehicle which intersects with a perpendicular line drawn from a present position of the another vehicle. A simple transmission process transmits a locus information-set including (i) a present position information-item of the subject vehicle and (ii) the necessary-position information-item determined in the necessary-position determination process, from the wireless communication portion.
