A vehicle driving assistance apparatus installed in a vehicle displays a predetermined light pattern on a road surface around an own vehicle. The vehicle driving assistance apparatus includes a coherent light source that emits a light source beam, a road surface projection optical system that scans the light source beam and emits the projection beam, a road surface presence information retention section and a control circuit. The control circuit stops the projection beam toward the position where the road surface is absent.
