An object of the present invention is to provide a drive assisting apparatus capable of displaying a high-precision predicted locus in a camera picture in a superimposing manner while suppressing an increase of cost in a minimum value, and further, capable of displaying loci on a screen up to edges of the screen with respect to all of locus data irrespective of adjusting amounts of display positions.Display data is formed which is used to display a travel prediction locus of a vehicle corresponding to a steering angle of a steering wheel on a screen of an on-vehicle monitor (5) in a superimposing manner; adjusting data used to adjust a display position of the travel prediction locus is set; and the display position of the travel prediction locus formed based upon the display data corresponding to the steering angle of the steering wheel in connection to steering operation of the steering wheel is adjusted based upon the adjusting data, and the position-adjusted travel prediction locus is displayed on the screen of the on-vehicle monitor (5) in the superimposing manner.
