ABSTRACT:
A safety mirror mountable adjacent the perimeter of a vehicle is provided for affording vehicle drivers the ability to observe from the driving position an area extending outwardly from at least one location inboard of the portion of the perimeter of the vehicle visible from the location of the mirror. The mirror has a convex aspheric elliptic paraboloid image reflecting mirror surface. The curvature of said mirror surface decreases from a point of maximum curvature spaced from a point of minimum curvature at the peripheral edge of the mirror. A plurality of such safety mirrors may be used as at the front corners of a school bus to afford the driver a view of an area contiguous to the sides of the vehicle and in front of the vehicle, as well as beneath the front of the vehicle ahead of the front wheels thereof.
