Abstract: A dual rear view mirror unit for motor vehicles is disclosed. The unit comprises a mounting frame having an upper and a lower rear view mirror thereon. Each of the mirrors is independently adjustable. The upper mirror and lower mirror are positioned so as to define a substantial gap between them. This allows the operator of the motor vehicle unobstructed lateral vision. The lower mirror is mounted on the frame so that its upper edge is beneath the lateral line of vision of the operator. Likewise the upper mirror is mounted on the frame so that its lower edge is substantially above the said lateral line of vision. With this construction the upper edge of the upper mirror protrudes substantially above the cab of the truck. The upper mirror is tilted so that its upper end inclines toward the rear of the truck. This substantially aids in the dissipation of fog and rain which may accumulate on the upper mirror's surface.

Abstract: A side mirror system is disclosed for securing to the cab door of a truck. The mirror of the system is a conventional elongated, rectangular production mirror secured to mounting brackets so that the upper edge of the mirror is beneath the direct line of sight of the driver of the truck so as to minimally obstruct his side angle vision. The mirror is preferably vertically adjustable with respect to the mounting brackets to allow the driver of the truck to adjust the mirror vertically to a position to minimally obstruct his side angle vision while allowing unobstructed rear vision through the mirror.
