Abstract
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.
