Abstract

Abstract Pivotable side-by-side mirror members assist the driver of a tractor-trailer or other vehicles in backing and having an unobstructed rear view. The mirror apparatus includes a transverse frame member which allows for a greater and more precise adjustment of the mirror members to each other and to the vehicle for a more complete rearward view.
