Abstract: The present invention provides a side mirror system to offer drivers an unfettered view of their surroundings when blind side backing and parking. The M.R. Mirror Master comprises a shatterproof plastic or metal casing and is mounted to the driver and passenger side panel of the truck by means of two, heavy duty horizontal support arms positioned at the top and bottom of the mirror. The upper mirror is approximately twice as tall as the lower adjacent mirror. Perpendicularly attached to and running horizontally from the center to the base of the mirror casing is a third fully adjustable hinged mirror. This mirror is designed to provide a clear view around the truck's trailer when engaged in blind side parking.
