The present invention teaches the use of a blind spot exposure system comprised of two consecutive reflective mirror surfaces. The first mirror surface is formed of an electrochromatic polymer while the second reflective surface is composed of conventional reflective mirror glass. The two surfaces are positioned such as the first electrochromatic reflective surface forms the reflected view in the vehicle's side mirror during the system's normal operating state. Once the system is activated electrical voltage is applied to the electrochromatic first surface rendering it transparent thereby uncovering the conventional reflective mirror surface behind it which is offset by a fixed blind spot exposure angle that may range between +4 degrees and +24 degrees. The present invention also teaches of a number of alternative embodiments including: an anti-glare automatic dimming mode based on the use of an optional external light sensor, the integration with a vehicle's turn signals or external sensors as means of activating the blind spot exposure state, the ability to produce a speed sensitive mode in which the system engages in blind spot exposure mode for a shorter period of time at higher vehicular speeds; and the use of LED indicators to provide visual notification whenever the system in a given side mirror is in an expanded blind spot exposure state.
