This mirror regulation stipulates (1) requirements for the location and operation of rearview mirrors; (2) that vehicles with GVWR of 11,340 kg or more must have outside mirrors of unit magnification with 323 cm2 or more of reflective surface with an average reflectance of 35% or more; (3) mirrors must be mounted on both sides so the driver can see the truck along the inner sides of the driver and passenger-side mirrors and has a representative view of the rearward area in the rest of the mirror; and (4) that mirrors of "unit magnification” must provide a reflected view that is equivalent to that of the actual view at the same distance. These requirements are critical to maintaining accurate speed and distance judgments of images in mirrors, helping drivers to safely operate commercial vehicles, and of which Velvac vision systems are designed to exceed.
