HB 120 -- Vision-Reducing Material on Motor Vehicles Sponsor: O'Connor Under current law, no person may operate a vehicle with vision-- reducing material applied to a windshield, sidewing, or window located to the left and right of the driver which reduces visibility from within or into the motor vehicle. Use of vision-reducing material with 35% light transmission is permitted only with a physician's prescription. This bill permits any person to use vision-reducing material with a light transmission of 35% or less, plus or minus 3%, and a luminous reflectance of 35% or more, plus or minus 3%, except on the windshield, sidewing, or window located to the left and right of the driver.Copyright (c) Missouri House of Representatives
