The purpose of this study was to determine the degree to which motor vehicle window tint films impede a police officer's ability to see clearly into a stopped vehicle. Three hundred and twenty subjects were asked to view the contents and occupants of one of four experimental cars. One car had no aftermarket tint film and three had varying degrees of tinted windows. In general, this study found that the ability of subjects to detect occupants and objects in vehicles was substantially diminished as the level of window tinting increased. However, the detrimental effects of window tinting on viewing occupants and objects within a vehicle at night were substantially reduced when headlights and a spotlight were shone at the stopped vehicle, as would be the case in a traffic stop.
