What is the light transmittance requirement for window films under the new traffic regulations?
1 Answers
Under the new traffic regulations, the visible light transmittance of window films should be greater than or equal to 70%. New traffic regulations on window films: The visible light transmittance of the windshield area in the driver's line of sight and the areas used for observing the rearview mirrors while driving should be greater than or equal to 70%. No mirror-like reflective sunshade films should be applied to any window glass. For highway buses, tourist buses, buses with standing passenger areas, school buses, and passenger vehicles with a mid-engine and a width-to-height ratio less than or equal to 0.9, the visible light transmittance of all window glass should be greater than or equal to 50%, and no opaque or mirror-like reflective colored or heat-insulating papers should be applied, except for safety signs and information symbols compliant with GB30678. Precautions for replacing window films: Never opt for cheap, low-quality products, as these substandard films offer no guarantee of quality. After prolonged exposure to sunlight, the interior of the vehicle may be filled with a pungent odor, posing significant health risks. Moreover, low-quality films fail to provide effective sun protection or UV resistance.
