Can privacy glass film be applied to the front windshield of a car?

Automotive front windshields can be fitted with one-way film, but the visible light transmittance must be ≥70%. According to the "Technical Requirements for Safe Operation of Motor Vehicles": 1. Article 11.5.7 stipulates that the visible light transmittance of the driver's viewing area on the front windshield and the areas used for observing external rearview mirrors during driving must be ≥70%. All window glass shall not be affixed with mirror-reflective sunshade films. 2. For highway buses, tourist coaches, buses with standing passenger areas, school buses, and passenger vehicles with mid-mounted engines and a width-to-height ratio ≤0.9, the visible light transmittance of all window glass must be ≥50%. Except for safety signs and information symbols compliant with GB30678 regulations for buses, no opaque or mirror-reflective colored paper or thermal insulation paper shall be applied.
