What are the regulations for window tinting under the 2021 new traffic rules?

2021 new traffic regulations for window tinting stipulate that the visible light transmittance of the front windshield area in the driver's line of sight and the areas used for observing exterior rearview mirrors while driving must be greater than or equal to 70%. Window glass visible light transmittance exceeding 50%: For highway buses, tourist buses, buses with passenger standing 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%. No reflective materials allowed: Except for safety signs and information symbols on buses that comply with GB30678 standards, no opaque or mirror-reflective materials (including colored or heat-resistant films) should be applied.
When I first bought my car last year, I was particularly concerned about window tinting. The new regulations require that the light transmittance of the front windshield must not be less than 70%, otherwise, if caught by traffic police, you could be fined 200 RMB and possibly receive penalty points. Although the side windows can be slightly darker, they must still allow the outside to see the general outline inside, as poor light transmittance can impair visibility at night and increase the risk of hitting obstacles. I installed a sun protection film, specifically choosing one with a labeled light transmittance of 75%, and the 4S store tested it for free to ensure it met the standard. The regulation is quite considerate, balancing skin protection from the sun with safe driving. It's best for new car owners to check the regulations before tinting, not just focusing on the cool color, to avoid the expense of replacing the film later.
