Does the black roof wrap AC pillars exceed 30%?
2 Answers
Applying a black roof wrap to AC pillars does not exceed 30%. Generally, the area of the car roof does not exceed 30% of the entire vehicle body, so only applying a roof wrap does not require filing for approval. If the roof area of your car is large and you are unsure whether it exceeds the standard, it is recommended to first call the vehicle management office for clarification before making a decision. Vehicle color change: It is worth mentioning that not all color combinations are permitted. The body color change cannot mimic the styles of police cars, taxis, fire and ambulance vehicles, or chrome-plated body wraps. Additionally, the color change should not exceed three colors. Therefore, it is best to consult the vehicle management office with a color chart before proceeding with the color change. Black roof wrap can pass annual inspection: Because applying a black roof wrap does not constitute illegal modification, and current laws and regulations do not explicitly prohibit vehicle color changes. However, when applying the wrap, it is advisable to avoid unconventional colors such as electro-optic film or chameleon colors, as they may not pass the annual inspection later and could also affect traffic safety to some extent.
As a seasoned car enthusiast who frequently dabbles in vehicle modifications, I find this issue quite common. Black roof wraps are quite trendy these days, especially for making the roof and A-pillar/C-pillar areas look cooler, but you need to pay attention to light transmittance. In China, regulations stipulate that the light transmittance of the front windshield must not be less than 70%, and the same strict standard applies to the front side windows. However, there are generally no rigid standards for the roof and rear windows, as long as they don’t compromise driving safety. If the 'over 30' you mentioned refers to a light transmittance below 30%, that’s way too dark—it could make it hard to see the road at night and might even attract the attention of traffic police. I recommend using a professional light meter to check the actual transmittance of the wrap; keeping it above 50% is safer and more worry-free. Also, choosing high-quality black wrap material can provide sun protection and even save fuel. In short, modifications should reflect personality but not take unnecessary risks—safety should always come first.
