Applying decorative stickers on the exterior of the car body is allowed on highways and does not pose any issues. Only during vehicle inspections, if these decorative stickers do not exceed 30% of the car body's surface area, they do not need to be removed. If they exceed this limit, they must be removed for the inspection. Below is more information about car wraps: 1. Polluting the in-car air environment: This can harm health. Regular glass protective films undergo health and safety testing and do not emit harmful volatile substances. However, low-quality films, due to cheap materials and simple manufacturing processes, not only tend to emit volatile substances but also often contain hazardous materials like formaldehyde and benzene in their materials and adhesives. Over time, these substances decompose and volatilize, posing serious health risks to car owners. 2. Public safety concerns: This is the main reason why car wraps are restricted in foreign countries. In Europe and America, where weapons are widespread, if someone inside the car is holding a gun and shooting, it would be impossible to detect from outside, posing a serious threat to personal safety. Although China does not have such widespread weapon issues, and the risks for law enforcement are relatively lower to some extent, there are still instances of serious crimes like kidnapping and robbery involving cars. Imagine if a criminal vehicle has tinted windows, victims inside cannot call for help, and passersby outside cannot clearly witness the crime happening inside to alert the police promptly. This creates significant challenges for subsequent criminal investigations and evidence collection.
