Does having stickers on all four doors exceed 30 percent?
2 Answers
Having stickers on all four doors already exceeds the 30% modification area threshold. Driving without prior approval may result in fines. Laws and regulations impose the following restrictions on vehicle modifications: 1. Prohibited modifications: The vehicle model, engine model, and chassis number cannot be altered, and the vehicle structure must not be compromised. 2. Modifications requiring approval: Changes to the vehicle's color, or replacement of the engine, body, or chassis require vehicle inspection. Additionally, replacement of the engine, body, or chassis must be accompanied by a valid motor vehicle safety technical inspection certificate. The vehicle's appearance must not undergo significant alterations and should remain largely consistent with the photo on the vehicle registration certificate. For instance, the area covered by stickers must not exceed 30% of the total vehicle surface area. Exceeding this limit requires approval from relevant authorities.
I used to put stickers on my car too, covering all four doors. At first, I didn't think it was a problem, but later I checked the regulations and found out that the exterior coverage area cannot exceed 30% of the total body area. The door area isn't very large, with each door accounting for about 3% to 5% of the body, so all four doors combined might only be 12% to 20%, usually below 30%. However, if your car is a large SUV or pickup truck, the doors are bigger, and if the sticker coverage is extensive, it might approach the limit. I recommend using a tape measure to check the length and width and calculate the ratio to avoid issues. The police are strict about inspections and can issue fines—I've seen a neighbor get penalized for exceeding the limit and having to redo the stickers, wasting money. Stickers look cool, but don't compromise the car's original safety design or cover reflective strips, as this can cause problems during inspections.
