According to relevant regulations, car body decals must not exceed 30% of the vehicle's surface area. The stickers must not affect safe driving, and their content should be healthy and positive. Additionally, decals cannot use colors reserved for special vehicles (e.g., police, ambulance). If the decals exceed the permitted area or compromise driving safety, traffic police will enforce penalties. Below are detailed guidelines on car decals: 1. Regulations stipulate that vehicle identification marks or advertisements must not impair safe driving. Decals should comply with legal standards—excessive size may obstruct visibility, and overly bright colors may distract other drivers, increasing accident risks. 2. Decals cannot be applied arbitrarily. Placing them on windows (blocking visibility) or covering license plates will result in fines. Vulgar, provocative, violent, or socially inappropriate designs should be avoided. 3. If decals cover over 30% of the body, it may be treated as unauthorized vehicle modification. Prohibited designs include emblems resembling police, firefighting, medical services, or other official insignias.

As a veteran driver with twenty years of experience, I believe that car body decals should be approached with caution. Traffic regulations stipulate that the appearance of a vehicle cannot be arbitrarily altered in a way that affects safety or recognition. Small stickers, such as cartoon patterns or small logos, are generally not checked and usually not a problem. However, if decals cover more than 30% of the car body, or if the color change is too conspicuous, it is mandatory to register the modification with the vehicle management office; otherwise, the car will fail the annual inspection, and if spotted by traffic police on the road, you may receive a ticket and penalty points. Improper decals can also pose accident risks—for example, reflective film on the windshield can blur vision and disturb driving at night. I once saw a friend get pulled over and warned for this very reason. Safety comes first, so before applying decals, it's best to check local regulations or consult a professional auto shop to avoid compromising road safety over minor aesthetics.

As a car enthusiast who often modifies cars, decals are quite common and usually not checked. I've put small stickers on my car's rear to express my personality and have never been stopped by traffic police. However, choosing the wrong location can be troublesome. For example, decals near the license plate or on the windshield can easily obstruct visibility and affect safety, which may be treated as a violation. Some places have stricter regulations, and large-area decals or overly reflective ones might result in a ticket from the police. Once, I put a large pattern on the roof and got a verbal warning due to its size. My advice is to keep decorations moderate, choose ordinary materials, and avoid anything that glows at night and disturbs others. Overall, small decals are fine, but personal expression should stay within the rules. Check online for others' experiences to avoid pitfalls.

From a safety perspective, incorrect placement of car body decals may lead to inspection by traffic police. For example, applying decals on license plates or windows that obstruct visibility could result in fines for hindering identification. Large decals that significantly alter the vehicle's color may cause the car to fail annual inspections. Small-scale stickers generally pose lower risks. Practical advice: avoid sensitive areas and refrain from placing decals around lights; opt for subtle designs to minimize issues. If stopped by traffic police, remain cooperative and provide clear explanations to reduce misunderstandings. While decals enhance aesthetics, prioritize road safety to ensure worry-free driving.

As a car enthusiast, I've noticed that car decals are a popular form of expression in Chinese culture, but regulations must be considered. Young people enjoy applying artistic patterns or slogans to convey emotions, and traffic police generally don't pay attention to minor decorations. However, if the decal area is too large or changes the vehicle's color significantly, it may be considered a vehicle modification requiring registration. Reflective stickers or commercial decals face stricter regulations and require approval. My friend applied racing-style decals without being checked, but he chose the placement wisely. From an aesthetic perspective, decals can enhance a car's appeal, but practicality and rules must be balanced to avoid inappropriate patterns causing trouble. It's advisable to measure the dimensions before applying decals to ensure they don't compromise overall visual safety.
