Is it illegal to put advertisements on the car body?

[VivienneLee]

Putting advertisements on the car body is not illegal as long as it does not exceed 30% of the car body and does not affect safe driving: 1. Unapproved and unregistered car body advertisements are illegal. They become legal only after registration and approval. However, no advertisements are allowed on the front, sides, or rear windshield of the car, as they can easily obstruct the driver's view and affect safe driving; 2. During vehicle inspections, any advertisements on the windshield will be required to be removed; otherwise, the vehicle inspection will not pass. Additionally, spraying or pasting advertisements on the car body must comply with regulations and require approval from the vehicle management department for exterior modifications; 3. Advertisements on the car body are only allowed on the sides of the car, excluding the windows. Advertisements are not permitted on the front and rear windshields, the front hood, or the trunk lid. The advertisement area must not exceed 30% of the car body to be legal.

Oh, as a friend who often modifies cars, I have to say that putting advertisements on the car body isn't necessarily illegal, but it depends on how it's done. According to our country's traffic regulations, if the ads are too extensive and block the windows, rearview mirrors, or turn signals, it's definitely a violation—my neighbor once covered his entire car with ads and ended up getting points deducted and fined 200 yuan. The content of the ads must also be legal, with no false advertising or obscene material, otherwise it violates advertising laws. For commercial ads, it's best to apply for approval from the traffic management department, especially in big cities like Beijing where enforcement is stricter. Personal stickers or small souvenirs are generally fine. The key is to consider safety—don't use highly reflective materials at night that could affect other drivers' visibility. After applying the ads, check from inside the car to ensure you can still see the road clearly. In short, legally placing ads can save money on advertising, but you can't afford to be careless.

When I first bought my car, I was so excited that I wanted to promote my small shop, so I pasted a few ads on the car doors. Nothing happened in the first few days, and I thought it was quite free; but during rush hour at an intersection while waiting for the traffic light, the reflection from the ads was too strong, and I was stopped by a traffic officer. They reminded me that it could cause distracted driving and affect safety, requiring me to remove them immediately—fortunately, I wasn’t fined. Later, I learned my lesson and only placed small ads in areas that don’t obstruct the view, like the rear bumper or the corner of the hood. According to experienced drivers, ads must not exceed 30% of the total body area, otherwise, it’s considered a visual obstruction violation; commercial use also requires registration to avoid trouble. While car ads can indeed attract attention and help promote business, they must follow the rules.

As a father, my top priority is the safety of my family during trips. While car decal advertisements aren't completely banned by law, placing them on the windshield or side windows can obstruct vision and lead to accidents—like not seeing pedestrians while reversing. Traffic police specifically target flashing or large-area ads during inspections, and fines with penalty points are inevitable. I recommend choosing stable positions like the roof or lower body for ads, ensuring they're clean and non-reflective. Use eco-friendly materials to prevent color fading and stains on the car body. Safety is no small matter—always test the effect before applying.
