There are at least three. Here is the relevant introduction about the stickers on the car: Stickers: When driving a motor vehicle on the road, the vehicle license plate should be hung, and the inspection qualification mark and mark should be placed, and the motor vehicle driving license should be carried with the vehicle. After annual inspection: After the annual inspection of a general family car is completed, there will be three marks. The motor vehicle inspection qualification mark is valid for one year. The car environmental protection mark is issued for the needs of energy-saving and emission-reduction inspection and regular environmental protection inspection of the car, which is divided into yellow and green marks, and annual inspection. The compulsory insurance mark, at present, there are only two marks that need to be pasted on the vehicle: the compulsory insurance and the annual inspection mark. The environmental protection mark has been canceled and merged with the annual inspection mark. Private cars with 6 seats or less, including 6 seats, are exempt from online inspection within 6 years of new cars, but the compulsory insurance needs to be provided to the traffic police department for annual review and the annual inspection mark needs to be replaced every 2 years. Starting from the 6th year, the car needs to be inspected once a year until the vehicle is 15 years old.

Having driven for decades, I believe the number of stickers on a car should focus on essential types. The sticker and annual inspection sticker are two must-haves, fixed on the windshield. In most places, you’ll also need an environmental sticker, making three basic ones. But nowadays, younger drivers love adding personal decals, like anime stickers or labels on the rear, pushing the count up to four or five. Older cars tend to keep it simpler—excluding the brand emblem, extra stickers shouldn’t obstruct visibility; safety comes first. Over time, stickers fade and need timely removal, or they’ll look unsightly and hinder driving. Looking back, three or four stickers per car seem just right—no need to imitate those covered in a dozen. The key is regular checks and updates to avoid fines for expired stickers.

I have about five or six decals on my car: one mandatory sticker and one annual inspection sticker on the front windshield, three anime-themed decals on the rear window, and a corny joke sticker on the back. It's all personal preference—my friend's car is even more extreme, covered in over a dozen decals like an art gallery. But you’ve got to choose high-quality waterproof decals, or they’ll peel and look awful after prolonged sun exposure. The two official stickers must be properly displayed to avoid police trouble. Decorative decals add personality, but don’t overdo it and block visibility—I keep mine under six. For maintenance, clean the surface before applying to prevent bubbles, and use professional adhesive remover when peeling to avoid damaging the paint. The number of decals is up to personal taste, but safety always comes first.

At least two stickers are required on the vehicle: the sticker and the annual inspection sticker, which are mandated by law and must be affixed to the designated area of the front windshield. In some cities like Beijing, an additional environmental sticker or emission label may be required, making it three. Extra stickers such as brand logos are not mandatory and do not count toward the total, but decorative stickers are optional—it's recommended to limit them to one or two to avoid issues. The number of stickers varies by location, and simplicity is best. Ensure annual updates of official stickers to avoid fines. Avoid excessive non-essential stickers that may obstruct driving. The core number of vehicle stickers should be kept to two or three.

There are a total of four or five stickers on our family car: one sticker and one annual inspection sticker on the windshield, and three cartoon characters stuck by the kids on the rear window. Too many stickers make cleaning difficult, and we often worry about adhesive residue or peeling causing accidents. It's best to educate children to stick fewer stickers, with safety as the priority. The brand logo at the rear might not count as a new sticker. Keep the total number of stickers within four, and regularly wipe them with a damp cloth to prevent aging. From maintenance experience, heating the stickers before applying helps them adhere better. The fewer stickers on the car, the less hassle—don't exceed the limit.

It is recommended to minimize the number of decals on the car, with the focus being on the mandatory and annual inspection stickers in their fixed positions. However, brand logos may not count as additional decals; decorative stickers should be limited to one or two, with a total of three to four being optimal. Excessive stickers can obstruct visibility or cause paint discoloration, especially after prolonged sun exposure. From a maintenance perspective, choose weather-resistant materials when applying stickers and use professional adhesive removers to avoid damaging the car when removing them. Experience shows that it's best not to exceed four stickers on a car for safety and peace of mind. A single custom decal can represent individuality, and fewer stickers mean less cleaning hassle.
