What are the regulations for private car body stickers?

Internship sign: Internship drivers must use internship signs as required by regulations. The first 12 months after a motor vehicle driver initially obtains a motor vehicle driver's license is the internship period. When driving a motor vehicle during the internship period, a uniform-style internship sign must be affixed or hung at the rear of the vehicle. Failure to affix or hang the internship sign as required will result in a fine. Color: The owner of the motor vehicle can modify the body color, but special vehicle colors such as fire-fighting red, engineering rescue yellow, and the national administrative law enforcement color of white upper and blue lower are exclusive to special vehicles and cannot be used by ordinary vehicles. Car sticker area: The area of car stickers must not exceed 30% of the body area, and exceeding this requires approval. If the car sticker area exceeds 30% without approval from the public security traffic management department, it will be fined as illegal modification.
