The colors of the annual inspection stickers represent different years. Generally, the annual inspection stickers follow the color sequence of yellow, green, and blue. For example, if the sticker was yellow in 2020, it would be green in 2021, blue in 2022, and then back to yellow in 2023, and so on. Starting from June 2020, electronic annual inspection stickers were implemented nationwide. Vehicle owners can check, download, and use electronic inspection stickers through the "Traffic Management 12123" APP. For vehicles that have already obtained electronic inspection certificates, there is no need to apply for or affix paper stickers at the vehicle management office or traffic police station. Traffic police will verify the vehicle's inspection status through law enforcement terminals during enforcement. Non-commercial small and mini passenger vehicles with 6 seats or fewer can enjoy an exemption from physical inspection within the first 6 years, but they still need to obtain the annual inspection sticker every two years. The annual inspection sticker can be applied for through the Traffic Management 12123 APP or the vehicle management office. For new vehicles, the annual inspection sticker can be printed at the vehicle management office when registering the license plate. For private vehicles older than 6 years, the annual inspection sticker must be obtained annually after passing the inspection at the vehicle inspection center.
