Why is the annual inspection sticker white?
1 Answers
The reason why the annual inspection sticker is white is to facilitate inspection. Without needing to get close, one can roughly determine whether the vehicle has undergone the annual inspection within the specified date based on the color from a distance. The background colors of the motor vehicle inspection qualification stickers are yellow, green, and blue. These three colors cycle every 3 years. The main reason is that traffic police can quickly determine whether a vehicle's annual inspection has expired based on the color during checks. The current annual inspection stickers no longer include a separate environmental protection qualification mark, as the Chinese environmental protection department has ceased issuing environmental protection qualification marks.
