What decals should be affixed on car windows?

[LukasLee]

Vehicle inspection compliance decal, compulsory insurance decal, and environmental protection inspection compliance decal - these three decals were previously indispensable and had to be neatly affixed on the front windshield. However, with the introduction of new regulations, the environmental protection inspection compliance decal has been abolished, leaving only the vehicle inspection compliance decal and compulsory insurance decal to be displayed. Note: Some regions, such as Beijing, have begun pilot programs to eliminate the compulsory insurance decal and replace it with electronic policies. In other cities and regions where the electronic policy initiative has not yet been implemented, the compulsory insurance decal must still be displayed. It is worth mentioning that car owners using electronic policies are advised to affix the decal when driving to cities where the policy has not been implemented.
