The environmental protection department no longer issues the qualified vehicle environmental inspection marks, but the vehicle emission inspection still exists. The motor vehicle safety technical inspection agency will take photos of the emission inspection report and upload it to the public security traffic control department. Motor vehicles that fail to pass the regular emission inspection shall not be issued with safety technical inspection certificates.

Eligible private cars are exempt from inspection for the first six years, and they need to be tested for emissions in the seventh year, but they do not need to carry environmental protection signs. If problems such as excessive exhaust gas are found, not only will inspection marks not be issued, but rectification must also be carried out.
