How to Determine the National Emission Standard?
1 Answers
Methods to check the emission standard are as follows: 1. Identify based on the environmental protection label issued during the vehicle inspection. When the vehicle passes the inspection, an environmental protection label will be issued and affixed to the upper right corner of the windshield. Pay attention to the emblem on the label—for standards before National IV, the number of stars represents the vehicle's emission standard. For example, three stars indicate National III. 2. Online inquiry: Visit the official website of the local traffic management bureau to check detailed vehicle information, including traffic violation records and emission standards. The Motor Vehicle Environmental Protection Website also allows you to check the emission standard by entering the vehicle's brand and model.
