[VanessaRose]

Methods to check the vehicle's emission standard level: 1. Look at the vehicle's environmental protection label, which usually has a clear marking on the back; 2. You can visit professional query websites for verification; 3. You can refer to the vehicle's factory certificate of compliance, but generally, this document is kept at the vehicle management office, so it's advisable to make a copy for personal use; 4. Alternatively, you can personally take the vehicle's registration certificate to the environmental protection window at the vehicle management office for inquiry. Vehicle emission standards refer to the national regulations established to limit the emission of harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) from vehicle exhaust.
