Where to Check the National Emission Standard of a Vehicle?

[DominicRose]

The location to check the national emission standard of a vehicle is: 1. Check the vehicle conformity certificate, which comes with the vehicle when it leaves the factory and clearly states the emission standard; 2. Look for the vehicle inventory list, where the emission standard can be found in the vehicle information section; 3. Examine the conformity certificate, which includes exhaust emissions and specifies the corresponding emission standard; 4. Visit the official vehicle environmental protection website, find the public query platform at the bottom of the homepage, enter the vehicle's VIN code and the last 6 digits of the engine number to check; 5. Inspect the vehicle's environmental protection label, which has a clear mark on the back indicating the vehicle's emission standard, located on the front windshield.
