National V standard refers to the fifth stage national motor vehicle pollutant emission standard, with an emission limit of 0.0045 grams per kilometer. Pollutant emission standards regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. Methods to check a vehicle's emission standard include: 1. Review the motor vehicle conformity certificate; 2. Check the accompanying vehicle list; 3. Log in to the motor vehicle exhaust pollution supervision and management website; 4. Inspect the back of the environmental protection label on the vehicle's front windshield; 5. Bring the vehicle registration form to the vehicle management office for inquiry.
