National V vehicles can still be registered in regions or cities where the National VI standard has not been implemented. However, in some areas or cities where the National VI standard has already been implemented, National V vehicles cannot be registered. Below is relevant information about National V: 1. Meaning of National V: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, also known as the "National V Standard," has an emission control level equivalent to the European Union's currently implemented Stage 5 emission standard. The EU has been enforcing this standard since 2009, imposing stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by motor vehicles. From National I to National IV, each upgrade in standard reduces vehicle pollution by 30% to 50%. Cities like Beijing, Shanghai, Nanjing, and some cities in Guangdong have already started implementing the National V standard. 2. National V Emission Standard: This is an exhaust emission standard set by environmental protection authorities. The higher the number, the stricter the standard, meaning that the higher the number, the relatively lighter the pollution from exhaust emissions.
