How Long Can National IV Vehicles Be Driven?

[VonMarcus]

As long as the vehicle is in good condition, National IV vehicles can continue to be driven. The rumor that National IV vehicles cannot be driven after 2020 is false; the government is unlikely to implement such measures for now. The maximum mandatory retirement period for National IV trucks is 15 years. National IV diesel vehicles can be driven indefinitely as long as they are in good condition. The only concern is that in a few years, first-tier cities may impose restrictions on National IV vehicles. National IV refers to the level of total vehicle exhaust emissions—the higher the number, the higher the standard, and the lower the corresponding engine emissions. Vehicle emissions include pollutants such as carbon dioxide, sulfides, nitrogen oxides, chlorofluorocarbons, and non-methane hydrocarbons, which can damage the ozone layer.
