At present, only some of the four cars in Zhanjiang are in circulation, and the rest are all five cars in Zhanjiang. According to the Opinions, all localities should not set other restrictions on vehicles that have passed the environmental protection inspection at the transfer site and meet the emission standards of motor vehicles in use at the transfer site (except vehicles in key areas for air pollution prevention and control determined by the state and vehicles that the state requires to be eliminated). The emission standards of in-use vehicles mentioned here do not refer to the emission standards required for new car sales in the transfer area, but refer to the emission standards of vehicles allowed to drive in this area. In other words, Zhanjiang currently restricts the entry of vehicles that do not meet Zhanjiang's emission standards. No matter how many cars there are in China, as long as they do not meet the emission standards, they will be restricted from entering.
