To be exact, the Chinese authorities have never said anything about "heavy trucks" or even trucks in the classification of automobiles. "Truck" is a parked word, which originates from "Car" in English. In English, the word for large trucks should be "Truck" rather than "Car".
China's automobiles are divided into two categories, namely passenger cars and commercial vehicles. Commercial vehicles are also divided into passenger cars, freight cars and semi-trailer tractors.
