Highway transportation, also known as automobile transportation, is a modern mode of transportation. It can not only directly undertake the transportation of transnational goods, but also be an important means for stations, ports and airports to collect and distribute import and export goods. Highway transportation is flexible, fast and convenient, which is conducive to the realization of "door-to-door" transportation. Highway transportation plays an important role in the foreign trade between China and neighboring countries. In addition, the import and export of some goods from the mainland to Hong Kong and Macao are also completed by road transportation.
