1. Reasons for Amendment

   As the Rules on Motor Vehicle and Automotive Parts Performance and Requirements were revised (Ordinance No. 797 of the Ministry of Land, Infrastructure and Transport, promulgated on December 24, 2020) to harmonize with international standards that reflect new technologies such as high-voltage electrical devices and driving batteries of two-wheeled vehicles in order to ensure the safety of electric two-wheeled vehicles, and such Rules were revised to expand the installation target of the emergency automatic braking system to passenger cars and freight/special motor vehicles with a gross vehicle weight of 3.5 tons or less and harmonize fuel systems and collision criteria for small trucks with international standards, this amendment aims to improve and supplement the shortcomings that have emerged from the operation of the current system, such as clarification of test conditions and revision of referenced provisions, in order to provide the test methods and procedures necessary for the implementation of the revised provisions and prevent confusion during the test.
