Extended relevant information is as follows: Driver's license examination: Subject 4 is part of the motor vehicle driver's license examination. After the implementation of the "Order No. 139 of the Ministry of Public Security of the People's Republic of China", Subject 3 examination was divided into two parts. In addition to the road test, a safety and civilization knowledge test was added, commonly known as "Subject 4", which assesses "driving ethics".
