According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the validity period of the study driving certificate is three years, but the expiration date must not exceed the upper age limit for application. Applicants must complete the Subject 2 and Subject 3 tests within the validity period. If the tests are not completed within the validity period, the passed subject results will be invalidated. Subject 1, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test format is computer-based, with a time limit of 45 minutes. Subject 1 test content includes: driver's license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and cargo vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 2 test content includes: For large buses, tractors, city buses, medium-sized buses, and large trucks: stake test, hill start, parallel parking, single-plank bridge, curve driving, right-angle turn, narrow gate, continuous obstacles, bumpy road, U-turn on narrow roads, and simulations for highways, continuous sharp mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling. For small cars, small automatic transmission cars, small automatic transmission cars for disabled persons, and low-speed cargo vehicles: reverse parking, hill start, parallel parking, curve driving, and right-angle turn. For three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, and light motorcycles: stake test, hill start, and single-plank bridge. For wheeled self-propelled machinery, trolleybuses, and trams, the test content is determined by the provincial traffic management department of the public security authority. For the first and second categories of vehicles listed above, the provincial traffic management department may add test content based on actual conditions. There is no limit to the number of times Subject 1 can be scheduled. Each subject can be taken once, and if failed, a retake is allowed. If the retake is not taken or is failed again, the test is terminated, and the applicant must reschedule. For Subject 2 and Subject 3, there are only five test attempts, and rescheduling must be done at least ten days later. If the Subject 3 safety and civilized driving knowledge test is failed, the passed road driving skills test results remain valid. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safety and civilized driving knowledge tests. The safety and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject 4.
