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 Two and Subject Three tests within the validity period. If the tests are not completed within the validity period, the passing scores of the already completed subjects will be invalidated. Subject One, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license examination. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The test format is computer-based, with a time limit of 45 minutes. Subject One consists of 100 single-choice and true/false questions, each worth one point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the session. Subject One test content: Driver's license and motor vehicle management regulations; road traffic conditions and regulations; 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 freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One test precautions: During the test, students should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Inside the examination room, the identity verification station will assign a seat. After finding your seat, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, there is a retake opportunity on the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it. Failure to sign will render the result invalid. There is no limit to the number of times you can schedule the Subject One test. Each subject test allows one retake if you fail. If you do not take the retake or fail the retake, the test session ends, and the applicant must reschedule. For Subject Two and Subject Three, there are only five test attempts. Subject Two and Subject Three tests can be scheduled ten days after the previous attempt. If you fail the Subject Three safe and civilized driving knowledge test, the passing score for the road driving skills test remains valid. There are three subjects in the driver's license test: Subject One, Subject Two, and Subject Three. Subject One refers to the road traffic safety laws, regulations, and related knowledge test; Subject Two refers to the field driving skills test; Subject Three is divided into two parts: road driving skills and safe and civilized driving knowledge tests. The safe and civilized driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, the official term (as per the Ministry of Public Security Order No. 123) does not include the term "Subject Four."
