According to the "Regulations on the Application and Use of Motor Vehicle Driving 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 driving test or driver's theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. Subject One consists of 100 questions, including single-choice and true/false questions, with each question worth 1 point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the exam. Subject One test content: Driving 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 a locker before entering the examination room. Upon entering, 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 completion, 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 can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail the retake, the test will be terminated, and you must reschedule. However, Subject Two and Subject Three only allow five test attempts each, and retakes must be scheduled at least ten days later. 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 driving 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 consists of 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 terminology (i.e., the Ministry of Public Security's Order No. 123) does not include the term "Subject Four."
