How long after passing Subject 1 will Subject 2 become invalid?

[McColton]

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 2 and Subject 3 tests within the validity period. If the tests are not completed within the validity period, the passing scores of already completed subjects will become invalid. Subject 1, also known as the theoretical driving test or driver 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 format is computer-based, with a time limit of 45 minutes. Subject 1 consists of 100 single-choice and true/false questions, each worth 1 point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the session. Subject 1 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 1 test precautions: During the Subject 1 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. Upon entering, verify your identity at the assigned seat and begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After completion, queue to collect your score sheet and sign it—failure to sign will render the result invalid. There is no limit to the number of times Subject 1 can be scheduled. Each subject can be taken once, with one retake allowed if failed. If the retake is not attended or is failed, the test session ends, 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 safe driving knowledge test is failed, the passing score for the road driving skills test remains valid. The driving 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 safe driving knowledge test. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."
