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. There are age restrictions for obtaining a driver's license, and the age requirements vary for different types of licenses. Article 11 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" states that applicants for a motor vehicle driving license must meet the following requirements: For small cars, small automatic transmission cars, small automatic transmission passenger cars for the disabled, or light motorcycles, the applicant must be between 18 and 70 years old. For low-speed trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or wheeled self-propelled machinery, the applicant must be between 18 and 60 years old. For city buses, large trucks, trolleybuses, or trams, the applicant must be between 20 and 50 years old. For medium-sized passenger vehicles, the applicant must be between 21 and 50 years old. For tractor-trailers, the applicant must be between 24 and 50 years old. For large passenger vehicles, the applicant must be between 26 and 50 years old. Applicants must complete Subject 2 and Subject 3 tests within the validity period. If the tests are not completed within the validity period, the passing scores of the already completed subjects will expire. Subject 1, also known as the theoretical driving test or driver theory test, is part of the motor vehicle driving license examination. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The test is computer-based and has 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 includes: 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 test, candidates should dress appropriately—no slippers are allowed. 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 displayed on the screen, and store personal belongings in lockers before entering the examination room. Upon entering the examination room, check your assigned seat at the identity verification counter. Once seated, begin the test. Ensure the camera is aligned with you and follow exam 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 report and sign it. Unsigned reports are 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 exam session ends, and the applicant must reschedule. Subject 2 and Subject 3, however, allow only five attempts. Subject 2 and Subject 3 tests must be scheduled at least ten days apart. If the Subject 3 safe driving knowledge test is failed, the previously passed road driving skills test scores remain valid. There are three subjects in the driving test: 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. 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."
