How Many Chances Are There for a Makeup Exam for Subject 1?

The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulates that on the day of the Subject 1 makeup exam, candidates can take the test twice. If the first attempt is unsuccessful, a second free makeup exam is allowed. If the second attempt also fails, the Subject 1 exam is terminated, and the candidate can only reschedule the exam after ten days. Subject 1, also known as the theoretical exam or driver theory test, is part of the motor vehicle driving license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is conducted on a computer with a time limit of 45 minutes. To pass the Subject 1 driving license exam, a score of 90 is required. The exam consists of 100 questions, divided into single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1 exam 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 exam precautions: Candidates should pay attention to their attire during the exam; no slippers are allowed, and electronic devices and bags are prohibited in the exam 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 exam room. Upon entering, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first time, there is a makeup exam on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. Failure to sign will render the exam invalid. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject exam allows one retake if the initial attempt fails. If you do not take the retake or fail the retake, the exam is terminated, and the applicant must reschedule. For Subject 2 and Subject 3, there are only five exam attempts. Subject 2 and Subject 3 exams can be rescheduled after ten days. If the Subject 3 safe and civilized driving knowledge exam is failed, the passed road driving skills exam results 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 exam; Subject 2 refers to the field driving skills exam; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge exam. The safe and civilized driving knowledge exam 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.
