[JasperMarie]

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," Subject 4 consists of a total of 50 questions, each worth 2 points, making a total of 100 points. Questions 1-10 are true/false questions; questions 11-40 are single-choice questions; and questions 41-50 are multiple-choice questions. The exam includes question types such as image analysis, animation cases, and text descriptions. The scope of Subject 4 questions covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; knowledge of accident rescue and handling of common hazardous chemicals; comprehensive judgment of illegal behaviors and case analysis; knowledge of avoiding danger in emergencies; safe driving knowledge; and knowledge of driving ethics and civilized driving. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," there is no limit to the number of attempts for Subject 1 and Subject 4. If the first attempt on the day is unsuccessful, a make-up exam can be taken on-site. If the make-up exam is also unsuccessful, a new appointment is required, and no additional fees are charged for the make-up exam. However, it is important to note that the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within the validity period, the results of any previously passed subjects will be voided. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the safety and civilization knowledge test, commonly referred to as "Subject 4." Subject 4 is the colloquial term for the safety and civilization driving knowledge test under Subject 3 and is not a separate subject. Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. In official terms, there is no Subject 4. The safety and civilization driving knowledge test is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes. If 12 points (6 questions) are lost during the exam, the session will be terminated. Number of Questions: Depending on the type of driver's license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank in proportion. For small vehicle licenses, questions are selected from a pool of 800, while for large vehicle licenses, questions are selected from a pool of 1,023. Each question is worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also includes animation questions, image questions, scenario identification questions, and text description questions. Make-up Exam Notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the make-up exam, and there is no limit to the number of attempts. If unsuccessful, the exam can be retaken indefinitely, and no additional fees are required for the make-up exam. There are a total of 3 subjects in the driver's license test: Subject 1, Subject 2, and Subject 3. Subject 3 is divided into two parts. Subject 1 refers to the examination of road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilization driving knowledge test.
