Are the 500 Selected Questions for Subject 4 a Must for the Exam?

[Lance]

Subject 4's selected 500 questions are not necessarily guaranteed to appear in the exam, but the probability is relatively high. Each exam randomly selects questions from the question bank, which contains 1,240 questions for small vehicles and 1,715 questions for large vehicles. The exam consists of 50 questions, primarily presented in the form of case studies, images, animations, etc. The total score is 100, with a passing score of 90. 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 an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is colloquially called Subject 4. Officially, however, there is no such term as Subject 4. Failing Subject 4 does not require retaking previously passed subjects (Subject 1, Subject 2, or Subject 3). Candidates can schedule a retake on their own, and no additional fees are required for the retake. There are no restrictions on the number of retakes, but the driving skill test permit is valid for three years. If the applicant fails to complete all exams within this period, the results of any passed subjects will become invalid.
