For Subject 4, the small car question bank contains 1,240 questions, while the large vehicle question bank has 1,715 questions. The exam paper consists of 50 questions, primarily presented in the form of case studies, images, animations, etc., with a full score of 100 points and 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, the Subject 3 test was divided into two parts: in addition to the road test, a safety and common sense test was added, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is commonly called the Subject 4 test. Officially, there is no such term as Subject 4. If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retest on your own, and no retest fee is required. There are no scheduling restrictions, but the validity period of the driving skill test permit is three years. If the applicant fails to complete the test within the validity period, the results of the already passed subjects will be invalidated.

When I was learning to drive, I also paid attention to the question bank for Subject 4. The instructor mentioned that it usually contains over 1,000 questions, and the exact number might be updated. For example, the app now shows around 1,200 questions. Don’t be intimidated by the volume during preparation—just practice more, and you’ll get familiar with it. Those driving test apps on your phone are really helpful. Make time to do a few sets of mock questions every day. The actual test randomly selects only 50 questions, so the passing probability is quite high. I remember feeling overwhelmed at first, but once I mastered key topics like traffic signs and emergency handling, it didn’t seem so difficult. Subject 4 focuses on testing safe driving awareness, so avoid rote memorization. Understanding the reasoning behind the rules is more important—for example, why drunk driving is dangerous. Apply this knowledge flexibly. Sharing experiences with friends is also beneficial; helping each other can significantly improve preparation efficiency.

As someone who often helps others prepare for exams, I have to say the subject four question bank is indeed comprehensive, usually starting with at least 1,000 questions covering key content such as road regulations and traffic signal usage. Don't be intimidated by the volume of questions. It's recommended that candidates use driving school apps to filter out key questions during preparation, as the exam only selects a small portion. The core is to strengthen the foundation of safe driving habits. More questions are actually better, as they can comprehensively test knowledge gaps. Combining theory with practical driving practice yields better results. The question bank updates quickly, adding new regulations every year, so it's important to keep up with the latest questions. Ensuring mastery of over 70% of high-frequency questions guarantees passing on the first try. Reviewing accident case analyses helps deepen memory. This subject is mandatory as it directly relates to future driving safety.

The question bank for Subject 4 is quite extensive, I recall it contains over 1,000 questions. It is well-designed to comprehensively cover all aspects of driving safety knowledge, requiring candidates to practice until they are thoroughly familiar. The exam randomly selects questions, emphasizing the cultivation of correct decision-making awareness. Daily practice can solidify the foundation of traffic rules. Don't just focus on the numbers; take time to understand the intent behind each question.
