Subject 4 consists of 30 multiple-choice questions, including 20 single-choice questions and 10 multiple-choice questions, with the remaining 10 being true/false questions. The total is 50 questions, primarily presented in the form of case studies, images, and animations. The full score is 100, and a passing score is 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 civilization knowledge test was added, commonly referred to as "Subject 4," which assesses "driving ethics." Because this test is conducted after Subject 3, it is commonly called the Subject 4 test. Officially, however, there is no 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 retake on your own, and no retake fee is required. There are no scheduling restrictions, but the validity period of the driving skill permit is three years. If the applicant fails to complete the test within the validity period, the passed subjects' scores will be invalidated.

I just got my driver's license last year. The fourth subject test consists of 50 questions, all in multiple-choice format, including true/false and single-choice questions. The content is all about safe driving knowledge, such as yielding to pedestrians, handling emergencies, and driving techniques in bad weather. The test is computer-based, with a time limit of 45 minutes, 2 points per question, a full score of 100, and a passing score of 90. I used the 'Driving Test Treasure' app to simulate the test several times, and after familiarizing myself with the question types, I passed on my first try. I recommend that beginners practice with more question banks, understand intersection rules and nighttime precautions, and not just memorize by rote. Understanding the principles will help you apply them flexibly when driving. After the test, I felt that this knowledge was really useful, such as knowing how to respond promptly when encountering pedestrians crossing the road or driving in rainy or foggy weather, which reduces the risk of accidents. The overall difficulty is not high, and thorough preparation is key.

The subject four test consists of 50 questions, primarily multiple-choice on safe driving knowledge, which I emphasize as crucial during driving instruction. The content covers traffic signals, emergency measures, and civilized behavior. When preparing, focus on memorizing key points such as penalties for drunk driving or highway rules. The computer-based test lasts 45 minutes, with a passing score of 90—don’t take it lightly. For review, use apps to practice categorized questions and simulate real scenarios; avoid procrastinating until the last minute. Passing ensures a smooth path to obtaining your license, helping you avoid violations in actual driving—like correctly judging right-of-way at intersections or parking positions—to ensure safety for yourself and others.

The subject 4 test consists of 50 multiple-choice questions, all focusing on safe driving topics like handling pedestrian conflicts or emergency responses. When I was preparing for my driving test, I used a mobile app to practice the question bank and passed in one go. The computer-based exam lasts 45 minutes, and passing with 90 points (out of 100) isn't difficult—just be careful since each question is worth 2 points. My advice is to focus on practicing mock tests, memorizing traffic signs, and staying relaxed during preparation.
