Because Subject 4 is actually the Subject 3 Safety and Civilization Knowledge Test. It is commonly referred to as Subject 4 simply because it requires a separate appointment. Additional information about Subject 4: Theoretical Test: Subject 4, also known as the Subject 4 Theoretical Test or Driver's Theoretical Test, is part of the motor vehicle driver's license examination. Test Content: After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: besides the road test, a Safety and Civilized Driving Test was added. Since this test is conducted after Subject 3, it is commonly referred to as Subject 4. Test Composition:

This is a pretty common question, and I've been through it myself. I remember when I was taking my driving test, the instructor always said that Subject 4 was the safety and civility part of Subject 3 because it essentially tests theoretical knowledge about safe driving. Initially, the driving test only had three main subjects: Subject 1 (theory), Subject 2 (field test), and Subject 3 (road driving). But later, the Ministry of Transport added safety and civility content as a separate module, which people habitually called Subject 4. However, in the official classification, this subject is integrated into Subject 3, emphasizing the mastery of civilized norms on top of practical road driving—like no drunk driving, yielding to pedestrians, etc.—to make driving habits more systematic. Many people find it odd to see the screen display "Subject 3 Safety and Civility" during the test, but that’s purely for naming consistency to facilitate exam organization and doesn’t affect the content or difficulty. My advice is to practice more questions and focus on safety points—it’ll be easy to pass. Now, every time I drive, I recall that knowledge, and it’s really practical.

As a young person who just got my driver's license, I was curious why the app showed 'Subject 3 Safety and Civility' instead of Subject 4. My driving instructor explained that this test was originally a supplementary to Subject 3's road driving, focusing on safety awareness and civilized driving, covering details like traffic rules and emergency handling. Initially, the official definition only had three subjects, but later the safety module expanded into a separate test paper, which people nicknamed Subject 4. The exam system still uses the old name to maintain standardization and avoid confusion. I was also worried about getting it wrong before the test, but the preparation points are the same: watch more videos to learn about accident cases and memorize right-of-way rules at intersections. This way of preparing not only made it easy to pass but also reduced risks in actual driving. Personally, I think this arrangement is quite reasonable.

As someone who has been through it, I only realized after the test that Subject 4 is always labeled as the Safety and Civilization Exam of Subject 3. The reason is simple: the traffic safety authorities designed this section as an additional theory component to road driving, directly linked to Subject 3 content. For example, learning how to handle emergencies and practicing courteous driving fall under the safety and civilization module, with a unified name for easier . During actual training, instructors emphasize this point, advising not to overlook safety details during review to avoid mishaps when actually driving. Just remember the core principles.

From a professional perspective, categorizing Subject 4 as the Safety & Civility Test of Subject 3 is clearly defined by traffic regulations. Authorities consider safety knowledge a natural extension of road driving skills, as the exam covers accident prevention and courteous yielding, hence the naming under Subject 3 framework. This integration enhances learning coherence and prevents trainees from separating theory and practice. In daily law enforcement, this arrangement improves driving literacy and reduces violations. I recommend focusing on sign recognition and emergency handling during exam preparation to ensure passing at first attempt.

That's an interesting question! I've researched the naming of DMV exams and found that Subject 4 is actually called Subject 3 Safety Knowledge Test. This naming stems from historical conventions: originally, the driver's license testing system was designed with simplified modules, incorporating the safety component into Subject 3. Nowadays, this doesn't affect exam preparation—the content still covers traffic rules and civilized driving. By the way, there are some fun facts hidden in the exams, like pass rate statistics or regulation updates. I'll share more details next time. The key is to practice more questions to familiarize yourself with scenarios and ensure a smooth pass.
