Because Subject 4 is actually the safety and civilized driving knowledge test of Subject 3, which is why there is no Subject 4 in the 12123 app. Below are the relevant explanations: Introduction to Subject 3: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of driving license. Introduction to Subject 4: Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. The Subject 3 examination is divided into two parts: besides the road test, there is an additional safety and civilized driving knowledge test, 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. However, officially, there is no such term as Subject 4.

I remember when I was learning to drive and taking the license test, I really couldn't find the theoretical exam for Subject 4 in the Traffic Management 12123 App. After careful consideration, I realized it's mainly used for scheduling exams and checking violations, not for specific learning content. Probably during the design phase, the focus was on the app's convenience services, like easily scheduling exams for Subjects 1 to 3, but the safety and civilized driving knowledge for Subject 4 requires finding other resources, such as driving school textbooks or using learning apps like 'Driving Test Treasure.' Actually, Subject 4 is super important—it teaches you how to avoid accidents and drive courteously in real-world situations. I suggest new drivers not rely solely on the app but spend more time reading books and practicing questions. This way, you can pass the exam solidly and ensure safe and worry-free driving. I went through this myself, and with strong theoretical knowledge, I now drive with much more confidence.

Having driven for so many years, I've seen plenty of beginners ask about this. The Traffic Management 12123 App indeed doesn't include content for Subject 4, likely because it focuses on administrative functions like violation handling and information queries, while Subject 4 is purely theoretical for the driver's license test and requires systematic learning materials. I guess the authorities want to keep the App simple and uncluttered, avoiding bloat, so they outsource the knowledge content to driving schools or online platforms. Thinking back to when I took Subject 4, I just used paper books to review, and later even helped colleagues look up materials. My advice is to make more use of official question banks and mock exam software, not just rely on the App. After all, safe driving isn't something you can learn just by clicking buttons—you need to build a solid foundation.

I found that the Traffic Management 12123 App focuses on practical services, so it's normal that it doesn't include the subject 4 test. It handles transactional tasks like exam scheduling and score checking, while the content of subject 4 belongs to the educational part, which might be in a specialized learning system. I think this design avoids information confusion and helps users quickly find service entry points. I recommend using a driving test App alongside, as those have complete question banks and video explanations. Learning safe driving is crucial, and I remind everyone not to slack off—take good notes and practice more to pass the test in one go, saving time and effort.
