There are three scenarios for the timing of the Subject 4 exam after passing Subject 3: taking it directly on the same afternoon; no appointment required within 9 days—you can take the Subject 4 exam at the test center within 9 days after passing Subject 3 by presenting your ID; or scheduling an appointment after 10 days, with success depending on the current number of examinees, student priority, and temporary arrangements at the test center. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license . It includes requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes. Making mistakes totaling 12 points (6 questions) will terminate the exam. Number of Questions: Depending on the type of license, 50 questions are randomly selected from the corresponding Subject 4 question bank. For car licenses, questions are drawn from a pool of 800, while for large vehicle licenses, they are drawn from 1,023. Each question is worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also includes animation-based questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: If you fail Subject 4, you only need to retake Subject 4. The driving school will schedule the retake, with no limit on the number of retakes. You can retake until you pass, and no retake fee is required. Subject 4 Exam Tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, don’t just memorize the correct answer. Refer to regulations, textbooks, or reference materials to understand the reasoning behind the mistakes. Categorize and summarize questions. Use the question bank analysis to group similar questions: many questions in the bank are similar and easily confused, so they should be analyzed together. For example, traffic signs for walking, hiking, pedestrian crossing, and pedestrian zone warnings are very similar and easily mixed up. Grouping them during study helps avoid errors. Use memorization techniques: Many questions in the bank involve numbers. Summarizing these numbers can make them easier to remember. The driving test consists of three main subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 4 is the colloquial name for the Subject 3 Safety and Civilized Driving Knowledge Test and is not a separate subject. Subject 1 refers to the traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge test. The safety and civilized driving knowledge test is conducted after Subject 3.

I remember you can schedule the Subject 4 test right after passing Subject 3. Once the system synchronizes the results, you can book the exam. Generally, after the results are uploaded on the same day, you can see the available dates on the Traffic 12123 app the next day. However, it depends on the processing speed of the local vehicle management office—it can take as fast as 24 hours or up to 2-3 days for slower cases. After booking, the earliest possible test date might be the next day, as many places schedule test sessions weekly. I recommend starting to practice Subject 4 questions immediately after passing Subject 3. Use the driving test app to take mock exams several times daily, and once you consistently score above 90, go ahead and book the exam. This way, you can get your license the fastest.

A common practice among our driving school students is to go directly to the exam center's computer room to practice questions for Subject 4 after passing Subject 3. With good luck, they can take Subject 4 on the same afternoon. Of course, this depends on whether your results are uploaded in real-time and whether there is a combined exam in your local area. It is recommended not to leave in a hurry after passing Subject 3; instead, ask the exam center staff if you can schedule Subject 4 on the same day. If not, the data is usually synchronized to the reservation system within 3 days. Keep your phone accessible, and once you receive the SMS confirming your successful reservation, go for the exam. The question bank consists of just over 1,700 questions, and with focused practice for 3 days, most can pass.

You can take the test as soon as the next day! After passing Subject 3, the system will automatically unlock the booking permission for Subject 4. Last time, I finished Subject 3 on Thursday morning, and by Friday morning, the traffic app showed it was available for booking, so I directly scheduled a session for Saturday. Note that you need to complete 10 credit hours before you can book the test, but most people finish them before Subject 3. Bring your ID card and a document folder for the exam, and some test centers also require your Subject 3 score report. The questions are actually simpler than Subject 1, mainly focusing on safe driving knowledge. Before the test, focus on memorizing traffic police hand signals and accident handling procedures.

It depends on regional efficiency. In big cities like Shenzhen and Guangzhou, you might get a spot for the Subject 4 exam in the afternoon of the same day, while in smaller cities, waiting two or three days is normal. The key point is that your Subject 3 results need to be archived in the system. If the driving school helps submit the materials, it will be faster. Don’t just wait for notifications; log in to 12123 daily to check the appointment status. It’s recommended to schedule the exam on a weekday, as there are more slots available and you won’t have to compete for spots. My colleague passed Subject 3 on Wednesday, booked the exam for the following Monday on Thursday via 12123, with just four days in between. Bring your documents to the DMV, take the exam, and get your license on the spot.

Strictly speaking, there is no mandatory waiting period. As long as your subject three test result shows as passed in the vehicle system, you can schedule the subject four exam the next day. However, in practice, there is a data synchronization time, which is usually completed within 24 hours. Remember that the official name of subject four is the Safe and Civilized Driving Exam, so don’t select the wrong section when scheduling. You can choose either the vehicle management office or a socialized testing site, with the latter having more available slots. You have three exam attempts, and if you fail, you must wait 10 days to retake it. Before the exam, focus on animated questions and multiple-choice questions, as these are where most points are lost. If you wear glasses for nearsightedness, note that failing the photo test will disqualify you from taking the exam.
