[VonBeau]

Subject 4 is part of the Subject 3 Safety and Civilization Knowledge Test. After passing the road test, there will be a theoretical test, which is commonly referred to as Subject 4. Below are the relevant details: Subject 4: This is the safety and civilization test of Subject 3. The term 'Subject 4' is just a colloquial name; officially, there is no such designation as Subject 4. Subject 3 consists of two parts: the road test and the safety and civilization test. Subject 4, also known as the Subject 4 theoretical test or driver theory test, is part of the motor vehicle driver's license assessment. Scheduling a retake: 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. Currently, there are no scheduling restrictions for the safety and civilization driving theory test. However, the validity period of the driving skill test permit is three years. If the applicant does not complete the test within the validity period, the results of the already passed subjects will become invalid.
