Different types of driver's licenses require varying study hours for Subject Four. For C1, C2, and C5 licenses, the study time is 10 hours; for A1, A2, and B1 licenses, it is 16 hours; and for A3 and B2 licenses, it is 20 hours. Below are the details of the Subject Four exam: 1. Depending on the type of license, 50 questions are randomly selected from the corresponding Subject Four question bank. For small vehicle licenses, questions are drawn from a pool of 1235, while large vehicle licenses also draw from 1235 questions. Each question is worth 2 points. 2. The exam duration is 45 minutes. If you lose 12 points (6 questions) during the test, the exam will be terminated. 3. The question types include true/false (questions 1-22), single-choice (questions 23-45), and multiple-choice (questions 46-50). 4. The exam questions cover image-based questions, scenario recognition questions, and text-based questions.

I just passed the Subject 4 test last month. The instructor said it requires 10 credit hours, but the actual schedule is quite flexible. Our driving school divides the hours into two parts: theory classes and mock exams. The 6-hour theory part mainly involves watching traffic regulation animations and case studies of accidents, while the remaining 4 hours are spent practicing questions on an app. You don’t have to complete it all at once—I finished it over three days by squeezing in time here and there. The key is to repeatedly review the wrong-answer sets. A reminder to everyone: don’t just aim for the minimum hours to pass the test. The first-aid knowledge and bad-weather driving techniques in Subject 4 are actually useful on the road! Driving schools vary in management—some require clock-in hours, while others only assess mock exam scores. It depends on the requirements of the school you enroll in.

Can I take the driving test directly through self-study?

Yes. The following is relevant information about the driver's license: 1. Introduction: The full name of the driver's license is the motor vehicle driver's license, which is a certificate required by law for motor vehicle drivers. Driving a motor vehicle requires certain driving skills. People lacking such skills may cause traffic accidents if they drive recklessly. Generally, individuals cannot drive on the road without a license. However, for those who have mastered safe driving techniques, the document that permits them to drive on the road is the 'driver's license.' This indicates that a driver's license is a 'certificate of permission.' 2. Examination Content: The test subjects include three items: traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving). Before each subject test, an appointment must be made (special circumstances can be scheduled through the driving test green channel), and the test is taken after the appointment.
