How Many Chances Are There for the Subject 4 Exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," there is no limit on the number of attempts for the Subject 4 exam. If you fail the first attempt on the same day, you can retake it immediately. If you still fail, you need to reschedule the exam, and no additional fees are required for retakes. However, it is important to note that the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within this period, the results of any previously passed subjects will be invalidated. The Subject 4 exam consists of 50 questions, presented in formats such as case studies, images, and animations. The total score is 100, with a passing score of 90. Subject 4, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and the addition of a safety and civics knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Subject 4 is the colloquial term for the safety and civics driving knowledge test under Subject 3, not a standalone subject. Since this test is conducted after Subject 3, it is commonly called Subject 4. Officially, there is no Subject 4. The safety and civics driving knowledge test is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 45 minutes. If you make 12 mistakes (6 questions) during the test, the exam will be terminated. Number of Questions: Depending on the type of license being tested, 50 questions are randomly selected from the Subject 4 question bank, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. Questions 1-10 are true/false; 11-40 are single-choice; and 41-50 are multiple-choice. The exam also includes animated questions, image-based questions, situational 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, and there is no limit on the number of retakes. You can retake the exam until you pass, and no additional fees are required for retakes. Subject 4 Exam Tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answers. Refer to regulations, textbooks, or reference materials to understand the reasons behind the mistakes and internalize them. Categorize and summarize questions. Refer to the question bank analysis for classification and identify similar questions: Many questions in the bank are similar and easily confused, so they should be analyzed and categorized. For example, traffic signs such as "pedestrian," "walking," "pedestrian crossing," and "caution pedestrian crossing" have similar patterns and can be confusing. Grouping them during study helps avoid mistakes. Find memorization techniques: Many questions in the bank involve numbers. Summarizing these numbers makes memorization easier. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the traffic safety laws, regulations, and related knowledge exam. Subject 2 refers to the field driving skills exam. Subject 3 refers to the road driving skills and safety and civics driving knowledge exam.

What is the appropriate tire pressure for cars in summer?

In summer, the appropriate tire pressure is around 2.3 bar. The standard tire pressure generally ranges between 2.3-2.5 bar. Due to the principle of thermal expansion and contraction, the tire pressure in summer should be set at the lower limit of the standard tire pressure, so a tire pressure of around 2.3 bar is more suitable in summer. Hazards of overinflated tires: Excessive tire pressure reduces the friction and adhesion of the tires, affecting braking performance, causing steering wheel vibration and deviation, and reducing driving comfort. It also accelerates wear on the central tread pattern, shortening tire life, increasing body vibration, and indirectly affecting the lifespan of other components. Overinflation also causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body, increasing the load on the car while driving, and decreasing puncture resistance. When encountering sharp objects on the road, the tire is more likely to be punctured, leading to internal cracks and blowouts, resulting in a tire burst. Hazards of underinflated tires: Tire pressure significantly below the standard level increases the friction coefficient between the tire and the road surface, leading to higher fuel consumption and causing heavy steering and deviation, which are detrimental to driving safety. Insufficient tire pressure increases the movement of various parts of the tire, causing excessive rolling and abnormal heat buildup, reducing the functionality of the cords and rubber, leading to delamination or cord breakage. Excessive friction between the tire and the rim can cause damage and abnormal wear to the bead area. The friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions can also lead to a tire burst.

Which gear should be used for climbing hills?

Use the L gear for climbing hills. L stands for low gear. Shifting to L gear locks the transmission between 1st and 2nd gears. When climbing, greater torque is required to propel the vehicle upward and overcome the gradient resistance. Automatic transmission generally refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on engine speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations. Typical automatic transmission cars have six gears, arranged from top to bottom as: P, R, N, D, S, L. The automatic transmission utilizes planetary gear mechanisms for shifting, automatically changing gears according to the degree of throttle pedal depression and changes in vehicle speed.

What causes the steering wheel to move left and right at low speeds?

Low-speed steering wheel movement left and right is caused by: 1. Poor driving habits of the owner, resulting from excessive braking; 2. Frequent driving on mountain roads, causing abnormal wear on the brake disc and brake pad surfaces, leading to unevenness; 3. Issues with the brake system, tires, or bearing installation; 4. Excessive braking force, causing the brake pads and discs to overheat or deform. The steering wheel is a wheel-shaped device used to control the direction of vehicles and other means of transportation. It transmits vibrations generated during driving to the driver, allowing them to control the vehicle's direction. The steering wheel mainly consists of a skeleton and foam, with the skeleton typically made of zinc alloy or aluminum alloy.
