According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the subject four test consists of 50 questions, primarily in the form of case studies, images, animations, etc., with a full score of 100 and a passing score of 90. Subject four, also known as the theoretical test or driver theory test, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the subject three test was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as subject four. It is not a separate subject but is called subject four because it is conducted after subject three. Officially, there is no subject four. The safety and civilized driving knowledge test is conducted after subject three. There is no limit to the number of attempts for the subject four test. If the first attempt on the day is not passed, an immediate retake is allowed. If it is still not passed, a new appointment is required, and no retake fee is charged. However, it is important to note that 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 previously passed subjects will be invalidated. Subject four test considerations: Test duration: The test lasts 30 minutes, and if 12 points (6 questions) are answered incorrectly during the test, the session will be terminated. Number of questions: Depending on the type of driving license being tested, 50 questions are proportionally selected from the corresponding subject four question bank. For small vehicle licenses, questions are selected from 800, and for large vehicle licenses, from 1023. Each question is worth 2 points. Question types: The test 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 test also includes animation questions, image questions, scenario recognition questions, and text-based questions. Retake considerations: If subject four is not passed, only subject four needs to be retaken. The driving school will schedule the retake, and there is no limit to the number of retakes. No retake fee is required for subject four. Subject four test tips: Strengthen weak areas by identifying the reasons for mistakes. For marked questions, do not just look at the correct answer and memorize it. Refer to regulations, textbooks, or reference books to understand the reasons for errors and digest them. Categorize and summarize test questions. Refer to the question bank analysis for classification and find similar questions: Many questions in the bank are similar and easily confused, so they should be analyzed collectively. For example, traffic signs for walking, hiking, pedestrian caution, crosswalks, and crosswalk caution are very similar and easily mixed up. Grouping them during study helps avoid mistakes. Find memory techniques: Many questions in the bank involve numbers. Summarizing these numbers can make memorization easier. There are three subjects in the driving test: subject one, subject two, and subject three, with subject three divided into two parts. Subject one refers to the test on road traffic safety laws, regulations, and related knowledge; subject two refers to the field driving skill test; and subject three refers to the road driving skill and safety and civilized driving knowledge test.

I just passed the DMV written test (Subject 4), and it's still fresh in my mind! Subject 4 is actually the Safe and Civilized Driving Knowledge Exam. Unlike hardcore skills like parallel parking, it tests your understanding of road safety knowledge and behavioral norms. The questions cover traffic regulations, such as how far to stop at a red light and speed limits on highways; civilized driving practices include yielding to pedestrians, avoiding unnecessary honking, and preventing road rage; as well as emergency handling, like what to do if a tire blows out or braking precautions in rainy weather. The content is quite comprehensive, consisting entirely of multiple-choice and true/false questions completed on a computer. During preparation, I used apps for practice questions, studied traffic rule books, and tried to connect the material with real driving experience. What I appreciate most is how it reinforces safety awareness—there are so many variables on the road, and knowing these rules helps prevent accidents while protecting yourself and others. Passing this exam means you can get your driver's license, but don’t just study for the test—this knowledge is extremely practical for everyday driving.

How Many Kilograms Does 1 Liter of Gasoline Equal?

In fact, China's gasoline prices were once calculated in units of "kilograms" and "liters." At that time, China only had 66-grade and 70-grade gasoline. In terms of price, it was about 0.1 yuan per kilogram, and gasoline coupons were used at the time. After China joined the WTO, to align with international standards, the measurement units were gradually unified, designating "liters" as the legal unit of capacity, while "gong liters" and "li liters" became commonly used non-legal units (1 liter equals 1 gong liter). Converting "liters" to "jin" or "kilograms" is relatively more complex. According to China's current gasoline standards, gasoline can be classified into 92, 95, and 98 grades. Generally, the average density of 92-grade gasoline is 0.72 g/ml, 95-grade is 0.725 g/ml, and 98-grade is 0.737 g/ml. Based on the formula "mass equals density multiplied by volume," the mass per liter of 92-grade gasoline is 0.72 kg, 95-grade is 0.725 kg, and 98-grade is 0.737 kg. Taking 92-grade gasoline as an example, 1 liter of gasoline roughly equals 1.44 jin. At the current price of 7.05 yuan per liter for 92-grade gasoline in Guangdong, the price per jin of gasoline is approximately 4.9 yuan, which is a far cry from the "0.1 yuan per kilogram" price back then. Different climates in different seasons can cause slight variations in the density of substances. At a temperature of 25°C, the average densities of the major gasoline grades are as follows: assuming 89-grade gasoline has an average density of 0.72 g/ml, 92-grade gasoline has a density of 0.725 g/ml, and 95-grade gasoline has a density of 0.737 g/ml. Since 1 liter equals 1,000 ml, multiplying each density by 1,000 and converting to kilograms gives approximately 0.72 kg for 1 liter of 89-grade gasoline, 0.725 kg for 92-grade, and 0.737 kg for 95-grade. In summary: the conversion between density, liters, and kilograms is density multiplied by 1,000 equals kilograms, and kilograms divided by density equals the number of liters.

Which Air Setting to Use for Defogging Car Windows?

Both warm and cold air in a car can be used to defog windows. Here are some related tips for defogging: 1. In cold weather, it is recommended to use warm air for defogging. The method is to first turn on the air conditioning, set the temperature to warm air mode, and switch the air conditioning to the defogging setting. The hot air produced by the air conditioning will dry the fog inside the car. 2. Most modern car air conditioning systems come with a dehumidification function. Therefore, you can turn on the cold air dehumidification mode in the car, which will quickly and effectively dissipate the fog on the windows. However, when initially using warm air for defogging, the fogging may temporarily worsen, but it will improve shortly. Therefore, if conditions permit, it is better to use warm air defogging when the car is parked.

What are the uses of cruise control?

Cruise control maintains the vehicle speed as required by the driver. After turning on the switch, it automatically keeps the speed without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. Here are some introductions about cruise control: 1. The principle of the cruise control system mainly involves the cruise control component reading the pulse signal from the speed sensor and comparing it with the set speed. Through precise electronic calculations, it issues commands to ensure the most accurate fuel supply at the set speed. 2. The cruise control controller is generally located near the steering wheel and is mainly divided into lever-type, steering wheel button-type, and steering wheel control group-type.
