What is the mesh in front of a car called?

The mesh-like component at the front of a car is called the car grille, radiator grille, or radiator cover. The metal grille (Grille), also known as the car front face, radiator grille, or radiator cover, primarily serves to allow air intake for the radiator, engine, and air conditioning system. It also protects internal components from damage caused by foreign objects during driving and enhances the car's aesthetic appeal. As the window for supplying air to the engine, the intake grille is usually located behind the car grille and directly in front of the engine compartment. Its main functions are heat dissipation and engine air intake. Generally, the car's "front gate" remains open, allowing outside air to freely enter. This means that during cold driving, the already low-temperature radiator is further cooled by the outside air, causing the water temperature to rise very slowly. As a result, the engine takes longer to reach its optimal operating state. Many car models experience slow and significantly reduced heating effects in winter due to this. The car's heating system does not rely on a compressor or electric auxiliary heating, with only a very few electric vehicles using the compressor's heat pump system for auxiliary heating. In fuel-powered cars, the warm air comes from the "residual heat" of the engine operation. This heat warms the antifreeze coolant, and when the heating is turned on, a valve connected to the water cooling system opens, allowing the high-temperature antifreeze to flow into the heater core and heat up. The blower then blows cold air over the high-temperature heater core, heating the air through the principle of heat absorption by lower-temperature objects. This is the principle of heating. If the temperature is too low and the vehicle is moving, the cold air will excessively absorb heat from the engine's radiator, preventing the internal antifreeze coolant from reaching a high temperature. This description might seem exaggerated, but it's a fact. Some trucks in northern regions used to cover the front with a leather blanket. This leather served as a "windshield," similar to the windshields used on electric bikes to cover the legs, aiming to prevent cold wind from contacting the engine radiator. Excessively low temperatures can indeed prevent the engine from reaching its optimal operating temperature, leading not only to the inability to use the heating system but also to the engine failing to achieve the ideal temperature required for optimal thermal efficiency, resulting in increased fuel consumption.

How Many Questions Are There in Driving Test Subject 4?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," Subject 4 consists of 50 questions, each worth 2 points, totaling 100 points. Questions 1-10 are true/false questions; questions 11-40 are single-choice questions; and questions 41-50 are multiple-choice questions. The exam includes question types such as image analysis, animated case studies, and text descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and gestures; accident rescue and hazardous material handling; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving knowledge; and driving ethics and civilized driving awareness. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of attempts for Subject 1 and Subject 4. If the first attempt on the same day is unsuccessful, an immediate retake is allowed. If the retake is also unsuccessful, a new appointment must be made, 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 test within this period, the results of any previously passed subjects will be voided. Subject 4, also known as the Subject 4 theory 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, Subject 3 was divided into two parts: the road test and the safety and civilization knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Subject 4 is the colloquial term for the safety and civilization driving knowledge test under Subject 3 and is not a separate subject. Since this test is conducted after Subject 3, it is commonly called the Subject 4 test. Officially, there is no "Subject 4." The safety and civilization driving knowledge test is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes. If 12 points (6 questions) are incorrect 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 in proportion. For car licenses, questions are drawn from a pool of 800, while for large vehicle licenses, they are drawn from a pool of 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 animated questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the retake, and there is no limit to the number of retakes. No additional fees are required for Subject 4 retakes. 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 road 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 civilization driving knowledge test.

What documents are needed for the make-up test of Subject 1?

For the test, only an ID card is required. The admission ticket and other documents are handled by the driving school, which will distribute them during the test. Electronic IDs cannot be used for the test. If you don't have an ID card, you can apply for a temporary one, which holds the same validity as a formal ID card. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," you can take the Subject 1 test twice on the same day. If you fail the first attempt, you can retake it for free. If you fail the second attempt, the Subject 1 test will be terminated, and you can only reschedule after ten days. The Subject 1 test consists of 100 questions, including single-choice and true/false questions, each worth 1 point, totaling 100 points. If you answer 11 questions incorrectly during the test, the system will automatically submit the paper and end the test. The Subject 1 test is computer-based and lasts 45 minutes. The content of the Subject 1 test includes: regulations on driving licenses and motor vehicle management; road traffic conditions and regulations; traffic safety violations and penalties; regulations on road traffic accident handling; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Notes for the Subject 1 test: Candidates should pay attention to their attire—no slippers are allowed. Electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Upon entering, the identity verification desk will assign a seat. After finding your seat, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, you can retake it the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score sheet and sign it.
