How many questions are there in Driving Test Subject 4?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's 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 test 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 hand signals; accident rescue and hazardous material handling knowledge; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving knowledge; and driving ethics and civilized driving knowledge. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," Subjects 1 and 4 have no limit on the number of test attempts. 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 invalidated. Subject 4, also known as the Subject 4 theory test 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, Subject 3 was divided into two parts: the road test and the addition of a safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Subject 4 is the colloquial term for the Subject 3 safety and civilized driving knowledge test. It is not a separate subject but is commonly referred to as Subject 4 because it is conducted after Subject 3. Officially, there is no Subject 4. The safety and civilized driving knowledge test is conducted after Subject 3. Subject 4 Test Notes: Test Duration: The test lasts 45 minutes. If 10 points (5 questions) are answered incorrectly during the test, the session 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, with each question worth 2 points. Question Types: The test includes single-choice questions (including true/false questions) and multiple-choice questions, with questions presented as animations, images, scenario recognition, or text descriptions. 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 on the number of retakes. Retakes for Subject 4 do not require additional fees. 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 examination of road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge test.

How to Replace the Antifreeze in a Bora?

The tutorial for replacing the antifreeze in a Bora is as follows: 1. Drain the coolant: First, open the reservoir cap (ensure the radiator cap is tightly sealed), then unscrew the drain switches on the cylinder block and radiator. This should be done while the engine is running at low speed and is warm. 2. Add new coolant. Precautions for replacing the antifreeze are as follows: 1. After the coolant is completely drained, tighten the drain switches on the cylinder block and radiator. 2. Close the radiator cap, let the engine run until it reaches normal operating temperature, then turn it off and wait until it cools to room temperature. 3. Observe the liquid level in the reservoir and add coolant as needed until no air bubbles appear in the reservoir when the engine is idling. 4. Fill the radiator with the specified coolant through the filler port until the liquid level in the reservoir reaches the designated "MAX" mark.

How to Remove the Glove Box in a Magotan?

Removing the glove box in a Magotan is quite simple. There are three screws at the bottom of the glove box. After unscrewing these three screws, open the glove box to find five more screws inside. Remove them one by one to take out the glove box. Here are more details about the glove box: 1. Generally, the glove box is removed to replace the cabin air filter. The cover of the air filter box is secured with a clip. Gently push the clip aside to remove the cover and access the filter. The filter has a pull tab; a gentle tug will bring it out. Install the new cabin air filter in the same orientation as the old one, paying attention to the installation direction. 2. There are two types of glove box designs: fixed and flip-down. The fixed type features an inner compartment as part of the glove box, with the storage space located within the dashboard structure. The flip-down type, on the other hand, integrates the inner compartment with the door panel, placing the storage space on the door itself. When the door is opened, the inner compartment flips out along with it. 3. The flip-down design generally makes it easier for users to access items inside. However, because additional structures are required on the door panel, it reduces the available internal space of the glove box, which is less ideal for storing items or installing internal components like glove box lights. Conversely, the fixed type offers more space but is less convenient for front-seat occupants to access items.

Who Invented the Rotary Engine?

The German engineer Felix Wankel produced the world's first rotary engine in 1957 and obtained the patent. However, currently only the Japanese automaker Mazda is conducting research on it. Below are specific details about the rotary engine: 1. The rotor of a rotary engine performs work once per rotation. Compared to a conventional four-stroke engine, which performs work once every two rotations, it has the advantage of a high power-to-displacement ratio (the engine can output more power with a smaller displacement). 2. Due to the axial operation characteristics of the rotary engine, it can achieve higher operating speeds without requiring a precisely balanced crankshaft. The entire engine has only two rotating components, which greatly simplifies the structure compared to a conventional four-stroke engine with over twenty moving parts, such as intake and exhaust valves, significantly reducing the likelihood of failure. In addition to the above advantages, the rotary engine also features a smaller size, lighter weight, and a lower center of gravity.

Is There Water in the Exhaust Pipe in Winter?

In winter, there is water in the exhaust pipe because gasoline produces water and carbon dioxide after complete combustion. Here are the reasons why water dripping from a car's exhaust pipe is normal: 1. Correct air-fuel mixture ratio: When the vehicle's air-fuel mixture ratio is correct, water dripping from the exhaust pipe is normal. Whether it's an electronic fuel injection or carburetor engine, a correct air-fuel mixture ratio indicates that the vehicle's compression ratio is normal, and fuel consumption is within the normal range. 2. Normal engine cylinder pressure: When water drips normally from the vehicle's exhaust pipe, it indicates normal engine cylinder pressure, showing that there is no wear in the engine cylinder block and that all parts inside the engine are working properly. This method can be used to determine whether the fuel is burning normally. 3. Normal exhaust temperature: Normal water drainage from the vehicle's exhaust pipe also indicates that the exhaust temperature is normal, meaning the engine's power output is stable.

What Are Some Clever Methods for Repairing Small Dents on Car Doors?

Here are specific methods for repairing small dents on car doors: 1. Manual Repair: Prepare construction tools, including various lever tools, professional lighting, repair hammers, and specialized leveling pens. For car dent repair, tools are not the most important; what matters most is the technician's skill, attention to detail, and patience. 2. Car Dent Repair Construction: Use the visual effect of light refraction to determine the position and extent of the dent. Apply the principle of leverage to massage the internal 'skin' of the car body, gradually releasing the tension at the dented area. This maximizes the 'entropy' value on the surface of the door dent, restoring it to its original shape, achieving fast, accurate, and complete repair of the car body dent. 3. Light-Facing Repair: Check the repair effect by facing the light or sunlight. If no flaws are visible, the repair is considered successful.
