Why Does Subject Four Show as Subject Three?

What Should Be Included When Buying a Car?

Typically, when purchasing a car, some dealerships may offer sun films, which are divided into full-body and partial-body options, both being quite practical. In addition to sun films, some dealerships might also provide floor mats or carpets, which help maintain cleanliness inside the vehicle. Furthermore, mud flaps might be included as a practical accessory. Other possible gifts include trunk waterproof mats, cargo nets, seat covers, engine guards, and for higher-end vehicles, even satellite navigation devices. Here are some points to note about these complimentary items: 1. Steering wheel covers: First on the list are steering wheel covers. Among car accessories, these are merely decorative and offer little functional benefit for driving. If a low-quality steering wheel cover is used, its low friction coefficient may cause it to slip during steering, leading to imprecise control and potential hazards in emergencies. 2. Sun films: Many car owners apply sun films to their car windows after purchasing a new vehicle, primarily for sun protection and privacy in the cabin. While offering sun films is a common sales tactic by 4S shops, the quality of these films often has flaws, with the most noticeable issue being a strong odor. 3. Car ornaments: To cater to some owners' preferences for decorating their car interiors, some 4S shops may offer hanging or dashboard ornaments. However, placing items near the dashboard can obstruct the deployment of airbags in emergencies. Additionally, during severe jolts, these ornaments can easily injure the vehicle's occupants.

What are the contents of the Driver's License Subject 4 exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the Subject 4 exam consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. 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, the Subject 3 exam was divided into two parts: the road test and the addition of the safety and common sense test, commonly referred to as Subject 4. This is not a separate subject but is called 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. There is no limit to 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 retake fee is required. However, it is important to note that the validity period of the driving skills test permit is three years. If the applicant does not complete the exam within the validity period, the results of the previously passed subjects will be invalidated. Subject 4 exam notes: Exam duration: The exam lasts 45 minutes. If you answer 10 points (5 questions) incorrectly during the test, the exam will be terminated. Number of questions: Depending on the type of driver's license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank in proportion. Both small vehicle and large vehicle licenses draw questions from the same bank. 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 questions include animation-based 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 to the number of retakes. No retake fee is required for Subject 4. Subject 4 exam tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answer. Refer to regulations, textbooks, or reference books to understand the reasons for errors and internalize them. Categorize and summarize 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 and summarized. For example, traffic signs for walking, hiking, pedestrian crossing, and pedestrian crossing warnings are very similar and easily confused. During study, categorize them to avoid mistakes. Find memorization techniques: Many questions in the bank involve numbers. Summarizing these numbers can make 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 road 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 civilized driving knowledge exam.

How to Determine the Quality of Spark Plugs?

Spark plugs exhibit the following symptoms when they may be faulty: Difficulty starting the car, both during cold starts and hot starts, often requiring multiple attempts. Engine shaking, where the car experiences vibrations while driving. Reduced power, noticeably weaker performance compared to normal conditions. Increased fuel consumption. Stalling issues. Failed exhaust emissions. Common causes and diagnosis of spark plug failures: Several common issues can cause spark plugs to malfunction: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture and suppresses flame kernel growth due to the quenching effect of the electrodes, resulting in weak sparks and difficulty igniting the mixture. A gap that is too large may exceed the ignition system's voltage capacity, preventing a spark from jumping between the electrodes. Cracked spark plug skirt. High-voltage current leaks through the crack, preventing sparks from jumping between the electrodes. Carbon buildup on the electrodes, causing leakage from the center electrode to the surrounding area instead of jumping to the side electrode. Excessive carbon deposits can short-circuit the spark plug, preventing sparks and damaging the insulator. Damaged electrodes. Prolonged electrical erosion from sparks or chemical corrosion from combustion gases can cause electrodes to break or detach, preventing sparks. Low insulation resistance of the spark plug. This reduces the ignition voltage applied to the spark gap, weakening or completely disabling the spark. Short circuit in high-voltage wires. Leakage in the wire from the ignition coil to the distributor can prevent the entire engine from starting, while leakage in the wire from the distributor to the spark plug can prevent a single cylinder's spark plug from firing. Eroded platinum contacts. This can cause all spark plugs to fail, preventing the engine from starting or running normally. Faulty spark plugs should be replaced promptly. The replacement steps are as follows: Open the engine hood, remove the plastic cover, and disconnect the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug, ensuring the surrounding area is free of debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it a few turns, and then use the socket to tighten it fully. Reinstall the high-voltage wires in the correct firing order and reattach the cover. Spark plug replacement interval: Typically, spark plugs should be replaced every 40,000-60,000 km under normal maintenance conditions, but this may vary by brand and engine type. Always refer to the owner's manual for specific recommendations.

How Many Chances Are There for the Driving Test Subject 4?

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 4. If the first attempt on the 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 the validity period, the results of any previously passed subjects will be voided. Subject 4 consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. Subject 4, 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, Subject 3 was divided into two parts: the road test and the safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "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 Test Notes: Test Duration: The test lasts 30 minutes, and the test will be terminated if 12 points (6 questions) are answered incorrectly during the test. Number of Questions: Depending on the type of license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank. For car licenses, questions are selected from 800, and for large vehicle licenses, from 1,023, with each question 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 animated questions, image-based questions, scenario identification 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. Unsuccessful candidates can retake the test indefinitely, and no additional fees are required for Subject 4 retakes. Subject 4 Test Tips: Strengthen Weak Areas and Identify Mistakes: For marked questions, do not just look at the correct answer and memorize it. Instead, consult regulations, textbooks, or reference materials to understand the reason for the mistake and internalize it. Categorize and Summarize Questions: Refer to the question bank analysis for categorization and identify similar questions. Many questions in the bank are similar and can be confusing, so they should be analyzed and summarized. For example, traffic signs for walking, hiking, pedestrian attention, crosswalks, and crosswalk attention have similar patterns and can be confusing. Grouping them during study can help avoid mistakes. Find Memorization Techniques: Many questions in the bank involve numbers. Summarizing these numbers can make memorization easier. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 3 is 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. Subject 3 refers to the road driving skills and safety and civilization driving knowledge test.

What is the gap of a spark plug?

The gap of a spark plug ranges between 0.6mm and 1.3mm. The spark plug gap refers to the distance between the center electrode and the ground electrode. A larger spark plug gap produces a longer arc during ignition, which makes it easier to ignite the air-fuel mixture in the cylinder, resulting in greater kinetic energy. However, since a larger gap requires a higher voltage to break down the air during ignition, different engines are matched with spark plugs of varying gaps. Choosing the correct spark plug gap ensures optimal engine performance. The size of the spark plug gap significantly impacts the vehicle, and the requirements for the gap vary depending on the engine model, driving habits, and road conditions.

What are the differences between license plates for pure electric and hybrid vehicles?

Pure electric and hybrid vehicles have different license plate colors: pure electric vehicles, classified as new energy vehicles, have license plates with a green background; hybrid vehicles, categorized under fuel-powered vehicles, have license plates with a blue background. Specifically, small new energy passenger vehicles use gradient green plates, while large new energy passenger vehicles use yellow-green dual-color plates. License plates, commonly referred to as vehicle plates, are panels mounted on the front and rear of a vehicle. They serve as identification and registration for each vehicle, primarily enabling recognition of the vehicle's region of registration and allowing access to the owner's details and registration information based on the plate.
