How Many Chances Are There to Take the Subject 4 Exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of times you can take the Subject 4 exam. If you fail the first attempt on the same day, you can retake it once on-site. If you still fail, you need to reschedule the exam, and no additional fees are required for the retake. 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 exam within the validity period, the results of any previously passed subjects will be invalidated. 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 driving 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 3 exam was divided into two parts: the road test and an additional safety and civics knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Subject 4 is the colloquial term for the safety and civics 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 exam. 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 30 minutes. Number of Questions: Depending on the type of license being tested, 50 questions are randomly selected from the corresponding 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, with questions presented as animations, images, scenario recognition, or text descriptions. Subject 4 Exam Tips: Focus on error-prone areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answers. Instead, consult regulations, textbooks, or reference materials to understand and internalize the reasons for errors. 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 grouped. For example, traffic signs for walking, hiking, pedestrian caution, crosswalks, and crosswalk caution are very similar and easily confused. During study, group them together to avoid mistakes. Find memorization techniques: Many questions in the bank involve numbers. Summarize these numbers to make them easier to remember. There are three subjects in the driving test: 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 civics driving knowledge test.

Are There Subsidies for Scrapping New Energy Vehicles?

New energy vehicles do have subsidies for scrapping. Below is the extended content regarding the scrapping of new energy vehicles: 1. For new energy vehicles, the scrapping standards are entirely based on those for existing fuel-powered vehicles. Since new energy vehicles have no tailpipe emissions, the scrapping standard for non-commercial small and micro new energy vehicles is measured at 600,000 kilometers. According to the battery recycling management regulations, they are typically scrapped after about 5 to 8 years. 2. There is no separate scrapping standard for new energy vehicles. As long as the vehicle can pass the annual inspection smoothly without any issues, it can continue to be used; otherwise, it needs to be scrapped. Regarding the new regulations on the scrapping period for family vehicles, the current standard mileage for private cars is around 600,000 kilometers. After reaching 600,000 kilometers, the vehicle should be scrapped under national guidance.

What Should Be Noted in New Energy Vehicle Maintenance?

When maintaining a new energy vehicle, the following points should be noted: 1. Correctly grasp the charging time. Avoid over-discharging, and the charging time should not be too long. Overcharging can cause the battery to heat up and shorten its lifespan. 2. Protect the charger. During charging, ensure the charger is well-ventilated; otherwise, it may affect the charger's lifespan and potentially damage the battery. 3. Maintain sufficient power. After daily use of the new energy vehicle, necessary charging is required to keep the car battery fully charged. 4. Cleaning the electric vehicle. When cleaning, be careful to prevent water from entering the charging socket inside the vehicle and ensure waterproofing. 5. Keep the power sufficient. Maintain the battery's charging state and control the vehicle speed. 6. Avoid overheating of the plug during charging. Loose power plugs or charger output plugs, oxidized contact surfaces, and other phenomena can cause the plug to overheat. Prolonged overheating may lead to short circuits or poor contact, damaging the charger and battery.

What does in-car monitoring mean?

In-car monitoring is a system used to detect life signs inside the vehicle. Here are the specific details: 1. Infrared monitoring: First, let's talk about the infrared detection solution. Many overseas brands install infrared sensors in vehicles for anti-theft purposes. Once the vehicle is locked, the infrared sensors activate immediately. If any heat source enters the vehicle, it triggers an alarm. 2. Fatigue monitoring: Currently, many vehicles are equipped with cameras to detect driver fatigue. After the vehicle is locked, these cameras can monitor vital signs. 3. Gravity monitoring: Now, let's discuss the gravity sensor. Most modern vehicles have gravity sensors installed in the seats to determine whether passengers have fastened their seat belts.

What Causes Exhaust Pipe Shaking?

Engine idle exhaust pipe shaking, also commonly referred to as exhaust pipe trembling, shaking, or jumping during idle. The following are the reasons for engine exhaust pipe shaking: 1. Flexible Joint: The exhaust pipe and engine are connected by a flexible joint. It may be due to the flexible joint being damaged after prolonged use of the vehicle. 2. Rubber Rings: The exhaust pipe and frame are connected by several rubber rings. You can check if the rubber rings are damaged or if there is a problem with rubber aging. 3. Seals: There are seals between the exhaust pipe and the flexible joint, and between the flexible joint and the engine. You can check if the seals are damaged.

Can Sprite Bottles Be Used to Store Gasoline?

Sprite bottles cannot be used to store gasoline. Below is relevant information about automotive gasoline: 1. Overview: Automotive gasoline is a liquid fuel refined from petroleum, primarily used for cars and motorcycles. 2. Classification: In China, automotive gasoline is divided into unleaded and leaded types. Unleaded gasoline comes in three octane ratings: 90, 93, and 95 RON (Research Octane Number). Leaded gasoline also has three octane ratings: 90, 93, and 97 RON. Among these, 90-octane gasoline contains no more than 0.35g/L of lead, while 93-octane and 97-octane gasoline contain no more than 0.45g/L of lead.
