Is Subject 4 the same as Subject 3's Safety and Civilization Knowledge?

Subject 3's Safety and Civilization Driving Knowledge Test is commonly referred to as Subject 4. Subject 4, also known as Subject 4 Theory Test or Driver Theory Test, is part of the motor vehicle driver's license assessment. It primarily includes: safety and civilization driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-traffic accident handling knowledge. The Subject 4 test consists of 50 questions, presented in formats such as case studies, images, and animations, with a full score of 100 and a passing score of 90. 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 known as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is commonly referred to as Subject 4. Officially, there is no such term as Subject 4. Before the test, students can study traffic regulations through driver simulation test software on mobile devices or computers.

How much fuel is consumed per kilometer?

Generally, a car consumes about 0.07L of gasoline per kilometer. Here are some related introductions: 1. Introduction to gasoline: Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, and can be used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of approximately 30°C to 220°C. 2. Differences in fuel consumption: Poor driving skills can lead to increased fuel consumption. The same car driven by different people will have different fuel consumption levels. Only by summarizing experiences and improving driving skills can the problem of high fuel consumption due to driving techniques be resolved.

What Does It Mean When the Air Suspension Warning Light Comes On?

The reasons for the air suspension warning light coming on are as follows: 1. Air suspension system leakage: The fault manifests as the vehicle body tilting or the front/rear air suspension dropping to its lowest position after the vehicle has been parked for a period of time. If the air suspension suddenly leaks excessively, it may result in the air suspension becoming unadjustable (due to the air compressor shutting down because of overheating). Air spring leakage can also be tested by applying compressed air to the air spring assembly submerged in water for pressure testing. Generally, workshop compressed air pressure does not exceed 800kPa, which will not damage the air spring itself. 2. Air suspension unable to adjust height: The fault manifests as the air suspension failing to raise or lower according to the driver's preference, possibly accompanied by the illumination of the air suspension warning light on the instrument panel.

Can a tire used for one day be returned?

Generally, a tire used for one day cannot be returned. The functions of tires are as follows: 1. Load-bearing: Supports the entire weight of the vehicle and bears the load of the car. 2. Torque: Transmits traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power performance, braking performance, and passability. 3. Damage prevention: Protects automotive components from severe vibrations and early damage, adapts to the vehicle's high-speed performance, reduces noise during driving, and ensures driving safety, handling stability, comfort, and energy efficiency. Tires are circular elastic rubber products assembled on various vehicles or machinery, mounted on metal rims, and characterized by high wear resistance.

Why does Subject 4 show as failed without taking the exam?

Subject 4 shows as failed without taking the exam due to system operation errors or failure to attend the officially scheduled exam. Below are detailed explanations of the reasons: System operation error leading to failure: Because there are many people in the examination room, the network may be slow, possibly causing delays or system instability. If submission is successful, you can ask the staff what happened, whether everyone is experiencing this or only a few individuals. If only a few are affected, you can ask the staff whether a retest is necessary. Failure to attend the officially scheduled exam leading to failure: If you have scheduled Subject 4 but did not attend the exam, you can only reschedule the exam. According to regulations, if a student fails to attend the exam at the scheduled time, they must apply to cancel the appointment one day in advance; if the appointment is not canceled as scheduled and the exam is not attended, the exam will be marked as failed; students who fail must retake the exam; the previously scheduled fee will not be refunded; the retake fee must be paid separately; there is no limit to the number of times Subject 4 can be taken. You can also negotiate with the driving school, explain the actual difficulties, and ask the driving school to help schedule Subject 4, but during this period, you must review Subject 4 thoroughly.

Are electric vehicles exempt from purchase tax?

Electric vehicles are exempt from purchase tax. The new energy vehicles exempt from vehicle purchase tax include pure electric vehicles, plug-in hybrid (including range-extended) vehicles, and fuel cell vehicles. The scope of vehicle purchase tax includes cars, motorcycles, electric vehicles, tractors, and agricultural transport vehicles. There are three payment methods for purchasing pure electric vehicles: full payment, deposit payment, and mortgage payment. When paying for the vehicle, the following documents are required: ID card, and the dealer provides "vehicle sales invoice," "vehicle warranty manual," and "vehicle user manual." The purchase invoice must be stamped with a business verification seal at the local Industrial and Commercial Bureau's motor vehicle market management office or a designated agent at the car trading market. Before obtaining the official license plate, the vehicle can only be driven on the road with a temporary movement permit. All new vehicles must be inspected at the testing site and obtain a temporary license plate before being allowed on the road. The temporary license plate must be prominently displayed on the front windshield of the new vehicle. Insurance must be purchased before obtaining the license plate. Car trading markets have insurance company agents, and completing the insurance procedures at the time of purchase can save future trouble. New vehicles must have compulsory traffic insurance. Precautions for purchasing pure electric vehicles: Check the range. When buying an electric vehicle, it is important to consider the range. The longer the range, the more suitable it is, as it affects convenience of use. Check the brand's quality. When buying an electric vehicle, it is advisable to choose a reputable brand to ensure quality and reliable after-sales maintenance. Check charging time and convenience. Generally, charging is a major issue for electric vehicles, so it is important to clarify the charging time. Electric vehicles are usually divided into slow charging and fast charging, so it is better to choose one with a shorter charging time.
