Transmission AT stands for automatic transmission, while MT stands for manual transmission. The following are detailed introductions: 1. Automatic transmission is developed relative to manual transmission: The automatic transmission can automatically shift gears based on the vehicle speed and engine RPM. 2. The difference in composition between MT and AT: MT, also known as manual transmission, requires the driver to manually shift the gear lever to change the gear meshing device inside the transmission, which is more fuel-efficient; AT automatic transmission consists of a torque converter, planetary gear transmission, and control mechanism. 3. The working principles of MT and AT: (1) MT working principle: The pump wheel and turbine are a working pair, similar to two fans placed opposite each other. The wind blown by one fan will drive the blades of the other fan to rotate, with the wind serving as the medium for kinetic energy transmission. (2) AT does not require a clutch to shift gears, has fewer gear changes but larger variations, and provides smooth connections, making it easier to operate and more convenient for the driver.

The difference between AT and MT transmissions is significant. AT stands for automatic transmission, where you don't need to press the clutch or shift gears manually while driving. The system automatically changes gears based on vehicle speed and RPM, making it much more convenient, especially in traffic jams or during long-distance driving. For example, when I drive an AT car, it's much easier on my hands and feet, making it suitable for beginners or those who prefer convenience. MT is a manual transmission, requiring you to operate the clutch and gear stick yourself. You must press the clutch and shift gears to start and change speeds. It might feel overwhelming at first, but once you get used to it, you can better control the engine's output, offering more flexibility in situations like cornering or climbing hills. In terms of fuel consumption, AT used to consume more fuel, but with technological advancements, many new AT models are now as fuel-efficient as MT. Regarding maintenance costs, AT has a more complex structure, is more prone to issues, and replacement parts are more expensive; MT is simpler, more durable, and cheaper to repair. In summary, choose AT for convenience and MT for driving pleasure.

What Causes the Failure to Schedule a Subject One Exam?

There are two main reasons for failing to schedule a Subject One exam. First, there may be too many applicants, making it impossible to secure a slot based on the scheduling rules. Second, sufficient training hours must be completed before scheduling the Subject One exam; otherwise, the system will prompt that training has not been attended, and the exam cannot be scheduled. Passing score for Subject One: The total duration of the Subject One exam is 45 minutes. The test consists of 100 questions, including true/false and multiple-choice questions, with a maximum score of 100. A score of 90 or above is required to pass. The exam questions are randomly selected and combined by the computer-based driver's license examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Regulations." Exam procedure: Follow the staff's instructions and collect your driving training file in order at the waiting area. Carry and present your ID card for verification by the supervising officer. Mobile phones must be turned off upon entering the exam area. No loud talking is allowed in the exam area. Regulation textbooks are not allowed in the exam area (or must be placed in a bag). After the exam, keep your ID card safe and submit the file to the "Document Submission Window" at the front of the exam area. Candidates who pass the exam must sign under the guidance of the staff at the exit before leaving. Candidates who fail the exam may leave immediately and wait for their driving school to notify them of the retake schedule.

What is the wading depth of a car?

The wading depth of a car refers to the distance of the vehicle's ground clearance. The greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Below is relevant information about the minimum ground clearance of a car: 1. Definition: The standard for "minimum ground clearance" is GB/T3073.3-1993, defined as the distance between the most protruding part of the chassis and the horizontal ground when the car is fully loaded (allowing maximum load mass). The minimum ground clearance reflects the car's ability to pass obstacles or uneven ground. 2. Range: The greater the minimum ground clearance, the stronger the vehicle's ability to pass obstacles or uneven ground, but the higher the center of gravity, reducing stability; the smaller the minimum ground clearance, the weaker the vehicle's ability to pass obstacles or uneven ground, but the lower the center of gravity, which can increase stability.

Should Front and Rear Brake Pads Be Replaced Together or Separately?

Front and rear brake pads do not need to be replaced together, as they have different replacement cycles. Compared to front brake pads, rear brake pads have a longer service life. Under normal driving conditions, front brake pads typically require replacement every 30,000 to 50,000 kilometers, while rear brake pads can last around 60,000 to 100,000 kilometers before needing replacement. Below is relevant information about brake pads: Replacement Timing: There is no fixed time for replacing brake pads; the above figures are only approximate. The replacement cycle of brake pads is not only directly related to their service life but also depends on the vehicle's driving conditions and the driver's habits. New brake pads are approximately 1.5 centimeters thick. When they wear down to about one-third of their original thickness, or around 5 millimeters, they should be replaced promptly. When replacing brake pads, both pads on the same axle should be replaced together to ensure balanced braking performance on both sides. Materials: Brake pads are currently made from materials such as asbestos, high-carbon fiber, semi-metallic, ceramic, and others. Asbestos brake pads have been phased out, with semi-metallic and ceramic being the most common today. Semi-metallic pads are more affordable and widely used in household vehicles. Ceramic pads, on the other hand, offer better performance than metallic ones—they are more wear-resistant, heat-stable, and dissipate heat quickly, with a higher friction coefficient. However, they are also more expensive and are typically used in mid-to-high-end vehicle models.

Is there no vehicle photo on the driving license now?

Driving licenses generally include a vehicle photo, so a driving license without a vehicle photo is abnormal and requires timely replacement of the vehicle photo at the vehicle management office. The following is relevant information about the vehicle driving license: 1. Application: The driving license can be processed at the traffic management department of the public security authority or the local vehicle management office. You need to bring your ID card and the vehicle purchase invoice to complete the application. 2. Importance: The driving license is important as it serves as the vehicle's ID card, used to identify the vehicle's status, whether it can be driven on the road, and whether it is a qualified motor vehicle. 3. Legal provisions: Article 17 of the "Road Traffic Management Regulations" promulgated by the State Council stipulates that vehicles must pass the inspection by the vehicle management authority, obtain license plates and a driving license before they are allowed to drive.

Is it considered hit-and-run if the other party scratches my car and flees?

Is it considered hit-and-run if the other party scratches my car and flees: If a party scratches another person's car and then flees the scene, it falls under the circumstances specified in Article 3 of the "Interpretation of the Supreme People's Court on Several Issues Concerning the Specific Application of Law in the Trial of Criminal Cases of Traffic Accidents"; this constitutes hit-and-run. In the event of a traffic accident, if a party flees, the fleeing party bears full responsibility. However, if there is evidence proving that the other party was also at fault, the responsibility may be reduced. If a party intentionally destroys, falsifies the scene, or destroys evidence, they bear full responsibility. Scratching someone else's car and fleeing is considered a hit-and-run act. After a traffic accident occurs, any act of fleeing to evade legal consequences is considered hit-and-run. According to Article 70 of the "Road Traffic Safety Law of the People's Republic of China," in the event of a traffic accident on the road, the driver of the vehicle must immediately stop and protect the scene. If there are personal injuries or fatalities, the driver must immediately rescue the injured and promptly report to the on-duty traffic police or the traffic management department of the public security organ. If the scene is altered due to rescuing the injured, the original positions must be marked. Passengers, drivers of passing vehicles, and pedestrians should assist. In the event of a traffic accident on the road that does not result in personal injuries or fatalities, if the parties involved have no disputes over the facts and causes, they may immediately leave the scene, resume traffic, and negotiate compensation matters on their own. If they do not leave the scene immediately, they must promptly report to the on-duty traffic police or the traffic management department of the public security organ. In the event of a traffic accident on the road that only causes minor property damage and the basic facts are clear, the parties involved should first leave the scene and then negotiate. Article 71 states that if a vehicle flees after a traffic accident, eyewitnesses and other informed individuals should report to the traffic management department of the public security organ or the traffic police. If the report is verified, the traffic management department of the public security organ should provide a reward.

How many kilometers should a new car change its oil?

Generally, a new car should have its oil changed every six months or 5,000 kilometers. Below is relevant information about car engine oil: 1. Importance: Engine oil is crucial for the engine. It not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat. 2. Working principle: When the engine is running, the oil forms a film on the surfaces of various components inside the engine, preventing direct contact and friction between these parts. 3. Regular replacement required: The performance of engine oil decreases over time, so it needs to be changed regularly. If the oil is not changed for a long time, it can accelerate engine wear.
