A torque converter is composed of a pump impeller, turbine, and stator. The pump impeller is connected to the drive shaft, and its working principle is: when the engine is running, it drives the torque converter's housing and pump impeller to rotate together. The hydraulic oil inside the pump impeller, under the action of centrifugal force, flows from the outer edge of the pump impeller blades to the turbine, then along the turbine blades to the stator, and finally back to the inner edge of the pump impeller blades through the stator blades, forming a circulating fluid flow. The torque converter is a component that transmits power through the high-speed movement of liquid. Its working characteristics are: the speed and torque at the input end are basically constant, while the speed and torque at the output end can be greater than, equal to, or less than those at the input end. Moreover, the relationship between the output speed and output torque can automatically and continuously adjust according to the load of the driven working machine.

Is lane changing penalized with points?

Lane changing incurs a 3-point penalty and a fine of 200 yuan. Additional information is as follows: 1. Handling of violation points: Currently, when dealing with vehicle violations, the owner must bring their driver's license and vehicle registration to any traffic police station or administrative service center in the area where the violation occurred or where the vehicle is registered. If the violation does not involve points, the fine can be paid directly at an ICBC self-service payment machine or online, including platforms like Alipay. If points are deducted, the owner must first confirm the violation and point deduction at a traffic police station before paying the fine. 2. The following are circumstances under which on-the-spot fine collection is permissible for motor vehicle driver violations: For non-local (defined as outside the municipality or prefecture/city, same below) transient drivers fined 20 yuan or less, the traffic officer may issue the penalty decision on the spot; in remote, hard-to-access areas and on highways, for non-local transient drivers fined more than 20 yuan, if the driver genuinely faces difficulty paying the fine at the violation location's collection agency and proactively requests it.

How Many Attempts Are Allowed for Subject One?

There is no limit on the number of attempts. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," candidates can take the Subject One exam twice on the same day. If the first attempt is unsuccessful, a second free retake is allowed. If the second attempt also fails, the Subject One exam for that day is terminated, and the candidate can only schedule another exam after ten days. Subject One, also known as the theoretical driving test or driver's theory exam, is part of the motor vehicle driving license assessment. The exam covers foundational driving theory, road safety laws and regulations, local regulations, and related knowledge. The test is computer-based and has a time limit of 45 minutes. A passing score for Subject One is 90 out of 100. The test consists of 100 questions, including single-choice and true/false questions, each worth 1 point. If a candidate answers 11 questions incorrectly, the system will automatically submit the test and end the exam. Subject One Exam Content: Driving license and motor vehicle management regulations; road traffic conditions and rules; traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized buses and trucks; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One Exam Notes: Candidates should dress appropriately—no slippers—and avoid bringing electronic devices or bags into the exam hall. Bring an ID card and queue to enter the waiting area. Observe the instructions and procedures displayed on the screen, and store personal belongings in lockers before entering the exam hall. Upon entering, candidates will be assigned a seat at the identity verification station. Once seated, begin the exam. Ensure the camera is aligned properly and follow exam discipline. If the first attempt fails, a same-day retake is allowed. If the retake also fails, the candidate must pay to reschedule. After the exam, queue to collect the score report and sign it—unsigned reports are invalid. There is no limit on the number of scheduling attempts for Subject One. Each subject allows one exam attempt, with one retake if failed. If the retake is also unsuccessful, the exam is terminated, and the candidate must reschedule. In contrast, Subject Two and Subject Three allow only five exam attempts. Scheduling for Subject Two and Subject Three must occur at least ten days later. If the Subject Three safety and civilized driving knowledge test is failed, the previously passed road driving skills test scores remain valid. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One covers traffic safety laws, regulations, and related knowledge; Subject Two is the field driving skills test; Subject Three includes two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, the official terminology (as per the Ministry of Public Security Order No. 123) does not include "Subject Four."

If you're halfway through when the light turns red, does it count as running a red light?

If the front wheels of the vehicle have just crossed the stop line when the light turns red, and the vehicle stops immediately without moving, it will not be considered as running a red light. Continuing to proceed in violation of the rules constitutes running a red light, which results in a 6-point deduction. If the vehicle completes crossing the line and continues to move until it is completely past the line before stopping, affecting the passage of other vehicles and pedestrians, it will be penalized as crossing the line and stopping, usually resulting in a 3-point deduction on the driver's license and a fine. Crossing the stop line is divided into two situations: the front wheels of the vehicle cross the stop line; the entire body of the vehicle crosses the stop line. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states: Motor vehicle signal lights and non-motor vehicle signal lights indicate: When the green light is on, vehicles are allowed to pass, but turning vehicles must not obstruct the passage of straight-going vehicles and pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. When the red light is on, right-turning vehicles may pass provided they do not obstruct the passage of other vehicles and pedestrians. At intersections where there are no non-motor vehicle signal lights or pedestrian crossing signal lights, non-motor vehicles and pedestrians should follow the indications of the motor vehicle signal lights. The new traffic regulations clearly stipulate that the following three conditions must be met for a vehicle to be considered as running a red light: The vehicle illegally crosses the stop line. The vehicle illegally enters the intersection. The vehicle illegally crosses the opposite stop line. Electronic police (electronic eyes) capture three complete video images to constitute evidence of a vehicle running a red light: an image of the vehicle at the moment of violation; an image for license plate recognition; and a panoramic image. There are three scenarios regarding whether a vehicle is running a red light while driving: If the front wheels of the vehicle cross the stop line or both the front and rear wheels cross the stop line but the rear of the vehicle has not yet crossed the stop line and the vehicle stops immediately, the traffic police will not penalize it as running a red light, but may penalize it for improper parking, resulting in a 3-point deduction. As long as the front wheels of the vehicle cross the stop line, regardless of whether the entire body of the vehicle has completely crossed the stop line, if the vehicle stops and then reverses back, being captured by electronic eyes with two complete moving images processed, it will be treated as running a red light, resulting in a 6-point deduction and a fine. The new traffic regulations stipulate: Driving a motor vehicle in violation of traffic signal lights will result in a 6-point deduction. However, not all cases will lead to a 6-point deduction. For example, violations such as making a left turn from a straight lane will still be penalized under the "Road Traffic Safety Law" as violating prohibitory signs, resulting in a 3-point deduction. Additionally, red light running recorded by cameras will only result in a fine, with no point deduction.
