What is the maximum number of points that can be deducted from a driving license?

National regulations stipulate that a maximum of 12 points can be deducted from a driving license, with a yearly reset. Here is the relevant information: Points Deduction: If less than 12 points are deducted within a year, the points will be reset to zero on the date of license issuance. If 12 points are already deducted within a year, the driver must undergo training and pass an examination before the points can be reset to zero. Definition: The full name of a driving license is a motor vehicle driving license, also known as a "driver's license," which is a legally required certification for motor vehicle drivers. Main Classifications: The National Ministry of Public Security has further subdivided the previous three types of driving permits (A, B, and C) into seven types, while canceling the Q permit.

What Causes the Vehicle's Engine Malfunction Light to Stay On?

There are primarily 7 reasons for the engine malfunction light to illuminate: Sensor failure: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, leading to the illumination of the engine malfunction light. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear, resulting in the malfunction light turning on. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockages can all cause poor combustion of the engine's air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine malfunction light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, high oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe. Intake issues: If the vehicle's intake system has problems, it may lead to engine pipeline blockages, and in severe cases, the engine malfunction light will illuminate. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system failures can also cause the engine malfunction light to illuminate. Common causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft and bearing failures, with the catalytic converter being the most frequent culprit. The use of leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the catalytic converter, and fuel supply system failures can all easily lead to catalytic converter problems. Anti-theft system failure: If the vehicle's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine malfunction light will illuminate. If the engine malfunction light is on, follow these steps: First, check if the engine is running normally, and look for issues such as shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will perform a self-check after powering on. Wait for 5-10 seconds and observe if the malfunction light on the dashboard turns off. If the malfunction light remains on, visit a service station as soon as possible to identify the cause. The service station can use a portable diagnostic tool to read the fault codes, obtain fault information, and perform targeted repairs.

Why does the car shake violently when starting in first gear with half-clutch and no throttle?

The shaking of the car when starting in first gear with half-clutch may be caused by the following reasons: Reason 1: The clutch pressure plate is unevenly worn, resulting in insufficient power. Reason 2: Incomplete fuel combustion, excessive engine carbon deposits, or insufficient engine power itself. Reason 3: The engine and transmission are not properly aligned. Reason 4: The connection between the transmission and the chassis is loose. To determine the exact cause, each of these conditions should be checked one by one. It is recommended to go to a 4S shop for repair. Tips: Familiarize yourself with the clutch pedal operation and develop good habits—press it all the way down when engaging and release it slowly. Always use first gear when starting and pay attention to the coordination between the throttle and clutch.

Can you turn right at a Y-shaped intersection with a red light?

At a Y-shaped intersection, you can turn right when the light is red if there is a clear right-turn arrow signal, and you must obey the traffic light. If there is no red light prohibiting right turns at the intersection, you can turn right. Most traffic lights do not have arrow indicators, while some have left-turn arrow signals. At such intersections, you can still turn right when the light is red. At certain special intersections, right turns must also comply with the traffic light, and these intersections usually have signs to alert drivers. When driving on general urban roads, as long as you do not speed, run red lights, smoke while driving, make phone calls, and fasten your seatbelt, you will not commit any traffic violations. Laws and Regulations: According to the "Road Traffic Safety Law," the regulations on traffic lights are as follows: Article 25, Paragraph 2 states that traffic signals include traffic lights, traffic signs, traffic markings, and the directions of traffic police. Article 26 states that traffic lights consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. Article 38 states that vehicles and pedestrians shall pass in accordance with traffic signals; when directed by traffic police on-site, they shall follow the directions of the traffic police; on roads without traffic signals, they shall pass under the principles of safety and smooth traffic. Article 62 states that pedestrians crossing intersections or roads shall use crosswalks or pedestrian facilities; when crossing signalized crosswalks, they shall follow the traffic light signals; when crossing intersections without traffic signals or crosswalks, or crossing roads without pedestrian facilities, they shall cross only after confirming safety. Article 89 states that pedestrians, passengers, or non-motor vehicle drivers who violate road traffic safety laws or regulations regarding road passage shall be given a warning or fined between 5 and 50 yuan; non-motor vehicle drivers who refuse to accept the fine may have their vehicles impounded. Driving a motor vehicle in violation of traffic light signals results in a 6-point penalty. Right-Turn Precautions: Observe oncoming straight-moving vehicles: When turning right, check both the right and left sides for oncoming traffic. Observe opposing left-turning vehicles: In addition to watching for straight-moving vehicles, also check for opposing left-turning vehicles. When turning right, yield to vehicles on the left, whether they are turning left or going straight. Watch for pedestrians: When turning right, besides crosswalks before the intersection, there may also be crosswalks at the corner. Always check for pedestrians on the crosswalks.

What is the maximum speed for first gear?

First gear should not exceed 5 km/h. Below are detailed explanations about car gears: Speed aspect: Vehicle speed refers to the distance a car travels per unit of time. The corresponding speed for first gear is 0-5 km/h. Second gear corresponds to 5-20 km/h, third gear to 20-40 km/h, fourth gear to 40-60 km/h, and fifth gear to 60-100 km/h. Gear shifting timing: Vehicle speed can also generally refer to motor vehicle speed. For most cars, the optimal gear shifting occurs when the engine reaches 2000 r/min and should not exceed 2500 r/min. For high-displacement, high-power engines, shifting can be done around 3000 r/min.

Will the Engine Stall When Braking?

First gear semi-clutch braking will not cause the engine to stall. When the clutch is in the semi-engaged state, the friction between the pressure plate and the friction disc is less than that in the fully engaged state. Below is the relevant introduction: Because the semi-engaged clutch means the clutch is between disengagement and engagement, and the transmission system is between connection and disconnection, it can provide a flexible power output, which is often used in complex road conditions, starting, turning, and short-distance following. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the gearbox, thereby cutting off or transmitting the power input from the engine to the transmission. The clutch is a common component in mechanical transmission, allowing the transmission system to be separated or engaged at any time. The basic requirements for the clutch are smooth engagement, quick and thorough disengagement, easy adjustment and repair, small external dimensions, light weight, good wear resistance, and sufficient heat dissipation capacity.
