Can I still drive if my car has 12 points deducted?

The motor vehicle can still operate normally. The driving license has no points left to deduct. Traffic violation points are assigned to the driver rather than the vehicle. If a driver accumulates 12 points within a scoring cycle due to driving that vehicle, the traffic police department should confiscate their driver's license. During the period when the license is confiscated, the driver is not allowed to drive any motor vehicle. Below is extended information about driver's licenses: 1. Handling method: The driver must report to the traffic management department of the public security organ at the place where the motor vehicle driver's license was issued or where the violation occurred within fifteen days to participate in a seven-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office should conduct an examination on road traffic safety laws, regulations, and related knowledge within twenty days. If the examination is passed, the points will be cleared, and the motor vehicle driver's license will be returned; if the examination is not passed, the driver must continue to study and take the exam. Drivers who refuse to participate in the study or take the exam will have their motor vehicle driver's license suspended by the traffic management department of the public security organ. 2. Motor vehicle handling method: The vehicle will not be prohibited from operating on the road just because its driver has accumulated 12 points. As long as there is a qualified driver, the motor vehicle can still be driven normally on the road.

What is the difference between car coating and crystal coating?

Car crystal coating and regular coating differ in brightness, working principles, and scratch resistance. The specific differences are as follows: Brightness difference: Crystal coating produces a diamond-like 3D iridescent effect, whereas regular coating only creates a crystal-clear mirror finish. Principle difference: Regular coating works by penetrating protective agents into the car paint to enhance its protection. Crystal coating, on the other hand, forms a protective layer of certain thickness on the paint surface, creating a solid shield. Scratch resistance difference: The thickness of the film layer formed by crystal coating is 2-3 times that of regular coating, resulting in significantly better scratch resistance.

Is It Normal for the Car Fan to Keep Running After the Engine Is Turned Off?

This is a normal phenomenon. If the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature for the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation automatically. The higher the engine temperature, the longer the fan will run after parking. When the engine coolant temperature drops below the soaking temperature, the fan will shut off to protect the engine and extend its service life. Below are common faults related to the car's cooling fan: 1. Whether the coolant temperature has reached the required level: Most car radiator fans operate based on electronic temperature control. Therefore, the fan will only start running normally when the coolant temperature inside the car reaches the required level. If the temperature is too low, the radiator fan will not operate. Thus, if your car's radiator fan fails to turn on, the first thing to check is whether the coolant temperature has met the requirement. 2. Relay malfunction: If the coolant temperature is appropriate but the car's radiator fan still does not work, the issue might lie with the fan's relay. A faulty relay can prevent the radiator fan from operating. 3. Issues with the temperature control switch: If neither of the above issues is present, then the temperature control switch should be inspected. Sometimes, faults in this component can also affect the operation of the car's radiator fan, so it is important to check this as well.

Can a broken clock spring causing the horn not to work be repaired?

A broken clock spring causing the horn not to work can be repaired. The clock spring functions similarly to an electrical wire. It ensures that power can still be transmitted even when the steering wheel is rotating. Since the car horn is an electric device that relies on the driver pressing the steering wheel to send an electrical signal, if the clock spring is damaged, the horn will not sound. Additionally, the functional buttons on the steering wheel and the airbag will not operate properly, significantly impacting daily use. Therefore, when the clock spring is damaged, it should be replaced promptly. The clock spring is a component of the car's airbag system, also known as a spiral cable. It is installed below the steering wheel and serves as a crucial part connecting the electrical components on the steering wheel to those on the steering column. Because the main airbag must rotate with the steering wheel, the clock spring needs to unwind or wind appropriately as the steering wheel turns. However, there is a limit to this movement—it must ensure that the wiring harness is not pulled apart when the steering wheel is turned to its extreme left or right positions. The clock spring is the wiring harness that ensures the airbag can deploy normally in an emergency. Since the main airbag rotates with the steering wheel, the connecting wiring harness must have some slack to prevent it from being pulled apart when the steering wheel is turned to one extreme position. This is particularly important during installation, and care should be taken to ensure it remains in the middle position as much as possible.

What are the symptoms of a faulty car sensor?

The symptoms of a faulty speed sensor are as follows: 1. Unstable engine idle speed, momentary stalling or engine shutdown when starting the vehicle or decelerating to a stop; 2. Decreased engine acceleration performance, deviation in the speed display on the dashboard, and illumination of the engine fault light; 3. If the speed sensor is damaged, it is necessary to promptly inspect and repair it at a repair shop. The function of automotive sensors is to convert various operational conditions of the vehicle, such as speed, temperature of various media, and engine operating conditions, into electrical signals that are transmitted to the computer, ensuring the engine operates in its optimal state.

What is the reason for frequent gear collision during gear shifting?

When shifting gears, if the gear cannot be engaged smoothly and there is often a gear collision sound, the reason is incomplete clutch disengagement. The following is a related introduction about shifting faults: The reasons for incomplete clutch disengagement: Excessive free travel of the clutch pedal; bending or deformation of the release lever, loose support, or detachment of the support pin, making it difficult to adjust the height of the inner end of the release lever; fatigue, insufficient height, or breakage of individual release springs; warping of the driven plate steel sheet, cracking of the friction plate, or loose rivets; oil leakage, air presence, or insufficient oil in the clutch hydraulic control mechanism; wear or damage to the engine support, causing misalignment between the engine crankshaft and the transmission input shaft. For fault diagnosis and elimination, check the free travel of the car's clutch pedal, and adjust it if the free travel is too large; for the hydraulic control mechanism, check whether the fluid reservoir has insufficient oil or if there is air in the pipeline and perform necessary elimination; check the height of the inner end of the release lever, and adjust it if the release lever is too low or not on the same plane. Fault diagnosis and elimination: First, determine whether the clutch can disengage or if the disengagement is complete. After confirming that the clutch is working normally, start the engine and perform gear shifting tests during car starting and road testing: shift sequentially from low gear to high gear, and then from high gear to low gear. If a certain gear cannot be engaged or is barely engaged and then difficult to disengage, or if there is a gear collision sound during the shifting process, it indicates difficulty in shifting that gear. When the transmission has difficulty shifting gears, the fault can be diagnosed and eliminated using the following method.
