How to handle 12 demerit points on an A2 driver's license?

A2 driver's license with 12 demerit points requires visiting the vehicle management office to process a downgrade and cancel the highest driving qualification. Below is an introduction to the relevant content regarding accumulating 12 demerit points on a driver's license: 1. A driver's license with a total of 12 demerit points cannot be used for driving. 2. The traffic management department of the public security organ shall confiscate the motor vehicle driver's license. 3. The motor vehicle driver shall, within 15 days, go to the traffic management department of the public security organ at the place where the driver's license was issued or where the violation occurred to participate in a seven-day road traffic safety law course. Below is extended information about situations where a motor vehicle driver's violation results in 3 demerit points at one time: 1. Driving a passenger vehicle other than an operational passenger vehicle or school bus with passengers exceeding the approved number by less than 20%. 2. Driving a medium-sized or above passenger or cargo vehicle, or a dangerous goods transport vehicle on roads other than highways or urban expressways, or driving other motor vehicles at a speed exceeding the prescribed limit by less than 20%. 3. Driving a cargo vehicle with a load exceeding the approved weight by less than 30%. 4. Driving a motor vehicle on a highway below the prescribed minimum speed limit. 5. Driving a motor vehicle prohibited from entering a highway onto a highway.

Is the AC button in the car for cold air or hot air?

AC button is the cooling switch of the car air conditioning. When the AC button is pressed, the car air conditioning will cool, so AC is for cold air. The relevant introduction of car air conditioning cooling is as follows: 1. Introduction to the use of AC: After pressing the AC button, the compressor clutch will engage, and the engine will drive the compressor to run, so that the compressor can continuously compress the refrigerant and deliver it to the evaporator. The AC button is the switch for the cold air conditioning. When pressed, the compressor works while the cold/hot knob is adjusted to the cold zone, and the blower (1, 2, 3, 4) is turned on, at which time cold air is blown out. Hot air conditioning does not require pressing the AC button. 2. Introduction to the AUTO function: The AUTO gear is a unique function of the car's automatic air conditioning, which automatically selects cold or hot air based on the set interior temperature. However, the AC button does not need to be activated when cooling is not required, with the purpose of saving fuel by not letting the compressor work when cooling is not needed.

What are the key details to pay attention to in Subject 3?

The following are the details that need attention during the Subject 3 driving test: 1. Lighting assessment content. 2. Students need to master the requirements for lighting usage. 3. It is necessary to familiarize oneself with the Subject 3 road test route in advance. 4. Do not exceed the specified speed when driving, and ensure that parking is done correctly. Below is extended information about the Subject 3 test content: 1. Vehicle preparation, starting, and driving in a straight line. 2. Gear shifting operations, changing lanes, and parking by the side of the road. 3. Driving straight through intersections, turning left at intersections, and turning right at intersections. 4. Passing through pedestrian crossings, school zones, and bus stops. 5. Meeting vehicles, overtaking, making U-turns, and driving at night.

How Much Antifreeze Should Be Added?

Antifreeze is generally added in two stages, totaling 5 to 6 liters. The first stage is when the vehicle is stationary: add the antifreeze while gently squeezing the rubber hose until the fluid level reaches midway between the 'low' and 'high' marks. The second stage occurs after the vehicle has been driven for a distance. Observe whether the coolant level has dropped. If it has, wait for the engine to cool down after parking, then add more antifreeze. Below is some information about antifreeze: 1. Definition of Antifreeze: Automotive antifreeze, also known as antifreeze or non-freezing liquid, is technically called automotive antifreeze coolant. It is a coolant with antifreeze properties, designed to allow vehicles to operate in low winter temperatures. 2. Types of Antifreeze: There are many types of automotive antifreeze agents, including inorganic substances like calcium chloride (CaCl2), organic substances like methanol (CH3OH), ethanol (C2H5OH, commonly known as alcohol), ethylene glycol (C2H4(OH)2, commonly known as sweet alcohol), glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oils, and everyday substances like sugar and honey. These can serve as the base liquid for antifreeze. By adding an appropriate amount of pure soft water (water with little or no calcium or magnesium ions, such as distilled water, uncontaminated rainwater, or snowmelt, with a total hardness concentration between 0-30ppm), it becomes what is generally referred to as antifreeze.

What Causes Body Vibration at 120 km/h on the Highway?

There are two main reasons for steering wheel vibration when braking at 120 km/h on the highway. Below are the relevant explanations: 1. Uneven brake disc wear: When the brake discs are unevenly worn, steering wheel vibration may occur during high-speed braking. When braking at a certain speed, the left and right wheels on the same axle may experience uneven braking force, causing an alternating tight and loose braking effect. If this imbalance reaches a certain level, it can lead to unequal rolling speeds between the left and right wheels, resulting in side-to-side wheel oscillation, which is then transmitted to the steering wheel. 2. Drivetrain malfunction: Another possible cause of steering wheel vibration during high-speed braking is an issue with the vehicle's drivetrain. In such cases, it's advisable to check the tie rods and tie rod ends for rust or looseness.

What does maxa/c mean on the air conditioning?

Car air conditioning MAX A/C refers to the maximum cooling mode of the air conditioning system. The MAX A/C button is the switch to activate the maximum cooling mode. When this function is turned on, the cooling effect is enhanced for greater convenience and efficiency. Here are some related details: 1. A/C function introduction: A/C stands for air-conditioning, which can be understood as air control or air regulation. Its role in a car is essentially the switch for the air conditioning cooling system. When the A/C light is on, it indicates that the air conditioning compressor is activated, increasing engine load and fuel consumption. Pressing this button activates the compressor, allowing the blower to produce cold air. Once the A/C button is pressed, the electromagnetic clutch of the air conditioning compressor engages, causing the compressor to operate with the engine and enter the cooling state. 2. MAX A/C function introduction: After activating the maximum cooling mode, the fan speed automatically adjusts to the highest setting, significantly improving the cooling effect by increasing the cooling capacity. If you're concerned about whether using the MAX A/C button will increase fuel consumption due to the higher cooling capacity, it's recommended to stick with the standard A/C mode.
