Can a vehicle be inspected during annual inspection if there are traffic violations?

What documents are required to replace a vehicle registration certificate?

To replace a vehicle registration certificate, the required documents include the "Motor Vehicle License Plate and Certificate Application Form", the original and photocopy of the vehicle owner's identity proof, and the Motor Vehicle Inspection Record Form (processed on-site). The relevant details are as follows: 1. Applying for a replacement of the motor vehicle registration certificate: The vehicle owner should drive the vehicle to the vehicle management office. If the vehicle owner is a natural person applying for the replacement of the "Motor Vehicle Registration Certificate", they must apply in person and cannot authorize someone else to act on their behalf. If the vehicle owner is unable to apply in person due to reasons such as death, overseas travel, severe illness, disability, or force majeure, they can authorize an agent to apply for the replacement with relevant supporting documents. 2. The vehicle owner can authorize an agent to apply for various motor vehicle registrations and operations: except for applying for the replacement of the motor vehicle registration certificate. If the vehicle owner cannot apply for the replacement of the motor vehicle registration certificate due to death, overseas travel, severe illness, disability, or force majeure, they can authorize an agent to apply for the replacement on their behalf with relevant documents.

What Are the Parking Assistance Functions?

The most commonly used parking assistance systems are the reverse radar system or the reverse system using sonar sensors. Their function is to alert the driver to objects behind the vehicle when reversing. The relevant details are as follows: 1. Introduction to Reverse Radar: The reverse radar is a safety assistance device for parking or reversing a car. It informs the driver about surrounding obstacles through sound or more intuitive displays, eliminating the trouble caused by the driver's need to look around when parking, reversing, or starting the vehicle. It also helps the driver overcome blind spots and unclear vision, improving driving safety. 2. Working Principle of the PDC System: Typically, radar detectors are installed on the rear bumper or both front and rear bumpers of the car to detect obstacles in front and behind, helping the driver see obstacles ahead and behind or the distance from other cars when parking. Besides facilitating parking, this device can also protect the car body from scratches. The PDC uses ultrasonic sensors to detect the distance to the nearest obstacle and emits an alarm sound to warn the driver. The alarm sound control is usually divided into two stages. When the vehicle reaches a certain initial detection distance, the alarm starts with a high-frequency beep. When the vehicle moves closer to a certain distance, the alarm changes to a continuous beep to alert the driver.

Which gear should be used when driving uphill with a CVT transmission?

When driving uphill with a CVT transmission, shift to the M (Manual) or L (Low) gear to maintain higher torque output from the engine for climbing. Car gear operations: 1. D is the Drive gear, used for normal road driving; 2. R is the Reverse gear, which can only be engaged after the car has come to a complete stop; 3. P is the Parking gear, used when the car is stationary and should be engaged along with the handbrake; 4. L is the Low gear, which provides greater power output; 5. N is the Neutral gear, used when the car is temporarily stopped; 6. W is the Winter gear, suitable for driving on slippery or snowy surfaces; 7. E is the Economy gear; 8. S is the Sport mode driving gear. Precautions for gear shifting: 1. Ensure the gear is in N or P before starting the engine, and remember to press the brake pedal when starting; 2. Gear shifting should be timely, accurate, decisive, and quick, avoiding hesitation; 3. Upshift after accelerating and downshift after decelerating; 4. Use D gear for driving on flat and straight roads; 5. No need to press the shift button when switching between N, D, and 3rd gear.

Why are the steering wheels on the right side of cars in Hong Kong?

The steering wheels in Hong Kong are on the right side because, before its return to China, Hong Kong was influenced by the UK, where traffic rules dictate driving on the left side. Even after the handover, Hong Kong has continued to follow the left-hand driving system. Due to historical reasons, Hong Kong follows left-hand traffic rules, while mainland China follows right-hand traffic rules. Therefore, after Hong Kong's return in 1997, the 'one country, two systems' approach was also applied to road traffic regulations. When mainland vehicles enter Hong Kong, they must follow Hong Kong's left-hand driving rules. Conversely, Hong Kong vehicles entering the mainland must also adapt to local customs. This arrangement has led to many inconveniences. Although clear boundary signs are erected at the border between Hong Kong and the mainland, the busy traffic makes it difficult for incoming vehicles to switch driving sides immediately upon crossing the border. To address this issue, a special bridge was constructed at the Shenzhen-Hong Kong border. Incoming vehicles only need to follow their original driving rules, and through the bridge's clever design, right-hand drive vehicles naturally switch to left-hand drive in Hong Kong, and vice versa.

Why does the Audi A4 air conditioning suddenly stop cooling?

Here are the reasons and solutions for the Audi A4 air conditioning not cooling: 1. Too much or too little refrigerant can cause the car air conditioning to stop cooling. Excessive refrigerant is usually caused by overfilling during maintenance, as the proportion of refrigerant in the air conditioning system must meet certain requirements. If the proportion is too high, it can affect heat dissipation, meaning more heat dissipation results in greater cooling capacity; conversely, less heat dissipation results in lower cooling capacity. If there is insufficient refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease, and the heat absorbed during evaporation in the evaporator will consequently decrease, leading to reduced cooling capacity. Solution: If there is too much refrigerant in the car air conditioning, some can be slowly released from the maintenance port on the low-pressure side of the system. If there is insufficient refrigerant, it should be added. However, when adding refrigerant, note that if adding from the low-pressure side, the refrigerant bottle must not be placed upside down, and if adding from the high-pressure side, the engine must not be started. 2. Loose compressor drive belt. If the car air conditioning compressor drive belt is loose, the compressor may slip during operation, reducing transmission efficiency and thus decreasing the cooling effect. Solution: Check if the drive belt is broken or loose, if there is noise inside the compressor, and if the compressor clutch is slipping.

Where is the standard position for a shark fin antenna?

The shark fin antenna is installed on the roof of the car, above the rear windshield. Utilizing electronic properties, the shark fin antenna directs static electricity to its tip for release. Regardless of its installation position on the car, it effectively reduces static electricity. The specific functions of the shark fin antenna are as follows: After installing a shark fin antenna, airflow is split by the fin before forming tail vortices, thereby reducing driving resistance. Particularly at speeds above 100km/h, the "shark fin" antenna significantly aids in lowering fuel consumption. Wind tunnel experiments have shown that the "shark fin" antenna can reduce high-speed fuel consumption by 3%, a remarkably encouraging figure. Essentially, the shark fin serves as a car antenna, intercepting high-frequency radio waves from transmission towers and delivering them to the car's radio, mobile phone, or navigation receiver for demodulation. Given cars' high sealing requirements, internal communication signals can weaken. To enhance signal strength, antennas are designed into vehicles. The "shark fin" antenna's primary advantage over traditional antennas is its superior signal enhancement. Its built-in signal receiver offers strong anti-interference capabilities and minimal radio wave disruption, ensuring both improved signal strength and stability. Additionally, it eliminates the aerodynamic noise associated with rod antennas, providing a quieter ride. Moreover, during dry seasons, vehicles are prone to static electricity, which can damage onboard circuits. The "shark fin" antenna effectively addresses this issue by acting as a static discharger, safely releasing accumulated static to protect both vehicle electronics and passenger safety.
