The QR code for motor vehicles is located in the lower left corner of the front windshield or in the vehicle's manual. In some cities, it can also be found on the license plate. The QR code contains information such as the issuing authority, unique serial number, license plate number, as well as technical parameters of the vehicle and owner details. The QR code can be scanned using the Traffic Management 12123 app. The QR code on the vehicle registration certificate requires special scanning equipment used by traffic police departments, as ordinary mobile phones cannot recognize the QR code on the license plate to prevent personal information leakage. For ordinary motor vehicles, the QR code is usually found on the accompanying documents, such as the configuration sheet, which typically includes the vehicle's specific configurations. There will be a QR code displaying detailed information about your vehicle. The specific application of QR codes in vehicle management involves the management of vehicle information, safety, inspection, and approval. As a means of transportation, vehicles and their drivers are constantly in dynamic motion across time and space. The functions of the vehicle QR code include: Converting and storing vehicle-related information in the QR code; Automatically recording the vehicle's annual inspection documents; Enabling traffic police to record traffic violation penalties by scanning the QR code; Querying the vehicle's annual inspection status via the QR code; Establishing a vehicle monitoring network to ensure effective, real-time, and automated vehicle management. As a new automatic identification and information carrier technology, QR codes have been widely used in fields such as national defense, customs, taxation, public security, and transportation for automatic information carrying, transmission, and anti-counterfeiting purposes.

I've been into cars for twenty years, and the QR code for motor vehicles is most commonly found on the vehicle license, especially on the information page of the cover. A quick scan instantly reveals details like the vehicle model, registration date, and VIN. This design is incredibly convenient—no need to sift through piles of documents. In my hometown, after the city roads implemented intelligent management, a small QR code label was also placed on the top left corner of the windshield, making it easy for traffic police to quickly verify during duty. I remember once during a road trip, I had a friend scan my vehicle license, and it immediately identified whether it was legitimate, avoiding potential hassles later. If the QR code is lost—for example, due to document wear—you need to rush to the DMV for a replacement to avoid delays in registration or insurance claims. In the digital age, using a phone to scan QR codes can handle all vehicle-related matters safely and efficiently.

What does simulated 10-speed mean?

Simulated 10-speed refers to a transmission that has 10 forward gears during operation, typically found in CVT (Continuously Variable Transmission) systems. Here's a detailed introduction to the advantages and disadvantages of CVT transmissions: 1. Advantages: CVT transmissions are compact, structurally simple, easy to maintain, and provide smooth operation. They are primarily used in Japanese, Korean, and some domestic vehicles. CVT transmissions allow the engine to consistently operate within an optimal RPM range, making vehicles equipped with them generally more fuel-efficient. 2. Disadvantages: The drawbacks of CVT transmissions include lower torque capacity and susceptibility to slippage. As a result, CVT transmissions are usually paired with small-displacement engines. High-displacement engines with greater torque output typically require AT (Automatic Transmission) systems instead.

What Insurance Must Be Purchased for a New Car?

New cars must have compulsory traffic insurance. Below is a detailed introduction to car insurance: 1. Compulsory Traffic Insurance: Compulsory traffic insurance is a legal requirement that every car owner must purchase. It provides the most basic insurance claims when a traffic accident occurs. In the event of an accident, compulsory traffic insurance can help the car owner cover the economic compensation that would otherwise be difficult to pay. The compensation amount for compulsory traffic insurance is determined based on the car owner's proportion of responsibility in the accident and whether it caused personal injury or death. 2. Vehicle Damage Insurance: Vehicle damage insurance refers to situations where the insured or an authorized driver causes an insured accident while driving, resulting in damage to the insured vehicle. The insurance company will provide compensation within reasonable limits. The premium for vehicle damage insurance is closely related to the purchase price of the car and the number of seats. 3. Third-Party Liability Insurance: Third-party liability insurance covers situations where an accident causes personal injury, death, or direct property damage to a third party other than the driver and passengers of the insured vehicle. The insurance company will provide compensation according to regulations.

What items are required for Subject 4?

For the Subject 4 exam, you only need to bring your ID card; no other items are required. The Subject 4 exam consists of 50 questions, primarily presented in the form of case studies, images, and animations. The total score is 100, with a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and an additional safety and civics knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Since this test is conducted after Subject 3, it is colloquially called the Subject 4 exam. Officially, there is no such term as Subject 4. If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no additional fees are required for the retake. There are no restrictions on the number of retakes, but the validity period of the driving skill test permit is three years. If the applicant does not complete the exam within this period, the scores of the previously passed subjects will become invalid.

What is an Automotive Air Conditioning Pressure Gauge?

An automotive air conditioning pressure gauge consists of two pressure gauges (low-pressure gauge and high-pressure gauge), two manual valves (low-pressure manual valve and high-pressure manual valve), and three hoses (one connected to the low-pressure gauge service valve, one connected to the high-pressure gauge service valve, and one connected to the refrigerant tank or vacuum pump interface, which can also recover refrigerant). Below is information about automotive air conditioning pressure gauges: 1. Reading the Air Conditioning Gauge: The air conditioning gauge typically has two dials, one blue and one red. The blue dial is the low-pressure gauge, and the red one is the high-pressure gauge. Under normal operating conditions of the air conditioning system, the low pressure ranges between 1.0–2.5 bar, and the high pressure ranges between 15–18 bar, with slight variations possible. When the system is idling, the high pressure may be slightly lower, and as the engine speed increases, the high pressure may rise slightly while the low pressure may drop slightly, though the changes are not significant. 2. Factors Affecting Air Conditioning System Pressure: The pressure in an automotive air conditioning system is influenced by various external conditions, such as ambient temperature, engine speed, condenser cooling conditions, etc. Therefore, the standard for measuring automotive air conditioning system pressure is based on specific environmental temperatures, compressor speeds within a certain range, and condenser cooling under certain conditions, rather than being a fixed standard.
