Related explanations are as follows: Introduction: Subject One, also known as the Subject One theory test or driver theory test, is part of the motor vehicle driver's license assessment. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the test is conducted on a computer, with 100 questions, a full score of 100, and a passing score of 90 or above. Additional Note: Subject One follows a "test once, retest once" policy, meaning if you fail the test on the spot, you can retake it once.

What is HUD Head-Up Display?

HUD Head-Up Display Introduction: HUD Head-Up Digital Display, also known as the Head-Up Display System, uses projection technology to map important information onto the holographic semi-mirror of the windshield, allowing drivers to see critical information without having to look down. Here is an introduction to the advantages of HUD Head-Up Digital Display: 1. Drivers can see information without lowering their heads, thereby avoiding distraction from the road ahead. 2. Drivers do not need to adjust their eyes between observing the distant road and nearby instruments, effectively preventing eye fatigue. In summary, the function of this display system is to improve vehicle safety. Of course, this system is costly and is still difficult to popularize in automobiles at present.

Do You Need to Change Car Antifreeze in Summer?

You need to change car antifreeze in summer. According to the requirements of the car maintenance manual, antifreeze should be used at all times, and water should not be used as a substitute for antifreeze. Therefore, antifreeze should also be replaced promptly in summer. Antifreeze replacement cycle: For vehicles that run for long periods, such as taxis, high-quality antifreeze generally needs to be replaced once a year. For vehicles with shorter running times, it can be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended matter, sediment, deterioration, or discoloration is found in the antifreeze, it should be replaced promptly, and the system should be cleaned. Antifreeze composition: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances.

What Causes Car Body Shaking?

Here are the reasons that cause car body shaking and the solutions: 1. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. Solution: Check the oil pressure and replace components if necessary. 2. Aging engine components: Car shaking can also be related to worn engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the cabin, causing shaking during idle. Solution: Replace the components. 3. Severe engine carbon buildup: Dirty throttle body or excessive carbon deposits on the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, leading to an overly lean air-fuel mixture during cold starts and making it difficult to start. Solution: Clean the fuel system and check if the idle control valve has carbon deposits that need cleaning.

How to Check the Production Date of Your Car?

Every car has a nameplate indicating the production date. Generally, there are two nameplates: one in the engine compartment and another on the side of the driver's door. The production date of the car is clearly marked on these nameplates. In addition, here are three other methods to check the production date of your car: 1. Check the VIN (Vehicle Identification Number) under the windshield: The 10th character of the VIN represents the production date, and each car has a unique VIN. 2. The vehicle identification code consists of 17 characters, and the 10th character from the left indicates the production time, allowing you to more accurately determine the car's age. 3. Look at the car's VIN code: Each VIN code represents a unique car and is often referred to as the vehicle identification number or chassis number. The VIN code is located under the front windshield, and its 10th character indicates the production date of the car.
