Can Traffic Police Check After Passing Subject 4?

After passing Subject 4, it usually takes one or two hours for the system to show that you have passed the exam. Once Subject 4 is completed, your driver's license information will be automatically filed on the Traffic Police 12123 platform. If you are unsure, you can check the exam appointment section. If you click in and see a message stating "You have not registered for the driver's exam," it means you have passed all the tests and only need to wait for your driver's license to be mailed. Below are additional notes on what to pay attention to during the period before receiving your physical license: 1. Even if the Traffic Police 12123 shows your driver's license has been filed, you cannot drive on the road until you receive the physical license. According to traffic regulations, driving a motor vehicle requires carrying a driver's license. If you are caught without it, you will be penalized with one point per violation, and in severe cases, your vehicle may be impounded. 2. During the probationary period, your vehicle must display a "Probationary Driver" sign at the rear. If you need to drive on the highway during this period, you must be accompanied by an experienced driver with over three years of driving experience in the passenger seat. Driving alone on the highway during the probationary period is prohibited by law.

Why can't tubeless tires be repaired?

Due to the lack of inner tube support inside tubeless tires, patches are not very secure and may fall off. Therefore, tubeless tires are not suitable for repair. Here is some relevant information: 1. Tubeless tires: Tubeless tires are pneumatic tires without inner tubes, also known as "low-pressure tires" or "pneumatic tires." They have high elasticity and wear resistance, as well as good adhesion and heat dissipation performance. Tubeless tires are increasingly widely used in bicycles, motorcycles, cars, buses, and trucks. 2. Structure: Tubeless tires are divided into three parts: the carcass, the cord ply, and the tread. The carcass is relatively soft, the tread is more rigid, and the middle cord ply serves to strengthen the carcass and maintain its shape, often reinforced with metal wires to improve the tire's elastic performance.

Is the 909018 3.00-18 tire universal?

Not universal. The 3.00-18 tire can be interchanged with flat tires 110/90-18 or 120/90-18. Here is relevant information: 1. Automobile tire structure: According to different carcass structures, automobile tires can be divided into pneumatic tires and solid tires. The vast majority of modern vehicles use pneumatic tires. Based on internal air pressure levels, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Low-pressure tires are commonly used across various vehicle types. 2. Usage classification: Tires are classified by purpose, including truck tires, passenger vehicle tires, and mining tires among others. In addition to specification markings on the sidewall, truck tires must also indicate ply rating.

Is Tire Repair Glue Safe for Punctures?

Hot vulcanizing patch is highly reliable. It can completely ensure the safety of the tire. However, the hole caused by the nail should not be too large; holes smaller than 2 millimeters can be securely repaired. Below is an introduction about tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling on the ground. 2. History: In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title "Improvement in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. 3. Function: Tires are often used under complex and harsh conditions. During driving, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing, traction, and cushioning performance. At the same time, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, indicating the significant demand for rubber in tire manufacturing.

What is the difference between L2 and L3 autonomous driving?

Autonomous driving L2 is semi-autonomous driving, while L3 can achieve partial autonomous driving operations in specific environments. Here are the detailed introductions: 1. L2: L2 achieves semi-autonomous driving, allowing the vehicle to perform multiple functions, and the driver can take short breaks with their hands, but they still need to be ready to take over the driving task at any time. The functions included in L2 level are: full-speed adaptive cruise control, automatic parking, active lane keeping, speed limit recognition, automatic lane changing, etc. 2. L3: L3 enables the vehicle to perform partial autonomous driving operations in specific environments. It can judge whether to continue autonomous driving or return to manual operation by the driver based on road conditions, which can be considered as autonomous driving. The vehicle can almost independently complete all driving operations.

Do I Need to Press the Clutch and Brake When Starting the Engine in Subject Two?

For automatic transmission vehicles, you only need to press the brake to start. For manual transmission vehicles, the clutch must be fully pressed when starting. On flat roads or downhill starts, there is no need to press the brake. However, for uphill starts, you need to press the brake, though you can also use the handbrake instead of the footbrake. The clutch must be pressed; otherwise, the vehicle will stall. There are four main subjects in the driving test. Here are the details: 1. Subject One: Road passage, traffic signals, handling of traffic safety violations and accidents, regulations on the application and use of motor vehicle driving licenses, motor vehicle registration, and road traffic safety laws and regulations. 2. Subject Two: Reversing into a garage, stopping and starting on a slope, parallel parking, curve driving, and right-angle turns. 3. Subject Three: Road driving skills. Preparation before driving, starting, changing lanes, left turns at intersections, right turns at intersections, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and night driving. 4. Subject Four: Safe and civilized driving knowledge (theory).
