Why Do License Plates Fall Off When Wading Through Water?

When a vehicle drives on a waterlogged road, water hits the bumper and surges upward upon encountering resistance, eventually squeezing into the gap between the license plate and the bumper. This means the license plate is subjected to an outward pushing force. As the vehicle moves forward, the license plate also faces resistance from the water coming from the front. Under the pushing force, the license plate is pried outward, while under the resistance, it is pressed back toward the vehicle body. This repeated action causes a license plate secured with only two screws to sway back and forth and eventually fall off. Additional Information: 1. Number of License Plate Fasteners: According to the "Safety Technical Conditions for Motor Vehicle Operation," each license plate of a newly manufactured motor vehicle should have four installation holes. Metal license plates should be equipped with fasteners that meet the GA804 requirements, unless vehicle conditions prevent their installation. Special fasteners for motor vehicle license plates should be used, ensuring they are complete and securely installed. 2. Replacing a License Plate: Currently, the Municipal Vehicle Management Office and its branches have adopted a "one-window" service model. At any service window of the Municipal Vehicle Management Office and its branches, vehicle owners can complete the license plate replacement process by presenting their ID card. They can choose to pick up the new license plate in person or have it mailed to their home.

What is the speed limit on highways in kilometers per hour?

Generally, the economical speed for economy cars is 60-80 kilometers per hour, while mid-to-high-end cars have an economical speed of 80-90 kilometers per hour. On regular roads, cars typically travel at around 60 kilometers per hour, whereas on highways, the speed is approximately 100 kilometers per hour, with a legal maximum of 120 kilometers per hour. Additional information: Upon entering the highway, vehicles should accelerate to at least 60 kilometers per hour as soon as possible. Driving too slowly can lead to rear-end collisions. Key points: 1. Speed limits: Highways must indicate lane speed limits, with a maximum speed not exceeding 120 kilometers per hour and a minimum speed not below 60 kilometers per hour. 2. Vehicle type requirements: On highways, the maximum speed for small passenger vehicles must not exceed 120 kilometers per hour, while other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. 3. Lane requirements: For two lanes in the same direction, the minimum speed in the left lane is 100 kilometers per hour. For three or more lanes in the same direction, the minimum speed in the far-left lane is 110 kilometers per hour, and the middle lane's minimum speed is 90 kilometers per hour. If the speed limit indicated by road signs differs from these lane speed regulations, drivers must adhere to the speed limit specified by the road signs.

What are the reasons why the Wuling Hongguang Mini cannot start?

There are many reasons that may cause a vehicle to fail to start, and it is recommended to troubleshoot the problem in a timely manner. Below is a detailed analysis of the specific reasons for a car's failure to start: 1. Battery depletion: When the voltage during startup is lower than the minimum operating voltage required by the computer, the engine computer does not work, preventing the car from starting. In this case, the battery should be charged or replaced. 2. Spark plug failure to ignite: Spark plugs themselves are prone to damage, and issues like short circuits in high-voltage lines can cause spark plugs to fail to ignite. Additionally, poor-quality spark plugs are another reason for failure to start normally. In such cases, it is recommended to replace the spark plugs. 3. Starting circuit malfunction: During startup, there is only a slight 'click' sound with no further response, which is caused by a stuck starting relay. In this situation, pressing the tail of the electromagnet to force it forward can connect the starting circuit, thereby enabling the engine to start. 4. Use of inferior engine oil: During cold starts, factors such as cylinder pressure, rotation speed, and temperature can make it difficult for inferior engine oil to ignite, leading to failure to start. It is recommended to use the engine oil recommended by the manufacturer or a higher-quality full synthetic oil.

How much over the speed limit is driving at 140 km/h?

Depending on the speed limit of the highway, driving at 140 km/h results in different percentages of speeding, as detailed below: 1. If the highway speed limit is 120 km/h, driving at 140 km/h is 17% over the limit. Calculation: (140-120) ÷120x100%=17%. 2. If the highway speed limit is 110 km/h, driving at 140 km/h is 27% over the limit. Calculation: (140-110) ÷110x100%=27%. 3. If the highway speed limit is 100 km/h, driving at 140 km/h is 40% over the limit. Calculation: (140-100) ÷100x100%=40%. 4. If the highway speed limit is 90 km/h, driving at 140 km/h is 55% over the limit. Calculation: (140-90) ÷90x100%=55%. 5. If the highway speed limit is 80 km/h, driving at 140 km/h is 75% over the limit. Calculation: (140-80) ÷80x100%=75%. 6. If the highway speed limit is 60 km/h, driving at 140 km/h is 133% over the limit. Calculation: (140-60) ÷60x100%=133%.

What does Emergency Lane Keeping mean?

Emergency Lane Keeping System intervenes more actively in the driving path only when an emergency situation is detected. Introduction to Lane Keeping Assist System: Lane Keeping, fully known as Lane Keeping Assist System, is a type of intelligent driving assistance system. When the vehicle deviates from the recognized lane markings, the steering wheel will vibrate, and the vehicle will alert the driver with a "beep" sound to pay attention to safe driving. Function of Lane Keeping Assist System: The Lane Keeping Assist System helps correct the driving path when the vehicle gradually deviates from the lane. Typically, the system will issue a warning to the driver to correct the driving path; however, these systems will also slightly steer the vehicle to prevent it from continuing to deviate from the lane.

What causes the abnormal noise when stepping on the accelerator in a Sylphy?

The reasons for abnormal noise when stepping on the accelerator in a Sylphy may be: This phenomenon is likely caused by the sound from the valves, or it could be due to insufficient engine oil leading to lack of lubrication in the valves. During cold starts, the engine noise is generally slightly louder than when the engine is warm. The reasons for abnormal noise when stepping on the brake in an automatic transmission vehicle are as follows: 1. Normal activation of ABS: The working process of ABS is actually a cycle of locking and releasing, keeping the vehicle in a state of critical lock rolling. When you step on the brake hard and trigger the ABS, it will produce a clunking sound, which is normal. In this case, simply press the brake pedal firmly to the bottom. 2. The gear makes a "clunk" sound when stepping on the brake in an automatic transmission vehicle: If you hear a "clunk" sound between the transmission and the gear lever when stepping on the brake pedal, the main reason for this noise may be the electronic linkage between the brake system and the automatic transmission. When you step on the brake, the transmission solenoid valve opens and produces a "clunk" sound. At this time, you need to press the gear lock button to shift gears, which serves as a safety reminder.
