Devices for capturing reverse driving are usually installed at key sections, such as the on and off ramps of highways. The capture system compares front and rear images (for example, one second before and one second after) to determine if a vehicle is reversing. Different devices may have different principles, but this is generally how it works. Additionally, there are manually controlled cameras for capturing such violations. Here are some precautions for driving on highways: 1. Safety Check: Before getting on the highway, check for any potential safety hazards. 2. Seat Belts: Always wear seat belts, including in the front and rear seats, and avoid placing loose items in the car. 3. Stay in One Lane: Avoid frequent lane changes on the highway, switching between the passing lane and the driving lane, and never make sudden, unannounced decelerations or stops in the driving lane. Do not drive side by side with other vehicles, stay in the passing lane for extended periods, or attempt to overtake from the emergency lane. Also, prepare for lane changes well in advance when exiting the highway to avoid missing the exit.

I understand that the principle of capturing highway reverse driving is actually achieved through advanced surveillance systems. The main components are cameras and sensing devices installed at specific locations on the highway, such as gantries or roadside poles. When a vehicle starts moving in the wrong direction or reversing, these cameras can capture image changes in real-time, while sensors detect abnormal vehicle movement directions via radar. The system automatically analyzes this data, and if it identifies a violation, it immediately photographs or records the license plate number and specific location, then uploads the information to the enforcement platform for processing. The entire process is fully automated, requiring no human intervention. This technology effectively reduces traffic accidents because, at high speeds, reversing can easily trigger chain-reaction collisions with severe consequences. Therefore, understanding this principle is important as it helps remind us to obey traffic rules. It’s best to pay extra attention to road signs in daily driving to avoid mistakenly entering a wrong-way section and causing trouble.

Why is the supplementary page of the driver's license not laminated?

The supplementary page of a C1 driver's license cannot be laminated. The driver's license consists of a main page and a supplementary page; these two parts serve different functions. The main page records the driver's information and the types of vehicles they are licensed to drive. If this information does not change, the main page remains sealed. However, if changes occur, the license must be reissued. Below is relevant information about the supplementary page of the driver's license: 1. Function of the supplementary page: The supplementary page allows the police to record the license's file number and related matters. The file number is typically a 12-digit code. The first two digits represent the province code where the license was issued, the third and fourth digits indicate the district or county code, and the remaining eight digits are sequentially assigned by the local vehicle management office. Each driver's license has a unique file number, which helps identify the issuing authority and track the driver's penalty points. 2. Replacing the supplementary page: The replacement process is straightforward. The driver needs to bring their ID card, driver's license, two one-inch color photos with a white background, and the replacement fee to the local vehicle management office to complete the procedure.

How Much Gasoline Should Be Added for 100ml Fuel Additive?

100ML of fuel additive requires 50-100L of gasoline. Below is a detailed introduction to fuel additives: Functions of Fuel Additives: The role of fuel additives is to address carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the optimal working condition of the engine, and compensate for certain deficiencies in gasoline properties. They also impart new beneficial characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Precautions When Adding Fuel Additives: Currently, the common fuel tank capacity for small family cars on the market is 35-45L, mid-size cars around 55-75L, and large or luxury cars around 75-100L. The standard specification for fuel additives is 60ML, which typically can be mixed with 30-60L of gasoline. Therefore, a common family car usually requires 1-2 bottles of fuel additive per tank of gas, with the exact amount to be added depending on the specific circumstances of the vehicle.

How Many Times Can 2 Liters of Windshield Washer Fluid Be Used?

A two-liter bottle of windshield washer fluid does not have an exact number of uses. Normally, it can last for one to two months, depending on the frequency of use. Below is an extended introduction about windshield washer fluid: The Function of Windshield Washer Fluid: Automotive windshield washer fluid is formulated with various surface-active agents and additives. These surface-active agents have functions such as wetting, penetrating, and solubilizing, which help in cleaning. Additionally, it can lower the freezing point of the liquid, dissolving snow and frost on the car's windshield. Moreover, after cleaning, it forms a protective layer on the glass surface, preventing the formation of mist droplets and ensuring the windshield remains clear and bright, providing a clear view. Choosing Windshield Washer Fluid: Different seasons and climates require different types of windshield washer fluid. The selection mainly depends on temperature. For example, in winter, the fluid needs to be antifreeze, as regular washer fluid can easily freeze in cold weather. In summer, especially in southern regions where there are more insects, it is advisable to use washer fluid that contains insect-repellent properties.

What Causes Frosting on the Low-Pressure Pipe of a Car's Air Conditioning System?

Frosting on the low-pressure pipe of a car's air conditioning system is caused by a malfunctioning expansion valve or a faulty evaporator temperature sensor. More details are as follows: 1. Malfunctioning expansion valve: Frosting on the low-pressure pipe is often due to a faulty expansion valve, which fails to detect the real-time temperature of the low-pressure pipe. When the temperature drops too low, the pipe will inevitably frost (the expansion valve's opening cannot be reduced). This issue typically cannot be repaired and requires replacing the expansion valve. 2. Faulty evaporator temperature sensor: The problem may also stem from a defective evaporator temperature sensor. This component is designed to monitor the surface temperature of the evaporator and relay the data to the automatic air conditioning control unit. When the temperature falls below 2°C, the air conditioning system shuts down to prevent frosting or icing. If the evaporator temperature sensor fails, it cannot detect the correct temperature data, leading to frosting on the low-pressure pipe. In this case, replacing the sensor is necessary.

What Causes Loud Interior Noise When the Car is Running?

There are several reasons for loud interior noise when a car is running, including engine noise, tire noise, wind noise, and chassis noise. Below are explanations for the causes of loud noise while driving: Engine Noise: Check if the engine oil pump, cooling system, or exhaust pipe is cracked, then adjust the valves and inspect the engine oil pressure. If everything appears normal but the noise persists, consider adding a soundproofing pad under the hood. Tire Noise: Adjust the tire pressure to a moderate level, as excessively high tire pressure can increase noise. Additionally, attaching a piece of felt to the mudguards can help reduce tire noise. Wind Noise: The faster the driving speed, the louder the wind noise becomes. Adding sealing strips to the door frames or incorporating soundproofing material inside the doors can effectively reduce the noise entering the car. Chassis Noise: The chassis may create friction with the air. Applying soundproofing pads and vibration damping sheets to the bottom of the trunk can help mitigate this noise.
