Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The following are specific details: 1. When visibility is less than 50 meters: Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 20 kilometers per hour, and you should exit the highway from the nearest exit as soon as possible. 2. When visibility is less than 100 meters: Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 40 kilometers per hour, and you should maintain a distance of more than 50 meters from the vehicle in front in the same lane. 3. When visibility is less than 200 meters: Turn on the fog lights, low beam lights, clearance lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and you should maintain a distance of more than 100 meters from the vehicle in front in the same lane. 4. Notes: If fog lights are not installed, turn on the small lights and running lights of the vehicle. If the car is stationary, turning on the hazard warning flashers is acceptable, but they should not be used while driving.

Can I not replace the driving license if it is full of stamps?

If the driving license is full of stamps, it cannot be left unreplaced. You need to bring the owner's ID card, the motor vehicle driving license, and the motor vehicle registration certificate to the local vehicle management office or public security traffic management department for replacement. The motor vehicle driving license is subject to annual or biennial review, and the review time is determined based on the type and age of the vehicle. The purpose is to better control the use of the driving license and to promptly determine whether the holder still meets the conditions for the driving license. The process for replacing an expired driving license: 1. The replacement must be done within three months (90 days) before expiration by participating in the motor vehicle inspection; 2. For vehicles not exempt from inspection, the owner needs to bring a power of attorney, the driving license, and the compulsory traffic insurance policy to the local motor vehicle inspection station for inspection; 3. It is no longer necessary to apply for an inspection qualification mark. After passing the inspection, the endorsement will be directly noted on the supplementary page of the driving license.

What is the solution for abnormal noise from car rubber bushings?

The solutions for abnormal noise from car rubber bushings are: 1. Disassemble the rubber bushing, wrap a layer of polytetrafluoroethylene plastic film on the stabilizer bar, apply grease, and reinstall the rubber bushing; 2. Replace the rubber bushing. The method for pressing in the small rubber bushing of the lower control arm is: 1. Apply lubricating paste on the lower control arm and the rubber bushing before pressing it in to facilitate installation; 2. Press the rubber bushing in at an angle. Once the outer edge of the rubber bushing is successfully inserted, use a hammer to assist in hammering it down, pressing it in at an inclined position. The replacement method for the control arm rubber bushing is: 1. Lift the car with a jack and remove the rubber bushing; 2. Remove both ends of the triangular arm, select a metal sleeve of the corresponding size, and install the rubber bushing; 3. Remove the screw, then use fire to burn out the middle metal sleeve after removal; 4. If the screw is not long enough, add a rubber bushing. Once it is almost in place, use an adjustable wrench with a shim to allow the rubber bushing to smoothly reach its position.

Are Compact Cars Bigger Than Subcompact Cars?

Compact cars are larger than subcompact cars. The classification of subcompact or compact cars is based on the vehicle's length and wheelbase. Generally, cars with a body length less than 4200mm and a wheelbase under 2620mm are classified as subcompact cars, while compact cars have a body length between 4200mm and 4600mm and a wheelbase between 2620mm and 2700mm. Subcompact cars typically refer to A0-segment cars within the A-class category. These cars usually have a wheelbase ranging from 2.2 to 2.3 meters (some models may fall outside this range) and an engine displacement between 1.0 and 1.3 liters. Common examples of subcompact cars include: Xiali, Swift, and MG 3SW. Subcompact cars generally have low fuel consumption and a compact design, offering a more comfortable and spacious interior compared to microcars. Compact cars typically have a larger exterior and interior space than subcompact cars, allowing them to accommodate more passengers. Compact cars, also known as A-segment cars, are the most common family cars, with a wheelbase usually between 2.5 and 2.7 meters and an engine displacement around 1.6 to 2.0 liters. In the domestic market, compact cars include models from domestic brands, joint ventures, and pure imports. Common examples of compact cars include: Buick Excelle, Chevrolet Cruze, Hyundai Elantra, Nissan Sylphy, Mazda 3, Volkswagen Lavida, Bora, and Ford Focus.

What does ETC mean in Chinese?

ETC in Chinese stands for Electronic Toll Collection, which is an automatic toll collection system for highways or bridges. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. During free holiday periods, vehicles can still use the highways. For users who have installed ETC, passing through ETC lanes will not incur charges. ETC's charging principle: There will be one or more ETC lanes on the highway. Through microwave dedicated short-range communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle with the bank in the background, achieving the purpose of vehicles not needing to stop at toll stations to pay tolls. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Saves time: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Saves wear and tear: Reduces costs, decreases the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improves efficiency: The efficiency of passing through ETC lanes can theoretically increase by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal of "reaching a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation development directions, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the vehicle in front from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle in front. The recognition speed for passing through ETC lanes is 20 km/h. If the speed is too fast, the vehicle's device information cannot be read, leading to charging failure. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. Non-human-induced loosening or detachment only requires reactivation. When using a debit card bound to ETC, insufficient balance will also cause charging failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive thickness of the car windshield can cause poor sensing. This is especially important for vehicles that have had accidents and had their windshields replaced or for those who have modified their front windshields.

Why Does a Diesel Engine Emit Black Smoke?

Here are the main reasons why a diesel engine emits black smoke: 1. Poor diesel quality—the diesel used does not meet the required performance standards, leading to incomplete combustion and black smoke; 2. Clogged air intake—insufficient air supply during diesel combustion results in incomplete combustion, causing the diesel engine to emit black smoke; 3. Insufficient compression—failure to achieve the required pressure for combustion worsens combustion conditions, leading to black smoke; 4. Changes in the combustion environment—long-term use of the diesel engine and other factors can alter the shape and volume of the combustion chamber, further degrading the quality of the fuel-air mixture. Poor combustion conditions then result in black smoke.

What is the normal position for the car oil dipstick?

The oil level is normal when it is between the two standard marks on the dipstick. Relevant information about engine oil is as follows: 1. Engine oil is the lubricant for the engine, which can lubricate the engine, reduce friction, assist in cooling, and minimize buffering. 2. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives improve and compensate for the shortcomings of the base oil. 3. Using engine oil can reduce wear on engine components and extend their service life. 4. The appropriate performance grade (quality grade) of engine oil should be selected based on the severity of the engine's operating conditions, additional devices in the intake and exhaust systems of imported vehicles, and the production year.
