Installing side steps on a car is not considered illegal modification. Here is an introduction to illegal car modifications: 1. Illegal modification refers to altering the appearance, power, braking system, or body color of a car. 2. According to relevant provisions of the "Motor Vehicle Registration Regulations," if the owner changes the body color, model, performance, purpose, or structure of a licensed motor vehicle, or replaces the frame, body, or engine, they must apply for modification registration with the vehicle management office. Failure to register or modify the vehicle may result in point deductions or fines. 3. Installing side steps not only enhances the overall coordination and aesthetics of the car but also makes it easier for the elderly and children to get in and out. Large SUVs have larger dimensions and higher bodies, making it inconvenient for the elderly and children to board. Side steps significantly improve accessibility and also provide some protection to the car body, preventing scratches to the paint. 4. Some regions do not allow the installation of side steps. If the installed steps do not match the photos on the vehicle's registration certificate, the car may fail the annual inspection. If the owner has already installed side steps, it is recommended to remove them before the annual inspection and reinstall them afterward.

As a seasoned car enthusiast who frequently tinkers with vehicles, I must say installing side steps isn't outright illegal, but it depends on regional regulations. In most parts of China, if the side steps don't significantly alter the original vehicle structure, don't extend beyond the body width excessively, and don't obstruct headlights or license plates, they're generally considered legal modifications. You're installing them to assist elderly family members or children boarding, which is particularly practical for high-riding SUVs. When installing, ensure you choose compliant products and avoid unauthorized suspension modifications or anything compromising driving safety – otherwise, traffic police may deem it illegal during roadside checks. I've seen friends purchase cheap online parts recklessly, only to fail vehicle inspections later, wasting both money and effort. My advice: first check local traffic regulations or have them professionally installed to ensure everything's above board.

How to Remove a Written Warning from Traffic Police?

Written warnings from traffic police cannot be removed. Here are the details: 1. Content of the written warning: The warning notice is essentially the "Traffic Management Administrative Penalty Decision" issued by the traffic police department. It records the offender's name, phone number, ID number, license plate number, and the violation. It also states that a warning penalty will be imposed in accordance with Article 88 of the "Traffic Law." 2. Purpose of the written warning: A written warning does not involve fines or demerit points but will be recorded. If the same violation is committed again and another written warning is issued, the two warnings can accumulate to result in fines and demerit points. 3. Penalty regulations: Article 88 of the "Road Traffic Safety Law" stipulates that penalties for road traffic safety violations include warnings, fines, temporary suspension or revocation of a motor vehicle driver's license, and detention.

How to Calculate Tire Age?

Tire age is generally marked on the outer side of the tire, and the production date can be obtained from the last four digits of this marking. Below are specific details about automotive tire specifications: 1. Specification Model Representation: Tires are crucial components of a vehicle, and they come in various specification models, each suitable for different types of vehicles. The specification model is usually indicated on the sidewall of the tire through a series of alphanumeric characters, representing the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed Rating: Based on the maximum speed they can sustain, tire speed ratings are categorized into different levels from A to Z, with level A further divided into eight sub-levels from A1 to A8. Generally, the later the letter representing the tire's speed rating appears in the alphabet, the better the tire's performance.

Will the lack of coolant affect the engine in a car?

Yes, the lack of coolant will affect the engine in a car. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and inhibiting scale and corrosion throughout the year. How to replace coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. Coolant flows through the five-way hose and is then distributed to different parts of the car to function. If there is any leakage of coolant in this section, replace the hose or re-secure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continuously flush it through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink color. Continue adding clean water until the drained water runs clear. Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add new coolant through the radiator hose. Then, add another container of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "MAXT" mark on the reservoir.

Is it correct not to release the brake pedal when ABS is active?

It is correct not to release the brake pedal when ABS is active. Here are the specific details about the ABS system: 1. Function of ABS system: ABS is the vehicle's anti-lock braking system, which belongs to the active safety system of the car. When the ABS light comes on, it indicates that the car's computer has detected a fault in the ABS system. 2. Principle of ABS light: Under normal driving conditions, ABS remains dormant. It only activates during emergency braking, such as when braking hard at high speeds. The car's computer determines this situation, and ABS intervenes to work. When the ABS light comes on, it is mostly because the speed sensor of the tire is not functioning properly. The ABS computer cannot recognize the driving conditions of each tire and cannot compare the slippage of each wheel, causing the ABS system to fail to work properly.

Can Low-Speed Electric Cars Be Equipped with Air Conditioning?

Low-speed electric cars can indeed be equipped with air conditioning. This system consists of a compressor, an internal heat exchanger (also known as an evaporator), an expansion valve, an external heat exchanger (also known as a condenser), internal and external fans, and a control unit. The function of car air conditioning is to provide cooling or heating, serving as a comfort feature that enhances the driving or riding experience. Broadly defined, low-speed electric vehicles can include electric bicycles, electric motorcycles, electric tricycles, and low-speed electric cars. Low-speed electric cars refer to simple four-wheel pure electric vehicles with speeds below 70 km/h. To drive an electric car, the driver must possess a Class C driver's license. Driving without a license is prohibited, and if caught by traffic police, the driver will face penalties.
