Is it a violation to run a yellow light in a car?

Running a yellow light in a car is not considered a violation if any part of the vehicle has crossed the stop line; otherwise, it is a violation. Below is relevant information about running a yellow light: 1. Determination of running a yellow light: Drivers should slow down when approaching a yellow light. Vehicles that accelerate may be suspected of trying to run the yellow light. If any part of the vehicle has crossed the stop line when the yellow light is on, the vehicle can continue to pass, and it will not be considered running a yellow light. If the vehicle continues to move without having crossed the stop line, it will be deemed as running a yellow light. 2. Penalty for running a yellow light: The penalty for running a yellow light is the same as for running a red light, which includes a fine of 200 yuan. According to the 'Scoring Standards for Road Traffic Violations,' driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Therefore, drivers should always pay attention to changes in traffic signals, control their vehicles in time, and avoid committing violations.

How to Detect Cooling System Failures in Car Engines?

Methods for detecting cooling system failures in car engines include: 1. Check if the shutters are closed or have insufficient opening; 2. Inspect the tightness of the fan belt; 3. Verify the normal operation of the fan clutch and the correct direction of the fan blades; 4. Examine the working efficiency of the water pump. The causes of cooling system failures in car engines are: 1. Shutters being closed or having insufficient opening; 2. Slippage of the radiator fan belt or damage to the fan blades; 3. Poor performance of the temperature control switch for the electronically controlled fan; 4. Low rotational speed of the axial flow blower in the cooling system, obstructed air ducts, or poor air diversion.

How to Identify Genuine vs. Fake Engine Oil?

Methods to identify genuine engine oil are as follows: 1. Check the oil cap: High-quality engine oil caps usually have neat and smooth edges, with a one-time sealing cap. If the cap appears rough, lacks a "pull-tab" seal, or can be directly unscrewed, it is likely repackaged oil. 2. Look for the anti-counterfeit code on the container: Genuine oil containers have clear anti-counterfeit codes. Fake oil may lack such codes or have blurry ones that can be easily rubbed off. Many legitimate oil manufacturers provide various anti-counterfeit verification methods, such as anti-counterfeit labels, QR codes, product serial numbers, special markings, official websites, customer service hotlines, SMS verification, etc. Diligent verification can help avoid purchasing fake oil. 3. Examine the container material and craftsmanship: Genuine products have intact materials and clear printing, while counterfeit ones often have rough edges and uneven surfaces.

What Are the External and Internal Air Circulation Modes in Cars?

External air circulation in cars refers to: when the car's air conditioning system is turned on and connected to the outside air, it draws in air from outside the vehicle for circulation. Internal air circulation refers to: when the air conditioning system is turned off from external air intake, it can only use the air inside the vehicle for circulation. The icon for external air circulation is a car with an unenclosed arrow pointing from outside into the car, and its function is to replenish fresh air and improve the air quality inside the vehicle. The icon for internal air circulation is an enclosed car with a circular arrow inside, and its function is to promptly prevent external dust and harmful gases from entering the car. The usage methods for external and internal air circulation are: use external circulation on highways, and use internal circulation in traffic jams.

What does AWD mean on a car?

AWD on a car refers to the All-Wheel Drive system, which is commonly equipped on off-road vehicles and high-performance sedans. The All-Wheel Drive system is a driving device where all four wheels independently propel the vehicle at all times. It distributes driving force to all four tires through a central differential and independent differentials on the front and rear axles. The functions of the All-Wheel Drive system are: 1. On hard surfaces or during rainy turns, the speed difference between the front and rear wheels is absorbed by the central differential, providing more reliable four-wheel traction; 2. On snowy, icy, or swampy terrain, the central differential is locked, and it is unlocked when returning to normal road conditions.

What are the differences between manual transmission cars and automatic transmission cars?

Manual transmission cars and automatic transmission cars differ in the following aspects: 1. Different operation difficulty: Manual transmission cars rely on the driver to press the clutch to complete gear shifting operations; Automatic transmission cars rely on the hydraulic transmission automatic shifting principle of the torque converter to complete gear shifting. 2. Different safety: Coasting in neutral gear in manual transmission cars will cause the vehicle to lose power, resulting in understeer during turns; Automatic transmission cars cannot drive in neutral gear, maintaining power support throughout the entire journey for enhanced safety. Manual transmission cars use manual shifting mechanical transmissions to adjust speed. Automatic transmission cars do not require the driver to shift gears manually, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.
