How to Understand Traffic Signals?

Green means go, red means stop, and yellow warns of an impending signal change. Below is relevant information about traffic signals: Green Light Signal: The green light is a permission-to-proceed signal. According to the "Regulations for the Implementation of the Road Traffic Safety Law": When the green light is on, vehicles and pedestrians are permitted to proceed, but turning vehicles must not impede the passage of through vehicles or pedestrians. Yellow Light Signal: When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. The yellow light signal's meaning lies between the green and red signals, having both a prohibition and permission aspect. When the yellow light is on, it warns drivers and pedestrians that the passage time is ending and will soon switch to red. Vehicles should stop behind the stop line, and pedestrians should not enter the crosswalk. Red Light Signal: Stop driving.

How to Align the Car Body in Subject 2 Exam?

Before officially performing the reverse parking and garage shifting in Subject 2, practice driving straight more to get a feel for the car; understand the principles of car movement and control the speed well; beginners are not very familiar with steering corrections, so controlling the speed well can buy time for angle adjustments. Find good reference points. When entering the parking space, observe through the rearview mirror whether the distance between the car body and both sides of the garage is roughly equal. When you see in the rearview mirror that the car body is parallel to the garage boundary line, your car body is aligned. When reversing, steer in the direction you want to correct. When exiting the parking space, observe through the rearview mirror whether the car body is parallel to the 7-meter line. If it is parallel, your car body is aligned.

When Can I Schedule the Subject Three Driving Test?

Normally, the time interval between scheduling Subject Two and Subject Three is about 7 to 10 days. If you fail the Subject Two test of the motor vehicle driver's license, the waiting time to schedule Subject Three will be extended by an additional 7 to 10 days. Both Subject Two and Subject Three are crucial tests for obtaining a motor vehicle driver's license, each offering five attempts. Relevant information about the driver's license test is as follows: Introduction: The driver's test is a qualification examination organized by the Vehicle Management Office of the Public Security Bureau. Only by passing the driver's test can one obtain a driver's license and legally operate motor vehicles. Content: The motor vehicle driver's test consists of three parts: the traffic safety laws, regulations, and related knowledge test (commonly known as the "theory test" or "Subject One"), the field driving skills test (commonly known as the "parking test" or "Subject Two"), and the road driving skills and safe civilized driving knowledge test (commonly known as the "road test" or "Subject Three"). The test content and passing standards are uniform nationwide, with corresponding test items specified according to different types of vehicles eligible for driving.

What does the automatic light mode mean?

Automatic light mode refers to the function where the car's headlights automatically turn on or off when the light-sensitive control system detects that the external light intensity is greater or less than a certain value. Below are the specific details about automatic headlights: 1. Working principle: The sensor consists of electronic components such as photoresistors, which send electronic signals to the ECU to control the turning on or off of the headlights, as well as the switching between high and low beams. When driving and encountering a sudden dark environment, the headlights will automatically turn on. They will automatically turn off when there is sufficient light. During nighttime driving, they will also automatically switch between high and low beams. 2. Function: Automatic headlights can turn on automatically when the owner forgets to turn them on, eliminating the need to manually switch them on when necessary. They can also automatically turn off based on the light intensity.

Can You Shift Directly from Second Gear to Neutral?

Yes. Here is some additional information about gear shifting: 2. Driving for long periods in low gear. Generally speaking, high gears are more fuel-efficient than low gears. Therefore, you should shift up promptly after starting. 3. Not fully depressing the clutch when shifting, which can damage the gears. Additionally, avoid resting your foot on the clutch pedal, as this can cause excessive wear on the release bearing. 4. The car veers off course when shifting. 5. Forcing the gearshift when it doesn't engage smoothly. 6. Rocking the gearshift back and forth when in neutral. This can cause unnecessary wear on components and affect the timing of gear shifts. 7. Skipping gears when upshifting. Upshifts should be done sequentially to prevent loss of power, while downshifts can skip gears. 8. Engaging reverse gear before the car has come to a complete stop. This can easily damage the gears.

What are the differences between 5W30 and 10W40?

The main difference between 5W30 and 10W40 is their viscosity. 10W40 oil has a higher viscosity, while 5W30 oil has a relatively lower viscosity. Additionally, 5W30 oil can adapt to lower temperatures compared to 10W40. 5W30 and 10W40 are SAE grades that indicate the viscosity of the oil. The "W" stands for winter, and the number before it represents the lowest environmental temperature at which the oil can be used. A lower number indicates better engine protection during cold starts. There are also differences in the types of vehicles that use these two oils: High-viscosity oils (with higher values) may be more suitable for high-speed driving or heavy-load vehicles. For older vehicles, using 10W-40 oil may result in slightly louder engine noise compared to 5W-30. The viscosity of engine oil changes with temperature, so it's important to pay attention to its performance under both low and high temperatures. For 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity: 0W is -35°C; 5W is -30°C; 10W is -25°C; 15W is -20°C; 20W is -15°C; 25W is -10°C. Better low-temperature fluidity ensures smoother cold starts for the vehicle. The number after the "W" represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. Generally, better low-temperature fluidity ensures smoother cold starts and better engine protection. Engine oil viscosity should not be too high or too low. If the viscosity is too low, it can increase engine wear. If the viscosity is too high, it can increase engine resistance during operation, leading to reduced engine power and increased fuel consumption. When the engine is running, the oil forms a film on the surfaces of engine components, reducing friction and lowering resistance. If the oil viscosity is too low, it cannot form a stable film, which can accelerate engine wear. For full synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is shorter, typically every 7,000 kilometers or six months. When choosing engine oil, consider the following: Select oil based on the engine's requirements. There's no need to use overly advanced oil for engines with lower requirements, nor should you use lower-grade oil for engines with higher requirements. Multigrade oil is recommended because it is economical, long-lasting, and efficient, providing better protection for the engine. Due to its properties, multigrade oil may appear darker and have lower oil pressure than conventional oil during use, which is normal. Since oil significantly affects engine performance and lifespan, always follow the vehicle's manual to select oil of the same series, service grade, and viscosity grade. The oil recommended in the vehicle manual is based on the engine's performance and the climate of the sales region, providing guidance with a considerable safety margin.
