Can the reasons for failing the subject three exam be checked?

Subject three exam failure reasons can be checked, usually the on-site announcement will directly report the reason for disqualification. Subject three, including the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment, and is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's test. The road driving skills test content varies for different types of driving licenses. The following is an introduction to the subject three exam content: 1. Introduction to subject three: Subject three includes the road driving skills test and the safety and civilized driving knowledge test, which is part of the motor vehicle driver's license assessment, and is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's test. The road driving skills test content varies for different types of driving licenses. 2. Subject three exam content: The road driving skills test content of subject three generally includes: preparation before getting on the car, light simulation test, starting, driving straight, shifting gears, changing lanes, parking on the side, passing through intersections straight, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school areas, passing through bus stations, meeting cars, overtaking, turning around, and driving at night; the safety and civilized driving knowledge test content generally includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge of handling after traffic accidents.

What is the plastic under the car door?

The plastic under the car door is the side skirt. Below are the functions of the car side skirt and methods to prevent it from rusting: Functions of the car side skirt: The side skirt refers to the skirt panel installed on both sides of the car body, which also acts as an air dam, reducing the airflow entering the underside of the car from the sides. It has a certain turbulence effect, significantly reducing air resistance. At high speeds, it enhances driving stability. When the car is running at high speeds, it prevents the vehicle from drifting. Methods to prevent the car side skirt from rusting: Try to park the car indoors; ensure the vehicle is parked in a dry environment; promptly clean sludge from gaps and the floor inside the car.

What to Do When a Vehicle Skids?

Here are the steps to handle vehicle skidding: 1. First, firmly hold the steering wheel and reduce the throttle as needed. 2. Quickly determine the nature of the skid, such as whether it's front-wheel skidding or rear-wheel skidding; whether it's caused by poor road conditions or improper operations like braking or steering. 3. Avoid panicking and do not blindly steer based on instinct alone. Below are the common causes of skidding: 1. Slippery, oily, or icy roads; these reduce the coefficient of friction and create asymmetry between the left and right sides, lowering the wheel load and road adhesion. Even slight lateral force can cause wheel skidding. 2. Uneven resistance during braking; factors such as unequal braking force on left and right wheels, varying coefficients of friction, or uneven load distribution can lead to "pulling" and easily result in wheel skidding. 3. Overly aggressive actions, such as excessive braking, can cause wheels to "lock up and drag," with rear wheels typically locking up before the front wheels, also leading to skidding. 4. Improper steering operations; for example, high speed, sudden steering, improper braking during sharp turns, or a high center of gravity (overloaded cargo) can increase centrifugal force, making wheel skidding more likely.

Can You Add Oil When the Car Is Low on Engine Oil?

You can add oil when the car is low on engine oil. Engine oil plays a crucial role in the lubrication system of the engine. However, engine oil cannot be used indefinitely in a cycle. Cars require regular oil changes or top-ups; otherwise, insufficient oil can lead to adverse effects on the vehicle. Engine oil, which is the lubricant for the engine, provides insufficient lubrication when it is low, increasing friction resistance and accelerating wear on the engine and its components. Prolonged oil deficiency can, in severe cases, cause the engine to overheat, leading to severe mechanical failures in moving parts, reducing the engine's lifespan, or even resulting in engine failure.

Do New Cars Need Antifreeze?

New cars do not require additional antifreeze. Since new vehicles come with factory-installed antifreeze, it is generally sufficient to replace the antifreeze every two years or every 30,000 kilometers. The method for replacing antifreeze is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. Antifreeze flows through the five-way hose and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this area, replace the hose or resecure the connection as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir and continue to fill it until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir will have a faint pink tint. Continue adding clean water until the water coming out is clear. Note: Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose. Then, add another container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop as air is expelled from the cooling system. Add more antifreeze until the level reaches the "MAXT" mark on the reservoir.

How Many Levels Can Passenger Cars Be Divided Into?

According to the detailed domestic classification, passenger cars can be divided into 6 levels, generally categorized as: A00, A0, A, B, C, and D. Below is a related introduction to each level of passenger car: 1. A00-class passenger cars have a wheelbase between 2 meters and 2.3 meters, with an engine displacement of less than 1 liter. 2. A0-class cars have a wheelbase of 2.3 meters to 2.5 meters and a displacement of 1 liter to 1.5 liters. Common models like the Sail and Fit belong to the A0 class. 3. A-class cars have a wheelbase ranging from approximately 2.5 meters to 2.7 meters, with a displacement of about 1.5 liters to 2.0 liters. Models like the Sagitar and Focus fall into this category. 4. B-class cars are slightly higher than A-class, also known as mid-size cars, with a wheelbase of about 2.7 meters to 2.9 meters and a displacement ranging from 1.8 liters to 2.5 liters. This is currently a highly competitive segment. 5. C-class cars belong to the premium passenger car category, with a wheelbase of approximately 2.8 meters to 3.0 meters and an engine displacement of 2.3 liters to 3.0 liters. Typical C-class models include the Toyota Crown and Mercedes-Benz E-Class. 6. D-class cars can be considered the true luxury car segment, mostly used for business purposes, offering excellent ride comfort. D-class cars have a very long wheelbase, generally exceeding 2.8 meters, with an engine displacement of over 3.0 liters.
