How many points are deducted for overtaking by borrowing the opposite lane?

Borrowing a lane for overtaking is a normal driving behavior, but it depends on whether the road section allows overtaking. Otherwise, it is considered a traffic violation. According to regulations: driving outside the designated lane results in a 3-point deduction and a fine. Occupying the opposite lane results in a 12-point deduction. Cutting into a queue of waiting vehicles leads to a fine and a 2-point deduction. Below are precautions for highway driving: 1. Control driving speed: Speeding on highways is detrimental to driving safety. Higher speeds increase centrifugal braking distance and reduce vehicle handling stability. Additionally, excessive speed shortens the driver's sight distance and increases misjudgments. Therefore, controlling driving speed is the primary condition for ensuring highway operation safety. 2. Avoid low-speed driving: China's highways stipulate a minimum speed of no less than 60km/h during normal driving. Low-speed driving, on one hand, easily affects following vehicles in the same lane, preventing the highway from realizing its intended fast and efficient advantages; on the other hand, it can easily cause traffic congestion or disorderly driving conditions with consecutive overtaking by subsequent vehicles. 3. Avoid tailgating: Safe following distance should vary based on driving speed, weather, and road conditions. The faster the speed, the greater the following distance should be, especially during snow, rain, fog, or icy road conditions, where the distance should be doubled.

What is the unit of car engine displacement?

The volume of space through which the piston moves from top dead center to bottom dead center is called the cylinder displacement. Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Car engine displacement is an important parameter for measuring a vehicle. Some domestic cars do not have the aforementioned model designation on their rear, but their displacement is usually indicated on the body or rear of the car. If an engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, more representative of engine size than cylinder diameter and number of cylinders. Many engine indicators are closely related to displacement. Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), resulting in better "power performance." This is similar to comparing a teenager to a healthy adult—the adult is naturally more efficient at physical labor. Therefore, off-road vehicles and sports cars typically have relatively larger displacements. In China, the classification of car levels is determined by the size of the displacement. Mini cars have a displacement of ≤1.0L; compact cars have a displacement ranging from 1.0–1.6L; midsize cars have a displacement ranging from 1.6–2.5L; executive cars have a displacement ranging from 2.5–4.0L; and luxury cars have a displacement >4.0L.

What does a triangle with an exclamation mark displayed on the car mean?

The reasons for the decrease in coolant are: 1. Leakage in the engine cooling system; 2. Thermal expansion and contraction; 3. Air retention in certain areas of the cooling system, which causes coolant levels to drop after some time of circulation when the air is expelled. When the water temperature is too high, a triangle with an exclamation mark displayed on the car indicates a vehicle malfunction. This light is also known as the general fault indicator. Other warning lights with exclamation marks in the car include: 1. A red circle with an exclamation mark inside parentheses indicates the brake system warning light, which illuminates when the handbrake is engaged; 2. A yellow horizontal line with an exclamation mark below parentheses indicates the tire pressure monitoring warning light, which only lights up when the pressure in the four tires is unbalanced or too low; 3. An exclamation mark inside a yellow bulb indicates the lighting system fault indicator, which lights up when a bulb malfunctions; 4. An exclamation mark next to a red steering wheel indicates the power steering system fault indicator, which lights up when there is a malfunction or failure in the power steering system, such as a locked steering wheel. Driving issues may occur, and inspection and maintenance are required. Coolant, also known as antifreeze coolant, has antifreeze properties that prevent the coolant from freezing in cold weather, which could otherwise crack the radiator or damage the engine block. Antifreeze is not only for winter use but should be used year-round. As part of regular vehicle maintenance, the engine antifreeze should be replaced every year.

What is the tire size for Honda Jade?

Honda Jade has two tire specifications: 215/50R17 and 225/45R18. In 215/50R17, the first number 215 represents the tire width of 215MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 17 represents the rim diameter of 17 inches. The letter "R" in the middle stands for radial tire. In 225/45R18, the first number 225 represents the tire width of 225MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 18 represents the rim diameter of 18 inches. The letter "R" in the middle stands for radial tire. The tire brand for Honda Jade is Yokohama, and the spare tire specification is non-full size. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, the jack should be under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hub cover, loosen the nuts counterclockwise, do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn instead of the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, and completely remove the nuts; Place the new tire on the hub, carefully align the tire rim and wheel bolts, install the lug nuts, tighten the nuts by hand until all nuts are concealed, at this point the tire replacement is completed. In addition to the size, the tire also has the following common data marked on it: Tire cord material: represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed rating of the tire from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: indicates the rim specification compatible with the tire. For practical use, such as "Standard rim 5.00F".

How to Reset the Tire Pressure Light on a Ford Escape?

Press the setting button on the left side of the multifunction steering wheel, navigate to the tire pressure monitoring system in the settings menu, then long-press the setting button and save the tire pressure to reset the tire pressure warning light. Below is more information about automotive tire pressure: 1. Tire pressure is crucial for driving stability - it should neither be too high nor too low. 2. Overinflated tires reduce the contact area with the road surface, decreasing traction and negatively affecting vehicle handling and stability. 3. Underinflated tires may develop wave-like deformation during high-speed driving, which shortens tire lifespan and increases the risk of blowouts.

What Causes Gasoline to Enter a Motorcycle Engine?

Motorcycle engine ingesting gasoline is due to a malfunction in the carburetor. Introduction to the Engine: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including various types such as internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Engine Cylinder Arrangement: Cylinder arrangement, as the name suggests, refers to the layout of the cylinders in a multi-cylinder internal combustion engine. Simply put, it is the queue form formed by the cylinders on an engine.
