Does Fatigue Driving in a Sedan Result in Demerit Points?

Fatigue driving results in a deduction of 6 points. More related information is as follows: 1. When driving a vehicle: As speed increases or during prolonged high-speed driving, drivers may experience varying degrees of fatigue. When driving at high speeds, the driver's attention is highly focused, leading to continuous mental strain. As speed and driving duration increase, fatigue gradually sets in. On highways, the monotonous road environment, minimal traffic interference, stable speeds, and low noise and vibration frequencies can induce drowsiness, known as the "highway hypnosis effect." Thus, high-speed driving is prone to causing driver fatigue. 2. When fatigued, a driver's judgment declines, reactions slow, and operational errors increase: Mild fatigue may lead to delayed or inaccurate gear shifting. Moderate fatigue results in sluggish movements and occasional operational lapses. Severe fatigue can cause subconscious actions or brief sleep episodes, potentially leading to loss of vehicle control. Symptoms of fatigue include blurred vision, back pain, stiff movements, swollen limbs, lack of focus, slow reactions, poor decision-making, mental distraction, anxiety, and irritability. Continuing to drive under such conditions may cause accidents. 3. Fatigue can generally be categorized as physical or mental: Based on recovery time, fatigue can be acute, chronic, or accumulative. Acute fatigue is temporary, caused by daily activities, and alleviated by short rest periods—normal driving fatigue falls under this category. Chronic fatigue stems from prolonged fatigue, reducing performance and affecting health; it cannot be resolved with brief rest. Excessive fatigue arises from repeated or continuous fatigue, potentially manifesting suddenly as illness. It cannot be remedied with short sleep and requires extended rest and ample sleep; otherwise, it may develop into chronic fatigue. Drivers experiencing excessive or chronic fatigue should avoid operating vehicles.

Reasons for Fogging in Car Headlights on Rainy Days

Fogging in headlights is normal. This is because there is a ventilation and heat dissipation rubber tube at the rear cover position of the headlight structure. It is also due to this rubber tube that moisture from the air enters the headlight and adheres to the lens, creating fog. In severe cases, water droplets may form. This situation is most likely to occur during winter and rainy seasons. Below is relevant information: 1. Mild Fogging: First, mild fogging occurs, and the reason for this type of fogging is only related to the humidity of the air. Generally, the amount of water vapor condensed in the headlight due to fogging is not much. The headlight assembly has several intake and exhaust holes, whose function is to balance the air temperature inside the headlight when it is turned on, allowing hot air to be expelled and cold air to be drawn in. 2. Severe Fogging: Severe fogging is usually caused by cracks in the headlight assembly, improperly fitted dust covers, holes in dust covers, aging sealing glue, etc. After driving, the temperature inside the headlight is still very high, and a large amount of highly humid air enters. If the outdoor temperature is relatively low, a layer of fog will condense inside the headlight assembly.

Why Can Turning on the Air Conditioning in a Car Be Fatal?

When the engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. While the car is moving, the air passing through the air conditioning system creates convection, keeping the carbon monoxide concentration inside the car low. However, when the car is stationary with the air conditioning still on and the windows and doors closed, the carbon monoxide emitted by the engine gradually accumulates, increasing its concentration, which can lead to poisoning or even death. Here are precautions for sleeping in a car with the air conditioning on: 1. Park in an open area: The car should be parked in an open space, preferably with the front facing the wind direction, so that even if the engine is not turned off, the exhaust will be blown away. If parked in a confined space like an underground parking lot, exhaust fumes can seep into the car. 2. Leave a window gap: When sleeping with the air conditioning on, leave a 2-3 cm gap in the window to prevent suffocation or carbon monoxide poisoning. However, the gap should not be too large to prevent potential criminal activity. 3. Use the air conditioning's external circulation mode: It is best to turn on the external circulation mode when sleeping in the car, as this mode draws outside air into the car, maintaining air circulation inside.

How many kilometers should the belt of Baojun 730 be replaced?

Baojun 730 belt replacement time is three years or 50,000 kilometers. The following is the relevant introduction to Baojun 730 belt replacement: 1. The replacement time for new cars can be appropriately extended. The fact that the timing belt is not broken does not mean there are no problems. As the belt ages, the degree of stretching will inevitably exceed the compensation range of the tensioning device, causing the timing sprocket to slip. Additionally, tooth wear and the presence of lubricating oil can also lead to slipping. 2. If the belt shows signs of reduced hardness, erosion, fiber breakage, cracks, or fissures, it indicates that the belt is damaged and should not be used further. The high temperature during engine operation, cooling after the car is stopped, oily impurities, and improper matching or installation of the timing belt tensioner can all shorten the service life of the timing belt. 3. The timing belt is responsible for the accurate coordination of key parts of the engine, so it is crucial for the normal operation of the engine. Once the timing belt is damaged, the valves and ignition will stop or malfunction, causing the engine to stop working. In severe cases, the cylinder head may also be damaged. 4. The timing belt is a consumable part. Once it breaks, the camshaft will not operate according to the timing, which is highly likely to cause severe damage due to the collision between the valves and pistons. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer.

What is the difference between L gear and S gear?

Here are the differences between L gear and S gear: 1. Different in nature: L gear is the low-speed gear, while S gear is the sports gear. 2. Different characteristics: In S gear sports mode, the gearbox delays the shift-up timing, keeping the engine at high speed for a longer time, allowing the car to move at high speed in low gear for a longer time, thereby obtaining greater torque output and acceleration. When L gear is engaged, the car will not shift up and will continue to move forward at high speed in low gear, making it better for towing cargo. 3. Different functions: L gear can be used to control speed, climb slopes with heavy loads, and increase traction when driving on muddy roads. S gear can be used for overtaking acceleration, fully releasing the engine's power.

What car does the 't' logo represent?

t is the logo of Tesla Motors. Here is an introduction to Tesla Motors: 1. Tesla is an American electric vehicle and energy company founded in 2003 by Martin Eberhard and Marc Tarpenning. The founders named the company 'Tesla Motors' in honor of physicist Nikola Tesla, with the brand vision of 'accelerating the world's transition to sustainable energy.' 2. The Tesla logo is the initial of physicist Tesla's name, also representing the cross-section of an electric motor. The main part of the letter 'T' represents a section of the motor rotor, while the second line at the top represents part of the outer stator. 3. Tesla released its first car model in 2008, the Roadster, a two-door sports car. In 2012, it launched its second car model, the Model S, a four-door all-electric luxury sedan. In 2015, it delivered its third car model, the Model X, a luxury all-electric SUV. 4. In 2017, Tesla Motors was renamed Tesla.
