Is the Penalty for Not Wearing a Seat Belt Reasonable?

Not wearing a seat belt is subject to penalties. The penalties and hazards of not wearing a seat belt are as follows: Penalties for not wearing a seat belt: When driving on urban expressways, if the driver fails to use the seat belt as required, 2 points will be deducted. When driving on roads other than highways or urban expressways, if the driver fails to use the seat belt as required, no points will be deducted. When a motor vehicle is in motion, if passengers fail to use the seat belt as required, they may face fines, etc. Hazards of not wearing a seat belt: In the event of a vehicle accident or emergency braking, a significant inertial force is generated. Depending on the driving speed and the severity of the impact, this inertial force varies. The inertial force causes the driver and passengers to collide with objects inside the vehicle, such as the steering wheel, windshield, seat backrest, and doors, which can easily result in severe injuries to the occupants. In extreme cases, it may even throw the occupants out of their seats or eject them from the vehicle.

Should the AC be turned on when using car air conditioning in summer?

In summer, the AC should be turned on when using the car air conditioning. The AC button is the cooling switch for the car air conditioning system. If the AC button is not pressed, the car air conditioning will not provide cooling. Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The cooling principle of air conditioning is as follows: 1. After pressing the AC button, the clutch of the air conditioning compressor engages, allowing the engine to drive the compressor. During operation, the compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat. 2. The refrigerant cools the evaporator, which in turn cools the air blown by the blower, allowing the car air conditioning vents to blow cold air.

How long does it take to drive 12 kilometers?

How long it takes to drive 12 kilometers depends on factors such as the car's speed, model, and traffic conditions. Under normal circumstances, the speed of an economy car is between 60 to 80 kilometers per hour, so driving a distance of 12 kilometers would take about 10 minutes. In urban areas with normal traffic conditions, it would take around 20 to 30 minutes due to waiting at traffic lights. During peak traffic hours with congestion, it would take even longer. On highways, where speeds are around 80 kilometers per hour, driving 12 kilometers under good road conditions would only take about 6 minutes. The following factors determine the driving time: 1. Driving speed; 2. Traffic lights and congestion; 3. Car model; 4. Weather conditions, etc.

Where is the forward gear in an automatic transmission car?

In an automatic transmission car, D1, D2, and D3 are all forward gears. 1. D1 is generally used when climbing steep slopes (equivalent to first gear in a manual transmission). 2. D2 is typically used when ascending long slopes. 3. D3 is used on regular roads. 4. On current roads, D1 and D2 are rarely used as the speed is not fast even at high RPM. Below is some information about the D gear: (1) The "D" on the gear shift stands for Drive, which is the forward gear. (2) By placing the gear lever in the "D" position, the driver only needs to control the accelerator pedal to adjust the speed. (3) This gear is undoubtedly the most frequently used one, especially in automatic transmission models. The "D gear for all situations" is a driving mode favored by many drivers.

How to Deal with the Exclamation Mark with a Gear?

An exclamation mark inside a gear is the automatic transmission fault warning light, indicating a fault in the transmission or that the transmission lubricant is below the normal range. It is necessary to replace the transmission oil promptly. The exclamation mark is a common fault warning in cars. Besides the exclamation mark inside a gear, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark inside a circle with parentheses, an exclamation mark with a horizontal line below parentheses, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Brake System Fault: An exclamation mark inside a circle with parentheses. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, signaling a fault in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What does DPF light mean?

There are two situations when the DPF light is on. 1. The automatic catalytic cleaning of the diesel particulate filter will cause the DPF light to turn on. 2. A malfunction in the diesel particulate filter causes the DPF light to turn on. Classification of car dashboard indicator lights: 1. Red indicator lights: Red lights are generally danger warning lights. If these red indicators are lit and ignored, they can either have a significant impact on driving safety or cause considerable damage to the vehicle itself. 2. Yellow indicator lights: Yellow lights are malfunction indicator lights. When yellow lights on the dashboard are lit, they inform the driver that a certain system function of the vehicle has been lost. 3. Green indicator lights: Green lights are status indicator lights, showing the current working state of the vehicle. For example, the power mode indicator of an automatic transmission or the HINLO for body height adjustment does not warn the driver but indicates the current state of the vehicle.
