How is the validity period of a driver's license regulated?

Here are the specific regulations regarding the validity period of a driver's license: Within one year before expiration: The driver should apply for a license renewal at the vehicle management office within 90 days (three months) before the expiration of the driver's license. The license can still be renewed normally within one year after expiration. Between one and three years after expiration: The driver's license will be revoked, and the driver needs to retake the subject one exam to obtain a new license. If the driver's license has been expired for more than three years, it will be directly invalidated. The initial renewal period for a driver's license is 6 years. If no demerit points have reached 12 points in any cycle during these 6 years, a 10-year validity period driver's license will be issued upon renewal. If there is a case where 12 or more demerit points have been recorded within a year, a 6-year validity period driver's license will still be issued. When the 10-year driver's license expires, if no demerit points have reached 12 points in any cycle, a long-term valid driver's license can be issued.

Which Button to Press for Foggy Car Windows?

Causes of foggy car windows: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing moisture to gather on the glass surface and form tiny droplets, resulting in fog. Methods to defog car windows: For manual air conditioning, turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and then set the temperature to the lowest. Wait a moment, and the fog on the windows will disappear. Some models are equipped with rear window electric heating and external rearview mirrors; simply press the switch, and the fog will clear in about a minute. For automatic air conditioning, generally just press the one-touch defrost button, set the fan speed to maximum, and turn on the external circulation. The fog on the car windows will disappear shortly. Press the defog button, turn on the A/C switch, set the temperature to the lowest, and turn on the external circulation to defog. Both cold and warm air can be used to defog car windows, but warm air is slower than cold air. The most effective method is to use cold air, as it blows dry cold air directly onto the glass, preventing water vapor from condensing and achieving defogging. The method for warm air defogging is the same as cold air, but note that warm air should not be used on rainy days, as it may initially worsen the fog. Always use external circulation when defogging car windows. Air conditioning cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car, if the air conditioning is not turned on promptly, the high humidity from exhaled breath can quickly cause the windshield to fog up. In this case, turn on the air conditioning to blow cold air onto the windshield, using the dehumidification function to quickly remove the fog. If the humidity is too high and the air conditioning is ineffective, slightly open a window to rapidly reduce the humidity inside the cabin. Combining this with the air conditioning will yield faster results. Air conditioning heating: Use the method of reducing the temperature difference to remove fog. In winter, blow warm air onto the glass to quickly raise the temperature of the front windshield, reducing the temperature difference between the inside and outside surfaces and preventing excessive fogging. However, note that the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether using automatic or manual air conditioning, turning it on helps with dehumidification. Avoid setting the air conditioning temperature to the coldest setting, as prolonged use may cause the outer surface of the windshield to fog up. Applying anti-fog spray or other preventive measures: Spray a small amount of defogging agent onto the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film forms, effectively preventing moisture from condensing on the glass and forming fog. This is especially useful in cold winters. Alternatives to defogging agents include dish soap, soapy water, glycerin, alcohol, or saline solution. After applying, let it dry and then wipe off excess residue with chamois or a soft dry cloth. This will keep the windows fog-free for several days. Opening windows for convection: If the fog inside the car is not too thick, you can open the side windows to allow air convection between the inside and outside of the car, reducing the temperature difference and gradually dissipating the fog. The principle of this method is the same as using cold air from the air conditioning. However, the drawbacks of opening windows for convection are obvious: it cannot be used during rain or snow, on highways, or when the fog is too heavy.

What is the best position to install the ETC device on a truck?

The ETC installation position is generally in the upper middle part of the front windshield horizontally, while for large vehicles such as trucks and buses, the installation position is in the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with explosion-proof film or those that have it installed later, which may affect the signal transmission of the microwave communication link, it should be installed in the microwave sunroof strip. ETC is the abbreviation for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; the vehicle that needs to install ETC. Here are some considerations for ETC installation: Do not block the view; it is best to install it behind the rearview mirror: Many vehicle models have a large tilt angle on the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced because it has a solar panel on the back that can charge itself. Therefore, when installing, avoid the black areas on the windshield and do not place it where it might block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed on the windshield, the anti-removal lever will be pressed in. If it is removed casually, the lever will pop out and trigger the switch, locking the electronic tag and making it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.

Is a 12V Car Battery Normal?

Car battery voltage of 12V is normal, generally ranging between 11.8V and 12.8V. Regular Maintenance: The battery also requires regular maintenance. If poor power supply is detected, avoid using vehicle power sources such as electric air pumps, audio systems, warning lights, or power windows before starting the car. Proper Usage: During daily vehicle use, avoid situations with large current fluctuations, as this can accelerate battery aging. Battery performance changes are inevitable, so regular inspection and maintenance are essential to promptly identify abnormal battery degradation and address any issues immediately.

Is the Warranty Still Valid After Engine Repair During the Warranty Period?

The car warranty period refers to the time frame during which the car manufacturer promises to provide free repairs and maintenance for faults caused by quality issues when selling the product to consumers. Currently, our country mandates that manufacturers provide an engine warranty of no less than 40,000 kilometers or two years. Most car manufacturers now offer engine warranties that meet or exceed the national minimum requirements. However, there are no specific regulations regarding the warranty for engines after major repairs. In the automotive industry, it is common practice to provide only a 1-month or 1,000-kilometer warranty for engines after major repairs. Some manufacturers may extend this to a maximum of three months, but most repair stations only offer a 1-month warranty after an engine overhaul.
