Will the validity period of driver's licenses be extended during the pandemic?

In the event of a pandemic, the validity period of learning driving certificates obtained before and during the pandemic will be uniformly extended, generally by three months. The following is relevant information about the vehicle license: 1. Introduction: The motor vehicle license is the legal document that permits a motor vehicle to drive on roads within China. The license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page is the signed certificate core, and the back is the photo of the motor vehicle, sealed in a plastic cover. The supplementary page is the signed certificate core. 2. Verification: The vehicle license verification system can verify the authenticity of the motor vehicle and query motor vehicle information to provide travel safety guarantees. By simply entering the basic information of the motor vehicle into the system, you can verify whether the motor vehicle is genuine. If the information matches, other details of the motor vehicle can also be verified.

Can a photo of the vehicle license be used to handle traffic violations?

Article 17 of the "Road Traffic Management Regulations" promulgated by the State Council stipulates: "Vehicles must pass the inspection of the vehicle management authority and obtain license plates and a vehicle license before they are allowed to operate." Therefore, possessing a "Motor Vehicle License" is one of the prerequisites for a vehicle to be driven on the road. Driving without carrying the vehicle license is a violation, regardless of whether the driver has not obtained the "Motor Vehicle License" or simply forgot to bring it. Hence, a photo of the vehicle license cannot be used to handle traffic violations. When dealing with traffic violation records, the driver must carry their ID card, driver's license, and vehicle license—all three documents are indispensable. The vehicle owner must take these three documents to the traffic violation office, submit them to the staff, who will then retrieve the violation information and display the photos for confirmation. After confirmation, the staff will print the penalty decision form, which the owner must take to the designated bank to pay the fine. Once the fine is paid, the violation record will be cleared. If the vehicle license is lost, the owner should first apply for a replacement. The owner can apply for a replacement at the local vehicle management office. The application requires the identity proof of the vehicle owner, a copy of their ID card, and a photo of the vehicle. If the application is handled by an agent, a letter of authorization and a copy of the agent's ID card must also be provided. The vehicle license must be kept in the vehicle at all times, as it is the legal document required for the vehicle to operate on the road. The vehicle license consists of three parts: the main page, the supplementary page, and the vehicle photo, which includes detailed configuration information of the vehicle. Therefore, it must be carried in the vehicle when driving.

What is the wading depth of the Envision?

The maximum wading depth of the Envision is approximately 300mm. The wading depth of the Envision is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, SUVs and off-road vehicles have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake of the Envision is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. The height of the air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct procedures should be followed: Before driving through water, always turn off the auto start-stop function to prevent the engine from automatically restarting if the vehicle stalls in water, which could cause severe damage due to water entering the engine. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at a low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, or other vehicles' wheels and doors as reference points to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not proceed and choose an alternative route instead.

How to Handle Changes in Driver Information?

To update personal information on a driver's license, you need to file a record at the vehicle management office. The following materials are required: Bring your ID card, household registration certificate issued by the local police station, driver's license, and two passport-sized photos. Go to the vehicle management office where the driver's license was issued to obtain the "Motor Vehicle Driver's License Application Form" and submit it along with the other documents to process the information change. Additional information: 1. Driving school registration time: Registering for a motor vehicle driver's license at a driving school takes about half an hour to complete. Afterward, wait for the driving school's notification for a medical examination. Once the medical examination is completed, you can begin studying for the driver's license theory test (Subject 1). After meeting the required study hours, you can take the exam. Other subjects must be completed in the same order. There is no need to repeat the medical examination within six months. 2. Time to obtain a driver's license: Under normal circumstances, it takes about 45 days to obtain a motor vehicle driver's license, with a maximum time limit of three years. The countdown starts after passing the Subject 1 exam. If this time limit is exceeded, the driver's license exam eligibility will be canceled, and you will no longer be able to take the exam.

Is Black Smoke from a Diesel Engine a Sign of Insufficient Power?

Black smoke from a diesel engine is related to the diesel fuel itself. Using diesel with the wrong grade, excessive viscosity, or poor quality can make it difficult to ignite, resulting in black smoke emissions. Additionally, this can lead to carbon buildup in the combustion chamber and exhaust muffler, causing the engine to emit black smoke. Precautions for electronically controlled diesel engines: 1. Use the correct grade of engine oil: Electronically controlled common rail engines have higher requirements for oil. It is essential to use CF-grade or higher oil to ensure smooth operation. Moreover, the oil filter should be replaced regularly to maintain oil cleanliness. 2. Replace filter elements periodically: Follow the recommended schedule to replace these filtration devices, ensuring the diesel fuel remains highly clean. Otherwise, if the engine's fuel injection system is damaged, the repair and replacement costs can be substantial. 3. Protect against water, dust, and impacts: Electronically controlled engines incorporate complex electronic systems to precisely manage fuel supply. However, these sensitive electronic systems require specific maintenance. During regular use, ensure the engine's electronic systems are kept away from heat sources and protected from water, dust, and physical impacts.
