Is an Annual Inspection Required for a Class B License?

B2 licenses require an annual inspection. According to regulations, a B2 driver's license must undergo an annual review. However, if there are no demerit points recorded within a scoring cycle, the inspection for that cycle is exempted. The B2 driver's license is subject to an annual inspection, which must be completed within 30 days after the end of the current scoring cycle at the local vehicle management office where the license was issued. Below are the procedures and precautions for the B2 annual inspection: Annual Inspection Procedures: The applicant must submit the required materials directly to the receiving window. Organize learning and education sessions for drivers, lasting no less than three hours, and maintain records. For drivers who have participated in the learning and education sessions, a certificate of completion will be issued. The receiving window will accept applications that meet the requirements; if the materials are incomplete or do not meet legal requirements, the applicant will be informed of the missing materials or the reason for rejection. After approval, an inspection certificate will be issued. Annual Inspection Precautions: For driver's licenses that have not undergone the annual inspection within the stipulated time, if the delay is less than three years, the driver must pass a traffic regulations theory test before the annual inspection can be resumed. For licenses that have not been inspected for more than three years, the driver must have the license revoked by the traffic police department, then personally apply to a local driving school. After passing the theory test, "pole test," and "road test" administered by the public security traffic police department, the driver can regain the license.

What are the reasons for unclean car window wiping?

Reasons and solutions for unclean car window wiping: 1. The glass is too dirty. This is due to excessive dust. Spray more windshield washer fluid and wipe several times to clean it thoroughly. Always use washer fluid when wiping. 2. There is oil on the glass. If the car is parked in a place with oil fumes or if insects have collided with the glass, oil residue may be present. Oil is generally not easy to remove and usually requires car wash soap or foam cleaner to clean. 3. The wiper blade has oil. Many people forget that the wiper blade can also accumulate oil. After cleaning the glass, it is necessary to clean the wiper blade as well. This will make the cleaning more effective. The cleaning method is the same as above. 4. The wiper blade is damaged. This does not only refer to physical damage. Sometimes the wiper blade may be deformed, not adhering tightly to the glass, or not fitting closely during wiping. In such cases, it is best to replace it with high-quality parts. 5. The wiper motor is damaged. Besides being burnt out, the motor may have excessive gaps, causing the wiper blade not to adhere tightly to the glass. This can be detected through careful observation. 6. Not using windshield washer fluid. It is necessary to use washer fluid as it provides much better cleaning effects. Many people use water or water mixed with a little washer fluid. However, water is not very clean and does not effectively clean the glass.

What are the reasons for the non-responsive remote key of the Soueast DX7?

The reasons for the non-responsive remote key of the Soueast DX7 include a dead battery and the presence of high-power radio signals of the same frequency in the vicinity. Below are the relevant explanations: 1. Dead battery: This causes the vehicle to fail to receive signals; a depleted car remote key battery prevents the doors from being unlocked. 2. Presence of high-power radio signals of the same frequency in the vicinity: This makes the car's frequency signal receiver unable to detect the radio-encoded commands sent by the remote key. As a result, the car remote fails, leading to situations where the doors cannot be locked or unlocked. 3. Additional information: Solutions for sudden malfunction of car remote keys: Every remote key comes with a mechanical key, which can be used to manually unlock the car doors.
