What to Do If the Probationary Period of the Driver's License Has Expired for One Month?

If the driver's license is a Class C license and the demerit points do not exceed 12 within 12 months, it will automatically become a regular license upon expiration without any additional procedures. For Class A or B licenses, according to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," within 30 days after the probationary period ends, the holder must take a test on road traffic safety laws and regulations, safe and civilized driving, emergency handling, and other knowledge, and receive at least half an hour of case-based education on traffic accident warnings. Only after passing the test can the holder become a regular driver. Additionally, if a Class A or B license holder accumulates more than 6 but fewer than 12 demerit points during the probationary period, the probationary period will be extended by one year. If the holder again accumulates more than 6 points during the extended period, the probationary driving qualification for that vehicle type will be revoked. Extended Information: 1. After becoming a regular license, the validity period is 6 years. If no demerit cycle exceeds 12 points within these 6 years, the license can be renewed for a 10-year validity period. Similarly, if no demerit cycle exceeds 12 points within these 10 years, the holder can apply for a long-term valid license. 2. Obtaining a long-term valid license does not mean no further procedures are required. Holders of Class A or B licenses must switch to a Class C license at the age of 60 and can no longer drive large or medium-sized vehicles, only small motor vehicles. Furthermore, after the age of 70, license holders must submit a physical condition certificate within 30 days after the end of each demerit cycle to prove they meet the physical requirements for driving, which is also for the safety of the driver.

What does the mode in the car air conditioner mean?

The Mode on the car air conditioner refers to switching modes. If in the air conditioning mode, it is used to adjust the air outlet. For other functions, you can refer to the car manual. Additionally, when listening to the radio, CD, or external audio source, pressing the MODE button will synchronize the display between the tachometer and speedometer with the MMI system. Then, by pressing the button to the left of the MODE key, you can scroll through song selections on the central display screen. Pressing the scroll wheel down confirms the song change. Pressing MODE again switches back to normal mode. Other letter indicators on the car air conditioner are as follows: 1. A/C: The A/C button is the switch for the air conditioning compressor. Only when the compressor is turned on does the air conditioner have cooling capability. The A/C light indicates that the compressor is operating, allowing the vehicle's air conditioner to cool. 2. MAX: When the MAX function is activated, the car's air conditioner operates at full capacity with the fan at maximum speed. This function is only available in some models with automatic air conditioning. Pressing MAX causes the air conditioning compressor and fan to operate at maximum output to quickly reach the set temperature. 3. FRONT button: This is the front window defrost switch. When turned on, the air outlet blows air toward the front windshield. 4. REAR button: This is the rear window defrost switch. When turned on, the rear windshield's electric heating wire heats up.
