Jiangyin Vehicle Management Office: Hello, my driver's license has been promoted to B 1 for more than a year. Why do I have to review it after receiving the text message? Isn't it once every six years? It should be that you originally held the certificate of C 1, and later added the certificate of B 1, so you should conduct the annual review according to the certificate of B 1. According to the Measures for the Use and Application of Motor Vehicles, the C 1 license is not subject to annual examination, but the driver's license will be renewed during the renewal period. The first license is valid for 6 years, so the license is renewed after 6 years. However, according to the regulations, the B 1 certificate must be verified once every two years, and a new driver's license is required when it is renewed.

Note: If your C 1 driver's license is less than 6 years old and you need to increase your B 1 driver's license, then the time to renew your driver's license will start from the time you first obtained it. If you have changed your driver's license for C 1 once, your current validity period is 10, which is the same as adding a driver's license.
