Those who have obtained a driver's license for the first time for more than 5 years can add it to the vehicle management office where their registered permanent residence is located, and it can be increased to A2 after passing the examination. As for how long it will take, it depends on whether you successfully pass the exam. If it goes well, it will be completed in about 2-3 months.
First of all, ticket C cannot be directly upgraded to ticket A. If you want to upgrade and drive to ticket A, you must take the following steps:
1. C 1 add B 1: the driver has held the C 1 driver's license for three years, and the driver can't get full marks during the year.
Ii. B2 C 1 is added: the driver holds c 1 full driver's license 1 year, but the driver's score in that year is not full.
Iii. B 1 increase A 1: the driver has held B 1 for five years, and the driver's score in that year cannot be full. Fourthly, B2 is increased by A2: the driver has held B2 for 3 years, and the driver's points have not expired.
