A C1 license cannot be directly upgraded to an A2. If you already have a C1 driver's license, the fastest way to obtain an A2 license is to upgrade to a B1 or B2 license after holding the C1 license for one year. After obtaining the B1 or B2 license, you must have three years of professional driving experience before you can apply for the A2 license. Therefore, upgrading from a C1 to an A2 license takes at least four years. Another method is to directly obtain a B2 license. After holding the B2 license for three years, you can also upgrade to an A2 license. This method is faster but does not involve upgrading directly from a C1 license. According to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses' (Ministry of Public Security Order No. 123) of the People's Republic of China, the following conditions must be met for upgrading a driver's license: Article 14: If you already hold a motor vehicle driver's license and wish to apply for an additional permitted vehicle type, you must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle before the application. For applying to add medium-sized buses, tractors, or large buses to the permitted vehicle types, the following additional regulations apply: To apply for adding medium-sized buses to the permitted vehicle types, you must have held a license for urban buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, or three-wheeled cars for at least three years and must not have accumulated 12 penalty points in the three most recent consecutive scoring cycles before the application. To apply for adding tractors to the permitted vehicle types, you must have held a license for medium-sized buses or large trucks for at least three years, or have held a license for large buses for at least one year, and must not have accumulated 12 penalty points in the three most recent consecutive scoring cycles before the application. To apply for adding large buses to the permitted vehicle types, you must have held a license for medium-sized buses, urban buses, or large trucks for at least five years, or have held a license for tractors for at least two years, and must not have accumulated 12 penalty points in the five most recent consecutive scoring cycles before the application. In temporary residence areas, you can apply to add small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or light motorcycles to the permitted vehicle types.
