You can take the test after holding a C1 driver's license for one year. If you pass the test, the vehicle management office will issue a new-level driver's license within 7 working days. The following are the conditions for upgrading from C1 to B2: To add a new permitted vehicle type to an existing motor vehicle driver's license, you must have held the (C1) permitted vehicle type driver's license for more than three years, and within the current scoring cycle to the most recent scoring cycle before applying for the new permitted vehicle type, there must be no record of accumulating 12 penalty points. Only then will the vehicle management office approve the application for the new permitted vehicle type. C1 is one of the codes for permitted vehicle types in a driver's license. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), C1 refers to a driver's license that permits driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light and micro special-purpose vehicles. It also allows driving the permitted vehicle types of C2, C3, and C4. B2 driver's license permits driving heavy and medium-duty cargo vehicles or large, heavy, and medium-duty special-purpose vehicles. Heavy and medium-duty cargo vehicles are mostly trucks, such as the large dump trucks commonly seen on roads, which belong to heavy-duty trucks. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water sprinklers, concrete mixer trucks, fire trucks, etc. Article 14 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that for first-time applicants of a motor vehicle driver's license, the permitted vehicle types that can be applied for include city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, small automatic transmission passenger vehicles for the disabled, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and tramcars. For those who already hold a motor vehicle driver's license and wish to add permitted vehicle types, the additional permitted vehicle types that can be applied for include large passenger vehicles, tractor trucks, city buses, medium-sized passenger vehicles, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and tramcars. Article 15 states that for those who already hold a motor vehicle driver's license and apply to add permitted vehicle types, there must be no record of accumulating 12 penalty points in the current scoring cycle and the most recent scoring cycle before the application. This applies to applications to add medium-sized passenger vehicles, tractor trucks, and large passenger vehicles as permitted vehicle types.
