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 license for at least one year. Additionally, there should be no record of accumulating 12 penalty points from the current scoring cycle to the most recent scoring cycle before applying for the new permitted vehicle type. Only then will the vehicle management office approve the application. C1 is a code for a permitted vehicle type in the 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 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 vehicles permitted under C2, C3, and C4. A 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 fall under the category of heavy trucks. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with specialized devices or tools, such as water sprinklers, concrete mixers, 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 include urban 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 trams. For those who already hold a motor vehicle driver's license and wish to add a permitted vehicle type, the additional permitted vehicle types include large passenger vehicles, tractor-trailers, urban 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 trams. Article 15 states that for those who already hold a motor vehicle driver's license and apply to add a permitted vehicle type, there should 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 for adding medium-sized passenger vehicles, tractor-trailers, and large passenger vehicles. The B2 driver's license test consists of four subjects: Subject 1 covers road traffic laws and regulations related to driving motor vehicles, including road traffic rules, traffic violations, traffic signals, and accident handling. Subject 2 involves practical operations for large passenger vehicles, urban buses, tractor-trailers, etc., such as pile tests, side parking, hill starts, and driving over single-side bridges. Subject 3 includes test drive preparations, starting, driving straight, lane changes, and gear shifting operations for large passenger vehicles, urban buses, tractor-trailers, and medium-sized passenger vehicles. Subject 4 covers the operational requirements for safe and civilized driving, knowledge of safe driving in extreme weather and complex road conditions, and handling procedures in case of accidents.
