The requirements for upgrading a B1 driver's license to B2 are: 1. After the probation period of the B1 driver's license ends; 2. The holder of the B1 driver's license must not have a record of 12 penalty points in the current scoring cycle and the previous scoring cycle before application, and must not have any circumstances that prohibit applying for a large truck license; 3. Must participate in driving school training and pass the subject one, two, and three exams at the vehicle management office. The permitted vehicle types for a B1 license are medium-sized buses, and other permitted vehicle types include small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, and wheeled self-propelled machinery. The permitted vehicle types for a B1 license do not include B2. If a driver holding a B1 license wants to drive large trucks, they can upgrade their license to a B1B2 license.
