The requirements for upgrading from B2 to A1 license are: 1. For applicants seeking to upgrade to a large bus (A1) license, the original permitted driving models must be B1 or B2, with a driving experience of at least five years and no record of accumulating 12 penalty points within the past three years; 2. For applicants whose original permitted driving model is A2, the driving experience must be at least two years, with no record of accumulating 12 penalty points within the past year, and the age must be between 26 and 50 years old; 3. Applicants who have caused a fatal traffic accident and bear full responsibility are not eligible to apply for upgrading their permitted driving models. A driver's license, also known as a 'driving license,' is a document issued by the government transportation department to individuals who qualify to drive, usually in the form of a card. To obtain a driver's license, one must meet the minimum age requirement and pass a driving test.
