Adding a driving license refers to the process where, after obtaining a driving qualification certificate for one year, a driver takes and passes the examination for another driving qualification certificate. For example, a driver who already holds a C1 license can obtain a B1 driving qualification certificate after one year, thereby gaining the qualification for an additional license. Below are relevant details: 1. Applying for an additional license requires passing the corresponding motor vehicle driving qualification examination. 2. According to Article 15 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," if a person already holds a motor vehicle driving license and applies to add a permitted driving model, they must not have accumulated 12 penalty points in the current scoring cycle and the most recent scoring cycle before the application. 3. Applications to add medium-sized buses, tractors, or large buses as permitted driving models must also meet the following requirements: (1) To apply for a medium-sized bus permit, the applicant must have held a city bus, large truck, small car, small automatic transmission car, low-speed cargo truck, or three-wheeled car driving qualification for at least three years and must not have accumulated 12 penalty points in the three most recent consecutive scoring cycles before the application. (2) To apply for a tractor permit, the applicant must have held a medium-sized bus or large truck driving qualification for at least three years or a large bus driving qualification for at least one year and must not have accumulated 12 penalty points in the three most recent consecutive scoring cycles before the application. (3) To apply for a large bus permit, the applicant must have held a city bus, medium-sized bus, or large truck driving qualification for at least five years or a tractor driving qualification for at least two years and must not have accumulated 12 penalty points in the five most recent consecutive scoring cycles before the application. 4. Full-time students receiving driving vocational education who have obtained a small car driving qualification at school and have not accumulated 12 penalty points in the current scoring cycle and the most recent scoring cycle before the application can apply to add large bus or tractor permits. 5. According to Article 74 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the first 12 months after a motor vehicle driver initially applies for a driving license or adds a permitted driving model is the probationary period. 6. Drivers who newly obtain a large bus, tractor, city bus, medium-sized bus, or large truck license must, within 30 days after the probationary period ends, take an examination on road traffic safety laws and regulations, safe and civilized driving, emergency handling, and other knowledge, and receive no less than half an hour of traffic accident case warning education. During the probationary period, a motor vehicle must display a uniform-style probationary sign at the rear of the vehicle.
