It's not complicated. The conditions for upgrading from C1 to B2 are as follows: You must have held a C1 driver's license for small cars for at least 3 years, with no record of full penalty points in the last three consecutive scoring cycles. You must be between 20 and 50 years old, have not been involved in a traffic accident resulting in death with equal or greater responsibility, have no record of drunk driving, and have not had your driver's license revoked or canceled within the last ten years. C1 is a code for a type of 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 mini passenger cars, light and mini cargo trucks, as well as light and mini special-purpose vehicles. It also allows driving vehicles under the C2, C3, and C4 categories. A B2 driver's license permits driving heavy and medium-duty trucks or large, heavy, and medium-duty special-purpose vehicles. Heavy and medium-duty trucks are mainly trucks, such as the large dump trucks commonly seen on roads. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with specialized equipment or tools, such as water trucks, concrete mixer trucks, and fire trucks. Article 14 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that first-time applicants for a motor vehicle driver's license can apply for licenses covering urban buses, large trucks, small cars, small automatic transmission cars, low-speed cargo trucks, three-wheeled cars, small automatic transmission passenger cars for disabled persons, 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 additional license categories, the following can be applied for: large passenger vehicles, tractors, urban buses, medium-sized passenger vehicles, large trucks, small cars, small automatic transmission cars, low-speed cargo trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Article 15 states that those who already hold a motor vehicle driver's license and wish to add additional license categories must have no record of 12 penalty points in the current scoring cycle and the most recent scoring cycle before application. For those applying to add medium-sized passenger vehicles, tractors, or large passenger vehicles, the following additional conditions apply: To add a medium-sized passenger vehicle license, the applicant must have held a license for urban buses, large trucks, small cars, small automatic transmission cars, low-speed cargo trucks, or three-wheeled cars for at least three years, with no record of 12 penalty points in the last three consecutive scoring cycles before application. To add a tractor license, the applicant must have held a license for medium-sized passenger vehicles or large trucks for at least three years, or a large passenger vehicle license for at least one year, with no record of 12 penalty points in the last three consecutive scoring cycles before application. To add a large passenger vehicle license, the applicant must have held a license for urban buses, medium-sized passenger vehicles, or large trucks for at least five years, or a tractor license for at least two years, with no record of 12 penalty points in the last five consecutive scoring cycles before application. Students currently enrolled in full-time driving vocational education who have obtained a small car license while in school and have no record of 12 penalty points in the current and most recent scoring cycle before application can apply to add large passenger vehicle or tractor licenses.
