What are the new regulations for upgrading from a C1 to a B2 driver's license?

[McKennedy]

It's not complicated. The conditions for upgrading from a C1 to a B2 license are as follows: Hold a C1 driver's license for small cars for at least 3 years, with no full demerit point records in the last three consecutive scoring cycles, aged between 20 and 50 years old, no record of causing a fatal traffic accident with equal or greater responsibility, no record of drunk driving, and no revocation or cancellation of the driver's license 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 refers to a license that 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 under the C2, C3, and C4 categories. A B2 license permits driving heavy and medium-duty trucks or large, heavy, and medium special-purpose vehicles. Heavy and medium-duty trucks are mainly trucks, such as the large dump trucks commonly seen on roads, which fall under the category of heavy trucks. Large, heavy, and medium special-purpose vehicles refer to vehicles equipped with specialized equipment 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 city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, small automatic transmission cars 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 additional permitted vehicle types, the additional types include large passenger vehicles, tractors, city 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 wish to add additional permitted vehicle types, they must not have a record of accumulating 12 demerit points in the current scoring cycle and the most recent scoring cycle before the application. For applications to add medium-sized passenger vehicles, tractors, or large passenger vehicles, the following additional conditions must be met: For adding medium-sized passenger vehicles, the applicant must have held a license for city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, or three-wheeled cars for at least three years, with no record of accumulating 12 demerit points in the last three consecutive scoring cycles before the application. For adding tractors, the applicant must have held a license for medium-sized passenger vehicles or large trucks for at least three years, or a license for large passenger vehicles for at least one year, with no record of accumulating 12 demerit points in the last three consecutive scoring cycles before the application. For adding large passenger vehicles, the applicant must have held a license for city buses, medium-sized passenger vehicles, or large trucks for at least five years, or a license for tractors for at least two years, with no record of accumulating 12 demerit points in the last five consecutive scoring cycles before the application. Full-time students receiving driving vocational education who have obtained a license for small cars while in school and have no record of accumulating 12 demerit points in the current scoring cycle and the most recent scoring cycle before the application may apply to add large passenger vehicles or tractors.
