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 license categories. The B2 license permits driving heavy and medium-duty cargo vehicles or large, heavy, and medium-duty special-purpose vehicles. Heavy and medium-duty cargo vehicles are mostly trucks, such as the large dump trucks commonly seen on roads, which fall under the category of heavy trucks. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with specialized equipment or devices, 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 passenger cars for the disabled, 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, there should be no record of accumulating 12 points in the current scoring cycle and the most recent scoring cycle before the application. For applications to add medium passenger vehicles, tractors, or large passenger vehicles, the following additional conditions must be met: For adding medium 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 more than three years, with no record of accumulating 12 points in the last three consecutive scoring cycles before the application.
