Yes, an exam is required. The following are the conditions for upgrading from C1 to B2: You must have held a C1 driver's license for small cars for at least 3 years, with no full-point records in the last three consecutive scoring cycles, be between 20 and 50 years old, have not been involved in a traffic accident resulting in death with equal or greater responsibility, have not driven under the influence of alcohol, 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 micro passenger vehicles, light and micro cargo vehicles, and light and micro special-purpose vehicles, and also allows driving vehicles under C2, C3, and C4 license types. A B2 license allows driving heavy and medium-duty trucks or large, heavy, and medium special-purpose vehicles. Heavy and medium-duty trucks 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 special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water trucks, 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, 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 vehicles for the disabled, 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 driver's license and wish to add additional vehicle types must have no full-point records in the current scoring cycle and the most recent scoring cycle before application. For adding medium passenger vehicles, tractors, or large passenger vehicles, the following additional conditions apply: For adding medium passenger vehicles, the applicant must have held a city bus, large truck, small car, small automatic transmission car, low-speed cargo vehicle, or three-wheeled car license for at least three years, with no full-point records in the last three consecutive scoring cycles.
