What vehicles can a Class B license drive?

[VanFinley]

A Class B license allows driving the following vehicles: 1. For B1, the permitted vehicle type is medium-sized passenger vehicles (including urban buses with a capacity of 10 to 19 people); 2. For B2, the permitted vehicle types are heavy and medium-duty trucks, such as large trucks carrying construction waste, and large, heavy, or medium-sized specialized operation vehicles, such as water sprinklers, concrete mixers, and fire trucks; 3. Both licenses also permit driving vehicles under Class C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery). A B1 driver's license cannot be directly applied for, but one can apply for an upgrade at their registered residence one year after obtaining a B2 license (provided there is no full-point record in the most recent scoring cycle before application). Alternatively, one can apply for an upgrade after holding a small car driving qualification for more than three years.
