Is A2 or A3 bigger?

[McJasper]

A2 and A3 cannot be directly compared as they allow driving different types of vehicles. A2: The A2 driver's license permits driving articulated vehicles (commonly known as heavy truck heads), large trucks, and medium-sized buses (minibuses). A3: The A3 driver's license is for urban buses and ordinary cars that can be driven with a C1 license. Differences: A2 includes articulated vehicles and vehicles permitted by B1, B2, and M licenses, while A3 includes urban buses and vehicles permitted by C1 licenses. Therefore, they are different, and if needed, both must be obtained. Even an A1 license does not include articulated vehicles under A2. A2 is for articulated vehicles, medium-sized buses, and small cars. A3 is for urban buses and small cars. A3 is larger in the sense that it takes 8 years of additional training to drive buses, and people with A3 licenses usually also have A2.
