[MacWilliam]

The difference between additional driving license and direct examination lies in the different applicable situations and the requirements for obtaining a driver's license. The following are detailed explanations: Different applicable situations: The situations applicable to additional driving license and direct examination are not the same. For example, if a driver already has a driving license and wants to expand the scope of permitted vehicle types, they can only do so through additional driving license. However, if they do not have a driver's license, they can choose direct examination based on the application requirements. For instance, if someone already holds a C license and wants to drive a motorcycle, they must obtain an additional D license. But if they originally do not have a driver's license, they can directly obtain a D license. Different requirements for obtaining a driver's license: Certain high-level driver's licenses, such as the A1 license, explicitly stipulate that they cannot be obtained through direct examination and can only be obtained through additional driving license.
