What is the process for adding a D license to a C1 license?

[EvanLynn]

C1 to D license upgrade process is as follows: If you already hold a motor vehicle driver's license and wish to add an additional vehicle class, you must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle prior to application. If the above requirements are met, you can submit an application to add a D or E vehicle class at the location where your C1 license was issued. To upgrade your license, you must have a local household registration in the area where you wish to upgrade, and the license issuing authority must also be local. If you do not have local household registration or a local license relationship, the application will not be processed, and you will need to transfer the relationship. What is a C1 driver's license: A C1 driver's license is a type of motor vehicle driver's license classification. The permitted driving scope of a C1 license includes small and mini passenger vehicles, light and mini cargo vehicles; light, small, and mini special purpose vehicles; and small passenger vehicles with seating capacity of 9 or fewer people.
