Can a C2 license be upgraded to C1?

[SanAngela]

You can upgrade from a C2 driver's license to a C1, provided that: You need to hold a C2 driver's license, ID card, and a health certificate, then apply at the vehicle management office that issued the C2 license. You must undergo study and tests, and upon passing, you can exchange for a C1 driver's license. If you already hold a motor vehicle driver's license and apply to add a permitted vehicle type, you must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle before the application. C1 driver's license test: The test subjects include traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving common sense—four items in total. Passing standards: Traffic regulations and related knowledge (Subject 1)—written test, full score is 100, 90 or above is passing. Field driving (Subject 2)—on-site, actual vehicle.
