What are the requirements for upgrading from a C3 to a C1 driver's license?

[Francisco]

C3 license holders can upgrade to a C1 license after one year. The conditions for upgrading from a C3 to a C1 license are: 1. You must have held a C3 license for more than one year, and there should be no record of accumulating 12 penalty points in the current scoring cycle or the most recent scoring cycle before applying. 2. You must apply for the upgrade at the vehicle management office in the jurisdiction where the C3 license was originally issued; it cannot be processed elsewhere. According to Article 15 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses,' if you already hold a motor vehicle driver's license and apply to add a permitted vehicle type, there should be no record of accumulating 12 penalty points in the current scoring cycle or the most recent scoring cycle before applying. A C1 driver's license is one of the codes for motor vehicle driver's licenses. The scope of vehicles permitted to be driven with a C1 license includes small and micro passenger vehicles, light and micro cargo vehicles, light, small, and micro special-purpose vehicles, and small passenger vehicles with a seating capacity of 9 or fewer people.
