Is an exam required after one year of holding a C1 driver's license?

[StRylee]

C1 driver's license holders do not need to take an exam after one year. Article 22 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates that the validity period of a motor vehicle driver's license is six years. The first 12 months after a driver initially obtains a motor vehicle driver's license is the probationary period. During the probationary period, when driving a motor vehicle, a unified probationary sign should be affixed or hung at the rear of the vehicle. Drivers who newly obtain A1, A2, A3, B1, or B2 licenses must take an exam on road traffic safety laws and regulations, traffic safety and civilized driving, emergency handling, and other knowledge within 30 days after the probationary period ends. Permitted vehicle types for C1 driver's license: The scope of vehicles permitted for a C1 driver's license includes small and mini passenger vehicles, as well as light and mini cargo vehicles; light, small, and mini special-purpose vehicles; and small passenger vehicles with a seating capacity of nine or fewer people.
