Can a C1 driver's license be directly upgraded to a B1?

[ArielLynn]

C1 can be directly upgraded to B1. Below are the relevant details about upgrading from C1 to B1: 1. Minimum three years: You must have held a C1 license for at least three years before upgrading to B1. 2. Age and other requirements: Applicants must be between 21 and 50 years old, with a minimum height of 155 cm, and have uncorrected or corrected visual acuity reaching 5.0 on the logarithmic visual acuity chart. The upgrade can only be processed at the location of your household registration. Additionally, there should be no record of full penalty points in the last two scoring cycles, no history of drunk driving, and no record of being primarily or fully responsible in a fatal accident.
