What does upgrading to a C1 driver's license mean?

[SanColeman]

Upgrading to a C1 driver's license refers to the additional licensing process after already obtaining a motor vehicle driver's license, specifically adding the C1 permitted vehicle type after acquiring a driver's license of another class. Conditions for upgrading from a C1 to a B2 driver's license: Age between 20 and 60 years old; height not less than 155cm; holding a C1 driver's license for at least 1 year; no record of accumulating 12 penalty points in the current scoring cycle or the most recent one before application; visual acuity must meet or exceed 5.0 on the logarithmic visual acuity chart; no record of drunk driving or being primarily responsible for a traffic accident causing casualties while holding the C1 license. Specific process for applying for a B2 driver's license: Apply to the vehicle management office for upgrading to a B2 license; complete the application form, submit ID card and physical examination report, and provide the original motor vehicle driver's license; attend theoretical and practical exams as scheduled; the new class of driver's license will be issued by the vehicle management office within 7 working days after passing the exams.
