What are the requirements for upgrading from A1 to A2?

[OErin]

A1 to A2 upgrade requires that the A1 driver's license must have completed a one-year probationary period, and there must be no record of accumulating 12 penalty points during the A1 license period. Introduction to A2 Driver's License: The A2 driver's license permits the operation of tractor-trailers. Holders of a valid A2 license issued by the Chinese public security traffic management authorities can drive heavy and medium-sized full trailers and semi-trailers, as well as vehicles permitted under B1, B2, C1, C2, C3, C4, and M licenses. Introduction to A1 Driver's License: The A1 driver's license permits the operation of buses that can carry more than 20 passengers, commonly seen on the road, as well as passenger vehicles with a body length exceeding 6 meters. Other vehicle types permitted under the A1 license include: A3 (city buses), B1 (medium-sized buses), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery). Only the A2 license permits the operation of full trailers and semi-trailers, which the A1 license does not cover.
