A1A2D driver's license allows driving a wide range of vehicles, covering those permitted under A1, A2, and D licenses. The specific permitted vehicle types are as follows: A1 License Permitted Vehicles: The A1 license permits driving large buses with more than 20 passengers. Additionally, passenger vehicles with a body length exceeding 6 meters also require an A1 license. Other vehicle types permitted under 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). A2 License: The A2 license permits driving tractors, which can only be operated by drivers holding an A2 license. Drivers with an A1 license cannot operate tractors. Other vehicle types permitted under A2 license include: 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). D License: Permits driving ordinary three-wheeled motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h. It also covers vehicles permitted under E and F licenses. If a holder already has an A1 license but cannot drive vehicles permitted under an A2 license, they can apply to upgrade to an A2 license, provided they meet legal, regulatory, and age requirements. After passing the required tests, the permitted vehicle types on the license will be updated to "A1A2." If they further wish to add a D license, passing the relevant tests will update the license to "A1A2D." Holders of an A1A2D license must be between 26 and 50 years old. Obtaining an A1A2D license takes nine years from the age of 18: D license at 18, B2 upgrade at 21, A2 upgrade at 24, and A1 upgrade at 26, provided no 12-point penalty is incurred during this period. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," there are 16 categories of driver's licenses: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, P. The Ministry of Public Security has further subdivided licenses into 15 categories, with new licenses issued during annual inspections or renewals. C1 License: Permits driving small vehicles with up to 9 seats and a body length not exceeding 6 meters. Other permitted vehicle types include C2 (small automatic transmission cars), C3 (low-speed trucks), and C4 (three-wheeled vehicles). C2 License: This common license permits driving automatic transmission cars with up to 9 seats and a body length not exceeding 6 meters. Note that C2 license holders cannot drive manual transmission vehicles. B1 License: Permits driving medium-sized buses, defined as vehicles not exceeding 6 meters in length with a passenger capacity of 10 to 19. Other permitted vehicle types include C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery). B2 vehicles are not included. B2 License: Permits driving heavy or medium-sized trucks or large, heavy, or medium-sized specialized vehicles. Heavy and medium-sized trucks are primarily used for cargo transport.

A3 License: This license is specialized for city buses. Other permitted vehicle types include C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), and C4 (three-wheeled vehicles). A3 license holders cannot drive B1 or B2 vehicles, even though buses may resemble large passenger vehicles in size. The 16 categories of driver's licenses are classified based on the driving difficulty and safety requirements of different vehicle types. The classification expands on the existing A (large buses), B (large trucks), and C (small cars) categories, adding D, E, F, M, N, and P levels. Under the new regulations, first-time applicants cannot apply for an A1 (large bus) license. Eligible vehicle types for initial application include city buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, three-wheeled vehicles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Temporary residents can apply for C category licenses (small cars, small automatic transmission cars, low-speed trucks, three-wheeled vehicles) but not motorcycles. Holders of the newly added E license can drive ordinary two-wheeled motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h. F license holders can drive light motorcycles with an engine displacement ≤ 50ml or a maximum design speed ≤ 50km/h.
