What does a C1 or higher driver's license refer to?

[LaSteven]

C1 driver's license allows driving vehicles including (all models of C2, C3, C4) small and micro passenger vehicles, light and micro cargo vehicles, light, small, and micro special operation vehicles, etc. Here is additional information: 1. The C1 driver's license evolved from the C driver's license: In 2004, according to the "Road Traffic Safety Law" and its supporting policies, the old version of the C license (C driver's license) held by drivers was automatically converted to a B1 license in the vehicle management office's driver's license database. If unwilling to convert, one must apply to the vehicle management office to downgrade to the new C1 license. 2. The examination subjects include traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving common sense. During the examination, if one subject is failed, the following subjects will not proceed. Subjects two and three can be taken once with one retake opportunity. If the retake is still failed, the examination will be terminated.

I have taken these types of driver's licenses. C1 and above mainly refer to licenses that allow driving larger and more complex vehicles. Common ones include the C2 automatic transmission car license, but it is actually at the same level as C1. The truly higher-level licenses are the B-class licenses. For example, B1 allows driving medium-sized buses with fewer than 19 seats, which is required for school buses and minibuses; B2 is specifically for driving large trucks, like dump trucks at construction sites. Going further up, there are A-class licenses: A1 allows driving large buses, essential for long-distance passenger drivers; A2 is for driving semi-trailer tractors, commonly used in logistics; A3 is specialized for urban buses. The age requirements for obtaining these licenses are higher. For example, B2 requires being at least 20 years old, and A1 requires being 26 years or older.

Having worked in fleet management for ten years, I'm very familiar with licenses above C1. The B1 license is suitable for driving minibuses for business receptions, and our fleet dispatchers often arrange such tasks; B2 license holders drive heavy trucks for transportation; the A1 license for large buses is essential for long-distance routes, and drivers with this license earn higher wages; drivers operating semi-trailers must hold an A2 license, especially those hauling containers. These advanced licenses require additional annual medical check-ups, and traffic violations are dealt with more strictly. Although obtaining these licenses is costly, they offer significant career development opportunities.

For friends who want to upgrade their driver's license after obtaining a C1 license: Above C1 mainly refers to Class B (B1, B2) and Class A (A1, A2, A3). B1 allows you to drive yellow-plate medium-sized buses, while B2 corresponds to large trucks. A1 is for bus driver's licenses, A2 is specifically for semi-trailer tractors, and A3 is used by bus drivers. To take the test, you must be at least 20 years old, and the test items are much more complex than those for C1. After obtaining the license, you must also pay attention to stricter penalty point rules—accumulating 12 points in a year will result in an immediate downgrade.
