Can a B2 Driver's License Operate a Semi-Trailer?

A B2 driver's license does not permit the operation of a semi-trailer. A B2 license only allows driving heavy and large trucks, as well as vehicles falling under the C1-C4 and M categories. Below is more information about semi-trailers: Definition of a Semi-Trailer: A semi-trailer is a trailer with its axles positioned behind the vehicle's center of gravity (when the load is evenly distributed) and equipped with a coupling device that transmits both horizontal and vertical forces to the tractor. Semi-trailers are typically three-axle vehicles and come in various types, such as 11-meter cargo barrier trailers, 13-meter cargo barrier trailers, low-bed semi-trailers, among others. They are heavy-duty transport vehicles connected to the tractor via a kingpin. Precautions for Driving a Semi-Trailer: While driving, avoid making large steering wheel movements due to the vehicle's long body, as this can lead to rollovers. Extra caution is needed when turning; always allow ample space to avoid the trailer's tail swinging out, which could potentially hit someone.
I also wondered about this when I just got my B2 license. Simply put, **a B2 license does not allow driving semi-trailer trucks**, but it does permit operating heavy-duty trucks. Semi-trailers fall under the category of tractor trailers, which require an A2 license. I have a friend in transportation who initially drove container trucks with a B2 license but later upgraded to an A2 specifically to handle semi-trailer jobs. Driving a semi-trailer isn't just about controlling the tractor unit; you also have to manage the trailer's movement, which is significantly more technically demanding. If caught driving a semi-trailer with a B2 license, it's considered unlicensed driving, resulting in a 2000-yuan fine and possibly even detention. If you're serious about driving semi-trailers, the safest route is to properly upgrade your license at a driving school.
Last time chatting with some veteran drivers at the logistics park, I learned that B2 and A2 licenses required for semi-trailers are completely different. The B2 driving license clearly states its permitted vehicle types: heavy/medium trucks, or large/heavy/medium special purpose vehicles. Semi-trailers? Not on the list at all! For those semi-trailers towing containers or tankers with a fifth wheel coupling on the tractor unit, you must have the pink-covered A2 license. With increasingly strict traffic regulations and frequent highway checkpoint inspections by traffic police, it's not worth taking the risk. If you really want to drive semi-trailers, getting a tractor qualification certificate first is the right approach.
I've reviewed the latest 'Regulations on the Application for Motor Vehicle Driving Licenses.' A B2 license allows driving trucks with a total mass exceeding 4.5 tons, but semi-trailer tractors require a separate A2 license. The key difference lies in the vehicle structure—the semi-trailer tractor has a specialized fifth-wheel coupling, which is completely different from the integrated structure of regular trucks. To upgrade to an A2 license, you must also meet conditions such as holding a B license for at least three years and having no record of full-point violations. My cousin spent four months upgrading from B2 to A2, practicing reversing and shifting every day. Maneuvering a trailer is far more complex than handling a single vehicle.
