[NicoleAnn]

A B2 license holder can drive a tractor head without a trailer. Without a trailer, it is just a single vehicle, which a B2 license fully permits. Below is an introduction to the types of vehicles a B2 license holder can drive: Type: Medium and heavy-duty trucks or specialized operation vehicles, also allowing the driving of small cars, small automatic transmission cars, low-speed trucks, three-wheeled vehicles, and wheeled self-propelled machinery. Note: A B2 license holder in the probationary period must be accompanied by a driver who has held a corresponding or higher-level driving license for more than three years when driving on the highway. The accompanying driver should sit in the front passenger seat to guide the probationary driver. Driving without an accompanying driver or with an unqualified accompanying driver will result in a fine.
