You can apply for an upgrade if there is no demerit record within one year. According to the Regulations on the Application and Use of Motor Vehicle Driving Licenses, Article 14: If you already hold a motor vehicle driving license and apply to add a permitted driving model, you must not have a record of 12 demerit points in this scoring cycle and the most recent scoring cycle before the application. Below is relevant information: 1. Situations where an upgrade is not allowed: Being held equally or more responsible for a traffic accident resulting in death; Driving under the influence of alcohol leading to license revocation or if the motor vehicle driving license has not been held for 10 years. 2. Vehicles that can be driven with a B2 license: A B2 license permits driving heavy-duty, medium-duty trucks or large, heavy, medium-sized special-purpose vehicles. Heavy-duty and medium-duty trucks are mostly trucks, such as the large trucks commonly seen on the road carrying construction waste, which belong to the heavy-duty truck category. Large, heavy, medium-sized special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water sprinklers, concrete mixers, fire trucks, etc.
