Do I have to wait one year to upgrade after downgrading to B2?

[VanLorenzo]

You can apply to upgrade to B2 after one year. Here are the relevant requirements: Conditions: You must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle before applying, and you must not have been involved in any traffic accident resulting in death with equal or greater responsibility. Article 78 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that after applying for a downgrade in driver's license class, if you wish to apply for an upgrade to a higher driving category, you must meet the scoring requirements in the current cycle and must not have accumulated 12 penalty points in the most recent scoring cycle before applying. Additionally, you must not have been involved in any fatal traffic accident where you bore equal or greater responsibility. B2 License: A B2 license allows you to drive heavy-duty, medium-duty trucks or large, heavy, and medium-sized specialized operation vehicles. Heavy-duty and medium-duty trucks are mainly trucks, and the large trucks commonly seen on the road fall under the category of heavy-duty trucks.
