How long after downgrading from B2 to C1M can one apply for a license upgrade?

[AdamMarie]

After downgrading from B2 to C1M, you can apply to upgrade back to B2 one year after completing the downgrade license exchange process. 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 where you bore equal or greater responsibility. Below is the classification of driver's licenses: 1. A1 license: Permits driving large buses and A3, B1, B2, C1, C2, C3, C4, M. 2. A2 license: Permits driving tractor vehicles and B1, B2, C1, C2, C3, C4, M. 3. A3 license: Permits driving city buses and C1, C2, C3, C4. 4. B1 license: Permits driving medium-sized buses and C1, C2, C3, C4, M (medium-sized buses refer to passenger vehicles with fewer than 19 seats, such as minibuses and vans).
