Hi Badrul Tan, thank you for your question. If you accumulate more than 13 demerit points, it is possible that your Class 2B, 2A, and 3 licenses may also be revoked. Typically, accumulating a certain number of demerit points within a specific timeframe can lead to the suspension or revocation of all your driving licenses. It is best to check with the relevant traffic authorities for the specific rules and regulations that apply to your situation.
