Unrestricted NSW driver licence holders who reach or exceed 13 demerit points are sent a Notice of Suspension, or are refused a licence if they apply to renew one. Professional drivers have a demerit points threshold of 14 points, provided they meet the criteria.
If you can demonstrate that you meet the professional driver criteria, any suspension (or refusal) that was applied based on 13 demerit points exactly will be withdrawn. If you subsequently reach or exceed 14 demerit points however, you will be subject to suspension or refusal as per other unrestricted licence holders.
