Presumptuous?
You can't go telling the department of transportation that you want them to suspend his license and expect them to jump on your say so. You've already posted all the information you need to know - DHFS can report him and request the suspension, or a judge can order it. You can petition the court for enforcement of your order, and a judge would decide what is appropriate. If DHFS moves too slow for you, you're not the only one who thinks that. You can adopt more patience or try to get them to move faster (good luck).
But you need to get a reality check about something else as well: Dad can get a permit and still have many of his driving privileges anyway. Might not be that motivational.
