If I was you,don't use the website just go. I don't know if you live in Grand prairie but..if you do that is the one be there before 8:00 because it's crowded and they will give you a appointment.
I'm thinking that it's www Texas department of public safety I think that would get you in if not you can always contact them by phone which Google could give you the phone number address and the nearest one to you
