I had to take a number last time I went a couple of years ago near Houston, TX. They sent text alerts to my phone. My first one was "your wait time is estimated at 3 hours, 15 minutes". I think it ended up being about 2 hours, 50 minutes. All I was doing was taking the eye test and having my picture taken. My procedures took about 8 minutes or less.
I don’t know if it’s ok in Texas, but I would drive to a rural county DMV and get my license renewed there................
