If you are moved from out of state and have an appt to get TX lic, can you still drive after 90days window. Is there an extension on that which makes Out of state lic still valid.

Yes. Just holding an appointment for 90days or more, let's you drive with your out of state license, since it is something that we don't have any kind of control. Now, if the license is already expired, holding an appointment is not an extension of it, but it is proof that you're on top of your interest of obtaining a TX DL. And by being already experired, once your appointment comes up, dependind on the time frame of the expiration date of your DL and the appointment date, you might need to take a driving exam and/or test again. Texas DPS driving test is perform by a Texas State Trooper Officer.

Yes. I believe there is.
