You do not have any available appointment times before my license expires. What can I do?
If there are no appointment times before your expiration date, you will need to go to an office that accepts walk-ins.
You can go to any driver license office, regardless of the county. Look at the list of offices -- if it says By Appointment Only, you know that you cannot walk in to that office. Otherwise, you can walk into any office that is convenient for you.
