If you would like apply for a Texas ID card for identification purposes, or a Driver License in order to drive in Texas, you will need to go to the Department of Public Safety.
The Department of Public Safety in San Marcos is located off South I-35 between the exit to Hopkins/Hwy 80 and Aquarena Springs. There is a CARTS city bus route that will take you to the DPS, ask the International Office for a free bus routes map or download it below.
