Our County Tax Collector has had an inquiry from someone who wants to post cash in lieu of buying car insurance as per Trans. Code 601.123. Anyone out there ever dealt with this? Specifically, does anyone have a form for the certificate described in the Code?

Try contacting DPS' section, Driver Improvement, for information regarding the process. They may also be able to provide you with, or at least steer you in the direction of, the right form(s). The main number is 512-424-2000. Be prepared to wade through the menu!
