Texas statute TRC CH. 601.340 provides a Safety Responsibility Law or Evidence of Financial Responsibility Law, for individuals whose driver license or privilege has been suspended or revoked.
In order to reinstate driving privileges, individuals are required to file and maintain insurance in the form of an SR-22, original pink copy, with the Department. SR-22 insurance is mandatory for a period of two (2) years from date of conviction.
A reinstatement fee is also required with the SR-22. Within the two-year time frame, if the Department receives notice from the insurance company that insurance coverage has been canceled, suspension action will be taken.
