The Texas State Legislature in its 85th Session passed a law to take effect in September 2017. Any person who has been convicted of DWI (1st time) where there were no accidents or injuries will be permitted to file for a non-disclosure. There is a 2 year waiting period and the BAC must have been less than .15.
A non-disclosure is a petition that is filed with the Court which permits a person to seal records (from the Public) of an arrest and accompanying Court documents. The Federal government will still be able to see the records.
