First DWI Offenses in Houston, TX

You Need an Aggressive Houston DWI Attorney

Even a first driving while intoxicated (DWI) offense can have serious consequences. In Houston, a driver convicted of a first DWI may face:

  • Fine up to $2,000
  • 3 to 180 days in jail
  • License suspension for 1 year

A surcharge of $1,000 per year may also be assessed by the Texas Department of Public Safety (DPS), or $2,000 per year if your blood alcohol concentration (BAC) was .16 or greater. And if your BAC is greater than a 0.15, the case may be enhanced to a Class A Misdemeanor, which doubles the range of punishment and fines.

If you’ve been arrested for DWI, an aggressive defense is your only option if you want to avoid a conviction and significant penalties. Thiessen Law Firm is committed to fighting for drivers across the greater Houston area, and we have a track record of success in this complex and challenging arena.

With our understanding of DWI law, breath and blood testing, field sobriety tests, local courts, and case law, we know exactly how to approach a case with each client’s best interests in mind. We will not settle for anything less than the best result possible.

For more information on our services and how our Houston DWI attorneys can help you, call (713) 999-3959. We are available 24/7 and offer a free consultation to help you get started.

You only have 15 days to
save your license!
