You drove home after a couple of drinks, and now a traffic stop has turned into something you did not see coming: charges, court dates, and a record that could follow you for years. Or your teenager got pulled over, and no one in your household has any idea what that means under Texas law.
The questions about Texas DWI and DUI laws pile up fast, and the answers matter more than most people realize. At Walter J. Pink & Associates, we help people understand Texas drinking and driving laws, the penalties that may apply, and the options available to reduce or challenge the charges.
What Do Texas DWI and DUI Laws Actually Cover?
Texas law draws a sharp line between DWI and DUI, and the difference depends entirely on who is behind the wheel.
Texas DWI laws generally apply to adult drivers operating a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, or who have lost normal use of their mental or physical faculties due to alcohol, drugs, or another intoxicating substance.
Texas DUI laws, by contrast, apply specifically to drivers under 21. Under Texas’s “zero tolerance” approach for minors, any detectable amount of alcohol in the minor’s system may support a DUI charge, even if the driver shows no signs of impairment.
How Do Texas Drinking and Driving Laws Define Intoxication?
In Texas, when the State prosecutes adult drivers with intoxication, they can do so under one of two definitions. The first is a BAC of 0.08% or higher, measured by breath, blood, or urine test.
The second does not depend on a specific BAC result. If an officer observes that a driver has lost normal use of their mental or physical faculties, the State can pursue a DWI charge even when the test result falls below the legal limit.
That second definition gives law enforcement significant discretion, and it is one of the reasons DWI cases are more complicated than most people expect.
What Are the Penalties Under the Drink and Drive Laws in Texas?
Penalties climb steeply with each offense and with the circumstances surrounding the stop. Here is how Texas structures them:
- First DWI offense. A first offense is a Class B misdemeanor carrying a minimum of 72 hours in jail and up to 180 days, a fine of up to $2,000, and a driver’s license suspension of 90 days to one year.
- Second DWI offense. A second offense is a Class A misdemeanor, with a minimum of 30 days in jail, up to one year of confinement, and a fine of up to $4,000.
- Third DWI offense. A third offense is a third-degree felony, punishable by 2 to 10 years in prison and a fine of up to $10,000.
These penalties do not account for surcharges, ignition interlock requirements, or the costs associated with a conviction for employment and professional licensing.
What Happens When a Minor Faces a DUI Charge?
Texas applies drinking-and-driving laws differently for drivers under 21. A first DUI conviction is a Class C misdemeanor, which carries a fine of up to $500, 20 to 40 hours of community service, mandatory alcohol awareness education, and a 60-day license suspension.
A minor with two or more prior DUI convictions who is no longer considered a child under Texas law faces steeper consequences: fines between $500 and $2,000 and up to 180 days in jail. That third offense also removes eligibility for deferred disposition, which means no opportunity to avoid a conviction on the record.
What Other Factors Can Increase a DWI Charge?
Several circumstances push a DWI beyond its base classification. A BAC of 0.15% or higher on a first offense elevates the charge from a Class B to a Class A misdemeanor. Driving drunk with a passenger under 15 years old becomes a state jail felony under a separate provision.
If the driver causes serious bodily injury to another person, the charge becomes intoxication assault, a third-degree felony. A death resulting from drunk driving triggers intoxication manslaughter, a second-degree felony carrying 2 to 20 years in prison.
Why Texas DWI Laws Demand Experienced Representation
Understanding the law is the first step. Having a Houston DWI attorney who knows how to use it is what changes outcomes. Walter J. Pink & Associates has spent more than 50 years turning that knowledge into results, earning over 3,000 dismissals, logging more than 600 trials, and building a three-generation family practice that carries forward today.
In one intoxicated manslaughter case, the State asked for 15 years. The Pink attorneys worked to obtain a reduced sentence of 4 years, with parole eligibility after 2. Every case involves different facts and circumstances, but experienced representation can make a significant difference in how a case proceeds.
