Driving after consuming alcohol or drugs can lead to serious criminal charges in Texas. However, many drivers are confused about the difference between driving under the influence (DUI) and driving while intoxicated (DWI), particularly because these terms are used differently across the United States.
Under Texas DWI laws, driving while intoxicated generally involves operating a motor vehicle in a public place while legally intoxicated. Texas also has a separate DUI offense primarily applicable to drivers under 21 who have consumed alcohol.
Understanding the differences, blood alcohol concentration (BAC) limits, potential penalties, and license consequences can help drivers recognize their legal rights and responsibilities.
What Is the Difference Between DUI and DWI in Texas?
In Texas, DWI generally applies to intoxicated drivers, while the separate DUI offense applies to minors who operate a motor vehicle or watercraft with a detectable amount of alcohol in their system.
Under Texas Penal Code § 49.04, a person commits DWI by operating a motor vehicle in a public place while intoxicated.
Texas Alcoholic Beverage Code § 106.041 establishes the separate DUI offense for individuals younger than 21.
Unlike adult DWI, underage DUI does not require proof that the driver’s BAC reached 0.08%.
What Is the Legal BAC Limit Under Texas DWI Laws?
The general BAC threshold for intoxication in Texas is 0.08%, although a driver may be charged with DWI below that level if alcohol or drugs impair normal mental or physical faculties.
Texas Penal Code § 49.01 defines intoxication using either a qualifying alcohol concentration or loss of normal faculties.
Important distinctions include:
- Drivers aged 21 and older: A BAC of 0.08% meets the statutory alcohol concentration definition of intoxication.
- Commercial drivers: A 0.04% BAC threshold can trigger separate commercial driving consequences.
- Drivers younger than 21: Texas prohibits operating a motor vehicle with any detectable amount of alcohol, subject to statutory exceptions.
A BAC result is not the only evidence prosecutors may use in a DWI case.
What Are the Penalties for a First DWI in Texas?
A first DWI conviction is generally a Class B misdemeanor, carrying up to 180 days in jail and a fine of up to $2,000.
Texas law also generally requires a minimum jail term of 72 hours for this offense.
When an open container of alcohol is present in the driver’s immediate possession, additional minimum confinement requirements may apply.
A BAC of 0.15% or higher at the time of analysis can elevate a first DWI offense to a Class A misdemeanor.
Additional consequences may include license suspension, court costs, and ignition interlock requirements in qualifying cases.
What Happens After a Second or Third DWI Conviction?
Repeat DWI convictions generally carry more severe penalties, including longer jail sentences, higher fines, and potential felony charges.
Under Texas Penal Code § 49.09:
- Second DWI: Generally a Class A misdemeanor, with a statutory minimum of 30 days in jail and a potential sentence of up to one year.
- Third DWI: Generally a third-degree felony when the required prior convictions are established, punishable by two to ten years in prison.
- DWI with a child passenger: Operating while intoxicated with a passenger younger than 15 is generally a state jail felony.
Other aggravating circumstances, including serious injuries or fatalities, can result in additional felony charges.

Can You Lose Your Driver’s License After a Texas DWI Arrest?
Yes. Texas drivers may face administrative license suspension even before their criminal DWI case is resolved.
The Administrative License Revocation (ALR) program addresses qualifying breath or blood test failures and refusals.
Drivers generally have 15 days after receiving an ALR suspension notice to request a hearing. If no hearing is requested, the suspension generally begins on the 40th day after notice.
Criminal court proceedings and administrative license proceedings are separate processes.

What Are the Penalties for Underage DUI in Texas?
A first underage DUI offense is generally a Class C misdemeanor and may result in a fine, community service, alcohol education requirements, and license consequences.
Under Texas Alcoholic Beverage Code § 106.041, the offense involves a driver younger than 21 operating with a detectable amount of alcohol.
Repeat violations may result in more serious penalties. A minor may also face a DWI charge if the evidence establishes intoxication under the Penal Code.
