DWI Penalties & Jail Time in Texas in 2026
Texas DWI Penalties: First, Second, and Third Offenses
Texas DWI penalties can become significantly more serious with prior convictions or certain aggravating circumstances. A first DWI is generally a Class B misdemeanor, punishable by 72 hours to 180 days in jail and a fine of up to $2,000. If an analysis shows an alcohol concentration of 0.15 or more at the time of testing, however, the offense is generally elevated to a Class A misdemeanor.
A second DWI is generally a Class A misdemeanor when the State proves one qualifying prior intoxication-related conviction. A third DWI is generally a third-degree felony when the State proves two qualifying prior convictions. A third-degree felony can carry 2 to 10 years in prison and a fine of up to $10,000.
When a DWI Can Become a Felony
Certain circumstances can increase the seriousness of a DWI even without multiple prior convictions. For example, Texas law makes DWI with a child passenger younger than 15 a state jail felony.
A DWI involving serious bodily injury or death can also result in separate felony charges. Intoxication assault generally involves serious bodily injury, while intoxication manslaughter involves a death. These offenses carry substantially more serious potential consequences than an ordinary DWI.
Texas law also provides enhanced penalties for certain intoxication offenses involving multiple victims and other specified circumstances. For example, legislation effective September 1, 2025, created a first-degree felony classification for intoxication manslaughter when the defendant causes the death of more than one person during the same criminal transaction.
In addition, a DWI committed in a school crossing zone during the applicable reduced-speed period can now be prosecuted as a state jail felony under legislation that took effect September 1, 2025.
DWI Law Changes Took Effect in 2025
Several significant intoxication-related changes were enacted during the Texas 89th Legislative Session in 2025 and became effective September 1, 2025.
One change concerns the execution of blood-specimen search warrants. Under amended Texas law, certain warrants for obtaining blood specimens in intoxication cases may be executed by a peace officer in an adjacent county, expanding the prior statutory authorization.
Other 2025 legislation addressed the preservation of toxicological evidence and increased penalties for certain intoxication offenses. These changes can be relevant when evaluating a DWI or other intoxication-related prosecution today.
Texas Has No Simple Seven-Year DWI Look-Back
Texas does not use a simple seven-year or ten-year look-back period for DWI enhancement. Prior qualifying intoxication-related convictions can potentially be used to enhance a later DWI even when the earlier case occurred many years ago.
That means a DWI conviction from 20 or 30 years ago may still matter in a new prosecution if it qualifies under Texas enhancement laws. The age of the prior case is therefore not necessarily enough to prevent the State from relying on it.
For a person facing a second or third DWI, an attorney should examine the actual records of the prior cases rather than simply counting how many years have passed. Whether a prior offense qualifies for enhancement can depend on the type of offense, the disposition, and the statutory requirements governing prior convictions.
Why the Details of a DWI Matter
The potential punishment for a Texas DWI depends on more than whether it is labeled a first, second, or third offense. The State may consider prior qualifying convictions, the alleged alcohol concentration, the presence of a child passenger, whether someone was injured or killed, and other circumstances that can change the classification or punishment.
