Texas DWI Laws Explained
Under Texas Penal Code §49.04 (see: https://statutes.capitol.texas.gov/Docs/PE/htm/PE.49.htm), a person commits DWI if they are intoxicated while operating a motor vehicle in a public place.
Legal Limits
• Adult drivers (21+) – BAC of 0.08% or higher.
• Commercial drivers – BAC of 0.04% or higher.
• Drivers under 21 – Any detectable alcohol is illegal (zero-tolerance).
Texas also defines intoxication as lacking the normal use of mental or physical faculties due to alcohol, drugs, or a combination of substances.
Penalties for DWI in Texas
DWI penalties increase sharply with each conviction or if aggravating factors are present (child passengers, open containers, or crashes with injuries).
First Offense (Class B Misdemeanor)
Up to $2,000 fine, 72 hours to 180 days in jail, and 90 days to 1 year license suspension.
Second Offense (Class A Misdemeanor)
Up to $4,000 fine, 30 days to 1 year in jail, and up to 2 years license suspension.
Third Offense (Third-Degree Felony)
Up to $10,000 fine, 2 to 10 years in prison, and up to 2 years license suspension.
Additional Consequences
• Ignition Interlock Devices – Mandatory for repeat or high-BAC offenders.
• Alcohol Education Programs – Court-ordered DWI education or intervention classes.
• Community Service & Probation – Often imposed alongside jail or fines.
• Bentley’s Law (2023) – Requires DWI offenders who kill a parent in a crash to pay child support.
• SR-22 Insurance – High-risk insurance required for license reinstatement.
• Occupational Licenses – Many drivers must request restricted licenses to keep working during suspension.
Collateral Consequences of a DWI Conviction
Beyond fines and jail, a DWI conviction can impact your life in other significant ways:
• Employment opportunities, especially jobs requiring driving.
• Immigration status for non-citizens.
• Professional licenses (nurses, teachers, commercial drivers).
• Child custody or family law cases.
• Auto insurance premiums for years after conviction.
DWI Defense Strategies in Texas
At The Napier Law Firm, we analyze every detail of your case, from the legality of the stop to the reliability of the evidence. Common defenses include:
• Illegal Traffic Stop – Police must have reasonable suspicion or probable cause.
• Improper Field Sobriety Tests – Errors due to health issues, poor conditions, or officer mistakes.
• Breathalyzer & Blood Test Errors – Machines must be calibrated; blood samples must be handled correctly.
• Rising BAC Defense – BAC may have been under the limit while driving but rose later.
• Medical Conditions – GERD, diabetes, or keto diets can cause false positives.
• Violation of Rights – Evidence can be thrown out if constitutional rights were violated.
• Officer Credibility – Exposing inconsistencies in testimony.
We also represent clients at Administrative License Revocation (ALR) hearings, where you can fight to keep your driver’s license (see Texas DPS ALR info: https://www.dps.texas.gov/section/driver-license/alr-program).
