St. Patrick’s Day celebrations often include festive gatherings, parades, and—famously—green beverages. While the holiday is associated with celebration and community, it also offers an opportunity to highlight an important legal topic: driving while intoxicated (DWI) and the legal consequences that can follow.
At the Harris County Robert W. Hainsworth Law Library, we regularly assist patrons and legal professionals seeking information about Texas criminal law. For those looking to better understand DWI law—whether for educational purposes, legal research, or personal information—the library provides a range of statutes, treatises, and self-help resources.
Texas Law on Driving While Intoxicated
In Texas, DWI offenses are primarily defined in the Texas Penal Code § 49.04, which makes it an offense to operate a motor vehicle in a public place while intoxicated. Intoxication may be established by:
A blood alcohol concentration (BAC) of 0.08 or higher, or
Loss of normal use of mental or physical faculties due to alcohol, controlled substances, prescription drugs, or other intoxicants.
Additional statutes in Chapter 49 of the Texas Penal Code address related offenses such as intoxication assault and intoxication manslaughter.
DWI Treatises and Practice Guides
The law library maintains a number of specialized resources that analyze Texas DWI law and procedure from both prosecution and defense perspectives. Titles in the collection include:
Baker’s Texas Drugs & DWI Handbook by Lang Baker
Driving While Intoxicated: Texas Cases & Forms – Prosecution and Defense by David Chapman
DWI Defense Desk Manual by Texas District & County Attorneys Association
DWI Investigation & Prosecution by W. Clay Abbott and Diane Beckham
Texas Drunk Driving Law by J. Gary Trichter and W. Troy McKinney
Texas DWI Law and Practice Handbook by Julie Kay Baker and Kyle C. Simpson
Texas DWI Manual by Deandra M. Grant and Kimberly Griffin Tucker (Also available as an eBook via the Lexis Digital Collection)
These resources discuss statutory interpretation, evidentiary issues, investigative procedures, and litigation strategies, making them valuable references for attorneys and researchers studying intoxication-related offenses.
Occupational Driver’s Licenses
A DWI arrest or conviction may result in suspension of driving privileges. In certain circumstances, individuals may be eligible to apply for an occupational driver’s license, which allows limited driving privileges for essential activities such as work, school, or household duties.

Record Sealing and Nondisclosure
For individuals seeking to move forward after a criminal matter, Texas law provides certain opportunities to limit public access to criminal records. In some cases involving DWI—particularly where specific statutory requirements are met—an individual may be eligible to pursue orders of nondisclosure, which restrict public disclosure of the record.
Information about nondisclosure and record sealing options is available through TexasLawHelp.org, along with explanations of eligibility criteria and procedural steps. Visit the links below for more information or view this previous Ex Libris Juris blog post: Fresh Starts.

Support Resources for Attorneys
Substance use disorders can affect members of every profession, including the legal community. Attorneys who are struggling with alcohol or substance use—or who wish to support a colleague—can find confidential help through the Texas Lawyers' Assistance Program (TLAP). TLAP provides resources, referrals, and support services designed specifically for lawyers and law students.
More information about substance use resources is available at: TLAP Substance Use.
