TL;DR
Complete guide to Texas DWI: Penal Code §49.04, BAC limits, license suspension, breath/blood tests, deferred adjudication, defense strategies, plea outcomes.
Quick Answer
#1 - The offense is broader than "drunk driving"
Penal Code §49.04 covers operating a motor vehicle in a public place while intoxicated. Each word matters: "operate" includes sleeping in driver's seat with engine running. "Motor vehicle" includes cars, trucks, motorcycles, e-scooters in some contexts. "Public place" includ…
Table of Contents
Texas DWI law touches more statutes, more codes, and more parallel proceedings than most people realize. This is the comprehensive reference — the twelve things every Texas DWI defendant needs to understand. Bookmark it, share it with family, refer back as the case progresses. The case will go through three or four phases over 6-12 months; different items below will become relevant at different times.

#1 - The offense is broader than "drunk driving"

Penal Code §49.04 covers operating a motor vehicle in a public place while intoxicated. Each word matters: "operate" includes sleeping in driver's seat with engine running. "Motor vehicle" includes cars, trucks, motorcycles, e-scooters in some contexts. "Public place" includes parking lots, alleys, apartment common areas. "Intoxicated" means either BAC 0.08+ OR loss of normal faculties from any substance including prescription medications.

#2 - There are two ways the state proves intoxication

The "per se" theory: BAC 0.08 or higher from breath/blood test. The "loss of faculties" theory: officer observations, field sobriety performance, driver behavior. Either theory supports conviction. Refusing the breath test eliminates per se but doesn't prevent loss-of-faculties prosecution.

#3 - You have 15 days to request an ALR hearing

The Administrative License Revocation hearing is a civil proceeding separate from criminal court. Missing the 15-day deadline = automatic license suspension. Even if you lose the ALR hearing, the case provides discovery (officer testimony under oath) that benefits the criminal case.

#4 - Breath tests can be challenged on multiple fronts

Calibration records (was Intoxilyzer 9000 properly maintained?), operator certification (was officer qualified?), observation period (was 15-minute pre-test observation actually maintained?), mouth alcohol contamination, physiological factors (breath-blood ratio varies). Each is a separate technical defense.

#5 - Blood tests require warrants (with limited exceptions)

Under Birchfield v. North Dakota (2016), forced blood draws generally require search warrants. Defense can challenge: warrant affidavit sufficiency, sample handling, chain of custody, lab protocols. Texas Code of Criminal Procedure art. 38.43 allows defense-funded retest.

#6 - Mandatory minimums exist but rarely require actual jail time

72 hours minimum for Class B (under 0.15 BAC). 6 days minimum for Class A (0.15+ BAC). 30 days minimum for 2nd DWI. Time served during initial arrest typically counts. Weekend service available in many counties. Deferred adjudication (post-2019) avoids the minimum entirely.

#7 - Five paths from misdemeanor to felony

Third DWI (3rd-degree felony). DWI with child passenger under 15 (state jail felony, any offense). Intoxication assault (3rd-degree felony). Intoxication manslaughter (2nd-degree felony). Specific enhancement scenarios (interlock violation, prior felony intoxication-related conviction).

#8 - Texas has no DWI lookback period

Unlike most states with 5, 10, or 15-year lookback periods, Texas counts every prior DWI conviction in your lifetime. A 1990 conviction counts for a 2026 case. Out-of-state DWIs count. BWI and FWI count.

#9 - The 2019 reforms changed the landscape

HB 3582 (2019) authorized deferred adjudication for first DWI. HB 2048 (2019) repealed the Driver Responsibility Program surcharges. SB 1418 (2019) expanded ignition interlock requirements. The pre-2019 framework was substantially harsher; cases filed today have meaningful new options.

#10 - The total cost is $8,000-$22,000

Criminal court costs ($1,000-$5,000), defense attorney fees ($3,000-$8,000), probation costs ($1,000-$2,500), license-related expenses ($500-$1,500), insurance increases over 3-5 years ($2,000-$5,000). Insurance is often the single largest category.

#11 - Realistic outcomes range across six dispositions

Dismissal after suppression. Pretrial diversion (county-specific). Reduction to obstruction of highway or reckless driving. Deferred adjudication on DWI. Standard probation with conviction. Direct sentence with jail time. The path depends on defense work in the first 60-90 days.

#12 - Long-term record clearance is possible (sometimes)

Dismissals are expunction-eligible 1 year post-dismissal under Code of Criminal Procedure ch. 55. Deferred adjudication completion is nondisclosure-eligible 2 years after discharge (under-0.15 BAC) or 5 years (0.15+) under Government Code §411.0731. Final convictions cannot be expunged or sealed for DWI.

Frequently Asked Questions

What is the BAC limit in Texas?

0.08 for adult drivers in passenger vehicles. 0.04 for commercial drivers (CDL). Any detectable amount for drivers under 21 (zero tolerance under Penal Code §49.05). Above 0.15 enhances first DWI from Class B to Class A misdemeanor.

Can I refuse a breath test?

Yes, but with consequences. Refusal triggers automatic 180-day ALR suspension and creates an inference at trial. Police can obtain a search warrant for forced blood draw upon refusal in most cases. The strategic value of refusal depends on circumstances: refusal eliminates BAC evidence but creates other problems.

How long does a DWI stay on my record?

A conviction stays permanently — cannot be expunged. A successfully completed deferred adjudication can be sealed via order of nondisclosure under Government Code §411.0731 after 2 years (under-0.15) or 5 years (0.15+). Sealing makes the record invisible to most employers and licensing boards but not to law enforcement or government background checks.

Can I get my license back during the DWI case?

Yes, through occupational driver's license under Transportation Code Chapter 521 Subchapter L. Allows limited driving for work, school, household necessities, and probation requirements. Application process requires hearing, SR-22 insurance, and specific procedures. An attorney can typically secure occupational license within 60-90 days of arrest.

What does a DWI cost overall?

For a typical first DWI in Texas, total cost runs $8,000-$15,000 over the life of the case. Components: defense attorney fees ($3,000-$8,000), fines and court costs ($1,500-$3,000), surcharges and reinstatement fees ($1,000-$2,000), interlock and monitoring ($500-$1,500), insurance increases over 3-5 years ($2,000-$5,000), missed work and other indirect costs (variable).
