Waco Underage DWI Lawyers

Waco is a college town. Baylor University, McLennan Community College, and Texas State Technical College all operate within or near the city, and the underage-DWI cases that come out of McLennan County reflect that (Greek life events, game weekends, tailgating, off-campus bars along University Parks and Austin Avenue, and the Robinson / Hewitt / Lorena corridor where many students live). Waco law enforcement polices these cases actively. Underage arrests are not rare, and they are not minor.

A driver under 21 arrested in McLennan County for alcohol-related driving actually faces two possible charges: DUI by Minor under the Alcoholic Beverage Code (zero-tolerance, any detectable amount) and DWI under the Penal Code (adult intoxication standard). The statutory penalty for a first DUI by Minor is modest. The college-admissions, scholarship, financial-aid, NCAA, licensing, and professional-pipeline consequences are not.

Deandra Grant Law represents drivers under 21 and their parents in underage DWI cases across Waco, Hewitt, Woodway, Bellmead, and throughout McLennan County. Call (254) 735-3588 to discuss your case.

Two Different Offenses for One Underage Driver

DUI by Minor — Texas Alcoholic Beverage Code § 106.041

The “zero tolerance” offense. A minor (anyone under 21) commits DUI by Minor by operating a motor vehicle in a public place, or a watercraft, with any detectable amount of alcohol in the minor’s system. The state does not have to prove impairment or a 0.08 BAC; it only has to prove that some measurable amount of alcohol was present. This is the offense most first-time underage drivers are charged with.

DWI — Texas Penal Code § 49.04

The adult DWI offense, which applies to drivers of any age. A minor can be charged with DWI when the state can prove intoxication (the loss of normal use of mental or physical faculties by reason of alcohol, drugs, or a combination, or an alcohol concentration of 0.08 or more). A minor charged with DWI faces the same statutory exposure as an adult, beginning at Class B misdemeanor for a first offense. For Waco college-age defendants with BAC at or above 0.08, DWI is often the charge even though DUI by Minor is also available.

Can a Minor Be Charged with Both?

Yes. A minor over the 0.08 threshold can be charged with DUI by Minor (for having detectable alcohol) and DWI (for being intoxicated). In practice, the McLennan County District Attorney’s Office typically elects based on the strength of the evidence and the particular facts.

DUI by Minor Penalties — TABC § 106.071

First Offense

• Class C misdemeanor.
• Fine up to $500.
• 20 to 40 hours of community service.
• Mandatory alcohol awareness course for the minor (and sometimes the parent).
• 60-day driver’s license suspension.

Second Offense

• Class C misdemeanor.
• Fine up to $500.
• 40 to 60 hours of community service.
• 120-day driver’s license suspension.

Third Offense (if Minor is 17 or Older)

• Class B misdemeanor.
• Fine up to $2,000.
• Up to 180 days in jail.
• 180-day driver’s license suspension.

DWI Penalties for Minors — Same as Adult DWI

When the state charges DWI rather than DUI by Minor, the minor faces the full adult DWI framework under Penal Code § 49.04 and related statutes.

First-Offense DWI

• Class B misdemeanor.
• 72 hours to 180 days in county jail (with a 6-day minimum if an open container was present).
• Fine up to $2,000.
• Driver’s license suspension of 90 days to 1 year under Transportation Code § 521.344.
• Ignition interlock may be required as a condition of bond, particularly for BAC 0.15 or above under Code of Criminal Procedure Article 17.441.

First-Offense DWI with BAC 0.15 or Above

• Class A misdemeanor.
• Up to 1 year in county jail.
• Fine up to $4,000.
• Mandatory ignition interlock under Art. 17.441.

Deferred Adjudication for First-Offense DWI

House Bill 3582 (2019) made deferred adjudication available for certain first-offense misdemeanor DWIs under Penal Code § 49.04 with BAC below 0.15%. Deferred adjudication is not available for DWI with child passenger, prior DWI convictions, or felony DWI. A successful deferred adjudication on a misdemeanor DWI can be sealed under a nondisclosure order pursuant to Government Code Chapter 411, Subchapter E-1.

Administrative License Revocation — Minors

Separate from the criminal case, an ALR proceeding runs on the driver’s license side:

• Refusal of a breath or blood test by any driver, including a minor, triggers an ALR suspension of 180 days on a first refusal and 2 years on a repeat refusal under Transportation Code § 724.035.
• Failed test (BAC 0.08 or higher, or any detectable alcohol for a driver under 21) triggers an ALR suspension of 90 days on a first failed test and longer on repeats under Transportation Code § 524.022.
• The deadline to request an ALR hearing is 15 days from the notice of suspension. Missing the deadline results in automatic suspension.
• The ALR hearing provides cross-examination of the arresting officer under oath months before the criminal trial, making it an important discovery tool.

Juvenile Court vs. Adult Criminal Court

Where the case is heard depends on the minor’s age at the time of the offense:

• Under 17 at the time of the offense: Juvenile court under Family Code Title 3. The case is not technically a criminal prosecution; it is a juvenile justice proceeding. Records have different confidentiality protections, and dispositions are designed to be rehabilitative rather than punitive.
• 17 or older at the time of the offense: Adult criminal court. DUI by Minor cases proceed in McLennan County Justice of the Peace Courts and municipal courts; DWI cases proceed in McLennan County Courts at Law or the Criminal District Courts depending on the offense level.

Texas’ adult-court cutoff of 17 is unusual. Most states treat juveniles as minors until 18. Parents often assume a 17-year-old will be treated as a juvenile; in Texas, the 17-year-old is treated as an adult for criminal purposes.

Expunction and Nondisclosure

TABC § 106.12 Expunction

Texas Alcoholic Beverage Code § 106.12 provides a special expunction for certain alcoholic beverage offenses committed by a minor, including DUI by Minor under § 106.041. Eligibility depends on age, completion of any court-ordered requirements, and the absence of subsequent offenses. The mechanism differs from the general expunction framework under Code of Criminal Procedure Chapter 55A and is often a better fit for DUI by Minor cases.

CCP Chapter 55A Expunction and Nondisclosure

General expunction under Chapter 55A is available for dismissals, acquittals, and certain deferred adjudications. A minor who successfully completes deferred adjudication on a DWI charge may, after waiting periods, seek either expunction or an order of nondisclosure under Government Code Chapter 411, Subchapter E-1.

Collateral Consequences for College-Age Defendants

The criminal penalty is usually the smallest part of the problem. The long-term consequences are:

• College admissions and transfers. Baylor University, Texas A&M, The University of Texas, private universities, and many public flagship schools ask about criminal history on applications. Transfer applications carry the same disclosure obligations.
• Scholarship eligibility. Academic, athletic, and need-based scholarships may be affected by criminal history. Some scholarships include explicit behavioral conduct clauses.
• NCAA eligibility. Athletes at Baylor and other NCAA institutions face separate eligibility review.
• Student conduct proceedings. Baylor University, McLennan Community College, and TSTC conduct separate student-conduct proceedings that can impose probation, suspension, or expulsion independent of the criminal case.
• Federal financial aid. The former FAFSA drug-conviction bar has narrowed in recent years; alcohol-only DUI by Minor typically does not trigger the FAFSA drug bar.
• Driver’s license. Suspension affects school attendance, off-campus employment, internships, and athletic team participation.
• Automobile insurance. Premium increases can be substantial, and insurers may refuse to renew.
• Professional licensing pipelines. Nursing, teaching, law, pharmacy, medicine, engineering, accounting, and other licensed professions inquire about criminal history at program entry and at licensure. A conviction that seems small at 18 becomes a licensing issue at 22, 25, or 30.
• Military recruitment. Discretionary consequence depending on branch and rating.
• Immigration. For non-citizen students, even alcohol-related offenses can affect visa renewal, OPT, and other immigration status issues.

Defense Strategies for Underage DWI Cases

Fourth Amendment and Probable Cause

Traffic stops, field sobriety testing, arrests, and blood warrants are all subject to constitutional review. Suppression motions under Texas’ exclusionary rule (Code of Criminal Procedure Article 38.23) frequently determine the outcome of an underage case.

Forensic Challenges

Ethanol analysis in Texas is performed by headspace gas chromatography with flame ionization detection (GC-FID). Attack points include sample collection, preservative balance, chain of custody, calibration, column chemistry, and measurement uncertainty. 

Field Sobriety Testing

Deandra Grant is a Standardized Field Sobriety Test (SFST) instructor. She teaches the same curriculum administered to law enforcement officers, which allows identification of administration errors that can invalidate HGN, Walk-and-Turn, and One-Leg Stand results.

Pretrial Diversion and Deferred Adjudication

For qualifying first-time cases, pretrial diversion and deferred adjudication under CCP Article 42A can produce resolutions that preserve a clean record and protect future opportunities.

What Parents Should Know

• The minor is the client. The minor holds the attorney-client privilege with retained counsel. Parents typically pay for representation and are welcome at consultations, but the minor is the decision-maker.
• School disclosure. Baylor, MCC, TSTC, Texas ISD high schools, and college and graduate school applications carry separate disclosure obligations that continue long after the case ends.
• The ALR clock is 15 days from the notice of suspension. Acting within 15 days is critical.
• A DUI by Minor that looks minor at 18 is still visible at 24 unless it is expunged. Pursuing available expunction relief at the appropriate time is part of the overall defense strategy.
• The CCP Article 17.441 mandatory interlock applies to minors charged with DWI BAC 0.15+ as it applies to adults.

Where McLennan County Underage DWI Cases Are Heard

DUI by Minor cases (TABC § 106.041) are filed in McLennan County Justice of the Peace Courts or the applicable municipal court (Waco Municipal Court, Hewitt, Woodway, or Bellmead). DWI cases for 17-year-old-and-older defendants (misdemeanor) are filed in the McLennan County Courts at Law. Felony DWI cases (rare for underage defendants but possible under BAC 0.15+ plus other factors, child passenger, repeat DWI, etc.) are filed in the McLennan County District Courts at the McLennan County Courthouse, 501 Washington Avenue, Waco. Juvenile cases (under 17) are heard in juvenile court. The McLennan County District Attorney’s Office prosecutes all criminal cases in McLennan County.

Frequently Asked Questions

My child had one beer. Can they really be charged?

Yes. Texas’ zero tolerance rule under TABC § 106.041 makes it an offense for a driver under 21 to operate a motor vehicle with any detectable amount of alcohol. One beer is not a defense to a DUI by Minor charge.

Is DUI by Minor the same as DWI?

No. DUI by Minor under TABC § 106.041 is a Class C misdemeanor for the first offense, requires only any detectable amount of alcohol, and does not require proof of impairment. DWI under Penal Code § 49.04 is at minimum a Class B misdemeanor, requires proof of intoxication, and applies to drivers of any age.

Can my 17-year-old be tried as an adult for DWI?

Yes. In Texas, a 17-year-old is treated as an adult for criminal-court purposes, including DWI. A 17-year-old with BAC at or above 0.08 can be charged with DWI under § 49.04 and faces the same statutory exposure as an adult.

Will this affect college admissions?

Potentially, yes. Selective universities (including Baylor) ask about criminal history on applications. An unresolved conviction can affect admission decisions at Baylor, other private universities, and public flagship schools. Early defense involvement (particularly on expunction and nondisclosure planning) helps minimize long-term disclosure obligations.

Will Baylor or MCC discipline me on top of the criminal case?

Probably, yes. Baylor University’s Student Conduct Code addresses off-campus conduct, including alcohol-related offenses. McLennan Community College, TSTC, and other area institutions have their own conduct proceedings. These proceedings are separate from the criminal case and can impose suspension, expulsion, or other discipline independent of the criminal outcome.

Can a DUI by Minor be expunged?

Often, yes. TABC § 106.12 provides a specific expunction mechanism for minor alcoholic beverage offenses, including DUI by Minor. Eligibility depends on completion of court-ordered requirements and the absence of subsequent offenses. The timing and procedural steps matter; the expunction is not automatic.
