Texas has two distinct underage alcohol-driving offenses: DUI by Minor under Alcoholic Beverage Code § 106.041 (any detectable alcohol — Class C misdemeanor) and DWI under Penal Code § 49.04 (BAC ≥ 0.08, intoxicated, or substance-impaired — Class B misdemeanor or higher). Both produce mandatory license suspensions for drivers under 21.
Texas zero-tolerance law for drivers under 21 means any detectable alcohol while operating a motor vehicle is a Class C misdemeanor — even if the driver is not impaired. The more serious DWI charge applies when the driver is over 0.08 BAC or otherwise intoxicated. License suspensions are mandatory, with severe academic and family consequences.
DUI by Minor — § 106.041
Alcoholic Beverage Code § 106.041 — DUI by Minor — applies to operators under 21 with any detectable amount of alcohol. Penalties:
- Class C misdemeanor;
- $0 to $500 fine;
- Mandatory community service (8-12 hours for first offense, 20-40 for subsequent);
- Mandatory alcohol awareness program;
- Driver's license suspension (60 days for first; 120 days for second; 180 days for third).
Class C tickets do not produce jail time, but they do create a record. Multiple offenses can elevate to a Class B misdemeanor under § 106.041(b).
DWI — § 49.04
Penal Code §49.04 applies regardless of age when the driver is intoxicated:
- BAC ≥ 0.08, OR
- Lacks normal use of mental or physical faculties due to alcohol or drugs.
Penalties:
- First offense: Class B misdemeanor — up to 180 days jail, $2,000 fine;
- BAC ≥ 0.15: Class A misdemeanor — up to 1 year jail, $4,000 fine;
- Second offense: Class A misdemeanor;
- Third or subsequent offense: third-degree felony — 2-10 years TDCJ;
- DWI with child passenger under 15 (§ 49.045): state jail felony — 180 days to 2 years.
For drivers under 21, DWI charges are filed in juvenile court if the offender is under 17 at the time of the offense.
License Suspensions
Both offenses trigger mandatory license suspension, plus the Administrative License Revocation (ALR) process:
ALR — Independent of Criminal Case
If the driver refuses or fails the breath/blood test, DPS suspends the license administratively under Transportation Code § 524 (test failure) or § 724 (refusal). The driver has 15 days to request an ALR hearing.
Conviction Suspensions
- DUI by Minor first offense: 60-day suspension;
- DUI by Minor second: 120 days;
- DUI by Minor third: 180 days;
- DWI under 21: 180 days to 2 years (depending on offense and history).
Occupational Driver's License
Family Code § 521.242 allows juvenile DWI defendants to seek an occupational license — limited driving for school, work, and essential needs. See our occupational license guide.
Implied Consent and Blood Draws
Texas implied consent law applies to drivers under 21:
- Refusal to submit to breath or blood test triggers automatic 180-day ALR suspension (2 years for prior refusal);
- Failure (BAC ≥ 0.08, or detectable alcohol for under 21) triggers automatic 90-day ALR suspension (1 year for repeat);
- For DWI cases (not DUI by Minor), officers can seek search warrants to compel blood draws if the driver refuses.
The decision to take or refuse the test is critical. Defense counsel should advise pre-arrest if possible.
Defenses
Suppression — Stop / Investigation
Most underage cases involve traffic stops or accident scenes. Fourth Amendment challenges to the stop, the investigation, and any blood/breath test can suppress evidence.
BAC Challenges
Breath test calibration, observation period, blood test chain of custody, lab procedures — all routinely challenged.
"Operating" Element
Both DUI by Minor and DWI require operation of a motor vehicle. Sleeping drivers, drivers waiting in parked cars, and drivers who got out of the vehicle before officer contact present operation challenges.
Source of Detection
For DUI by Minor, the trace amount can come from non-impairing sources — recent mouthwash, food, fermentation, residual alcohol from earlier consumption. While not a complete defense, source evidence can support reduction or dismissal.
Alibi for Identification
In rare cases — particularly accident scenes where the driver fled — identification of the actual operator becomes the central issue.
Collateral Consequences
- Insurance increases — typically 50-200% rate increases for 3+ years;
- College admissions — DWI conviction triggers federal student aid suspension (limited to drug-related and certain offenses);
- Employment — driving-related jobs (delivery, ride-share, commercial driving) generally barred;
- Military enlistment — typically requires waiver;
- Professional licensing — nursing, healthcare, teaching, law enforcement — case by case;
- Immigration — DWI typically not deportable but multiple offenses can be.
What to Do If Your Child Is Charged
- Do not let your child speak to police without a parent and an attorney present. Texas allows juvenile statements only with strict procedural safeguards under Family Code § 51.095.
- Demand a magistrate warning before any juvenile interview — required by § 51.095 for any custodial statement to be admissible.
- Preserve school records, social media, and texts — but do not delete anything.
- Do not contact alleged victims, witnesses, or co-respondents — bond and probation conditions usually prohibit it.

Frequently Asked Questions
What's the difference between DUI by Minor and DWI in Texas?
DUI by Minor (§ 106.041) requires only any detectable alcohol — Class C misdemeanor. DWI (§ 49.04) requires intoxication (BAC ≥ 0.08 or impairment) — Class B misdemeanor minimum.
Will my child lose their license for a DUI?
Yes. Mandatory suspension applies — 60 days for first DUI by Minor, 90-180 days for ALR. Occupational license is available for limited driving needs.
Can a juvenile DWI go on the adult record?
Cases for offenders 17+ at the time of the offense are filed in adult court — they are not juvenile cases. For juveniles under 17, the case is in juvenile court but can be sealed under Family Code § 58.253 in some circumstances.
Is the ALR hearing the same as the criminal case?
No — separate process. ALR is administrative; the criminal case is in court. ALR results do not bind the criminal case (and vice versa). Both must be defended.
Can I refuse the breath test?
Yes, but refusal triggers automatic 180-day license suspension under Transportation Code § 724.013. For some drivers, refusal is the right call; for others, it isn't. Pre-arrest legal advice is ideal.
