Texas zero-tolerance law applies to drivers under 21: any detectable amount of alcohol while operating a motor vehicle in a public place can trigger DUIA-by-a-minor consequences. There is no 0.01% threshold. DUIA, DWI, and Administrative License Revocation (ALR) are separate legal tracks and should not be blended together.
Texas defines a minor for these alcohol rules as a person under 21. The zero-tolerance rule uses any detectable amount of alcohol, not 0.01%.
| Situation | Core Rule | Typical First-Offense License Consequence |
|---|---|---|
| DUIA by a minor | Any detectable amount of alcohol while operating in a public place. First offense is a Class C misdemeanor. | 60-day suspension for a first detectable-alcohol offense; later offenses can be 120 or 180 days. |
| DWI by a minor | A minor can also be charged under the adult DWI law when the DWI elements are met. | A first DWI is a Class B misdemeanor and can carry a one-year driver-license suspension, subject to the specific court disposition. |
| ALR refusal | Separate administrative action for refusing the requested breath/blood specimen. | 180 days for a first minor refusal; 2 years for a second or subsequent refusal. |
A first DUIA offense can also include a fine up to $500, 20 to 40 hours of community service, and an alcohol-awareness requirement. See the current Texas DPS Zero Tolerance brochure (DL-20).
The ALR process is separate from the criminal case. A driver who receives the ALR notice generally has 15 days to request a hearing.
Complete the compliance items shown by DPS for the specific enforcement action and pay the applicable reinstatement fee when required.
There is no universal 30-day waiting period before every occupational-license petition. Eligibility depends on the suspension and the court order. Use the DPS occupational-license guidance for the exact case.
If the learner license is suspended while the six-month holding period is running, the holding period is extended by the suspension duration; it does not restart from zero.
Yes, separate criminal or zero-tolerance action and administrative license action can arise from the same incident. DPS describes ALR as a civil administrative process that is separate from the criminal case, and it notes that more than one suspension can result from the same alcohol-related event depending on the facts. See Texas DPS ALR guidance.
For a minor, refusal and a detected/failed alcohol result are not the same suspension. DPS lists a first minor refusal at 180 days, while a first detectable-alcohol offense carries a 60-day suspension; later offenses have different periods. The exact case can also include DWI or other actions, so use the notice issued for the stop rather than assuming one timeline applies to both. See the DPS ALR FAQ.
Possibly, but it is not automatic. An occupational license requires a court order and eligibility depends on the specific suspension and restrictions. DPS also notes that an occupational license is valid only in Texas. Use the court and DPS occupational-license process for the individual case. See DPS occupational-license FAQ.
Alcohol-related cases can affect licensing, insurance, court requirements, and the timing of the next licensing step. The exact consequences depend on whether the case is DUIA, DWI, ALR failure, ALR refusal, or a combination.
Do not assume that every permit alcohol case is a Class C misdemeanor or that every suspension lasts 180 days. Repeat offenses and DWI convictions carry different penalty structures.
For ordinary speeding, supervision, cellphone, or other learner-license violations, use the separate Traffic Violations on Permit guide. Keep this page focused on alcohol-related rules.
Yes. When a learner license is suspended during Phase I, Texas DPS extends the initial six-month holding period by the number of days of the suspension. It does not restart the period from zero. See Texas DPS learner-license rules.
What if the alcohol or DWI offense happens outside Texas? An out-of-state offense can still affect a Texas license. DPS may take action when another state's conviction would be grounds for suspension, revocation, or denial in Texas, or when the person's driving privilege is withdrawn in the other state. See Texas DPS out-of-state offense guidance.
"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"

"I was struggling with the specific road rules of my state until I used Shoro. The flashcards are a game changer for quick revision before the actual exam."

"The readiness score gives you so much confidence. I knew exactly when I was ready to take the test. Highly recommend Shoro for anyone nervous about their exam."
