Under-21 DUI Charges in San Antonio, TX
Under-21 DUI in San Antonio: a separate charge from DWI
One of the most common points of confusion in Texas is the difference between DWI and DUI. For a driver under 21, Texas has a zero-tolerance law: any detectable amount of alcohol can lead to a DUI charge under the Alcoholic Beverage Code, even when the driver is well below the level that would support an adult DWI. It is a different offense with different consequences, and for a young person it can affect college, jobs and a driving record for years.
San Antonio DWI Defense is an independent local guide. We are not a law firm and we do not provide legal services or representation. We help people arrested in the San Antonio and Bexar County area understand the process and connect with a verified, licensed local DWI defense attorney for a free, confidential case review.
How under-21 DUI differs from adult DWI
- The threshold. DUI for a minor is based on any detectable alcohol, not the adult intoxication standard, so a much smaller amount can trigger it.
- The charge. A first under-21 DUI is generally a Class C misdemeanor, but it still carries fines, license suspension, mandatory programs and a record, and a higher alcohol level can mean the minor is charged with DWI instead, which is more serious.
- The license impact. License suspension and required programs hit young drivers hard, and there can be school and insurance consequences that outlast the case itself.
Why early, honest advice matters for a young person
Because the long-term record and license effects can outweigh the immediate penalty, how a minor's DUI is handled at the start really matters. An experienced attorney can explain eligibility for programs that may keep a young person's record clean, without promising any particular result.
Comparing attorneys for an under-21 case

Compare verified San Antonio DWI attorneys
Tell us a little about your situation, the charge, whether it is a first offense, and how recently you were arrested, and we will help you compare verified, licensed San Antonio-area DWI defense attorneys and request a free, confidential case review.

This page is general legal information, not legal advice, and it does not create an attorney-client relationship. DWI and DUI laws are complex and every case turns on its own facts. Deadlines (including the deadline to request an ALR license hearing) are short and unforgiving. Only a licensed Texas criminal-defense attorney can advise you on your specific situation. If you have been arrested, speak with a qualified attorney promptly.
Frequently asked questions
No. San Antonio DWI Defense is an independent local guide. We help people arrested for DWI or DUI in the San Antonio area understand their situation and connect with a verified local criminal-defense attorney for a free case review. We are not a law firm, we do not represent you, and nothing here is legal advice.
In Texas they are separate charges. DWI (Driving While Intoxicated, Penal Code 49.04) is the charge for drivers 21 and over. DUI (Alcoholic Beverage Code 106.041) is a separate under-21 minor charge that applies to any detectable amount of alcohol. Because the offenses, penalties and defenses differ, it matters which one you are facing — a licensed Texas attorney can confirm your specific charge.
An arrest triggers two separate tracks: the criminal case in court and an Administrative License Revocation (ALR), a civil DPS action to suspend your license. You generally have a hard deadline — commonly cited as 15 days from the notice of suspension — to request an ALR hearing, or the suspension takes effect automatically. Because that deadline is short and easy to miss, many people speak with a defense attorney promptly. We can help you compare local attorneys, but only a licensed Texas attorney can advise on your specific deadline.
It depends on the charge (first offense, repeat, felony), whether the case goes to trial, and the attorney. DWI defense commonly runs into the thousands of dollars in attorney fees, and many attorneys offer a free initial case review. We do not quote a fee — a local attorney gives you an exact estimate after reviewing your case.
Favor an attorney licensed in Texas with real DWI / criminal-defense experience and familiarity with the Bexar County courts and DPS process. Insist on a clear explanation of both the criminal case and the ALR license track, and be cautious of anyone who guarantees a result — no honest attorney can promise an outcome. Tell us your area and situation and we help you compare verified local attorneys.
No. No honest attorney guarantees a result, and Texas attorney-advertising rules bar unfounded result claims. Every case is different. A reputable attorney explains the process, the realistic range of outcomes and the risks — not a promised result. This guide provides general information only and is not legal advice.
