Texas runs a zero-tolerance system for drivers under 21 — and it confuses almost everyone, because a minor can be charged with two completely different offenses depending on the circumstances.
DUI vs. DWI for under-21 drivers
| DUI (under 21) | DWI | |
|---|---|---|
| Who it applies to | Drivers under 21 only | Any driver, including minors |
| Standard | Any detectable amount of alcohol | Intoxication or BAC 0.08+ |
| Charge level | Class C misdemeanor | Class B misdemeanor or higher |
| Fine | Up to $500 | Up to $2,000 (1st offense) |
| Jail | None (Class C) | 72 hours–180 days |
| License suspension | 60 days (1st), 120 days (2nd), 180 days (3rd+) | 90 days–1 year |
Translation: a 19-year-old with a 0.02 BAC faces a DUI. The same 19-year-old at 0.09 faces an adult DWI with adult consequences. Officers choose based on the evidence.
Additional penalties for minors
- Mandatory alcohol awareness class (with a parent sometimes required to attend)
- 20–40 hours of alcohol-related community service (up to 60 for repeat offenses)
- Third offense at age 17–20 can mean up to 180 days in jail and a $2,000 fine
Why an underage charge deserves a serious defense
A DUI or DWI on a young person's record surfaces on college applications, scholarship reviews, professional licensing (nursing, teaching, law, finance), and every employment background check. The good news: underage cases have the widest range of favorable outcomes in Texas DWI law — deferred dispositions, dismissals after class completion, and expunction eligibility for Class C DUI cases that end without conviction.
For parents
Minors are typically released to a parent after arrest, but the deadlines still run — including the 15-day ALR window to fight the license suspension. For a student who drives to school or work, an ALR hearing and, if needed, an occupational license petition can be the difference between a detour and a disaster.
