A DUI at nineteen or twenty is not just a legal problem, it is a threat to a young person’s license, their place in school, and a record that follows them into every job application for years. Florida treats under-21 drivers under a separate, stricter set of rules, and understanding both tracks, the administrative and the criminal, is the first step to protecting a future.
The 0.02 rule, and the two tracks
For drivers under 21, the limit is 0.02, not 0.08. Under section 322.2616, a reading that low triggers an administrative license suspension on its own, even with no criminal charge, because a single drink can put a young driver over it. Separately, if the reading reaches 0.08 or the officer claims impairment, the driver faces a full criminal DUI under section 316.193. One incident can put both tracks in motion, and they run on different clocks with different consequences.
| Situation | BAC | Track | Main consequence |
|---|---|---|---|
| Under 21, 0.02 to 0.079 | 0.02+ | Administrative only | 6-month license suspension, no criminal charge |
| Under 21, second 0.02 violation | 0.02+ | Administrative only | 1-year license suspension |
| Under 21, 0.05 or higher | 0.05+ | Administrative only | Suspension until a substance-abuse course is completed |
| Under 21, refusal | Refused | Administrative only | 1-year suspension, 18 months for a repeat |
| Under 21, 0.08+ or impaired | 0.08+ | Criminal and administrative | Full DUI under section 316.193, plus the suspension |
The 0.02 zero-tolerance suspension is administrative under section 322.2616 and is separate from a criminal DUI under section 316.193. A driver cannot be suspended under both 322.2615 and 322.2616 for the same episode. Procedures and figures last verified June 2026.

Why an underage DUI is worth fighting hard
The stakes reach well past the courtroom. A conviction can never be sealed in Florida, so it stays on background checks seen by employers, graduate schools, and licensing boards. A student can face university conduct sanctions for an off-campus arrest. And a young driver’s insurance can climb for years. Because so much rides on the record, the goal is almost always to protect it, by fighting the suspension, challenging the evidence, and keeping a conviction off the books.
I started out as an Assistant Public Defender in Florida’s Thirteenth Judicial Circuit, in Tampa, and today I am one of six ACS-CHAL Forensic Lawyer-Scientists in Florida. For a young driver, the goal is to protect both the license and the record, because a conviction at nineteen can follow you into every job and school application that comes later.

Under-21 DUI questions
What is the legal limit for drivers under 21 in Florida?
For drivers under 21, the limit is 0.02, not the 0.08 that applies to adults. This is Florida's zero-tolerance law under section 322.2616. A reading of 0.02 is so low that a single drink can cross it, and it triggers an administrative license suspension even when no criminal DUI is charged.
Is an underage DUI a criminal charge?
Not always. A reading between 0.02 and 0.08 is handled administratively through a license suspension, with no criminal charge. But if the reading is 0.08 or higher, or the officer believes the driver was impaired, the under-21 driver can face a full criminal DUI under section 316.193 on top of the suspension.
How long is the license suspension for an under-21 driver?
A first zero-tolerance violation suspends the license for six months, and a second for one year. If the reading was 0.05 or higher, the suspension stays in effect until the driver completes a substance-abuse course. A refusal to test carries a one-year suspension, or 18 months for a repeat.
Will a DUI affect my college standing?
It can. Florida universities including USF, UF, FSU, and UCF have student conduct codes that can impose sanctions for an off-campus arrest, including loss of housing, scholarship consequences, and in serious cases suspension. That collateral risk is one of the biggest reasons to fight an underage DUI rather than just accept it.
Can an underage DUI be kept off my record?
Often that is the whole goal. A conviction can never be sealed, but a charge that is dismissed, reduced, or resolved with a withhold of adjudication can frequently be sealed later, which keeps it off most background checks. For a young person with a future of job and school applications, protecting the record is usually the priority.
This page is general information about Florida law, not legal advice, and it does not create an attorney-client relationship. The under-21 zero-tolerance suspension is governed by section 322.2616, Florida Statutes, and a criminal DUI by section 316.193. Deadlines are short and the rules change, so confirm current requirements with the DHSMV or an attorney. Every case turns on its own facts, and past results do not guarantee a similar outcome.
