What Is Florida’s Zero Tolerance Law for Underage DUI?

Florida’s zero tolerance law for underage DUI makes it illegal for anyone under 21 to drive with a blood-alcohol level of 0.02% or higher, roughly a quarter of the 0.08% limit that applies to adult drivers.¹ A single beer can push a lightweight person past that number. If a breath or blood test comes back at 0.02% or above, the officer takes the license on the spot and issues a notice of suspension. No court appearance, no judge, no warning.

What a 0.02% Reading Actually Triggers

The suspension runs through the Department of Highway Safety and Motor Vehicles under Florida Statute 322.2616, not through the criminal courts. That matters because the standard protections of a criminal case don’t apply unless the BAC is also high enough to charge a regular DUI. The administrative penalty moves faster and gives the driver less room to contest it.

Refusing the breath test doesn’t make the problem go away. The law treats a refusal as its own violation, and the penalty for refusing is deliberately steeper than the penalty for blowing a low positive.

How Long the License Is Gone

The clock starts on the date the notice of suspension is issued, not the date of any later hearing.

The 0.05% Add-On You Can’t Wait Out

If the reading hits 0.05% or higher, the suspension doesn’t end on its own. The driver has to complete a substance abuse course through a state-licensed DUI program, pay for it themselves, and sit through a substance abuse evaluation before the department will reinstate the license.¹ For drivers under 19, the program sends the evaluation results to the parents or legal guardians.

Skip the course and the suspension stays in place indefinitely, even after the six-month or one-year period has technically run.

The 10-Day Window to Fight It

You have 10 days from the date on the notice of suspension to request a review. Miss that window and the suspension stands.²

Two options exist. An informal review is paper-only; a hearing officer looks at what the arresting officer submitted alongside anything the driver submits, and no one appears in person. A formal review is a live proceeding where a hearing officer can take testimony and evidence. Either way, the department has to schedule the review within 30 days of the request.²

While the review is pending, the department issues a temporary driving permit limited to business purposes, good until the hearing date. The hearing officer can sustain, amend, or invalidate the suspension, but the scope is narrow. For a BAC-based suspension, the questions are whether the officer had probable cause for the stop, whether the driver was actually under 21, and whether the test result was 0.02% or higher. For a refusal, the officer also looks at whether the driver was properly warned about what refusing would cost them.²

Getting to Work During the Suspension

A full suspension doesn’t necessarily mean no driving. Someone whose license is suspended under this law can apply for a business-or-employment-only license under Florida Statute 322.271, if they’re otherwise eligible.² The waiting rule: you can’t apply until at least 30 days after your last temporary driving permit has expired. For a young person who needs to drive to a job or to classes, that gap is real, but the restricted license is worth filing for the moment the waiting period clears.

When It Crosses Into Criminal DUI

Zero tolerance is an administrative process. It doesn’t replace criminal DUI law. If an underage driver’s BAC hits 0.08% or higher, Florida Statute 316.193 applies the same way it applies to an adult, because the statute opens with “a person” and sets no age floor.³ The criminal case runs alongside the administrative suspension through a different system entirely.

A conviction adds consequences the DMV process can’t impose on its own: fines, possible jail time, a DUI on the permanent record, and a separate license revocation ordered by the court. At 0.15% or higher, the enhanced penalties under 316.193(4) kick in, including a minimum $1,000 fine for a first conviction.³ A reading of 0.10% on an 18-year-old triggers both tracks at once: an automatic zero tolerance suspension through the department and a criminal DUI prosecution in court.
