Underage DUI in Miami

A Former Miami-Dade Prosecutor Now Fights the Charges He Once Built

Florida’s zero-tolerance law sets a BAC threshold of 0.02% for drivers under 21, so low that a single drink can trigger an arrest, an automatic license suspension, and a criminal record with lasting consequences. A charge like this moves fast. The 10-day window to contest the administrative suspension begins at arrest, not at arraignment, and missing it may forfeit that opportunity at that stage.

At The Law Offices of Eric M. Matheny, P.A., we defend drivers under 21 facing DUI charges in Miami and throughout Miami-Dade County. Attorney Eric Matheny spent years as a Miami-Dade County prosecutor before moving to defense, which means he knows how the state builds these cases and where they may be vulnerable to challenge. That perspective shapes strategy from the first consultation.

What Florida’s Zero-Tolerance Law Actually Does

Florida Statute § 322.2616 prohibits drivers under 21 from operating a vehicle with a BAC of 0.02% or higher. That threshold is far below the 0.08% adult standard under Florida Statute § 316.193, and prosecutors don’t need to prove any visible impairment to pursue a violation. A measurable BAC reading may be enough.

The zero-tolerance framework creates two separate tracks of consequences. Administrative penalties, including license suspension, can take effect before any court date through the Department of Highway Safety and Motor Vehicles (DHSMV). Criminal charges are a separate matter entirely. A driver can face both, or face administrative action even without a criminal conviction. When a driver under 21 tests at 0.08% or higher, or is otherwise impaired by alcohol or drugs, the full adult criminal DUI charge under § 316.193 may apply alongside the administrative consequences.

Penalties by BAC Level

The consequences for an underage DUI in Florida depend on the BAC reading, the driver’s age, and prior history. Here’s how the tiers break down:

Administrative penalties (BAC 0.02% to below 0.08%):

• First offense: six-month license suspension
• Second offense: one-year license suspension
• BAC of 0.05% or higher: mandatory substance abuse course before reinstatement
• Refusal to submit to testing: 12-month suspension for a first refusal, 18 months for a second

Criminal DUI (BAC 0.08% or higher):

• Fines of $500 to $1,000 for a first offense
• Up to six months in jail
• License revocation of 180 days to one year
• At least 50 hours of community service
• Drivers under 18 may also face additional requirements, including an alcohol education program

A charge involving serious bodily injury or death can be elevated to a felony regardless of prior record. Following arrest, a temporary permit is typically issued for 10 days, which is also the window to request a formal DHSMV review hearing.

Consequences That Follow a Conviction

A DUI conviction doesn’t end at sentencing. For a young person, the collateral consequences can outlast the legal penalties by years.

Education and employment:
Many universities require disclosure of criminal convictions in admissions applications and may rescind scholarships. A DUI on a background check can also disqualify a young person from jobs requiring driving or professional licensure in fields such as healthcare, law, and education.

Insurance and financial impact:
Car insurance premiums typically increase significantly after a DUI arrest and can remain elevated for years, adding thousands of dollars in costs over time.

Immigration consequences:
For non-citizens, certain DUI-related convictions can carry serious immigration consequences, including deportation proceedings or bars to naturalization, depending on the specific charge and immigration status.

Criminal record:
Under Florida law, a DUI conviction can’t be sealed or expunged. However, if charges are dismissed, dropped, or reduced to a lesser offense such as reckless driving with adjudication withheld, the arrest record may be eligible for sealing or expungement under specific eligibility conditions. We evaluate each client’s situation for those options.

How We Defend Underage DUI Charges in Miami

Attorney Matheny’s prosecutorial background is the foundation of our defense approach. He understands how DUI evidence is assembled, how it’s presented, and where it can be challenged. Every case gets a full review before any strategy is set.

Challenging the traffic stop:
A stop requires reasonable suspicion. If that standard wasn’t met, evidence gathered after the stop may be suppressible.

Disputing field sobriety test results:
Performance on field sobriety tests can be affected by medical conditions, fatigue, road conditions, footwear, and improper administration, not only by alcohol. We review how tests were conducted and whether results were fairly recorded.

Questioning BAC test accuracy:
Breathalyzer results can be challenged on grounds of equipment calibration, operator certification, testing procedures, chain of custody, or mouth alcohol interference. A rising BAC defense may also apply if testing occurred well after the stop.

Constitutional violations:
Unlawful searches, coerced statements, and Miranda violations are independently reviewable grounds for suppression.

Diversion and alternative resolutions:
For first-time offenders, pretrial diversion programs and substance education enrollment may allow a client to avoid a conviction or limit its record impact. We evaluate eligibility for these options in each case.

We represent clients in both DHSMV administrative hearings and Miami-Dade County criminal court. Attorney Matheny has tried more than 50 jury and non-jury trials and prepares every case as though it will go to trial, which can strengthen our negotiating position at every stage.
