St. Petersburg Underage DUI Defense Lawyer
A DUI arrest is overwhelming for any driver, but the consequences are even more serious for someone under 21. Florida’s zero tolerance law means that a blood alcohol level as low as 0.02 can result in an underage DUI charge. In St. Petersburg, one mistake at a party or during a night out can lead to a suspended license, a criminal record, and a future filled with barriers.

Florida’s Zero Tolerance Law for Underage Drivers
Under Florida law, any driver under 21 with a blood alcohol concentration of 0.02 or higher can face an underage DUI charge. This is part of Florida‘s zero tolerance policy, which applies even if the person is not legally drunk by adult standards. A single drink may be enough to trigger a violation.
An underage DUI arrest can lead to driver’s license suspension, mandatory DUI school, community service, and in some cases, jail time. The penalties depend on your age, your blood alcohol level, and whether this is your first offense. Even if you are not convicted, the legal process can be confusing, stressful, and filled with long-term risks.
Real Situations That Lead to Underage DUI Charges in St. Petersburg
Many underage DUI cases start with a routine stop on 4th Street North or after an accident near downtown. Police may perform field sobriety tests or request a breathalyzer test. Some arrests happen at parties or during spring break events near the waterfront.
If you are pulled over and suspected of drinking, officers may also investigate for underage drinking or possession of alcohol. In Pinellas County, prosecutors pursue these cases aggressively. A DUI conviction at this age can create serious penalties that affect college admissions, scholarships, and employment opportunities.
Why These Charges Can Alter a Young Person’s Future
An underage DUI conviction often leads to a suspended license and a permanent criminal record. For many young adults, this is their first contact with the legal system. But the penalties can be the same as for adults — and in some ways, more damaging over time.
Florida’s zero tolerance laws are not just about alcohol. Prescription drugs, marijuana, or other substances can also lead to DUI charges for underage drivers. If the blood alcohol level is 0.08 or higher, or if there are multiple offenses, the person may face additional charges like felony DUI or extended license suspension.
