Second & Third DUI Defense

Florida's DUI statute is built as a ladder: every prior conviction — from any state, from any decade — raises the mandatory floor of the next one. A second DUI can mean required jail and years without a full license; a third can be a felony; a fourth is a felony no matter how old the priors are. The dates of your prior convictions are now as important as the facts of the new arrest, and both deserve a hard look before anyone talks about a plea.

​

Second DUI

• Fine: $1,000–$2,000 ($2,000–$4,000 with a .15+ reading or a minor in the vehicle).

• Jail: up to 9 months (up to 12 with the enhancement). If the second conviction is within 5 years of the first, at least 10 days in jail is mandatory, 48 hours of it consecutive.

• License: a second conviction within 5 years brings a 5-year revocation (hardship eligibility after 1 year). Outside 5 years, the revocation is 6 months to 1 year.

• Ignition interlock for at least 1 year (2 years with the enhancement), 30-day vehicle impoundment, DUI school Level II, and probation.

​

Third DUI

• Within 10 years of a prior conviction: a third-degree felony — up to 5 years in state prison — with a mandatory minimum of 30 days in jail, a 10-year license revocation (hardship after 2 years), a 90-day impoundment, and at least 2 years of ignition interlock.

• More than 10 years after any prior: a first-degree misdemeanor with a $2,000–$5,000 fine, up to 12 months in jail, and the same 2-year interlock requirement.

The 10-year math is measured conviction-to-conviction, and out-of-state priors count only if they qualify — two of the most litigated issues in felony DUI cases.

​

Fourth or Subsequent DUI

A fourth conviction is a third-degree felony regardless of when the priors occurred, with a minimum $2,000 fine — and it triggers permanent license revocation. For many clients a fourth DUI case is really a fight about the rest of their driving life, and occasionally about habitual offender sentencing exposure beyond the 5-year statutory maximum.

​

The Prior-Conviction Battleground

Felony DUI prosecutions require the State to prove the priors — properly counseled, properly documented convictions that qualify under Florida law. Old out-of-state cases, uncounseled pleas, “zero tolerance” administrative actions, and record-keeping gaps give the defense real openings: knocking out one prior can turn a felony into a misdemeanor and erase a mandatory minimum. At the same time, every defense available in a first DUI — the stop, the exercises, the breath machine — still applies to the new case. A multiple-DUI defense runs on both tracks at once.

​

Beyond the Courtroom

Repeat-DUI clients face consequences that need managing alongside the case: FR-44 insurance, employment and CDL fallout, interlock logistics, and — realistically — the question of treatment. Where alcohol is genuinely the issue, documented, voluntary treatment is both the right move and the most persuasive mitigation that exists in a Florida DUI courtroom. We help clients do it on their terms, before the State imposes it on its own.

Frequently Asked Questions

My prior DUI was 7 years ago. Is a second conviction mandatory jail?

No — the mandatory 10 days applies when the second conviction comes within 5 years of the first. Outside 5 years, jail is possible but not mandated, and the license consequences are far lighter.

Does my out-of-state DUI count?

Only if it qualifies as a conviction under Florida's rules — a document-intensive question that is frequently worth litigating, because the entire felony enhancement can rest on it.

Can a felony DUI be reduced back to a misdemeanor?

Yes — by defeating a prior, by negotiation, or by beating the new case outright. It happens regularly with the right record work.

Is treatment going to be forced on me?

A conviction requires evaluation and any recommended treatment. Getting ahead of it voluntarily usually produces both a better outcome and a better result in the case.

The Floor Is Set by Law — the Ceiling by the Defense

Mandatory minimums only apply if the State proves everything: the stop, the impairment, and the priors. Call or text 407-846-8008 for a free consultation with former prosecutor Chad Seibel. Office visits are by appointment only.
