A second DUI in Florida carries substantially heavier penalties than a first offense, mandatory ignition interlock regardless of BAC, and a harder suspension period with no hardship license for the first portion. Here’s exactly what you’re facing and how to navigate it.

Second DUI Penalties in Florida

Penalty	Second DUI (5+ years from first)	Second DUI (within 5 years)
Fine	$1,000-$2,000	$1,000-$2,000 (same)
Jail	Up to 9 months	Mandatory 10 days minimum (up to 12 months)
Community service	50 hours	50 hours
Probation	Up to 1 year	Up to 5 years

Vehicle impoundment	30 days	30 days

The 5-Year Lookback Window

In Florida, the 5-year lookback for enhanced second-DUI penalties is calculated from the date of first conviction to the date of second conviction — not from arrest to arrest. A second DUI conviction more than 5 years after the first is still a second offense for criminal purposes, but does not trigger the mandatory 10-day jail minimum or the 5-year revocation. A second conviction within 5 years triggers all enhanced mandatory minimums with no judicial discretion.

The 1-Year Hard Suspension

For a second DUI within 5 years, Florida imposes a 1-year hard suspension — meaning no driving at all, no hardship license, no exceptions. After 1 year, you become eligible to apply for a hardship license with:

• FR44 active (100/300/50)
• IID installed (required for 2 years)
• Level II DUI school enrollment
• Approved substance abuse treatment

FR44 for Second DUI

The FR44 requirement for a second DUI is the same insurance threshold — 100/300/50 — but the 3-year FR44 clock starts from full license reinstatement, which comes later due to the longer revocation period. If you serve a 5-year revocation and then get reinstated, the FR44 runs for 3 years from that reinstatement date — potentially 8 years total from conviction to FR44 completion.

Get FR44 filed as early as possible. Even during the hard suspension period, having FR44 active demonstrates compliance and prepares you for the hardship license application the moment you’re eligible. We file same-day.

Substance Abuse Treatment Requirement

Florida courts almost universally require completion of a substance abuse evaluation and recommended treatment program for second DUI. Level II DUI school includes a 21-hour educational component but may also mandate additional clinical treatment depending on the evaluation outcome. Failure to comply with treatment recommendations can block hardship license eligibility and probation compliance.

The Felony Threshold

Second DUI in Florida is a misdemeanor (unless BAC was very high or serious injury occurred). A third DUI within 10 years of a prior DUI becomes a third-degree felony. A fourth DUI at any time is always a felony. If you have two DUI convictions, a third arrest should be treated as a felony matter immediately — the consequences are categorically different.
