Florida Ignition Interlock DUI Laws

When you are arrested for a DUI in Florida your license can be suspended in two different ways:

Administrative: This happens if you fail or refuse a breath test. Your license will be immediately suspended or revoked, and the officer at the scene will give you a 10-day temporary driving permit. During this time you can challenge your case. If you do not, or if your challenge is unsuccessful, your license will be suspended automatically on the 11th day for six months.

Criminal: When you are sentenced by a court after a trial or plea agreement, there are additional criminal penalties for DUI. Florida ignition interlock device (IID) laws may require drivers convicted of driving under the influence (DUI) to install an ignition interlock device on every vehicle they own or which is registered to them. Penalties are more severe if blood alcohol concentration (BAC) is .15 or greater, if a minor under 18 years old is a passenger in the vehicle and if there are previous DUI convictions within 10 years. For a 1st offense, you can be ordered to a jail term of up to six months, fines from $500-$1,000, and vehicle impound for 10 days. Attendance at DUI school is mandatory and alcohol abuse evaluation/education may be ordered. A full explanation of DUI laws in Florida, their penalties, and statutory references can be found here.

Pre-Trial Diversion DUI Programs in Florida: Florida counties may offer a pre-trial diversion program for non-felony, 1st time DUI offenders. These programs are directed by the State’s Attorney’s office in the Florida County in which the offense occurred. They typically include education programs and fine requirements and the installation of an ignition interlock.
