What Are Ignition Interlock Devices?


DUI is a serious offense that can have unintended and tragic impacts on our society. In bad or repeat DUI cases, the driver/defendant will face enhanced sentencing penalties including installation of an ignition interlock device. An ignition interlock device affects those convicted of DUI upon their eligibility for reinstatement of a permanent or restricted driver license. If a person is otherwise eligible, a driver license will be issued with a “P” restriction indicating that an ignition interlock device is required. Drivers who are required to install an ignition interlock device must contact an approved provider, which can be found at the link below:


First conviction: if court ordered
First conviction with 0.15 or minor in vehicle: at least 6 months
Second conviction: at least 1 year
Second conviction with 0.15 or minor in vehicle: at least 2 years
Third conviction: at least 2 years
Four or more convictions: at least 5 years

A second DUI conviction requires mandatory placement of an ignition interlock device for a period of at least 1 year, at the convicted person’s sole expense, upon all vehicles that are individually or jointly leased or owned and routinely operated by the convicted person, when the convicted person qualifies for a permanent or restricted license.  See generally Florida Statute section 316.193(2)(a)3.
