Disclaimer: This summary was prepared by the Florida Department of Highway Safety and Motor Vehicles (FLHSMV) and should be used for reference only. Please refer to the full text of any laws referenced below for complete and comprehensive legal information.

Section 316.193, Florida Statutes, mandates ignition interlock devices (IID) be installed on the vehicles of certain persons convicted of Driving Under the Influence (DUI).

The IID program affects those arrested and convicted of DUI after July 1, 2002, upon eligibility for reinstatement of a permanent or restricted driver license. The IID is also required when a driver convicted of DUI applies for a restricted license for work or business purposes, as authorized in section 322.271, Florida Statutes.

If a person is otherwise eligible, a driver license will be issued with a “P” restriction indicating an IID is required. The required time period for an IID begins on the day the “P” restriction is issued.

Court Reporting Requirements
Most courts electronically report DUI convictions to the FLHSMV. The court order should reflect both the time of the suspension and the IID requirement. Please verify with the clerk of court that the court’s electronic reporting includes this IID requirement.


Indigent Guidelines
If the court determines that the convicted person is unable to pay for the installation of the IID, the court may order that a portion of the fine paid by the person for a violation of section 316.193, Florida Statutes, be allocated to defray the cost of installation.
