Preventing DUI Arrests: Understanding Florida’s Ignition Interlock Device Program

In Florida, efforts to curb DUI (Driving Under the Influence) incidents have led to the implementation of the Ignition Interlock Device (IID) program. This program is a critical tool in preventing DUI arrests and promoting safe driving. This article delves into the workings of the IID program in Florida, its requirements, and its role in DUI prevention.

What is an Ignition Interlock Device?

An Ignition Interlock Device is a breathalyzer for an individual’s vehicle. It requires the driver to provide a breath sample before the engine will start. If the device detects a blood alcohol concentration (BAC) above a pre-set limit, typically 0.02% or higher in Florida, the vehicle will not start.

Florida’s Ignition Interlock Device Program

The IID program in Florida is a legal requirement in specific DUI cases. It is primarily used for:

  • Repeat DUI Offenders: Individuals with multiple DUI convictions are often required to install an IID in their vehicles.
  • High BAC Levels: Drivers convicted of DUI with a BAC significantly above the legal limit (0.08% in Florida) may also be mandated to use the device.
  • DUI Involving Minors: If the DUI offense involved a minor in the vehicle, the court might order the installation of an IID.

The Process of Obtaining an IID

  • Court Order or DMV Requirement: Installation of an IID is typically ordered by the court or the Department of Motor Vehicles (DMV) as part of DUI sentencing or reinstatement of driving privileges.
  • Selecting a Provider: Individuals must choose an IID provider from a list approved by the Florida DMV.
  • Installation and Monitoring: The device must be professionally installed, and data from the IID is periodically reviewed for compliance.

Costs and Responsibilities

The cost of an IID, which includes installation, monthly rental, and maintenance, is borne by the individual required to use it. Users are also responsible for regular maintenance and ensuring that the device is functioning correctly.

Legal Implications of IID Non-Compliance

Non-compliance with the IID program can result in further legal consequences, such as:

  • Extension of the IID requirement period.
  • Revocation of driving privileges.
  • Additional legal penalties or fines.

Benefits of the IID Program

  • DUI Prevention: By preventing operation of the vehicle if the driver is impaired, IIDs significantly reduce the likelihood of repeat DUI offenses.
  • Behavioral Change: The program encourages individuals to modify their behavior and make safer driving decisions.
  • Public Safety: IIDs contribute to overall road safety by deterring impaired driving.


Florida’s Ignition Interlock Device program is an effective measure in the fight against DUI offenses. Understanding this program is essential for individuals who find themselves facing DUI charges and for the broader community in promoting safe driving habits. The IID program not only serves as a deterrent but also as a rehabilitative tool, aiding individuals in making responsible choices and ultimately contributing to the safety of Florida’s roads.
