Are IIDs Required After a Florida DUI?

By Jonathan Blecher on April 2, 2019

“What is an Ignition Interlock Device (IID)?” It’s a small breathalyzer device that’s installed into someone’s vehicle. IIDs are available in different shapes and sizes, but they’re about the size of a cellphone or a television remote control.

In order for the vehicle to start, the driver has to blow an alcohol-free breath sample. If their breath is good, the vehicle will start normally. But if there is alcohol in the person’s breath, the vehicle won’t start for a set period of time.

People who have been convicted of driving under the influence (DUI) and ordered to install an IID will have to provide breath samples throughout their trip to ensure they aren’t drinking and driving.

If the driver blows into the IID while driving and it detects alcohol, the vehicle won’t stop in the middle of the roadway, but the horn
will blow and the lights will start flashing to signal the driver to pull over and stop driving.

Who Has to Have an IID in Florida?

Some states require that all DUI defendants install IIDs, even for first DUI offenses, but that is not necessarily the case in Florida. Under Section 316.193 of the Florida Statutes, an IID is required under the following circumstances:

  • First conviction: If the court orders it.
  • First conviction with a blood alcohol content (BAL) of 0.15 or more: A minimum of six months.
  • First conviction with a minor in the vehicle: A minimum of six months.
  • Second conviction: A minimum of one year.
  • Second conviction with a high BAL (0.15 or above): A minimum of two years.
  • Third DUI conviction: A minimum of two years.
  • Four or more DUI convictions: A minimum of five years.

In addition to the above, an IID is required if someone is convicted of DUI and wishes to apply for a restricted driver license for work or business purposes. If the individual is approved for a restricted license, they will receive a driver license with a “P” restriction, which indicates that they must have an IID.
