Jail time, fines, probation, and driver’s license suspensions are all common penalties for driving under the influence. But did you know that the court can also order the use of an ignition interlock device? Let’s discuss what these machines are used for and whether Florida drivers convicted of DUI are required to use them.

What Is an Ignition Interlock Device?

An ignition interlock device (IID) is a breathalyzer that is installed in a vehicle. When the driver wants to start the car, they must first pass a breath test on the ignition interlock device. If the machine picks up any trace of alcohol in the driver’s breath sample, the car will not start.

If the driver passes the test and can begin driving the car, they should be prepared to continue taking breath tests as they drive. The device will randomly prompt the driver to provide a breath sample while the car is in motion. This is to ensure that the driver did not begin drinking after starting the car, or that they did not have someone else take the breath test in an effort to deceive the IID.

Who Is Required to Use an IID in Florida?

Not all Florida drivers convicted of DUI will be required to use an ignition interlock device. After a standard first-offense DUI conviction, an ignition interlock device is only required if the court orders it. There is no mandatory requirement for a first offense. However, repeat offenses will lead to a period of mandatory ignition interlock device use.

An IID will be required for:

  • One year after a second offense DUI
  • Two years after a third offense DUI
  • At least five years after a fourth or subsequent offense

Additionally, the driver may be required to use an IID for longer periods if their BAC was significantly above the legal limit or if there were other aggravating factors at the time of the offense.
