Florida Ignition Interlock Resource
If a court or the Florida DHSMV has told you that you need an ignition interlock device, you probably have a lot of questions. What is the device, how does it work, how long will you need it, and what will it cost? This site is an independent informational resource that walks through those questions in plain language, so you can understand the process before you commit to anything.
An ignition interlock device, often shortened to IID, is a small breath-testing unit connected to a vehicle's ignition system. Before the engine will start, the driver provides a breath sample. If the sample shows alcohol above a preset level, the vehicle will not start. In Florida, interlock devices are commonly required after certain DUI convictions as a condition of getting back on the road with a restricted license.
Interlock rules are set state by state, and so are licensing courses. Florida has its own course for first-time drivers, while New York requires new drivers to complete a 5 hour pre licensing course before the road test.

Who this site is for
This resource is written for Florida drivers who are facing an interlock requirement for the first time, and for family members trying to help someone through the process. It is general information, not legal advice. Every case is different, and requirements can change, so always confirm the details of your own situation with the court, the DHSMV, or a licensed attorney.
Choosing a five-hour class online lets busy learners complete the required training without visiting a classroom.
When a family member takes over the driving
An interlock requirement often affects more than one person. Before a driver returns to the road on a restricted license, with a breath test before every start, there can be a stretch with no driving at all. During that time, a spouse, parent or adult child may end up handling the drives to work, school and the grocery store.
Sometimes that person holds a valid license but has not driven regularly in years, perhaps because someone else always did the driving. Picking it back up in busy traffic, with new responsibilities attached, is a lot to take on at once.
If that family member lives in south Miami-Dade, PalmWay Driving School offers lessons in Pinecrest for returning drivers. The instructor picks up at home, school or work, starts on quiet village streets and adds US-1 and the Palmetto Expressway only when the driver is ready. Each 60-minute lesson is private and one-on-one, in a dual-control car, in English or Spanish.
