Two Requirements, Two Clocks
People get this confused all the time. The ignition interlock device and FR-44 insurance are both DUI-related requirements in Florida, but they serve completely different purposes and operate on completely different timelines.
- The interlock is about your car. It’s a breathalyzer wired into your ignition that prevents the vehicle from starting if it detects alcohol. Florida requires it for first-time offenders with a BAC of .15 or higher and for all repeat DUI offenders. (FLHSMV Interlock Program)
- The FR-44 is about you. It’s a certificate proving to the state that you carry the required liability coverage — 100/300/50 — for three continuous years. Your insurance carrier files it electronically with the DHSMV.
Completing your interlock requirement doesn’t shorten your FR-44 obligation. Finishing your FR-44 term doesn’t end your interlock early. They run in parallel, and each has its own clock.
When Does the Interlock Clock Start?
This is where most people lose time without realizing it. Florida doesn’t count your interlock requirement from the day the device is installed in your vehicle. It counts from the day the P restriction gets added to your driver’s license. That’s a separate step — and most people don’t know it exists.
Check your license. Pull up your driving record. If the P restriction isn’t there, your interlock clock hasn’t started — regardless of how long the device has been installed. We’ve talked to people four, five, six months in who were blowing into that thing every morning, paying the lease every month, and as far as the state was concerned, they hadn’t even started.
The P restriction is applied by the DHSMV as part of the reinstatement process. If you install the interlock but haven’t completed the other reinstatement requirements, the restriction won’t be on your license yet — and your time isn’t counting.
Don’t Remove the Interlock Early
You might hear from someone that pulling the interlock device out before your time is up is a good way to save money because “they never check.” They do check. And the consequences are severe: you risk having to surrender your license and start the entire process over again from the beginning.
The interlock provider reports to the DHSMV. Unauthorized removal triggers an automatic notification, and the DHSMV treats it as a violation of your reinstatement terms. The money you save on a few months of device lease is not worth resetting the clock on your license suspension. (Florida Statute §316.1937)
When Does the FR-44 Clock Start?
Your three-year FR-44 requirement starts on your reinstatement date — the day the DHSMV reinstates your driving privileges. Not your arrest date, not your conviction date, and not the day you bought the policy.
Every month you sit on a suspended license is a month added to the back end. That’s why we tell people to work the reinstatement checklist as early as possible — the FR-44 filing is the one piece we can handle in hours, not days. (Florida Statute §324.023)
Once your FR-44 is active, it must remain continuous for the full three years. If the policy lapses for any reason — missed payment, carrier cancellation, anything — the carrier notifies the DHSMV, your license is re-suspended, and the three-year clock can reset.
