What is the Information on an Ignition Interlock Device in Gainesville?

Since July of 2008, installation of an approved ignition interlock device is a mandated or required DUI conviction penalty. Proof of installation must be shown before a person with certain DUI convictions is able to get their diving privilege back. This 2008 mandate applies to all residents of Gainesville, Alachua County and all of Florida.

DUI Convictions that mandate ignition interlock device placement & (the time frame required) are:

  • For a DUI with a BAC (Blood Alcohol Content) over 0.15 (at least 6 months)
  • If there was a minor in the vehicle at the time of the DUI arrest (at least 6 months)
  • For a 2nd DUI conviction (at least one year)
  • For a 2nd DUI conviction with a BAC over 0.15 or if minor in the vehicle (at least 2 years)
  • For a 3rd DUI conviction (at least 2 years)

The device must be approved by the DMV and placed on all vehicles that are individually or jointly owed or leased and routinely operated by the convicted person. Additionally all costs for the purchase, placement and monthly monitoring and calibration are borne by the convicted person. The time periods that are mandated for the device’s placement and use must be consecutive and cannot correspond with imprisonment time.

The ignition interlock device itself plugs into the cigarette lighter of the automobile and is hard-wired to the vehicle’s ignition system. Before the car can be started, the convicted person must blow into the mouthpiece of the device. The machine is similar to other breath testing machines as it reads breath alcohol concentration. The main difference is that this device is used inside the car and will not allow the car to start unless the driver’s breath alcohol level is under a certain concentration. Additionally, periodic breath sampling is required to continue the vehicle’s operation.

The goal of a vehicle ignition interlock device is to prevent a person that has been drinking from starting and then operating a vehicle.
