Ignition Interlock Device Information

Section 316.193, Florida Statutes, requires ignition interlock devices to be installed on the vehicles of certain persons convicted of DUI.

The ignition interlock program affects those arrested and convicted of DUI after July 1, 2002, upon eligibility of reinstatement for a permanent or restricted driver license. The ignition interlock device is also required when a driver convicted of DUI applies for a restricted license for work or business purposes (s. 322.271, F.S.). Two ignition interlock vendors (see other side) were selected by the department. The vendors began services February 1, 2004.

If the person is otherwise eligible, a driver license will be issued with a "P" restriction indicating interlock device is required. The required time period for interlock officially begins on the day the "P" interlock restriction is issued.

Court Reporting Requirements

Most courts electronically report DUI convictions to the department. The court order should reflect both the time of suspension and the interlock requirement. Please check with your clerk of court to verify that the electronic reporting from your court includes this ignition interlock requirement.

Costs to the Defendant

The cost (plus tax) to the convicted person for an ignition interlock device is:

$12 Interlock fee
$70 for installation
$67.50 for monthly monitoring and calibration
$100 refundable deposit or a $5 monthly insurance charge

Indigency Guidelines

If the court determines that the convicted person is unable to pay for the installation of the ignition interlock device, the court may order that a portion of the fine paid by the person for a violation of section 316.193 be allocated to defray the costs of installing the device. [s.316.1937(2)(d), Florida Statutes]
