Ignition Interlock Devices in Florida

An ignition interlock device is a device that attaches to the convicted DUI offender’s car, truck or motor vehicle of any kind and only allows the motor vehicle to start if the driver performs a breath-test into the device and exhibits no sign of alcohol in the driver’s blood system. Many times, an ignition interlock device is used when a driver convicted of a DUI applies for a restricted license for work or business purposes. The fine for an ignition interlock device is approximately $250. This covers the cost of installation, monthly monitoring and calibration and refundable deposit in case of damages. The ignition interlocks device prevents the start of a vehicle if the driver’s breath sample has a BAC of 0.05 or above. The ignition interlock device operates on fuel cell technology and is able to conduct rolling tests of random testing while the driver is in the process of driving motor vehicles. The driver’s BAC is reported to the web and is monitored 24 hours a day and seven days a week. Upon a first-time DUI conviction, an ignition interlock device is required if court ordered. Upon a first-time DUI conviction with a BAC of .15 or above, or with minor in the car the court requires an ignition interlock device to be installed for a period of at least six months. For a second DUI conviction, the court requires that an ignition interlock device be installed for a period of at least one year. For a second-time DUI conviction with a BAC of 0.15 or more or with a minor in the car the court requires that the ignition interlock device be installed in the driver’s car for a period of at least two years. For a third conviction of DUI, the court requires that an ignition interlock device be installed for a period of at least two years. For a fourth conviction of a DUI, the court requires that an ignition interlock device be installed in the driver’s motor vehicle for a period of at least five years.
