Ignition Interlock Device Lawyer

When is an ignition interlock required after a DUI in Florida?

An ignition interlock can be required after certain DUI convictions, including those with a breath or blood alcohol level of 0.15 or higher, a minor in the vehicle, or a repeat offense. For a first DUI at 0.15 or higher or with a minor in the vehicle, the requirement is 6 months. In other situations, the length depends on the circumstances.

The requirement follows a conviction, so the outcome of the criminal case directly affects whether an interlock becomes part of a driver's future. Because a 0.15 reading and the presence of a minor both trigger enhanced penalties, those facts are examined closely.

How an interlock device works day to day

An interlock is a breath testing device wired to the vehicle's ignition. The driver provides a breath sample, and the vehicle will not start if the device registers alcohol above its set threshold. The device also keeps a record of its tests.

Living with an interlock involves installation, ongoing use and the end of the requirement period. The details of installation, monitoring and removal depend on the order and the program, so they are explained for each driver's situation rather than in general terms here.

Questioning the 0.15 reading or the minor allegation

Because a reading of 0.15 or higher triggers an interlock on a first offense, the accuracy of that number matters. The Intoxilyzer 8000 is regulated by FDLE, and a 20 minute observation period is required before a breath test. Blood results depend on collection, handling and lab procedures. Each of these can be reviewed before accepting that the 0.15 level was reached.

When the enhancement rests on a minor in the vehicle, who was in the car and their ages are part of the review. A first DUI at 0.15 or higher or with a minor also carries a fine of $1,000 to $2,000 and up to 9 months in jail, so these questions shape the whole case, not just the interlock.

Interlock alongside revocation and reinstatement

An interlock requirement sits alongside other license steps after a conviction: the revocation period, FR-44 proof of insurance, DUI school, and in some cases a hardship or business purposes only license during a suspension. For repeat offenses, the interlock length depends on the circumstances and comes in addition to revocations of at least 5 years for a second DUI within 5 years or at least 10 years for a third within 10 years.

Questions about ignition interlock device

It depends on the facts. For a first DUI at 0.15 or higher or with a minor in the vehicle, Florida requires an ignition interlock for 6 months. Outside those situations, whether a first conviction involves an interlock depends on the circumstances. Because the 0.15 level is often the deciding fact, the breath or blood test behind it is reviewed carefully.

The length depends on the circumstances. An interlock can be required after convictions involving 0.15 or higher, a minor in the vehicle, or repeat offenses, and a first DUI with 0.15 or higher or a minor carries 6 months. The driver's record and the specific conviction shape the period, which is why the full record is reviewed early.

No. The breath test after a DUI arrest is given on the Intoxilyzer 8000, an instrument regulated by FDLE, after a 20 minute observation period. An interlock is a separate device installed in a driver's vehicle after certain convictions. One is evidence in the criminal case, while the other is a condition that can follow a conviction.
