Will I have to get an ignition interlock device after a DUI?

Ignition interlock device laws are common across all states in the country, but understanding the laws pursuant to Florida is paramount. If the Florida courts convict you of DUI, depending on your situation you may need to install an ignition interlock device if you wish to continue operating motor vehicles.

However, you may not need to install an ignition interlock device in all cases. According to the Florida Department of Highway Safety and Motor Vehicles, if you have a very high BAC for your first DUI conviction or if the courts find you guilty of subsequent DUI convictions, you must install an ignition interlock device.

What does an ignition interlock device do?

Essentially, an ignition interlock device hooks into the starter system of your car. When you want to start your car, you must breathe into the device. If the device finds any alcohol on your breath, your car will not be able to start.

When you are driving, you must breathe periodically into the device as indicated. In the event that the ignition interlock device detects alcohol on your breath while you are driving, it will set off the alarm system in your car. This will get the attention of law enforcement.

How long must I have an ignition interlock device?

This depends on the nature of your DUI case. For a first conviction with a blood alcohol level above 0.15, you must have an ignition interlock device for a minimum of six months. For a second conviction, it is a minimum of one year. The number of years you must have an ignition interlock device goes up along with the frequency of your DUI convictions.
