We deal with many DUI bail cases each week so we make it our mission to know all there is to know about drunk driving issues. If you’re familiar with DUI arrests and DUI penalties, you may already know about ignition interlock devices. If not, an ignition interlock device, in short, is a breathalyzer that is installed into the dash of a person’s vehicle that the driver must blow into before the vehicle will start. In order for the convicted DUI offender to drive, the ignition interlock device must detect an acceptable BAC and the offender must blow into the device randomly throughout the duration of the drive. If the resultant breath-alcohol concentration analyzed result is greater than the programmed blood alcohol concentration, which varies from state to state, the device will prevent the engine from being started.

The ignition interlock works by interrupting the signal from the ignition to the starter until a valid breath sample is provided that meets minimal alcohol guidelines specific to the area in which you live. At that point, the vehicle can be started as normal. The purpose of the random checks after the initial sample is to prevent someone other than the driver from providing a breath sample. If the breath sample isn’t provided, or the sample exceeds the ignition interlock’s preset blood alcohol level, the device will also log the event, warn the driver and then sound a car alarm until the ignition is turned off, or a clean breath sample has been provided. A common misconception is that interlock devices will simply turn off the engine if alcohol is detected. Because this would obviously create unsafe driving situations, this is not actually the case. The first performance based interlocks were developed in 1969. In the 1980s, they began to combine these with breathalyzers and state courts began to see their usefulness when it comes to DUI. However, adoption of the device was delayed. In the early 1990s, the industry began to produce “second generation” interlocks with more accurate sensors.

Here in Georgia, there are a number of things that a person can be sentenced to following a DUI conviction, some of which are mandatory and some of which are imposed at the discretion of the judge. The ignition interlock is one of those things. First time DUI offenders don’t need to worry about the possibility of an interlock installation. Those convicted of subsequent DUIs may be subjected to a vehicle device. During the final months of driver’s license suspension, the driver in question is required to have a working ignition interlock device installed in any vehicle that he or she intends to operate, according to Georgia state law.

So that’s the whole idea behind the IID! If you recently received a DUI and need to figure out how to make bail or how to proceed before your trial, one of our qualified bail bond agents can assist you. Call now.
