An ignition interlock device (IID) is an unique mechanism that works just like a breathalyzer, but it is installed in a vehicle’s dashboard to prevent the driver from drinking and driving.
How Does It Work?
Before the driver can start the car, they must give a breath sample into the device, and if the result is greater than the device’s pre-programmed blood alcohol concentration level, the device “locks” the vehicle from being started. After some time, the driver can provide another breath sample and if it meets the minimal alcohol guidelines (which can vary by state and country), the vehicle then “unlocks” and can start as normal.
After the engine has been turned on, the IID will randomly request samples throughout the driver’s commute; the purpose is to prevent someone other than the driver from falsifying a breath sample. If one isn’t provided, or if the sample exceeds the IID’s presets, the device will then log the event, warn the driver, and start up an alarm (horn honking and lights flashing) until the driver can get off the road and the engine has been turned off or until a clean breath sample can be provided.
How Is It Monitored?
The data collected by the IID is then sent to whomever ordered the device to be installed, such as the DMV, the Court, probation officer, etc.. Many states require the data to be sent directly through wireless technology as soon as a sample is taken, while some states receive the information infrequently, but no less than once a month.
The Cost Of An IID
Having an IID installed is often a condition of driving again if the person’s license was suspended as a result of a DUI conviction. The cost of having an IID isn’t cheap, as an installation can cost anywhere from $100-$200, and a monthly rental fee can range from $70 to $100. This does not include any additional charges for routine maintenance or having the device regulated frequently.
There’s no fooling the device either, and if a sober friend takes the test for the driver, or if the driver tampers with the device, it can lead to more legal trouble and a possibility of revoking their license indefinitely.
