Ignition Interlock Device
If you have been convicted of operating while intoxicated, or OWI, in Iowa, you may be required to install an ignition interlock device for a period of time. An ignition interlock device is connected to the electrical system of your vehicle and prevents the car from starting until your blood alcohol content, tested via your breath, is below a certain limit.
The defendant is required to pay for installation and continued fees for the ignition device. Additionally, the defendant may be restricted in the use of his car to only go to work or substance abuse classes related to the OWI conviction. Although the ignition interlock device can be extremely restrictive, it may be a better option to the outright revocation of all driving privileges.

An ignition interlock device is directly connected to the electrical system in your car and will prevent the car from starting until a blood alcohol content under a certain limit is blown (greater than 0.025 grams per 210 liters of breath). The device must be installed and paid for at the defendant’s expense. The four private companies Iowa has approved to install interlock devices include:

The fee to install an ignition interlock device ranges from $50 to $200 and there is also a monthly rental fee anywhere that can cost from $50 to $100. The interlock device may require maintenance expenses as well as fees to download the data from the device. There will be scheduled times you must have your device recalibrated to maintain the integrity of the device.
An ignition interlock device may be a requirement of a temporary restricted license, a condition of a deferred sentence or a requirement following the revocation of an individual’s license for OWI for a certain period of time.

It is illegal to tamper or bypass an interlock ignition device. Tampering is defined as the attempted or successful circumvention of the proper functioning of an IID including, disabling, disconnecting or altering an IID.
Bypassing the device could include the introduction of a breath sample into an IID other than a non-filtered direct breath sample from the driver of the vehicle in order to defeat the intended purpose of the IID. For example, having a passenger blow into the device would be a form of bypassing it.
The penalty for tampering with an ignition interlock device is a serious misdemeanor punishable by no more than 1 year in jail and a fine ranging from $315 to $1,000.
