Ignition Interlock Devices: Answers to Common Questions

For individuals who have been convicted of a DUI, you might be required to install an ignition interlock device on any vehicle you own or operate as part of your DUI penalty. This instrument, when installed properly, will not cause any permanent damage or affect your car in any way. Its purpose is to screen for alcohol in human breath and, if you exceed a level of 0.01 BAC, your vehicle will not start.

Here are some answers to common questions regarding ignition interlock devices that will help shed some light on your situation:

  • Will an ignition interlock device shut off my car? The ignition interlock device screens for alcohol in your breath when you attempt to start the car and at random intervals while you are driving. However, it will not shut off your car if you test positively while driving since this would pose a danger to you and others on the road. Instead, it will report the positive test result to the service provider and to the court.
  • How much will the ignition interlock device cost me? Remember, this is a form of punishment for your DUI, so you will have to foot the bill for installing this device. Generally, the cost of this device for someone’s first DUI will be within the $500 to $600 range. First, there is an installation fee, which is about $75 and an additional monthly monitoring fee of $75. When you remove the device, there will be another $75. Some vendors might charge a little less, but it not uncommon to spend up to $600 on this device when all is said and done.
  • What is the minimum time for having this device? For a first time offender, the interlock ignition device period is a minimum of 5 months. If it is your second offense, this could increase up to 1 year.
  • What happens if I violate an ignition interlock? One of the most common violations people make is to not install the ignition interlock device and drive anyway. This means they are driving on a suspended license and can end up racking up a new offense. If you fail a rolling test (meaning, you tested positive for alcohol while driving), the penalties can vary, but it is likely the time you are required to have the ignition interlock device will be extended.

The best way to ensure you do not run into any trouble while this device is installed in your car is to simply not get behind the wheel while drinking.
