An ignition interlock device (IID) is a breathalyzer installed in your vehicle that prevents the engine from starting if alcohol is detected on your breath. In Washington, these devices are mandatory for most DUI convictions, and understanding the requirements can help you prepare for what’s ahead.
Who Must Install An Ignition Interlock Device?
Washington state law requires an IID for nearly all DUI convictions. The requirements vary based on the circumstances of your case. If you’re convicted of a first-offense DUI, you’ll need an IID installed for at least one year. This applies even if your blood alcohol concentration (BAC) was just slightly over the legal limit of 0.08%. The Washington State Department of Licensing oversees the IID program and maintains a list of approved vendors. For second or subsequent DUI offenses, the installation period extends significantly. You may face a five-year or even 10-year IID requirement depending on how many prior convictions appear on your record within seven years. A Bellevue first offense DUI lawyer can help you understand the specific timeline that applies to your situation and whether any exceptions might reduce the installation period.
What Triggers An IID Requirement?
Several factors determine whether you’ll need an ignition interlock device:
- A DUI conviction with any BAC level
- Refusal to submit to a breath or blood test
- A BAC of 0.15% or higher
- Having a minor passenger in the vehicle during the arrest
- Multiple DUI offenses within seven years
How Long Does The Device Stay Installed?
The minimum installation period depends on your offense. For a first DUI conviction with a BAC between 0.08% and 0.14%, you’re looking at one year with the device. If your BAC was 0.15% or higher, the period remains one year for a first offense, but subsequent violations carry much longer requirements. Second offenses typically require five years with an IID. Third and subsequent offenses may require 10 years or potentially a lifetime installation, depending on the circumstances and your driving history. The clock doesn’t start until you actually have the device installed and functioning properly. If you delay installation, you’re only extending the period before you can drive without restrictions again.
Can You Drive Without An IID?
Once the court orders an IID installation, driving any vehicle without one becomes illegal. This includes borrowed cars, rental vehicles, and company cars. The only exception is if you hold an IID-restricted license that specifically permits driving vehicles equipped with the device. Violating this restriction can result in additional criminal charges, extended IID requirements, and further license suspensions. The penalties stack quickly, making compliance the only practical option.
The Installation Process
You’ll need to choose from a list of state-approved vendors. The device gets professionally installed in your vehicle, and you’ll receive training on how to use it properly. Monthly calibration appointments are mandatory to verify that the device functions correctly. These appointments typically cost between $60 and $100, and you’re responsible for all installation and maintenance fees. Most vendors charge an initial installation fee plus monthly monitoring costs. Working with a Bellevue first offense DUI lawyer from the start can sometimes help minimize the installation period or explore alternative sentencing options in your case.
