What is an Ignition Interlock Device?
An ignition interlock is a device that prevents a vehicle from starting if the driver has been drinking alcohol. Like a breathalyzer, an ignition interlock measures the alcohol in a person’s system. If that amount exceeds a pre-programmed level, then the interlock will not allow the vehicle to start.
Will the IID shut off or stop my car while I’m driving?
No. Ignition interlock devices prevent the vehicle from starting. Once a vehicle is started, any failed random retest or missed random retest will be reported as a violation and the system’s alarm will activate continuously but it will not shut off the vehicle.
What happens if my ignition interlock equipped vehicle stalls or stops in a dangerous area?
Ignition interlock devices in Oregon State are required to have a two-minute “stall protection” safety window that allows the vehicle to turn back on without providing a breath sample within that period.
How much does an ignition interlock system cost?
The overall cost of an Ignition Interlock Device is a combination of services provided, such as, installation, calibration, and removal. Pricing varies from providers. To find out how much an IID will cost contact a provider.
I have an ignition interlock device requirement, but my interlock-equipped vehicle is in the shop for repair. Can I drive a rental/loaner car without an interlock until my vehicle is fixed?
No. It is a violation of Oregon law for a person with an ignition interlock restriction to operate a motor vehicle that is not equipped with an ignition interlock.
Can someone else drive my vehicle with my device installed?
Yes, but they will need to use the device.
How long do I have to provide a breath sample when the device requests a test?
You have 10 minutes from the time the device alerts for a test to safely pull over and provide a breath sample.
Can I take my device out anytime?
You can have a qualified technician remove your device at your request. However, if the IID requirement is still on your driving record you must have an IID installed in any vehicle you operate.
