For a first DUII conviction, you’ll need to use the device for one year after your license suspension ends. If you violate this requirement, it’s a serious traffic offense. For a second or subsequent DUII conviction, you’ll need to use the device for two years after your suspension ends. Again, breaking this rule is a serious traffic offense.
If you’re convicted of specific serious crimes along with a DUII, like murder or manslaughter, you’ll have to use the device for five years after your longest suspension ends. Breaking this rule is also a significant traffic offense.
If you’re in a DUII diversion program, the court might require you to install an Ignition Interlock Device in your car, depending on your blood alcohol level or if you refused a test. Violating this requirement is also a Class A traffic offense. There might be medical exemptions available, but they need to follow the rules set by the Department of Transportation.
If you’re required to have an Ignition Interlock Device, the company that installs it must notify the court, the prosecutor, and the Oregon State Police if the device is tampered with or removed.
