Ignition Interlock Device Program
The Oregon Department of Transportation is the regulatory authority of ignition interlock devices, interlock service technicians and interlock service centers throughout the State of Oregon. The Ignition Interlock Device Oversight program of the Oregon Department of Transportation is operated out of the Transportation Safety Division and consists of law enforcement officers and support staff dedicated to ignition interlock device standardization, service center compliance, and public safety.

 
A breath alcohol ignition interlock device (BAIID or simply IID) is attached to the ignition of a motor vehicle and is designed to prevent a motor vehicle from being operated by a person who has consumed an alcoholic beverage. When properly installed and calibrated, the IID will prevent a driver from starting a motor vehicle if the device detects a breath alcohol concentration (BAC​​) above the prescribed setpoint.
