Oregon Ignition Interlock — Requirements & Costs
When interlock may be required and practical steps.
When Oregon requires an IID §813.602
generally required for 1 year after suspension ends for a first conviction (statutory exemptions apply); required for hardship permit.
How long the IID must remain installed
1 year after suspension/revocation ends for first conviction; 2 years for second or subsequent; longer periods apply in specified aggravated cases or restored permanent revocation — confirm the current period with a lawyer.
How the device works in practice
Violations and extensions
Common violations that can extend the IID period or trigger additional consequences:
- Failed startup tests (BAC above threshold)
- Failed rolling retests
- Missed calibration appointments
- Tampering with or attempting to circumvent the device
- Operating a vehicle without an IID when one is required
Costs
IID costs are borne by the offender and include:
- Installation fee
- Monthly monitoring/rental fee
- Removal fee
- Calibration fees (may be included in monthly rental or charged separately)
The IID as a path back to driving
While the IID is a restriction, it is also the mechanism that allows many offenders to resume driving sooner than they would under a full suspension. In Oregon, Hardship permit with IID available after 30 days hard suspension for first offense. Complying fully with IID requirements — no violations, on-time calibration — is the fastest path to full reinstatement.
