How long does a repeat DUII offender need an ignition interlock in Oregon?

ORS 813.602(1)(c) requires the device for two years after the ending date of the suspension or revocation for a second or subsequent conviction. Under ORS 813.602(2), a DUII conviction combined with certain homicide or assault convictions in the same episode, or aggravated vehicular homicide, carries a five-year requirement after the longest-running suspension or revocation ends.

How does the Oregon interlock requirement end?

Under ORS 813.635(1), the requirement continues until the person submits to DMV a certificate from the manufacturer's representative stating the device recorded no negative report for the last 90 consecutive days of the required period. If there is a negative report in that window, § 813.635(2) extends the requirement until a 90-consecutive-day clean certificate is submitted. Oregon DMV describes this as the 90-day No Negative Report.

What does Oregon DMV charge to reinstate after a DUII suspension?

The Oregon DMV hardship permit page lists a reinstatement fee of $85 and a non-refundable hardship permit application fee of $75. DMV Form 735-6826 lists the reinstatement fee, an SR-22 on file for three years, an approved IID for one year (first conviction) or two years (second or subsequent), and a DUII treatment completion certificate as base-license reinstatement requirements.
