An OWI conviction in Iowa stays on your criminal record permanently, and on your driving record for at least 12 years. Those two timelines do different work. The criminal record is what a background check pulls up. The driving record is what a prosecutor and judge use to decide whether a new arrest counts as a first, second, or third offense.
The 12-Year Driving Record Window
Iowa decides whether you are a repeat OWI offender by looking at your motor vehicle operating record. If a prior OWI conviction or deferred judgment still appears there, it counts. Once it has been removed, it doesn’t.1Justia Law. Iowa Code 321J.2 – Operating While Under the Influence of Alcohol or a Drug or While Having an Alcohol Concentration of .08 or More (OWI) The Iowa DOT removes OWI revocations from the operating record after 12 years, which is where the commonly cited 12-year lookback comes from.
What that means in practice: a conviction from nine years ago still exposes you to second-offense penalties if you’re arrested today. A conviction from 13 years ago that has already been cleared from your driving record leaves a new charge to be treated as a first offense for sentencing. One detail trips people up. A deferred judgment for OWI also counts as a prior offense during that window, even though the underlying charge was dismissed and the record expunged.1Justia Law. Iowa Code 321J.2 – Operating While Under the Influence of Alcohol or a Drug or While Having an Alcohol Concentration of .08 or More (OWI) The public record disappears; the enhancement system remembers.
The Criminal Record Is Permanent
The criminal record created by an OWI conviction has no expiration date in Iowa. Iowa keeps most criminal records public, and the court docket is searchable online at no cost.2Iowa Legal Aid. Can I Expunge My Adult Criminal Conviction in Iowa? Any employer, landlord, or lender running a background check will see it. The 12-year window that controls sentencing has nothing to do with this. Fifteen years after your conviction, a new arrest would be charged as a first offense, but the old conviction is still right there on your criminal history.
Federal law doesn’t help much either. The Fair Credit Reporting Act caps how long arrests without convictions can appear on a consumer background report at seven years. Criminal convictions, including OWI convictions, carry no federal time limit.3Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports A consumer reporting agency can keep reporting an OWI conviction indefinitely. Some states impose their own look-back limits on employers; Iowa does not.
The Only Way to Clear It: Deferred Judgment
If you were convicted of OWI in Iowa, there is currently no mechanism to expunge that conviction. The only route to a cleared record is to have received a deferred judgment in the first place. With a deferred judgment, the court withholds entering a conviction and puts you on probation. Complete probation, pay everything owed, and the case is dismissed and the record is expunged.4Justia Law. Iowa Code 907.9 – Discharge From Probation – Procedure – Expungement of Deferred Judgments Once expunged, the record becomes confidential and drops out of public view.
For OWI deferred judgments, expungement is automatic on discharge from probation and payment of court-ordered financial obligations. You don’t file a separate petition, and there is no additional waiting period.4Justia Law. Iowa Code 907.9 – Discharge From Probation – Procedure – Expungement of Deferred Judgments
Qualifying is the hard part. You are ineligible for a deferred judgment on an OWI if any of the following apply:5Justia Law. Iowa Code 907.3 – Deferred Judgment, Deferred Sentence, or Suspended Sentence
- Your blood alcohol concentration exceeded .15.
- You have a prior OWI conviction or deferred judgment, in Iowa or any other state.
- You refused the chemical test.
- Someone other than you was injured.
- You were driving on a barred license at the time.
In practice that leaves deferred judgment available only to genuine first-time offenders who tested at or below .15, submitted to the chemical test, and caused no injury.
Consequences That Don’t Follow the 12-Year Clock
Two consequences of an Iowa OWI don’t line up with the driving-record timeline, and they catch people who assume the problem goes away once the record is cleared for sentencing purposes.
Commercial Driver’s License
Federal law requires a minimum one-year disqualification from operating commercial vehicles after a first alcohol-related offense, whether you were in a commercial or personal vehicle at the time. Carrying hazardous materials pushes that to three years. A second offense results in lifetime CDL disqualification.6eCFR. 49 CFR 383.51 – Disqualification of Drivers The federal rule runs on its own track, independent of what Iowa’s driving record shows years later.
Entry Into Canada
Canada can refuse entry to a U.S. visitor with an impaired driving conviction. Since December 2018, Canada’s maximum penalty for impaired driving is ten years, which reclassified it as a serious crime under Canadian immigration law. For offenses on or after December 18, 2018, the “deemed rehabilitation” pathway is no longer available, and entering Canada requires applying for criminal rehabilitation or a temporary resident permit. For older offenses, deemed rehabilitation may apply once ten years have passed since you completed every element of your sentence. Border agents have access to U.S. criminal databases, so an Iowa OWI can surface at the border decades after the fact.
The short version: for sentencing on a future Iowa charge, the clock is roughly 12 years. For a background check, there is no clock at all unless you received a deferred judgment and completed it. And some consequences, like CDL disqualification and Canadian border inadmissibility, follow their own federal and foreign rules that pay no attention to when Iowa clears your driving record.
