How Iowa OWI courts are organised
A OWI charge in Iowa is prosecuted in the District Court that serves the county or municipality where the stop happened, not where you live. The clerk's office in that courthouse controls your hearing dates, accepts motions and continuances, and takes payment of fines and court costs. Calendars, filing hours and remote-appearance rules differ from courthouse to courthouse, so confirm them with the clerk before your first date.
Iowa's district court hears every OWI case: a first offense is a serious misdemeanor, a second is an aggravated misdemeanor, and a third or later offense is a Class 'D' felony. Appeals go to the Iowa Court of Appeals, with further review by the Iowa Supreme Court.

What happens at each stage in Iowa
A OWI case in Iowa is heard in the District Court, and it runs on two tracks at once: the criminal case and a separate licence action you must challenge within 10 days of arrest.
- 1Arrest, booking and the chemical test — Officers arrest for OWI under Iowa Code § 321J.2 and request a breath, blood or urine test under Iowa's implied-consent section, Iowa Code § 321J.6. Refusing carries its own licence penalty, separate from the criminal charge.
- 2Licence action — request a hearing within 10 days — The DOT revokes driving privileges administratively after an OWI arrest, independent of any conviction. You have 10 days from arrest to demand the administrative hearing with Iowa Department of Transportation, Driver and Identification Services; miss it and the suspension takes effect automatically, whatever happens in court.
- 3Arraignment in the District Court — The charge is read, a plea is entered and conditions of release are set in the District Court. Iowa's district court hears every OWI case: a first offense is a serious misdemeanor, a second is an aggravated misdemeanor, and a third or later offense is a Class 'D' felony.
- 4Pretrial motions and discovery — Defence counsel obtains the police report, test records and calibration or maintenance logs, and may move to suppress the stop or the test result. Iowa courts file through the Judicial Branch's Electronic Document Management System.
- 5Diversion or treatment disposition — A deferred judgment under Iowa Code § 907.3 is available to eligible first-time OWI defendants.
- 6Plea or trial, then sentencing — A first OWI conviction carries a fine of $625–$1,875, jail exposure up to 1 year, a licence suspension of 6 months, an ignition interlock requirement. Prior offenses within 12 years push the case into the enhanced-penalty range. A first offense carries a mandatory minimum jail term and interlock for early reinstatement.
- 7Reinstatement — The $200 civil penalty under Iowa Code § 321J.17 must be paid before reinstatement or a temporary restricted licence. Iowa requires a SR-22 certificate of financial responsibility for 2 years before the licence is restored.
