A first OWI in Iowa: what it can result in

Iowa writes the floor into the offense: a first OWI carries a minimum period of imprisonment in the county jail of forty-eight hours, and a ceiling of one year. Time already spent in custody after the arrest counts against it, and so does time in a court-ordered OWI program with law enforcement security. The court may fit the sentence around your work schedule — that discretion is in the statute — but it cannot go below the two days. The fine is fixed rather than banded at $1,250, and with the consent of the defendant the court may defer judgment, which is the route most first offenses actually take.

Start from what the statute forces and what it leaves to the judge. The floor here is at least 48 hours, up to one year. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.

Serious misdemeanor: at least 48 hours, up to one year, and a fine of $1,250. The range is set by Iowa Code § 321J.2(2)(a), (3)(a), (3)(c), and the figures on this page come from the statute rather than from a summary of it.

Iowa revokes your driving privileges after an OWI whether or not the court convicts you. The way back is a temporary restricted license, and on a first offense you need a device on every vehicle you drive to get one. A medical waiver exists for offenses from 1 January 2025, verified by a doctor. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by Iowa DOT, Motor Vehicle Division.
